1.  Do experiences of racial discrimination predict cardiovascular disease among African American Men? The moderating role of internalized negative racial group attitudes 
Social science & medicine (1982)  2010;71(6):1182-1188.
Studies examining associations between racial discrimination and cardiovascular health outcomes have been inconsistent, with some studies finding the highest risk of hypertension among African Americans who report no discrimination. A potential explanation of the latter is that hypertension and other cardiovascular problems are fostered by internalization and denial of racial discrimination. To explore this hypothesis, the current study examines the role of internalized negative racial group attitudes in linking experiences of racial discrimination and history of cardiovascular disease among African American men. We predicted a significant interaction between reported discrimination and internalized negative racial group attitudes in predicting cardiovascular disease. Weighted logistic regression analyses were conducted among 1216 African American men from the National Survey of American Life (NSAL; 2001– 2003). We found no main effect of racial discrimination in predicting history of cardiovascular disease. However, agreeing with negative beliefs about Blacks was positively associated with cardiovascular disease history, and also moderated the effect of racial discrimination. Reporting racial discrimination was associated with higher risk of cardiovascular disease among African American men who disagreed with negative beliefs about Blacks. However, among African American men who endorsed negative beliefs about Blacks, the risk of cardiovascular disease was greatest among those reporting no discrimination. Findings suggest that racial discrimination and the internalization of negative racial group attitudes are both risk factors for cardiovascular disease among African American men. Furthermore, the combination of internalizing negative beliefs about Blacks and the absence of reported racial discrimination appear to be associated with particularly poor cardiovascular health. Steps to address racial discrimination as well as programs aimed at developing a positive racial group identity may help to improve cardiovascular health among African American men.

2.  Adapting the Everyday Discrimination Scale to Medical Settings: Reliability and Validity Testing in a Sample of African American Patients 
Ethnicity & disease  2011;21(4):502-509.
Despite evidence that discrimination within the health care system may play an important role in perpetuating health disparities, instruments designed to measure discrimination within the health care setting have not been adequately tested or validated. Consequently, we sought to test the psychometric properties of a modified version of the Everyday Discrimination scale, adapted for medical settings.
Cross-sectional study.
Academic medical center in Chicago.
Seventy-four African American patients.
Outcome measures
We measured factor analysis, internal consistency, test-retest reliability, convergent validity and discriminant validity.
Seventy-four participants completed the baseline interviews and 66 participants (89%) completed the follow-up interviews. Eighty percent were women. The Discrimination in Medical Settings (DMS) Scale had a single factor solution (eigenvalue of 4.36), a Cronbach’s alpha of 0.89 and test-retest reliability of .58 (P<.0001). The DMS was significantly correlated with an overall measure of societal discrimination (EOD) (r=.51, P<.001) as well as two of its three subscales (unfair: r=−.04, P=.76; discrimination: r=.45, P<0.001; worry: r=−.36, P=.002). The DMS was associated with the overall African American Trust in Health Care Scale (r=.27, P=.02) as well as two key subscales (racism: r=.31, P<.001; disrespect: r=.44, P<.001). The DMS scale was inversely associated with the Social Desirability Scale (r=.18, P=.13). The DMS scale was not correlated with the Center for Epidemiologic Studies Depression Scale (r=.03, P=.80).
The Discrimination in Medical Settings Scale has excellent internal consistency, test-retest reliability, convergent validity and discriminant validity among our sample of African American patients. Further testing is warranted among other racial/ethnic groups.

3.  Ethnic, Racial and Cultural Identity and Perceived Benefits and Barriers Related to Genetic Testing for Breast Cancer among At-Risk Women of African Descent in New York City 
Public Health Genomics  2011;14(6):356-370.
Due to disparities in the use of genetic services, there has been growing interest in examining beliefs and attitudes related to genetic testing for breast and/or ovarian cancer risk among women of African descent. However, to date, few studies have addressed critical cultural variations among this minority group and their influence on such beliefs and attitudes.
We assessed ethnic, racial and cultural identity and examined their relationships with perceived benefits and barriers related to genetic testing for cancer risk in a sample of 160 women of African descent (49% self-identified African American, 39% Black-West Indian/Caribbean, 12% Black-Other) who met genetic risk criteria and were participating in a larger longitudinal study including the opportunity for free genetic counseling and testing in New York City. All participants completed the following previously validated measures: (a) the multi-group ethnic identity measure (including ethnic search and affirmation subscales) and other-group orientation for ethnic identity, (b) centrality to assess racial identity, and (c) Africentrism to measure cultural identity. Perceived benefits and barriers related to genetic testing included: (1) pros/advantages (including family-related pros), (2) cons/disadvantages (including family-related cons, stigma and confidentiality concerns), and (3) concerns about abuses of genetic testing.
In multivariate analyses, several ethnic identity elements showed significant, largely positive relationships to perceived benefits about genetic testing for breast and/or ovarian cancer risk, the exception being ethnic search, which was positively associated with cons/disadvantages, in general, and family-related cons/disadvantages. Racial identity (centrality) showed a significant association with confidentiality concerns. Cultural identity (Africentrism) was not related to perceived benefits and/or barriers.
Ethnic and racial identity may influence perceived benefits and barriers related to genetic testing for breast and/or ovarian cancer risk among at-risk women of African descent. Genetic counseling services may want to take into account these factors in the creation of culturally-appropriate services which best meet the needs of this heterogenous population.

4.  Reliability of Internet- Versus Telephone-Administered Questionnaires in a Diverse Sample of Smokers 
Smoking is more prevalent among lower-income individuals and certain racial/ethnic minorities. Addressing tobacco cessation among diverse populations is an urgent public health priority. As Internet use continues to rise among all segments of the US population, Web-based interventions have enormous potential to reach priority populations. Conducting Web-based smoking cessation research in priority populations requires psychometrically sound measurement instruments. To date, only one published study has examined the psychometric properties of Internet-administered measures commonly used in Web-based cessation trials. However, the sample was homogeneous with regard to race/ethnicity and income. We sought to replicate and extend these findings in a more diverse sample of smokers.
The aim was to examine the internal consistency and test-retest reliability of measures commonly used in smoking cessation clinical trials among racial/ethnic minorities and smokers with lower income.
Participants were enrolled in a randomized trial of the efficacy of an Internet smoking cessation program between June 2005 and September 2006. Following a baseline telephone assessment and randomization into the parent trial, participants were recruited to the reliability substudy. In phase I of recruitment, all participants in the parent trial were recruited to the substudy; in phase II, all consecutive racial/ethnic minority participants in the parent trial were recruited. Race and ethnicity were assessed via self-report using two standard items from the US Office of Management and Budget. An email was sent 2 days after the telephone assessment with a link to the Internet survey. Measures examined were quit methods, perceived stress, depression, social support, smoking temptations, alcohol use, perceived health status, and income. Internal consistency and test-retest reliability of Internet- versus telephone-administered measures were examined within four strata defined by race/ethnicity (non-Hispanic White, racial/ethnic minority) and annual household income (US $40,000 or less, more than $40,000).
Of the 442 individuals invited, 319 participated (72% response rate): 52.4% were non-Hispanic White, 22.9% Black, 11.6% Hispanic, 7.8% Asian, 4.4% American Indian / Alaska Native, and 1% Native Hawaiian / Other Pacific Islander. About half (49.4%) reported an annual household income of US $40,000 or less, and 25.7% had a high school degree or less. Test-retest reliability was satisfactory to excellent across all strata for the majority of measures examined: 9 of 12 continuous variables had intraclass correlation coefficients ≥ 0.70, and 10 of 18 binary variables and both ordinal variables had kappa coefficients ≥ 0.70. Test-retest reliability of several quit methods varied across strata.
Race/ethnicity and income do not affect the psychometric properties of most Internet-administered measures examined. This knowledge adds to the confidence of conducting Web-based smoking cessation research and strengthens the scientific rigor of collecting information via the Internet on racial/ethnic minority and low-income subgroups.

5.  The Utility of Cancer-Related Cultural Constructs to Understand Colorectal Cancer Screening Among African Americans 
Data suggest that colorectal cancer could be cut by approximately 60% if all people aged 50 years or older received regular screening. Studies have identified socio-cultural attitudes that might inform cancer education and screening promotion campaigns. This article applies item response theory (IRT) to a set of survey items selected to assess sociocultural attitudes in order to determine how current measures may affect what we know about how these attitudes affect colorectal cancer screening (CRCS).
Design and Methods
A survey of colorectal cancer screening, screening attitudes and cultural beliefs was administered to 1021 African Americans – 683 women and 338 men, ages 50 to 75. Eligibility criteria for participation included being born in the United States, self-identified African American male or female, age 50 to 75 years. The IRT analysis was performed on 655 individuals with complete data for the 43 observed variables.
Twenty-nine items comprise the Multi-construct African American Cultural Survey (MAACS) that addresses seven cultural constructs: mistrust/distrust, privacy, ethnic identity, collectivism, empowerment, and male gender roles. The items provide adequate information about the attitudes of the population across most levels of the constructs assessed. Among the sociocultural variables considered, empowerment (OR=1.078; 95% CI: 1.008, 1.151) had the strongest association with CRCS adherence and privacy showed promise.
The MAACS provides a fixed length questionnaire to assess African American CRCS attitudes, two new constructs that might assist in CRCS promotion, and a suggested focus for identification of additional constructs of interest.
Significance for public healthThe 29 items of the Multi-construct African American Cultural Survey, identified through IRT analyses, can be used by community health researchers interested in determining the relevance of cultural constructs in the design and implementation of colorectal cancer screening programs in the African American community. With appropriate identification of sociocultural concerns, CRC health education materials and promotion strategies may avoid unnecessary conflicts with community beliefs and values. Avoiding conflicts between beliefs and values increases the likelihood that evidence and the recommended behaviours are considered for adoption. In addition, the short survey, as well as the broader item set, may be useful as a starting point for surveys to be used with other cancer sites. The application of IRT analysis to measures of cultural constructs to facilitate the development of accurate and efficient measures may prove useful in other racial/ethnic communities where cultural concerns may be relevant for health education and promotion.

6.  Medical Evidence of Human Rights Violations against Non-Arabic-Speaking Civilians in Darfur: A Cross-Sectional Study 
PLoS Medicine  2012;9(4):e1001198.
Alexander Tsai and colleagues review medical records from the Amel Centre, Sudan, to assess consistency between recorded medical evidence and patient reports of human rights violations by the Government of Sudan and Janjaweed forces.
Ongoing conflict in the Darfur region of Sudan has resulted in a severe humanitarian crisis. We sought to characterize the nature and geographic scope of allegations of human rights violations perpetrated against civilians in Darfur and to evaluate their consistency with medical examinations documented in patients' medical records.
Methods and Findings
This was a retrospective review and analysis of medical records from all 325 patients seen for treatment from September 28, 2004, through December 31, 2006, at the Nyala-based Amel Centre for Treatment and Rehabilitation of Victims of Torture, the only dedicated local provider of free clinical and legal services to civilian victims of torture and other human rights violations in Darfur during this time period. Among 325 medical records identified and examined, 292 (89.8%) patients from 12 different non-Arabic-speaking tribes disclosed in the medical notes that they had been attacked by Government of Sudan (GoS) and/or Janjaweed forces. Attacks were reported in 23 different rural council areas throughout Darfur. Nearly all attacks (321 [98.8%]) were described as having occurred in the absence of active armed conflict between Janjaweed/GoS forces and rebel groups. The most common alleged abuses were beatings (161 [49.5%]), gunshot wounds (140 [43.1%]), destruction or theft of property (121 [37.2%]), involuntary detainment (97 [29.9%]), and being bound (64 [19.7%]). Approximately one-half (36 [49.3%]) of all women disclosed that they had been sexually assaulted, and one-half of sexual assaults were described as having occurred in close proximity to a camp for internally displaced persons. Among the 198 (60.9%) medical records that contained sufficient detail to enable the forensic medical reviewers to render an informed judgment, the signs and symptoms in all of the medical records were assessed to be consistent with, highly consistent with, or virtually diagnostic of the alleged abuses.
Allegations of widespread and sustained torture and other human rights violations by GoS and/or Janjaweed forces against non-Arabic-speaking civilians were corroborated by medical forensic review of medical records of patients seen at a local non-governmental provider of free clinical and legal services in Darfur. Limitations of this study were that patients seen in this clinic may not have been a representative sample of persons alleging abuse by Janjaweed/GoS forces, and that most delayed presenting for care. The quality of documentation was similar to that available in other conflict/post-conflict, resource-limited settings.

Editors' Summary
Conflict in the Darfur region of Sudan between Arabic- and non-Arabic-speaking tribes over the past decade has resulted in a severe humanitarian crisis. According to the United Nations, more than 2.7 million people have fled from their homes to camps for internally displaced persons (IDPs) or to refugee camps in neighboring Chad, and up to 300,000 people have died from war, hunger, and disease since the conflict started. The origins of this conflict go back many years, but in 2003, organized rebel forces began attacking government targets, accusing the Government of Sudan (GoS) of oppressing black Africans in favor of Arabs. In response, the GoS attacked the rebel forces, but some observers allege it also targeted non-Arabic-speaking civilians, in contravention of international laws of war. Observers have also accused the GoS of having links with the Janjaweed militias, nomadic Arabs who attack settled black farmers, although the GoS denies any such links. Indeed, reports of systematic, targeted assaults on non-Arabic-speaking civilians, of large-scale disruption of rural livelihoods, and of deliberate consignment to living conditions likely to cause death have prompted some observers to accuse the GoS of genocide (violent crimes committed against a national, ethnical, racial, or religious group with the intention of destroying that group) and the International Criminal Court to issue arrest warrants for the allegedly responsible authorities.
Why Was This Study Done?
Most investigations of claims of violence against civilians in Darfur have relied on self-reported data gathered from people living in refugee camps outside Sudan. Because these data could be biased, in this cross-sectional study (a study that characterizes a population at a single point in time), the researchers investigate the nature and geographic scope of alleged abuses against civilians in Darfur and endeavor to substantiate these allegations by analyzing the medical records of patients attending the Amel Centre for Treatment and Rehabilitation of Victims of Torture in Nyala, South Darfur. Opened in 2004, this center provided free clinical and legal services to civilians affected by human rights violations. Its staff fled in 2009 because of increasingly dangerous working conditions; the medical records used in this study were sent out of Sudan before the staff fled.
What Did the Researchers Do and Find?
Between September 28, 2004, and December 31, 2006, 325 patients were seen at the Amel Centre. According to their medical records, 292 patients from 12 different non-Arabic-speaking tribes alleged that they had been attacked by GoS or Janjaweed forces in rural areas across Darfur. Nearly all the patients reported that they had been attacked in the absence of active armed conflict between GoS/Janjaweed forces and rebel groups. Half of them claimed that they had been beaten, two-fifths reported gunshot wounds, a third reported destruction or theft of property, and nearly a third reported involuntary detainment. Half of the 73 women seen at the center disclosed that they had been sexually assaulted, often near IDP camps. Only 198 medical records contained sufficient detail to enable the researchers to determine whether the documented medical evidence was consistent with the alleged abuses. However, in all these cases, the researchers judged that the medical evidence was consistent with, highly consistent with, or virtually diagnostic of the alleged abuses.
What Do These Findings Mean?
These findings provide credible medical evidence that is consistent with torture and other human rights violations being inflicted on non-Arabic-speaking civilians in Darfur from 2004 to 2006. These findings cannot be used to estimate the population incidence of attacks on civilians or to corroborate claims of assailants' identities or of genocidal intent. Moreover, their accuracy may be affected by several limitations of this study. For example, during the study period, only patients who obtained a medical evidence form from the police were permitted to receive treatment from an authorized medical officer; obtaining such a form likely represented a considerable hurdle to accessing health care services. Nevertheless, the widespread, organized, and sustained pattern of attacks documented in this study is consistent with the possibility that the actions of Janjaweed and GoS forces during the conflict in Darfur may constitute war crimes, crimes against humanity, and/or acts of genocide. Importantly, these findings also highlight the need to provide adequate protection for health professionals working in countries affected by internal conflicts.

7.  Validation of the Group-Based Medical Mistrust Scale Among Urban Black Men 
Socioculturally relevant measures of medical mistrust are needed to better address health disparities, especially among Black men, a group with lower life expectancy and higher death rates compared to other race/gender groups.
The study aim was to investigate the psychometric properties of the Group-Based Medical Mistrust Scale (GBMMS) in a Black male sample.
Data were collected as part of a randomized controlled trial testing educational strategies to support Black men’s decisions about prostate cancer screening.
Participants included 201 Black men ages 40–75 years recruited in New York City during 2006–2007.
The primary measures included: race-based medical mistrust, health care participation, avoidance of health care, perceived access to health care, health care satisfaction, racial identity, residential racial segregation, attitudes towards prostate cancer screening, and past prostate cancer screening behavior.
An exploratory factor analysis suggested a three-factor structure. Confirmatory factor analysis supported the three-factor model. Internal consistency was high for the total GBMMS and the three sub-scales: Suspicion, Discrimination, and Lack of Support. Construct validity was supported by: significant positive correlations between GBMMS and avoidance of health care and racial identity as well as significant negative correlations with health care access, health care satisfaction, pt?>and attitudes about prostate cancer screening. ANOVA showed that the GBMMS was associated with greater residential racial segregation. Higher total GBMMS scores were associated with not visiting a physician in the last year and not having a regular physician.
The present findings provide strong additional evidence that the GBMMS is a valid and reliable measure that may be used among urban Black men.

8.  The Multigroup Ethnic Identity Measure-Revised: Measurement invariance across racial and ethnic groups 
Journal of counseling psychology  2013;61(1):154-161.
The Multigroup Ethnic Identity Measure-Revised (MEIM-R), a brief instrument assessing affiliation with one’s ethnic group, is a promising advance in the ethnic identity literature. However, equivalency of its measurement properties across specific racial and ethnic groups should be confirmed before using it in diverse samples. We examined a) the psychometric properties of the MEIM-R including factor structure, measurement invariance, and internal consistency reliability, and b) levels of and differences in ethnic identity across multiple racial and ethnic groups and subgroups. Asian (n = 630), Black/African American (n = 58), Hispanic (n = 240), multiethnic (n = 160), and White (n = 375) women completed the MEIM-R as part of the “Gestational diabetes’ Effect on Moms” diabetes prevention trial in the Kaiser Permanente Northern California health care setting (N = 1,463; M age 32.5 years, SD = 4.9). Multiple-groups confirmatory factor analyses provided provisional evidence of measurement invariance, i.e., an equal, correlated two-factor structure, equal factor loadings, and equal item intercepts across racial and ethnic groups. Latent factor means for the two MEIM-R subscales, exploration and commitment, differed across groups; effect sizes ranging from small to large generally supported the notion of ethnic identity as more salient among people of color. Pending replication, good psychometric properties in this large and diverse sample of women support the future use of the MEIM-R. Preliminary evidence of measurement invariance suggests that the MEIM-R could be used to measure and compare ethnic identity across multiple racial and ethnic groups.

9.  A New Audience Segmentation Tool for African Americans: The Black Identity Classification Scale 
Journal of health communication  2010;15(5):532-554.
Many health communications target African Americans in an attempt to remediate race-based health disparities. Such materials often assume that African Americans are culturally homogeneous; however, research indicates that African Americans are heterogeneous in their attitudes, behaviors, and beliefs. The Black Identity Classification Scale (BICS) was designed as a telephone-administered tool to segment African American audiences into 16 ethnic identity types. The BICS was pretested using focus groups, telephone pretests, and a pilot study (n=306). The final scale was then administered to 625 Black adults participating in a dietary intervention study, where it generally demonstrated good internal consistency reliability. The construct validity of the BICS was also explored by comparing participants’ responses to culturally associated survey items. The distribution of the 16 BICS identity types in the intervention study is presented, as well as select characteristics for participants with core identity components. Although additional research is warranted, these findings suggest that the BICS has good psychometric properties and may be an effective tool for identifying African American audience segments.

10.  Implicit Racial Bias as a Moderator of the Association Between Racial Discrimination and Hypertension: A Study of Midlife African American Men 
Psychosomatic medicine  2012;74(9):961-964.
Empirical findings on racial discrimination and hypertension risk have been inconsistent. Some studies have found no association between self-reported experiences of discrimination and cardiovascular health outcomes while others have found moderated or curvilinear relationships. The current cross-sectional study examined whether the association between racial discrimination and hypertension is moderated by implicit racial bias among African American midlife men.
This study examined data on 91 African American men between 30-50 years of age. Primary variables were self-reported experiences of racial discrimination; and unconscious racial bias as measured by the Black-White Implicit Association Test. Modified Poisson regression models were specified examining hypertension, defined as mean resting systolic ≥ 140 mm Hg or diastolic ≥ 90 mm Hg; or self-reported history of cardiovascular medication use with a physician diagnosis of hypertension.
No main effects for discrimination or implicit racial bias were found, but the interaction of the two variables was significantly related to hypertension (χ2 = 4.89, 1 df, p < 0.05). Among participants with an implicit anti-Black bias, more frequent reports of discrimination were associated with a higher probability of hypertension, while among those with an implicit pro-Black bias, it was associated with lower risk.
The combination of experiencing racial discrimination and holding an anti-Black bias may have particularly detrimental consequences for hypertension among African American midlife men, while holding an implicit pro-Black bias may buffer the effects of racial discrimination. Efforts to address both internalized racial bias and racial discrimination may lower cardiovascular risk in this population.

11.  Psychometric Properties of Self-Report Concussion Scales and Checklists 
Journal of Athletic Training  2012;47(2):221-223.
Alla S, Sullivan SJ, Hale L, McCrory P. Self-report scales/checklists for the measurement of concussion symptoms: a systematic review. Br J Sports Med. 2009;43 (suppl 1):i3–i12.
Clinical Question:
Which self-report symptom scales or checklists are psychometrically sound for clinical use to assess sport-related concussion?
Data Sources:
Articles available in full text, published from the establishment of each database through December 2008, were identified from PubMed, Medline, CINAHL, Scopus, Web of Science, SPORTDiscus, PsycINFO, and AMED. Search terms included brain concussion, signs or symptoms, and athletic injuries, in combination with the AND Boolean operator, and were limited to studies published in English. The authors also hand searched the reference lists of retrieved articles. Additional searches of books, conference proceedings, theses, and Web sites of commercial scales were done to provide additional information about the psychometric properties and development for those scales when needed in articles meeting the inclusion criteria.
Study Selection:
Articles were included if they identified all the items on the scale and the article was either an original research report describing the use of scales in the evaluation of concussion symptoms or a review article that discussed the use or development of concussion symptom scales. Only articles published in English and available in full text were included.
Data Extraction:
From each study, the following information was extracted by the primary author using a standardized protocol: study design, publication year, participant characteristics, reliability of the scale, and details of the scale or checklist, including name, number of items, time of measurement, format, mode of report, data analysis, scoring, and psychometric properties. A quality assessment of included studies was done using 16 items from the Downs and Black checklist1 and assessed reporting, internal validity, and external validity.
Main Results:
The initial database search identified 421 articles. After 131 duplicate articles were removed, 290 articles remained and were added to 17 articles found during the hand search, for a total of 307 articles; of those, 295 were available in full text. Sixty articles met the inclusion criteria and were used in the systematic review. The quality of the included studies ranged from 9 to 15 points out of a maximum quality score of 17. The included articles were published between 1995 and 2008 and included a collective total of 5864 concussed athletes and 5032 nonconcussed controls, most of whom participated in American football. The majority of the studies were descriptive studies monitoring the resolution of concussive self-report symptoms compared with either a preseason baseline or healthy control group, with a smaller number of studies (n = 8) investigating the development of a scale.
The authors initially identified 20 scales that were used among the 60 included articles. Further review revealed that 14 scales were variations of the Pittsburgh Steelers postconcussion scale (the Post-Concussion Scale, Post-Concussion Scale: Revised, Post-Concussion Scale: ImPACT, Post-Concussion Symptom Scale: Vienna, Graded Symptom Checklist [GSC], Head Injury Scale, McGill ACE Post-Concussion Symptoms Scale, and CogState Sport Symptom Checklist), narrowing down to 6 core scales, which the authors discussed further. The 6 core scales were the Pittsburgh Steelers Post-Concussion Scale (17 items), Post-Concussion Symptom Assessment Questionnaire (10 items), Concussion Resolution Index postconcussion questionnaire (15 items), Signs and Symptoms Checklist (34 items), Sport Concussion Assessment Tool (SCAT) postconcussion symptom scale (25 items), and Concussion Symptom Inventory (12 items). Each of the 6 core scales includes symptoms associated with sport-related concussion; however, the number of items on each scale varied. A 7-point Likert scale was used on most scales, with a smaller number using a dichotomous (yes/no) classification.
Only 7 of the 20 scales had published psychometric properties, and only 1 scale, the Concussion Symptom Inventory, was empirically driven (Rasch analysis), with development of the scale occurring before its clinical use. Internal consistency (Cronbach α) was reported for the Post-Concussion Scale (.87), Post-Concussion Scale: ImPACT 22-item (.88–.94), Head Injury Scale 9-item (.78), and Head Injury Scale 16-item (.84). Test-retest reliability has been reported only for the Post-Concussion Scale (Spearman r = .55) and the Post-Concussion Scale: ImPACT 21-item (Pearson r = .65). With respect to validity, the SCAT postconcussion scale has demonstrated face and content validity, the Post-Concussion Scale: ImPACT 22-item and Head Injury Scale 9-item have reported construct validity, and the Head Injury Scale 9-item and 16-item have published factorial validity.
Sensitivity and specificity have been reported only with the GSC (0.89 and 1.0, respectively) and the Post-Concussion Scale: ImPACT 21-item when combined with the neurocognitive component of ImPACT (0.819 and 0.849, respectively). Meaningful change scores were reported for the Post-Concussion Scale (14.8 points), Post-Concussion Scale: ImPACT 22-item (6.8 points), and Post-Concussion Scale: ImPACT 21-item (standard error of the difference = 7.17; 80% confidence interval = 9.18).
Numerous scales exist for measuring the number and severity of concussion-related symptoms, with most evolving from the neuropsychology literature pertaining to head-injured populations. However, very few of these were created in a systematic manner that follows scale development processes and have published psychometric properties. Clinicians need to understand these limitations when choosing and using a symptom scale for inclusion in a concussion assessment battery. Future authors should assess the underlying constructs and measurement properties of currently available scales and use the ever-increasing prospective data pools of concussed athlete information to develop scales following appropriate, systematic processes.

12.  Performance of the CJDATS Co-Occurring Disorders Screening Instruments (CODSIs) among Minority Offenders 
Behavioral sciences & the law  2008;26(4):351-368.
Previous research has shown the performance of the CJDATS Co'-Occurring Disorders Screening Instruments (CODSI-MD and SMD)—six- and three-item instruments to screen for any mental disorder (CODSI-MD) and for severe mental disorders (CODSI-SMD), respectively—to be comparable or superior to other, longer instruments. This study tested the stability of the performance of the CODSI-MD and SMD across three racial/ethnic groups of offenders entering prison substance abuse treatment programs (n = 353), consisting of 96 African American, 120 Latino, and 137 White admissions. The Structured Clinical Interview (SCID) was used to obtain DSM-IV Axis I and II diagnoses; a lifetime SCID diagnosis of a mental disorder or a severe mental disorder was the criterion against which the CODSI-MD and SMD were validated. Results showed no statistical differences in sensitivity or specificity for either the CODSI-MD or SMD across the African American, Latino, and White prisoner groups. The value of the CODSI-MD and SMD as brief screens for mental disorders among offenders with diverse racial/ethnic backgrounds is discussed.

13.  Reliability and Validity of the Perspectives of Support From God Scale 
Nursing research  2010;59(2):102-109.
Existing spiritual support scales for use with cancer survivors focus on the support believed to come from a religious community, clergy, or health care providers.
The objective of this study was to evaluate the reliability and validity of a new measure of spiritual support believed to come from God in older Christian African American cancer survivors.
The Perceived Support From God Scale was administered to 317 African American cancer survivors aged 55–89 years. Psychometric evaluation involved identifying underlying factors, conducting item analysis and estimating reliability, and obtaining evidence on the relationship to other variables or the extent to which the Perceived Support From God Scale correlates with religious involvement and depression.
The Perceived Support From God Scale consists of 15 items in two subscales (Support From God and God’s Purpose for Me). The two subscales explained 59% of the variance. Cronbach’s α coefficients were .94 and .86 for the Support From God and God’s Purpose for Me subscales, respectively. Test–retest correlations were strong, supporting the temporal stability of the instrument. Pearson’s correlations to an existing religious involvement and beliefs scale were moderate to strong. Subscale scores on Support From God were negatively correlated to depression.
Initial support for reliability and validity was demonstrated for the Perceived Support From God Scale. The scale captures a facet of spirituality not emphasized in other measures. Further research is needed to evaluate the scale with persons of other racial/ethnic groups and to explore the relationship of spirituality to other outcome measures.

14.  Scale Development for Measuring and Predicting Adolescents’ Leisure Time Physical Activity Behavior 
The aim of this study was to develop a scale for assessing and predicting adolescents’ physical activity behavior in Spain and Luxembourg using the Theory of Planned Behavior as a framework. The sample was comprised of 613 Spanish (boys = 309, girls = 304; M age =15.28, SD =1.127) and 752 Luxembourgish adolescents (boys = 343, girls = 409; M age = 14.92, SD = 1.198), selected from students of two secondary schools in both countries, with a similar socio-economic status. The initial 43-items were all scored on a 4-point response format using the structured alternative format and translated into Spanish, French and German. In order to ensure the accuracy of the translation, standardized parallel back-translation techniques were employed. Following two pilot tests and subsequent revisions, a second order exploratory factor analysis with oblimin direct rotation was used for factor extraction. Internal consistency and test-retest reliabilities were also tested. The 4-week test-retest correlations confirmed the items’ time stability. The same five factors were obtained, explaining 63.76% and 63.64% of the total variance in both samples. Internal consistency for the five factors ranged from α = 0.759 to α = 0. 949 in the Spanish sample and from α = 0.735 to α = 0.952 in the Luxembourgish sample. For both samples, inter-factor correlations were all reported significant and positive, except for Factor 5 where they were significant but negative. The high internal consistency of the subscales, the reported item test-retest reliabilities and the identical factor structure confirm the adequacy of the elaborated questionnaire for assessing the TPB-based constructs when used with a population of adolescents in Spain and Luxembourg. The results give some indication that they may have value in measuring the hypothesized TPB constructs for PA behavior in a cross-cultural context.
Key pointsWhen using the structured alternative format, weak internal consistency was obtained. Rephrasing the items and scoring items on a Likert-type scale enhanced greatly the subscales reliability.Identical factorial structure was extracted for both culturally different samples.The obtained factors, namely perceived physical competence, parents’ physical activity, perceived resources support, attitude toward physical activity and perceived parental support were hypothesized as for the original TPB constructs.

15.  Validation of an Instrument to Assess Evidence-Based Practice (EBP) Knowledge, Attitudes, Access and Confidence 
Journal of dental education  2011;75(2):131-144.
This paper reports the validation of an assessment instrument designed to measure the outcomes of training in evidence-based practice (EBP) within the context of dentistry. Four EBP dimensions are measured by this instrument: (1) understanding of EBP concepts, (2) attitudes about EBP, (3) evidence accessing methods, and, (4) confidence in critical appraisal. The instrument is the Evidence Based Practice Knowledge, Attitudes, Access, and Confidence Evaluation (KACE) that has four scales, totaling 35 items: EBP knowledge (10), EBP attitudes (10), accessing evidence (9) and confidence in critical appraisal (6).
Four elements of validity were assessed: consistency of items within the KACE scales (extent to which items within a scale measure the same dimension), discrimination (capacity to detect differences between individuals with different training or experience), responsiveness (capacity to detect the effects of education on trainees) and test-retest reliability. Internal consistency of scales was assessed by analyzing responses from KACEs completed by second year dental students, dental residents and dental school faculty using Cronbach alpha. Discriminative validity was assessed by comparing KACE scores for students, residents and faculty members. Responsiveness was assessed by comparing pre - and post - training responses for dental students and residents. To measure test-retest reliability, the KACE was completed twice by a class of freshmen dental students 17 days apart and the knowledge scale was completed twice by 16 dental faculty 14 days apart.
Item - to - scale consistency ranged from 0.21 to 0.78 for knowledge, 0.57 to 0.83 for attitude, 0.70 to 0.84 for accessing evidence and 0.87 to 0.94 for confidence. For discrimination, ANOVA and post-hoc testing by the Tukey-Kramer method revealed significant score differences among students, residents and faculty consistent with education and experience levels. For responsiveness to training, dental students and residents demonstrated statistically significant changes, in desired directions, from pre - to post - test. For the student test-retest, Pearson correlations for KACE scales were: knowledge (0.66), attitudes (0.66), evidence accessing (0.74) and confidence (0.76). For the knowledge scale test-retest by faculty, the Pearson correlation was 0.79.
The construct validity of the KACE is equivalent to that of instruments that assess similar EBP dimensions in medicine. Item consistency for the knowledge scale was more variable than for other KACE scales, a finding also reported for medically-oriented EBP instruments. The KACE has good discriminative validity, responsiveness to training effects, and test-retest reliability.

16.  Measuring Multiple Minority Stress: The LGBT People of Color Microaggressions Scale 
Lesbian, gay, and bisexual individuals who are also racial/ethnic minorities (LGBT-POC) are a multiply marginalized population subject to microaggressions associated with both racism and heterosexism. To date, research on this population has been hampered by the lack of a measurement tool to assess the unique experiences associated with the intersection of these oppressions. To address this gap in the literature, we conducted a three-phase, mixed method empirical study to assess microaggressions among LGBT-POC. The LGBT People of Color Microaggressions Scale is an 18-item self-report scale assessing the unique types of microaggressions experienced by ethnic minority LGBT adults. The measure includes three subscales: (a) Racism in LGBT communities, (b) Heterosexism in Racial/Ethnic Minority Communities, and (c) Racism in Dating and Close Relationships, that are theoretically consistent with prior literature on racial/ethnic minority LGBTs and have strong psychometric properties including internal consistency and construct validity in terms of correlations with measures of psychological distress and LGBT-identity variables. Men scored higher on the LGBT-PCMS than women, lesbians and gay men scored higher than bisexual women and men, and Asian Americans scored higher than African Americans and Latina/os.

17.  Validation of a Measure to Assess Alcohol- and Marijuana-Related Risks and Consequences Among Incarcerated Adolescents* 
Drug and alcohol dependence  2010;109(1-3):104-113.
Few measures exist to assess risky behaviors and consequences as they relate to substance use in juvenile delinquents. This study sought to validate such a measure on a racially and ethnically diverse sample (N = 175). Results indicate that alcohol-related risky behaviors and consequences comprise a single scale as do marijuana-related risky behaviors and consequences. Furthermore, results suggest that the retention of common items for both scales produces reliable and valid scales and maintains parsimony. Internal consistencies were more than adequate (0.72 – 0.83) and test-retest stabilities, even across several months were acceptable (0.52 - 0.50). The scales evidenced a high degree of concurrent and predictive incremental validity in predicting conduct disorder, dependence symptoms, and consumption patterns. Researchers can use these scales to measure a generalized construct tapping risks and consequences as related to alcohol and marijuana use. Ease of use may make these scales appealing to clinicians who can provide feedback to clients regarding risky behaviors involving alcohol and marijuana.

18.  Development and Testing of the Health Care System Distrust Scale 
Distrust of the health care system may be a significant barrier to seeking medical care, adhering to preventive health care and treatment regimens, and participating in medical research.
To describe the development and psychometric testing of an instrument (the Health Care System Distrust Scale) to measure distrust of the health care system.
Scale development involved 2 phases. In Phase 1, a pilot instrument was developed based on a conceptual model of health care-related distrust. Draft items were created using focus group sessions with members of the general public, literature review, and expert opinion. Draft items were pilot tested with 55 individuals waiting to be assigned to jury duty at the Municipal Court of Philadelphia. A priori, candidate items for elimination or revision included those with >5% missing data, extremely low or high interitem or item-total correlations, or those having a negative effect on the scale's internal consistency. In Phase 2, we conducted a survey of 400 prospective jurors to assess the reliability and validity of the final scale scores.
In Phase 1, a 10-item scale was constructed that included 4 items measuring honesty, 2 items measuring confidentiality, 2 items measuring competence, and 2 items measuring fidelity. The participants in Phase 2 had a mean age of 41 years. Forty-three percent were African-American, 45% white, and 4% Hispanic. Scores on the Health Care System Distrust scale ranged from 12 to 46 with a possible range from 10 to 50. The mean score was 29.4 with a standard deviation of 6.33. No item had over 5% missing data. Internal consistency (Cronbach's α) was 0.75. Item-total correlations ranged from 0.27 to 0.57. Principal components analysis revealed 1 general component accounting for 32% of the variance. Nine of the variables had loadings higher than 0.40. As predicted, distrust of the health care system was higher among African Americans than whites and was inversely correlated with trust in personal physicians.
Initial testing suggests that we developed an instrument with valid and reliable scores in order to measure distrust of the health care system. Future research is needed to evaluate the validity and reliability of the Health Care System Distrust scale among diverse populations. This instrument can facilitate the investigation of the prevalence, causes, and effects of health care system distrust in the United States.

19.  Perceptions of Racism in Children and Youth (PRaCY): Properties of a Self-Report Instrument for Research on Children's Health and Development 
Ethnicity & health  2010;15(1):33-46.
Experiences of racial discrimination have been demonstrated to be related to racial and ethnic disparities in mental and physical health and healthcare. There has been little study, however, of the relationship between racism and health in children, and few psychometrically valid and reliable instruments to measure perceptions of racism in children and youth exist. This paper reports on the development and testing of such an instrument, the Perceptions of Racism in Children and Youth (PRaCY).
Development of the instrument began with open-ended qualitative interviews, from which a proto-questionnaire was created. The questionnaire gathered information on the prevalence, attribution, emotional responses and coping responses to 23 situations identified by participants in the qualitative phase. The proto-questionnaire was administered to 277 children between the ages of 8-18 years (38% Latino/a, 31% African American, 19% Multi-racial/Multi-cultural, 7% West Indian/Caribbean, 5% Other). Item analysis resulted in two developmentally-appropriate 10-item instruments (one for ages 7-13, one for ages 14-18). Internal consistency reliability was strong (alpha = 0.78 for both versions of the instrument). Confirmatory factor analysis demonstrated good fit for both versions (younger- CFI: 0.967, RMSEA 0.047; older-CFI: 0.934, RMSEA: 0.056). Differential item functioning analyses demonstrated no group-specific biases in item response. PRaCY scores were appropriately associated with higher depressive symptom scores and elevated anxiety scores in the younger sample.
Results indicate that the PRaCY is a valid and reliable instrument that measures perceptions of racism and discrimination in children and youth ages 8-18 from diverse racial/ethnic backgrounds.

20.  Cross-cultural adaptation of the short-form condom attitude scale: validity assessment in a sub-sample of rural-to-urban migrant workers in Bangladesh 
BMC Public Health  2013;13:240.
The reliable and valid measurement of attitudes towards condom use are essential to assist efforts to design population specific interventions aimed at promoting positive attitude towards, and increased use of condoms. Although several studies, mostly in English speaking western world, have demonstrated the utility of condom attitude scales, very limited culturally relevant condom attitude measures have been developed till to date. We have developed a scale and evaluated its psychometric properties in a sub-sample of rural-to-urban migrant workers in Bangladesh.
This paper reports mostly on cross-sectional survey components of a mixed methods sexual health research in Bangladesh. The survey sample (n = 878) comprised rural-to-urban migrant taxi drivers (n = 437) and restaurant workers (n = 441) in Dhaka (aged 18–35 years). The study also involved focus group sessions with same populations to establish the content validity and cultural equivalency of the scale. The current scale was administered with a large sexual health survey questionnaire and consisted of 10 items. Quantitative and qualitative data were assessed with statistical and thematic analysis, respectively, and then presented.
The participants found the scale simple and easy to understand and use. The internal consistency (α) of the scale was 0.89 with high construct validity (the first component accounted for about 52% of variance and second component about 20% of the total variance with an Eigen-value for both factors greater than one). The test-retest reliability (repeatability) was also found satisfactory with high inter-item correlations (the majority of the intra-class correlation coefficient values was above 2 and was significant for all items on the scale, p < 0.001). The 2-week repeatability assessed by the Pearson product–moment correlation coefficient was 0.75.
The results indicated that Bengali version of the scale have good metric properties for assessing attitudes toward condom use. Validated scale is a short, simple and reliable instrument for measuring attitudes towards condom use in vulnerable populations like current study sample. This culturally-customized scale can be used to monitor the progress of condom uptake and promotion activities in Bangladesh or similar settings.

21.  Validation of an abbreviated Treatment Satisfaction Questionnaire for Medication (TSQM-9) among patients on antihypertensive medications 
The 14-item Treatment Satisfaction Questionnaire for Medication (TSQM) Version 1.4 is a reliable and valid instrument to assess patients' satisfaction with medication, providing scores on four scales – side effects, effectiveness, convenience and global satisfaction. In naturalistic studies, administering the TSQM with the side effects domain could provoke the physician to assess the presence or absence of adverse events in a way that is clinically atypical, carrying the potential to interfere with routine medical care. As a result, an abbreviated 9-item TSQM (TSQM-9), derived from the TSQM Version 1.4 but without the five items of the side effects domain was created. In this study, an interactive voice response system (IVRS)-administered TSQM-9 was psychometrically evaluated among patients taking antihypertensive medication.
A total of 3,387 subjects were invited to participate in the study from an online panel who self-reported taking a prescribed antihypertensive medication. The subjects were asked to complete the IVRS-administered TSQM-9 at the start of the study, along with the modified Morisky scale, and again within 7 to 14 days. Standard psychometric analyses were conducted; including Cronbach's alpha, intraclass correlation coefficients, structural equation modeling, Spearman correlation coefficients and analysis of covariance (ANCOVA).
A total of 396 subjects completed all the study procedures. Approximately 50% subjects were male with a good racial/ethnic mix: 58.3% white, 18.9% black, 17.7% Hispanic and 5.1% either Asian or other. There was evidence of construct validity of the TSQM-9 based on the structural equation modeling findings of the observed data fitting the Decisional Balance Model of Treatment Satisfaction even without the side effects domain. TSQM-9 domains had high internal consistency as evident from Cronbach's alpha values of 0.84 and greater. TSQM-9 domains also demonstrated good test-retest reliability with high intraclass correlation coefficients exceeding 0.70. As expected, the TSQM-9 domains were able to differentiate between individuals who were low, medium and high compliers of medication, with moderate to high effect sizes. There was evidence of convergent validity with significant correlations with the medication adherence scale.
The IVRS-administered TSQM-9 was found to be a reliable and valid measure to assess treatment satisfaction in naturalistic study designs, in which there is potential that the administration of the side effects domain of the TSQM would interfere with routine clinical care.

22.  Structural and Predictive Equivalency of the Wisconsin Smoking Withdrawal Scale across Three Racial/Ethnic Groups 
Nicotine & Tobacco Research  2011;13(7):548-555.
The Wisconsin Smoking Withdrawal Scale (WSWS) is a valid and reliable scale among non-Latino Whites but has not been validated for use among other racial/ethnic groups despite increasing use with these populations. The current study examined the structural invariance and predictive equivalency of the WSWS across three racial/ethnic groups.
The WSWS scores of 424 African American, Latino, and White smokers receiving smoking cessation treatment were analyzed in a series of factor analyses and multiple-group analyses. Additionally, hierarchical logistic regression analyses were conducted to determine whether WSWS scores differentially predicted smoking relapse across racial/ethnic groups. These analyses were consistent with a step-down hierarchical regression procedure for examination of test bias.
The 7-factor structure of the WSWS was largely confirmed in the current study, with the exception of the removal of two offending items. Evidence of full invariance across race/ethnicity was found in multiple-group analyses. The WSWS total score and subscales measuring anger, anxiety, concentration, and sadness predicted relapse, whereas the hunger, craving, and sleep subscales did not. None of these scales displayed differential predictive ability across race/ethnicity. The WSWS sleep subscale showed a significant interaction with race/ethnicity such that it was a significant predictor of relapse among Whites but not African Americans or Latinos.
Overall, the WSWS is similar in structure and predictive of relapse across racial/ethnic groups. Caution should be exercised when using the WSWS sleep subscale with African Americans and Latinos.

23.  Validity of the SF-12 for Use in a Low-Income African American Community-Based Research Initiative (REACH 2010) 
Preventing Chronic Disease  2008;5(2):A44.
The objective of our study was to assess the psychometric properties of the Medical Outcomes Study's 12-Item Short Form Survey Instrument (SF-12) for use in a low-income African American community. The SF-12, a commonly used functional health status assessment, was developed based on responses of an ethnically homogeneous sample of whites. Our assessment addressed the appropriateness of the instrument for establishing baseline indicators for mental and physical health status as part of Nashville, Tennessee's, Racial and Ethnic Approaches to Community Health (REACH) 2010 initiative, a community-based participatory research study.
A cross-sectional random residential sample of 1721 African Americans responded to a telephone survey that included the SF-12 survey items and other indicators of mental and physical health status. The SF-12 was assessed by examining item-level characteristics, estimates of scale reliability (internal consistency), and construct validity.
Construct validity assessed by the method of extreme groups determined that SF-12 summary scores varied for individuals who differed in self-reported medical conditions. Convergent and discriminate validity assessed by multitrait analysis yielded satisfactory coefficients. Concurrent validity was also shown to be satisfactory, assessed by correlating SF-12 summary scores with independent measures of physical and mental health status.
The SF-12 appears to be a valid measure for assessing health status of low-income African Americans.

24.  Assessments for measuring patient-centered cultural sensitivity in community-based primary care clinics. 
OBJECTIVE: To develop and test the reliability of three race/ethnicity-specific forms of the pilot Tucker-Culturally Sensitive Health Care Inventory (T-CUSHCI) for use by patients at community-based primary care centers to evaluate the level of patient-centered cultural sensitivity perceived in the health care that they experience. METHODS: This research involved two studies using independent samples of primary care patients. In study 1, mostly low-income African-American, Hispanic and non-Hispanic white American patients (N=221) rated the importance of specific provider and office staff behaviors and attitudes, and center policies and physical environment characteristics that were earlier identified in previous focus groups as characteristics of patient-centered culturally sensitive healthcare. In study 2, three pilot race/ethnicity-specific T-CUSHCI patient forms were constructed from the items rated as at least important in study 1. Mostly low-income African-American and non-Hispanic white American patients (N=180) provided data to determine the reliability of the T-CUSHCI patient form for their racial/ethnic group. RESULTS: The pilot T-CUSHCI-African-American patient form and the pilot T-CUSHCI-non-Hispanic white American patient form were found to have Cronbach's alpha coefficients ranging from 0.71-0.96 and six-month test-retest and split-half reliabilities ranging from 0.92-0.99. CONCLUSION: The pilot T-CUSHCI patient forms (one each for African Americans, Hispanics and non-Hispanic whites) should be further tested using a national sample of patients. In the interim, these inventory forms can be used as clinical tools to obtain patient feedback for providing "individualized" patient-centered culturally sensitive healthcare.

25.  Development and Validation of Questionnaires Exploring Health Care Professionals' Intention to Use Wiki-Based Reminders to Promote Best Practices in Trauma 
JMIR Research Protocols  2014;3(4):e50.
Little is known about factors influencing professionals’ use of wikis.
We developed and validated two questionnaires to assess health care professionals’ intention to use wiki-based reminders for the management of trauma patients.
We developed questionnaires for emergency physicians (EPs) and allied health professions (AHPs) based on the Theory of Planned Behavior and adapted them to the salient beliefs of each, identified in an earlier study. Items measured demographics and direct and indirect theoretical constructs. We piloted the questionnaires with 2 focus groups (5 EPs and 5 AHPs) to identify problems of wording and length. Based on feedback, we adjusted the wording and combined certain items. A new convenience sample of 25 EPs and 26 AHPs then performed a test-retest of the questionnaires at a 2-week interval. We assessed internal consistency using Cronbach alpha coefficients and temporal stability of items with an agreement intraclass correlation coefficient (ICC).
Five EPs and 5 AHPs (3 nurses, 1 respiratory therapist, and 1 pharmacist) formed 2 focus groups; 25 EPs and 26 AHPs (12 nurses, 7 respiratory therapists, and 7 pharmacists) completed the test and retest. The EP questionnaire test-retest scores for consistency (Cronbach alpha) and stability (ICC) were intention (test: Cronbach alpha=.94; retest: Cronbach alpha=.98; ICC=.89), attitude (.74, .72, .70), subjective norm (.79, .78, .75), perceived behavioral control (.67, .65, .66), attitudinal beliefs (.94, .86, .60), normative beliefs (.83, .87, .79), and control beliefs barriers (.58, .67, .78) and facilitators (.97, .85, .30). The AHP questionnaire scores for consistency and stability were: intention (test Cronbach alpha=.69, retest Cronbach alpha=.81, ICC=.48), attitude (.85, .87, .83), subjective norm (.47, .82, .62), perceived behavioral control (.55, .62, .60), attitudinal beliefs (.92, .91, .82), normative beliefs (.85, .90, .74), and control beliefs barriers (.58, .55, .66) and facilitators (.72, .94, –.05). To improve the psychometric properties of both questionnaires, we reformulated poorly consistent or unstable items.
Our new theory-based questionnaires to measure health care professionals’ intention to use wiki-based reminders have adequate validity and reliability for use in large surveys. In the long run, they can be used to develop a theory-based implementation intervention for a wiki promoting best practices in trauma care.
