1.  Condoms “contain worms” and “cause HIV” in Tanzania: Negative Condom Beliefs Scale development and implications for HIV prevention 
Social science & medicine (1982)  2012;75(9):1685-1691.
Condom promotion remains a key component of HIV prevention programs, complimenting recent successes in biomedical HIV prevention. Although condom use has increased in much of East Africa, it remains substantially below optimal levels. Negative rumors about condoms have been documented in East Africa, yet the prevalence and effects of belief in the negative rumors have not been explored. This study evaluated levels of belief in negative rumors about condoms, developed a Negative Condom Beliefs Scale, and assessed its accuracy in predicting willingness to use condoms. A cross-sectional, cluster survey (n=370) was conducted representing adults in two rural districts in Northern Tanzania in 2008. Item agreement ranged from 35–53% for the following rumors regarding condoms: causing cancer, having holes, containing HIV, having worms, and the worms causing HIV. Items loaded on a single latent factor and had high internal consistency and convergent validity. In a multivariate model, negative condom score (AOR=0.67, 95% CI=0.6, 0.8) was the strongest single predictor of willingness to use condoms, followed by greater perceived anonymity in acquiring condoms (AOR=4.36, 95% CI=2.2, 8.6) and higher condom self-efficacy (AOR=4.24, 95% CI=2.0, 8.9). Our findings indicate high levels of subscription to negative beliefs about condoms, with two out of three respondents affirming belief in at least one negative condom rumor. This study highlights the relation between condom rumor beliefs and willingness to use condoms, and indicates avenues for future research and means for improving the design of HIV prevention programs.

2.  Excessive Drinking Among African American Men: Individual and Contextual Correlates 
In this paper we explored associations of multiple domains with regular drinking and getting drunk among adult African American men. Questionnaire-based, computer-assisted interviews were conducted with 484 men in Atlanta, Georgia. Data analysis involved multivariate logistic regression analyses. Findings show that being older increased the odds of both drinking behaviors. Sensation seeking increased the odds of regular drinking and having experienced childhood sexual and physical abuse increased the odds of getting drunk. Having health insurance reduced the odds of both outcomes. Insurance coverage and the heterogeneity among adult African American men must be considered in risk reduction efforts.

3.  Prevalence and predictors of complementary and alternative medicine use in African-Americans with acquired immune deficiency syndrome 
Background
The use of complementary and alternative medicine (CAM) among Human Immunodeficiency Virus (HIV)-positive individuals is becoming increasingly widespread. Unfortunately, some CAM therapies may jeopardize the efficacy of conventional HIV medication, making it critical to understand CAM use among this population.
Objective
To investigate the prevalence and predictors of CAM use in a theory-driven, multidimensional manner.
Methods
African-American individuals who had received a diagnosis of acquired immune deficiency syndrome (AIDS) were recruited. The computer-administered survey asked questions about participants’ CAM use and various psychosocial and socio-demographic characteristics. Participants’ most recent CD4+ cell counts and HIV RNA levels were abstracted from medical records. Linear regression analyses, adjusted for potential confounders, were conducted to assess the independent contribution of various factors in explaining frequency of CAM use.
Results
One hundred and eighty two subjects participated in the survey. Results indicate that most (94%) participants used at least one type of CAM therapy. The majority of participants (79.7%) used CAM therapies as a complement (rather than an alternative) to their HIV medications though half had not discussed these therapies with their healthcare providers. Female sex, high yearly income, high health literacy and high HIV RNA levels were associated with a greater frequency of CAM use, while stronger emotional well-being was associated with a lower frequency of CAM use.
Conclusions
The implications of these findings are discussed and suggestions for future research are provided.

4.  Recruiting Women for a Study on Perceived Risk of Cancer: Influence of Survey Topic Salience and Early Versus Late Response 
Introduction
Understanding the characteristics of early and late survey responders has implications for recruitment efforts and for informing potential response bias. The main objective of this analysis was to examine survey responder status (ie, early vs late response) by sociodemographic characteristics and by salience of study variables among respondents.
Methods
We analyzed data from a survey on family cancer history and perceived cancer risk among women at a large managed health-care organization. For baseline and 12-month follow-up surveys, we defined early versus late responder status according to the 95th percentile of the number of days it took to obtain completed interviews.
Results
We found no significant associations between responder status and sociodemographic characteristics at baseline or follow-up. At baseline, early responders were significantly more likely than late responders to have a personal history of breast cancer (5.2% vs 3.4%, P = .04) and to have been referred for genetic counseling (4.6% vs 2.0%, P = .004). The association between personal history of breast cancer and responder status persisted at follow-up; only 3.5% of late responders at baseline were also late responders at follow-up. Follow-up survey nonresponse rates did not vary by baseline responder status.
Conclusion
Survey topic salience is associated with early response and is important for recruitment. However, once recruited, late responders do not remain late responders at follow-up, suggesting that extra efforts made to recruit late responders are worthwhile. Health-related agencies that conduct surveys should consider survey salience in survey administration and recruitment strategies.

5.  Feasibility Study of Social Media to Reduce Intimate Partner Violence Among Gay Men in Metro Atlanta, Georgia 
Intimate Partner Violence (IPV) is a major public health issue occurring in the United States and globally. While little is known in general about IPV, understanding about the prevalence of physical IPV among gay men is even more obscure. There is a clear disparity in violence research attention focused on this vulnerable segment of society. This cross-sectional survey study was conducted to examine the feasibility of enrolling 100 gay men from Atlanta into an IPV survey study. The survey was administered via Facebook. Ninety-nine usable surveys were collected. Chi-square tests reveal that minority ethnic status, illicit drug use, and non-disclosed orientation status were all significantly associated with positive IPV reports--in terms of both victimization as well as perpetration. Overall, the majority of the study sample indicated that they believe IPV is a health problem in the Atlanta gay community. These findings bear importance for the Atlanta gay community and public health professionals who must address this nearly invisible yet increasing public health issue.

6.  Adherence, Sexual Risk, and Viral Load in HIV-Infected Women Prescribed Antiretroviral Therapy 
AIDS Patient Care and STDs  2011;25(7):431-438.
Abstract
The purpose of this study was to determine if there was a connection between adherence to antiretroviral therapy (ART) and use of risk reduction behaviors (RRB) in HIV-infected women who were prescribed antiretroviral therapy. The sample consisted of 193 predominately African American women with an average age of 44 who had been on ARV for approximately 9 years and had low annual incomes. All women were participating in a behavioral clinical trial focused on these dual outcomes. Using a risk index developed for this study, we examined the relationship of a composite of risk behaviors to electronically measured and self-reported adherence over the approximately 13-month study period. Women were categorized based on levels of adherence and risky behaviors, and we sought to determine if these classifications were associated with clinical outcomes of HIV viral load and CD4 counts. High levels of adherence were correlated with low risk behaviors (abstinence, consistent use of condoms, etc.). Those classified as high adherence and low-risk behavior (HALR) as well as those classified as high adherence and high-risk behavior (HAHR) had lower mean viral loads and higher CD4 counts than those in the other categories. Women in the low adherence and high-risk category (LAHR) had detectable viral loads and the lowest CD4 counts and are at higher risk for transmitting HIV to partners and unborn children. Our findings underscore the importance of addressing adherence to both ART and RRB in HIV clinical settings to improve clinical outcomes and reduce HIV transmission.

7.  Validity of Self-Reported Solar UVR Exposure Compared to Objectively Measured UVR Exposure 
Background
Reliance on verbal self-report of solar exposure in skin cancer prevention and epidemiologic studies may be problematic if self-report data are not valid due to systematic errors in recall, social desirability bias, or other reasons.
Methods
This study examines the validity of self-reports of exposure to ultraviolet radiation (UVR) compared to objectively measured exposure among children and adults in outdoor recreation settings in four regions of the United States. Objective UVR exposures of 515 participants were measured using polysulfone film badge UVR dosimeters on two days. The same subjects provided self-reported UVR exposure data on surveys and 4-day sun exposure diaries, for comparison to their objectively measured exposure.
Results
Dosimeter data showed that lifeguards had the greatest UVR exposure (24.5% of weekday ambient UVR), children the next highest exposures (10.3% ambient weekday UVR) and parents had the lowest (6.6% ambient weekday UVR). Similar patterns were observed in self-report data. Correlations between diary reports and dosimeter findings were fair to good and were highest for lifeguards (r = 0.38 – 0.57), followed by parents (r = 0.28 – 0.29) and children (r = 0.18 – 0.34). Correlations between survey and diary measures were moderate to good for lifeguards (r = 0.20 – 0.54) and children (r = 0.35 – 0.53).
Conclusions
This is the largest study of its kind to date, and supports the utility of self-report measures of solar UVR exposure.
Impact
Overall, self-reports of sun exposure produce valid measures of UVR exposure among parents, children, and lifeguards who work outdoors.

8.  Psychosocial Predictors of Lifestyle Management In Adults with Epilepsy 
Epilepsy & behavior : E&B  2008;13(3):523-528.
The purpose of this article is to describe a test of psychosocial variables predicting lifestyle management among people with epilepsy. The variables selected for the model were based on social cognitive theory and the results of previous studies examining psychosocial predictors of self-management among people with chronic physical health conditions. Variables included in the model were self-efficacy, outcome expectancies, depressive symptoms, and social support. Participants for the study were recruited from epilepsy treatment facilities in Boston, MA and Atlanta, GA. Half of the participants were female, 81% were white, and their mean age was 43.1 years. As predicted by social cognitive theory, self-efficacy was related to lifestyle management and explained 23% of its variation. Depressive symptoms were related to both self-efficacy and social support. Social support was related to self-efficacy. These findings suggest that lifestyle management is influenced by a number of relationships between psychosocial variables, particularly by self-efficacy.

9.  A Survey of Georgia Adult Protective Service Staff: Implications for Older Adult Injury Prevention and Policy 
Background:
The aging population is a rapidly growing demographic. Isolation and limited autonomy render many of the elderly vulnerable to abuse, neglect and exploitation. As the population grows, so does the need for Adult Protective Services (APS). This study was conducted to examine current knowledge of older adult protection laws in Georgia among APS staff and to identify training opportunities to better prepare the APS workforce in case detection and intervention.
Methods:
The Georgia State University Institute of Public Health faculty developed a primary survey in partnership with the Georgia Division of Aging Services’ leadership to identify key training priority issues for APS caseworkers and investigators. A 47-item electronic questionnaire was delivered to all APS employees via work-issued email accounts. We conducted descriptive analyses, t-tests and chi-square analyses to determine APS employees’ baseline knowledge of Georgia’s elder abuse policies, laws and practices, as well as examine associations of age, ethnicity, and educational attainment with knowledge. We used a p-value of 0.05 and 95% confidence intervals to determine statistical significance of analyses performed.
Result:
Ninety-two out of 175 APS staff responded to the survey (53% response rate). The majority of respondents were Caucasian (56%) women (92%). For over half the survey items, paired sample t-tests revealed significant differences between what APS staff reported as known and what APS staff members indicated they needed to know more about in terms of elder abuse and current policies. Chi-square tests revealed that non-Caucasians significantly preferred video conferencing as a training format (44% compared to 18%), [χ2(1) = 7.102, p < .008], whereas Caucasians preferred asynchronous online learning formats (55% compared to 28%) [χ2(1) =5.951, p < .015].
Conclusion:
Results from this study provide the Georgia Division of Aging with insight into specific policy areas that are not well understood by APS staff. Soliciting input from intended trainees allows public health educators to tailor and improve training sessions. Trainee input may result in optimization of policy implementation, which may result in greater injury prevention and protection of older adults vulnerable to abuse, neglect and exploitation.

10.  Adherence to Antiretroviral Medication Regimens: A Test of a Psychosocial Model 
AIDS and behavior  2007;13(1):10-22.
Objective
The primary aim of this study was to test a psychosocial model of medication adherence among people taking antiretroviral medications. This model was based primarily on social cognitive theory and included personal (self-efficacy, outcome expectancy, stigma, depression, and spirituality), social (social support, difficult life circumstances), and provider (patient satisfaction and decision-making) variables.
Design
The data for this analysis were obtained from the parent study, which was a randomized controlled trial (Get Busy Living) designed to evaluate an intervention to foster medication adherence. Factor analysis was used to develop the constructs for the model, and structural equation modeling was used to test the model. Only baseline data were used in this cross sectional analysis.
Methods
Participants were recruited from a HIV/AIDS clinic in Atlanta, GA. Prior to group assignment, participants were asked to complete a questionnaire that included assessment of the study variables.
Results
A total of 236 participants were included in the analysis. The mean age of the participants was 41 years; the majority were male, and most were African-American. In the final model, self-efficacy and depression demonstrated direct associations with adherence; whereas stigma, patient satisfaction, and social support were indirectly related to adherence through their association with either self-efficacy or depression.
Conclusion
These findings provide evidence to reinforce the belief that medication-taking behaviors are affected by a complex set of interactions among psychosocial variables and provide direction for adherence interventions.

11.  Development and Evaluation of a Complementary and Alternative Medicine Use Survey in African-Americans with Acquired Immune Deficiency Syndrome 
Abstract
Objectives
The purpose of the current study was to develop and evaluate the psychometric properties of a culturally- and stage-of-disease-appropriate measure of complementary and alternative medicine (CAM) use among a population of African-American individuals with acquired immune deficiency syndrome (AIDS) using a mixed-method design.
Design
Data were collected in two phases. In phase 1, qualitative data were used to refine an existing CAM measure for the specific study population in the present study. In phase 2, this refined instrument was implemented in a larger sample. The resulting numeric data were analyzed to evaluate the psychometric properties of the revised CAM instrument.
Setting
Data were collected from patients who were receiving care from the infectious disease clinic of a large, public, urban hospital in the Southeastern United States.
Subjects
Patients were eligible to participate if they (1) were receiving their care from the clinic, (2) had an AIDS diagnosis, (3) were identified as African-American, (4) were ≥21 years of age, (5) spoke English, and (6) were not cognitively impaired.
Measures
Focus groups in phase 1 were conducted with a semistructured focus group guide. Participants also completed a basic sociodemographic survey. Phase 2 participants used programmed laptops to answer questions about their CAM use and several sociodemographic questions.
Results
Information from the focus groups prompted some substantive revisions in the already-existing CAM survey. The revised instrument had satisfactory face validity and adequate test–retest reliability (r = 0.79). Furthermore, the instrument factored in a manner that was interpretable and consistent with prior findings.
Conclusions
In order for human immunodeficiency virus health care providers to provide the best care to their patients, they need to be informed about the types and frequency of CAM use among their patients. This can be accomplished by methodologically developing CAM instruments, rigorously implementing and assessing these instruments, and then disseminating the findings to researchers and practitioners.

12.  An Examination of the Psychometric Properties of the Antiretroviral General Adherence Scale (AGAS) in Two Samples of HIV-Infected Individuals 
This paper reports on the development and psychometric properties of the Antiretroviral General Adherence Scale (AGAS) in 2 NIH-funded projects: the Get Busy Living Project, a behavioral clinical trial to promote consistent use of antiretroviral therapy (ART); and the KHARMA Project, which addressed issues of adherence and risk reduction behavior in women. AGAS assesses the ease and ability of participants to take ART according to a health care provider's recommendations. Data were analyzed from completed baseline assessments of the 2 studies. The AGAS was internally consistent in both samples. Content, construct, and criterion validity were established using factor analysis and correlations of total AGAS scores with 2 measures of adherence: electronic drug monitoring (EDM) and an Adult AIDS Clinical Trials Group (AACTG) adherence scale. Viral load, CD4 cell counts, and depression scores were also examined. Reliability and validity of the AGAS were supported in both samples.

13.  Serum vitamin D concentrations are related to depression in young adult US population: the Third National Health and Nutrition Examination Survey 
Background
Vitamin D receptors have been mapped throughout the brain suggesting a role for vitamin D in psychosomatic disorders. Results from previous epidemiological studies on relation between vitamin D status and depression are equivocal. Also, limited information is available relating vitamin D status with depression in young adult US population.
Methods
Data from the third National Health and Nutrition Examination Survey were used to assess association between serum vitamin D and depression in 7970 non-institutionalized US residents, aged 15-39 y. Assessment of depression was done using the Diagnostic Interview Schedule developed by the National Institute of Mental Health. After accounting for several confounding variables in multivariate logistic regression analysis, we estimated odds ratios (OR) for having depression in vitamin D deficient persons in comparison to vitamin D sufficient persons.
Results
Women, non-Hispanic blacks, persons living below poverty, persons who did not consume supplements, persons living in South and West regions and in urban areas, persons with higher BMI, and persons with current depression had higher prevalence of vitamin D deficiency compared to their counterparts. OR for having current depressive episodes in persons with serum vitamin D ≤ 50 nmol/L is significantly higher relative to those with serum vitamin D ≥ 75 nmol/L (OR = 1.85; P = 0.021).
Conclusions
In this large population based study, likelihood of having depression in persons with vitamin D deficiency is significantly higher compared to those with vitamin D sufficiency. Early diagnosis and intervention are paramount because coexistence of vitamin D deficiency and depression has serious negative consequences on health.

14.  EFFECT OF A PSYCHOEDUCATIONAL INTERVENTION ON DEPRESSION, ANXIETY, and HEALTH RESOURCE USE IN ICD PATIENTS 
Background
Psychological responses have been reported for some patients after insertion of an implantable cardioverter defibrillator (ICD). This study tested the effects of a psychoeducational intervention on anxiety, depressive symptoms, functional status and health resource use during the first year after ICD implantation.
Methods
ICD patients (n=246) were randomized to usual care (UC), group (GRP), or telephone counseling (TC) intervention that included education, symptom management, and coping skill training. Participants were 58 ± 11 years, 73% men, and 23% minorities. Anxiety (STAI), depressive symptoms (BDI-II), and functional status (DASI) were measured at baseline and after 1, 3, 6 & 12 months. Health resource use and disability days were tracked. Analyses were repeated-measures ANCOVA to assess Group X Time effects, Chi-square for percentage with clinically significant anxiety and depression at each time point, and logistic regression.
Results
All groups experienced decreased anxiety and depressive symptoms over the 12 months; GRP intervention had lower STAI (p=.03) than UC at 3 months. Logistic regression revealed group differences for predicted probability of having depressive symptoms at 12 months (UC=.31, GRP=.17, TC=.13, p=.03). UC had greater calls to providers at 1 and 6 months (p<.05) and more sick/disability days at 12 months (p=.01) than intervention groups.
Conclusions
A psychoeducational intervention reduced anxiety and depressive symptoms early after ICD, lowered probability of depressive symptoms at one year, and decreased disability days/calls to providers. These findings support further study and clinical use of both group and telephone interventions to yield better psychological outcomes after ICD implant.

15.  Lifeguards’ Sun Protection Habits and Sunburns 
Archives of dermatology  2009;145(2):139-144.
Objective
To examine associations among outdoor pool environments, social norms, pool policies, and participation in a sun safety program with lifeguards’ sun protection habits and sunburn.
Design
Cross-sectional survey.
Setting
Outdoor swimming pools across the United States.
Participants
Lifeguards and aquatic instructors at pools participating in the Pool Cool skin cancer prevention program in 2001 (N=699) and 2002 (N=987).
Main Outcome Measures
Sun protection habits and number of sunburns.
Results
Social norms supporting sun safety were associated with more sun protection habits (95% confidence intervals [CIs], 0.18–0.28 in 2001 and 0.17–0.26 in 2002), as were pool policies supporting sun safety (95% CI, 0.02–0.07 in 2001 and 0.002–0.04 in 2002). There was a trend toward fewer sunburns as social norms, pool policies, and participation in the Pool Cool program increased, but results differed across the 2 years. In 2001, lower social norms scores and pool policy scores were associated with more reported sunburns. In 2002, teaching Pool Cool sun safety lessons was associated with fewer sunburns.
Conclusion
The pool environment is related to sun safety behaviors of outdoor pool staff, with social norms showing the strongest association.

16.  Children at Risk for Suicide Attempt and Attempt-related Injuries: Findings from the 2007 Youth Risk Behavior Survey 
Purpose:
The current study examines the associations between a range of risk factors and reports of suicide attempts and attempts requiring medical care in a nationally representative study of high school students. The goal is to examine sex differences in the risk factors associated with suicide attempts and attempt-related injuries requiring treatment by a health-care provider.
Methods:
We used data from the 2007 Youth Risk Behavior Survey for students in grades 9–12 to assess the prevalence and risk factors for suicidal behavior, as well as differences in these for boys and girls. Cross-sectional multivariate logistic regression analyses were computed to determine the most important risk factors for suicide attempts and for suicide attempts requiring medical care for the sample overall and also stratified for boys and for girls.
Results:
Overall, 6.9% of adolescents attempted suicide (9.3% of girls versus 4.6% of boys). Girls were more likely than boys to report a suicide attempt in the past year (Adj.OR=2.89). Among girls, sadness (Adj.OR=5.74), weapon carrying (Adj.OR=1.48), dating violence (Adj.OR=1.60), forced sex (Adj.OR=1.72), and huffing glue (Adj.OR=2.04) were significantly associated with suicide attempts. Among boys, sadness (Adj.OR=10.96), weapon carrying (Adj.OR=1.66), forced sex (Adj.OR=2.60), huffing glue (OR=1.63), hard drug use (Adj.OR=2.18), and sports involvement (Adj.OR=1.52) were significantly associated with suicide attempts.
Conclusion:
These findings demonstrate similarities and differences in the modifiable risk factors that increase risk for suicide attempts among boys and girls. In terms of the differences between boys and girls, hard drug use and sports involvement may be important factors for suicide-prevention strategies directed specifically towards boys, while dating violence victimization may be an important risk factor to address for girls. Overall, these findings can help guide prevention, clinical practice, and intervention strategies to prevent suicidal behaviors among adolescents.

17.  Development, Psychometric Testing, and Revision of the Atlanta Heart Failure Knowledge Test 
Background and Research Objective
Several heart failure (HF) knowledge tools have been developed and tested over the past decade; however, they vary in content, format, psychometric properties, and availability. This article details the development, psychometric testing, and revision of the Atlanta Heart Failure Knowledge Test (A-HFKT) as a standardized instrument for both the research and clinical settings.
Participants and Methods
Development and psychometric testing of the A-HFKT were undertaken with 116 New York Heart Association (NYHA) class II and III community-dwelling HF patients and their family members (FMs) participating in a family intervention study. Internal consistency, reliability, and content validity were examined. Construct validity was assessed by correlating education level, literacy, dietary sodium ingestion, medication adherence, and healthcare utilization with knowledge.
Results
Content validity ratings on relevance and clarity ranged from 0.55 to 1.0, with 81% of the items rated from 0.88 to 1.0. Cronbach α values were .84 for patients, .75 for FMs, and .73 for combined results. Construct validity testing revealed a small but significant correlation between higher patient and FM knowledge on sodium restriction questions and lower ingested sodium, r = −0.17, P = .05 and r = −0.19, P = .04, respectively, and between patient knowledge and number of days that medications were taken correctly (diuretics: r = 0.173, P < .05, and angiotensin-converting enzyme: r = 0.223, P = .01). Finally, patients seeking emergency care or requiring hospitalization in the 4 months before study entry were found to have significantly lower FM knowledge using both t test and logistic regression modeling.
Conclusions
The A-HFKT was revised using the content and construct validity data and is available for use with HF patients and FMs. The construct validity testing indicates that patient knowledge has a significant relationship to aspects of self-care. Furthermore, family knowledge may influence patient adherence with sodium restriction and healthcare utilization behavior.

18.  Validity of Self-Reported Sunscreen Use by Parents, Children, and Lifeguards 
Background
Verbal self-report is the method most often used to assess sunscreen use, but the data may be confounded by recall error and social desirability. Sunscreen swabbing is a non-invasive procedure to objectively assess the presence of sunscreen on the skin. This study examined the agreement between verbal reports of sunscreen use from survey and diary measures and objectively measured sunscreen use.
Methods
Participants were 564 parents, children aged 5–10 years, and lifeguards at 16 swimming pools in four regions of the U.S. Participants completed self-reported measures, including baseline and final surveys, as well as a 4-day diary and objective swabbing measures of sunscreen presence on 2 separate days. Data were collected in 2006 and analyzed in 2006–2007.
Results
Levels of sunscreen use were relatively high based on surveys (65.7%); diary data (40.3%); and swabbing measures (59.1%). Agreement between swabbing and diary measures of sunscreen use was fair to good, with κ statistics for children at 0.40, followed by lifeguards at 0.34 and parents at 0.27. Validity coefficients across measures of sunscreen use were higher for lifeguards and parents than for children, and diary measures were higher than surveys. No systematic errors were found across groups or by gender, latitude, study arm, or risk category.
Conclusions
These findings are comparable to those in other validation studies, including studies of the validity of dietary assessments. Self-reported estimates of sunscreen use by diaries or surveys appear to be as good as objective measures.

20.  WebEase: Development of a Web-Based Epilepsy Self-Management Intervention 
Preventing Chronic Disease  2008;6(1):A28.
People with epilepsy must adopt many self-management behaviors, especially regarding medication adherence, stress management, and sleep quality. In response to the need for theory-based self-management programs that people with epilepsy can easily access, the WebEase Web site was created and tested for feasibility, acceptability, and usability. This article discusses the theoretical background and developmental phases of WebEase and lessons learned throughout the development process. The WebEase research team developed content for the Web site on the basis of social cognitive theory, the transtheoretical model of behavior change, and motivational interviewing. Formative research and development of the WebEase program included a literature search, computer use survey, a focus group, and review by content experts and consumers.

21.  Implementation of Audio Computer-Assisted Interviewing Software in HIV/AIDS Research 
Computer assisted interviewing (CAI) has begun to play a more prominent role in HIV/AIDS prevention research. Despite the increased popularity of CAI, particularly audio computer assisted self-interviewing (ACASI), some research teams are still reluctant to implement ACASI technology due to lack of familiarity with the practical issues related to using these software packages. The purpose of this paper is to describe the implementation of one particular ACASI software package, the Questionnaire Development System™ (QDS™), in several nursing and HIV/AIDS prevention research settings. We present acceptability and satisfaction data from two large-scale public health studies in which we have used QDS with diverse populations. We also address issues related to developing and programming a questionnaire, discuss practical strategies related to planning for and implementing ACASI in the field, including selecting equipment, training staff, and collecting and transferring data, and summarize advantages and disadvantages of computer assisted research methods.
