The COSMIN checklist is a standardized tool for assessing the methodological quality of studies on measurement properties. It contains 9 boxes, each dealing with one measurement property, with 5–18 items per box about design aspects and statistical methods. Our aim was to develop a scoring system for the COSMIN checklist to calculate quality scores per measurement property when using the checklist in systematic reviews of measurement properties.
The scoring system was developed based on discussions among experts and testing of the scoring system on 46 articles from a systematic review. Four response options were defined for each COSMIN item (excellent, good, fair, and poor). A quality score per measurement property is obtained by taking the lowest rating of any item in a box (“worst score counts”).
Specific criteria for excellent, good, fair, and poor quality for each COSMIN item are described. In defining the criteria, the “worst score counts” algorithm was taken into consideration. This means that only fatal flaws were defined as poor quality. The scores of the 46 articles show how the scoring system can be used to provide an overview of the methodological quality of studies included in a systematic review of measurement properties.
Based on experience in testing this scoring system on 46 articles, the COSMIN checklist with the proposed scoring system seems to be a useful tool for assessing the methodological quality of studies included in systematic reviews of measurement properties.

Introduction. Questionnaires on Functional Health Status (FHS) are part of the assessment of oropharyngeal dysphagia. Objective. To conduct a systematic review of the literature on the psychometric properties of English-language FHS questionnaires in adults with oropharyngeal dysphagia. Methods. A systematic search was performed using the electronic databases Pubmed and Embase. The psychometric properties of the questionnaires were determined based on the COSMIN taxonomy of measurement properties and definitions for health-related patient-reported outcomes and the COSMIN checklist using preset psychometric criteria. Results. Three questionnaires were included: the Eating Assessment Tool (EAT-10), the Swallowing Outcome after Laryngectomy (SOAL), and the Self-report Symptom Inventory. The Sydney Swallow Questionnaire (SSQ) proved to be identical to the Modified Self-report Symptom Inventory. All FHS questionnaires obtained poor overall methodological quality scores for most measurement properties. Conclusions. The retrieved FHS questionnaires need psychometric reevaluation; if the overall methodological quality shows satisfactory improvement on most measurement properties, the use of the questionnaires in daily clinic and research can be justified. However, in case of insufficient validity and/or reliability scores, new FHS questionnaires need to be developed using and reporting on preestablished psychometric criteria as recommended in literature.
The growing body of data on prevalence of complementary and alternative medicine (CAM) usage means there is a need to standardize measurement on an international level. An international team has published a questionnaire (I-CAM-Q), but no validation has yet been provided. The aim of the present study was to provide a German measurement instrument for CAM usage (I-CAM-G) which closely resembles the original English version, and to assess it’s performance in two potential samples for measuring CAM usage.
The English I-CAM-Q questionnaire was translated into German, and adapted slightly. The resulting I-CAM-G questionnaire was then pre-tested on 16 healthy volunteers, and 12 cognitive interviews were carried out. The questionnaire was employed in a sample of breast cancer patients (N = 92, paper and pencil), and a sample from the general population (N = 210, internet survey). Descriptive analyses of items and missing data, as well as results from the cognitive interviews, are presented in this paper.
The translated questionnaire had to be adapted to be consistent with the German health care system. All items were comprehensible, whereby some items were unambiguous (e.g. CAM use yes/no, helpfulness), while others gave rise to ambiguous answers (e.g. reasons for CAM use), or high rates of missing data (e.g. number of times the CAM modality had been used during the last 3 months). 78% of the breast cancer patients and up to 85% of a sample of the general population had used some form of CAM.
Following methodologically sound and comprehensive translation, adaptation and assessment processes using recognized translation procedures, cognitive interviews, and studying the performance of the questionnaire in two samples, we arrived at a German questionnaire for measuring CAM use which is comparable with the international (English) version. The questionnaire appropriately measures CAM use, with some items being more appropriate than others. We recommend the development of a short version.
The use of complementary and alternative medicine (CAM), a group of health care practices and products that are not considered part of conventional medicine, has increased in recent years, particularly among individuals with human immune deficiency virus (HIV). Assessing the prevalence and predictors of CAM use among HIV-positive populations is important because some CAM therapies may adversely affect the efficacy of conventional HIV medications. Unfortunately, CAM use is not comprehensively or systematically assessed among HIV-positive populations. Therefore, the aim of the present study was to evaluate the quality of the instruments employed in observational studies assessing CAM use among HIV-positive populations by examining the degree to which these studies (1) evaluated the psychometric properties of their CAM instruments and (2) assessed the multidimensional nature of CAM use.
A systematic review of studies was undertaken and specific review criteria were used to guide the inclusion of studies. Specifically, articles were included that were published in English and in a peer-reviewed journal between 1997 and 2007, recruited HIV-positive study participants, and assessed CAM use. Thirty-two (32) studies met these inclusion criteria.
Results suggest that CAM assessment among HIV-positive populations continues to be problematic. For example, approximately 20% of the studies assessed the reliability and 3% assessed the validity of the CAM instrument employed.
CAM assessment—regardless of the specific study population—is a complex and challenging task. However, CAM instruments will not become more refined over time in the absence of rigorous psychometric evaluation. Future research must assess reliability and validity and report these data in a clear and nuanced manner.
To critically appraise, compare and summarize the measurement properties of self-report fatigue questionnaires validated in patients with multiple sclerosis (MS), Parkinson’s disease (PD) or stroke.
MEDLINE, EMBASE, PsycINFO, CINAHL and SPORTdiscus were searched. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used to assess the methodological quality of studies. A qualitative data synthesis was performed to rate the measurement properties for each questionnaire.
Thirty-eight studies out of 5,336 records met the inclusion criteria, evaluating 31 questionnaires. Moderate evidence was found for adequate internal consistency and structural validity of the Fatigue Scale for Motor and Cognitive functions (FSMC) and for adequate reliability and structural validity of the Unidimensional Fatigue Impact Scale (U-FIS) in MS.
We recommend the FSMC and U-FIS in MS. The Functional Assessment of Chronic Illness Therapy Fatigue subscale (FACIT-F) and Fatigue Severity Scale (FSS) show promise in PD, and the Profile of Mood States Fatigue subscale (POMS-F) for stroke. Future studies should focus on measurement error, responsiveness and interpretability. Studies should also put emphasis on providing input for the theoretical construct of fatigue, allowing the development of questionnaires that reflect generic and disease-specific symptoms of fatigue.

Several disease-specific questionnaires to measure pain and disability in patients with neck pain have been translated. However, a simple translation of the original version doesn't guarantee similar measurement properties. The objective of this study is to critically appraise the quality of the translation process, cross-cultural validation and the measurement properties of translated versions of neck-specific questionnaires.
Bibliographic databases were searched for articles concerning the translation or evaluation of the measurement properties of a translated version of a neck-specific questionnaire. The methodological quality of the selected studies and the results of the measurement properties were critically appraised and rated using the COSMIN checklist and criteria for measurement properties.
The search strategy resulted in a total of 3641 unique hits, of which 27 articles, evaluating 6 different questionnaires in 15 different languages, were included in this study. Generally the methodological quality of the translation process is poor and none of the included studies performed a cross-cultural adaptation. A substantial amount of information regarding the measurement properties of translated versions of the different neck-specific questionnaires is lacking. Moreover, the evidence for the quality of measurement properties of the translated versions is mostly limited or assessed in studies of poor methodological quality.
Until results from high quality studies are available, we advise to use the Catalan, Dutch, English, Iranian, Korean, Spanish and Turkish version of the NDI, the Chinese version of the NPQ, and the Finnish, German and Italian version of the NPDS. The Greek NDI needs cross-cultural validation and there is no methodologically sound information for the Swedish NDI. For all other languages we advise to translate the original version of the NDI.
Mind-body complementary and alternative medicine (CAM) modalities (e.g., relaxation or meditation) for symptom management have not been well studied in adolescents with inflammatory bowel disease (IBD). The purposes of this study were to: 1) determine the prevalence of 5 types of mind-body CAM use, and consideration of use for symptom management; 2) assess characteristics associated with regular mind-body CAM use; and 3) examine whether regular and/or considered mind-body CAM use are associated with health-related quality of life (HRQOL).
Sixty-seven adolescents with IBD ages 12-19 recruited from a children’s hospital completed a questionnaire on CAM use and the Pediatric Quality of Life Inventory. Logistic regression models were estimated for regular and considered CAM use.
Participants mean (SD) age was 15.5 (2.1) years; 37 (55%) were female; 53 (79%) were white; and 20 (30%) had moderate disease severity. Adolescents used prayer (62%), relaxation (40%), and imagery (21%) once/day to once/week for symptom management. In multivariable analyses, females were more likely to use relaxation (OR=4.38, 95% CI= 1.25-15.29, c statistic=.73). Younger adolescents were more likely to regularly use (OR=.63, 95% CI=.42-.95, c statistic=.72) or consider using (OR=.77, 95% CI=.59-1.00, c statistic=.64) meditation. Adolescents with more severe disease (OR=4.17, 95% CI=1.07-16.29, c statistic=.83) were more willing to consider using relaxation in the future. Adolescents with worse HRQOL were more willing to consider using prayer and meditation for future symptom management (P<.05).
Many adolescents with IBD either currently use or would consider using mind-body CAM for symptom management.

Little is known about reliability and validity of instruments measuring externalizing mental health problems in immigrant ethnic minority youths.
To provide an overview of studies on measurement properties of instruments measuring these problems in immigrant ethnic minority youths, their methodological quality and results.
A systematic review of the literature in MEDLINE, EMbase, PsycINFO and Cochrane Library was performed. Evaluation of methodological quality of studies found was done by using the ‘COSMIN-checklist’. Full text, original articles, published in English after 1990 were included. Articles had to concern the development or evaluation of the measurement properties of self-reported, parent-reported and/or teacher- or clinician-reported questionnaires assessing or screening externalizing mental health problems in immigrant ethnic minority youths. Specific results of analyses on (an) immigrant ethnic minority group had to be given.
Twenty-nine studies evaluating 18 instruments met our criteria. Most studies concerned instruments with known validity in Western populations, tested mainly in African Americans. Considering methodological quality, inequivalences between ethnicities were found, self-reports seemed to perform better, and administration of an instrument influenced reliability and validity.
It seems that the majority of instruments for assessing externalizing problems in immigrant ethnic minority youths is currently not sufficiently validated. Further evaluating existing instruments is crucial to accurately assess and interpreted externalizing problems in immigrant ethnic minority youths.
Existing studies on the use of complementary and alternative medicine (CAM) have produced diverse results regarding the types and prevalence of CAM use due, in part, to variations in the measurement of CAM modalities. A questionnaire that can be adapted for use in a variety of populations will improve CAM utilization measurement. The purposes of this article are to (1) articulate the need for such a common questionnaire; (2) describe the process of questionnaire development; (3) present a model questionnaire with core questions; and (4) suggest standard techniques for adapting the questionnaire to different languages and populations.
An international workshop sponsored by the National Research Center in Complementary and Alternative Medicine (NAFKAM) of the University of Tromsø, Norway, brought CAM researchers and practitioners together to design an international CAM questionnaire (I-CAM-Q). Existing questionnaires were critiqued, and working groups drafted content for a new questionnaire. A smaller working group completed, tested, and revised this self-administered questionnaire.
The questionnaire that was developed contains four sections concerned with visits to health care providers, complementary treatments received from physicians, use of herbal medicine and dietary supplements, and self-help practices. A priori–specified practitioners, therapies, supplements, and practices are included, as well as places for researcher-specified and respondent-specified additions. Core questions are designed to elicit frequency of use, purpose (treatment of acute or chronic conditions, and health maintenance), and satisfaction. A penultimate version underwent pretesting with “think-aloud” techniques to identify problems related to meaning and format. The final questionnaire is presented, with suggestions for testing and translating.
Once validated in English and non-English speaking populations, the I-CAM-Q will provide an opportunity for researchers to gather comparable data in studies conducted in different populations. Such data will increase knowledge about the epidemiology of CAM use and provide the foundation for evidence-based comparisons at an international level.
To systematically review the psychometric properties of outcome measures used in stroke self-management interventions (SMIs) to (1) inform researchers, clinicians and commissioners about the properties of the measures in use and (2) make recommendations for the future development of self-management measurement in stroke.
Electronic databases, government websites, generic internet search engines and hand searches of reference lists. Abstracts were selected against inclusion criteria and retrieved for appraisal and systematically scored, using the COSMIN checklist.
Thirteen studies of stroke self-management originating from six countries were identified. Forty-three different measures (mean 5.08/study, SD 2.19) were adopted to evaluate self-SMIs. No studies measured self-management as a discreet concept. Six (46%) studies included untested measures. Eleven (85%) studies included at least one measure without reported reliability and validity in stroke populations.
The use of outcome measures which are related, indirect or proxy indicators of self-management and that have questionable reliability and validity, contributes to an inability to sensitively evaluate the effectiveness of stroke self-SMIs. Further enquiry into how the concept of self-management in stroke operates, would help to clarify the nature and range of specific self-management activities to be targeted and aid the selection of existing appropriate measures or the development of new measures.
Implications for Rehabilitation
The evaluation of complex interventions such as self-management interventions is aided by clear outcome expectations and valid and reliable measurement.
This review demonstrates a lack of outcome measures that specifically measure self-management of stroke. A minority of outcome measures that were used as proxy indicators for SM fulfill some of the criteria for quality outlined in the COSMIN checklist.
Clinicians should select measures which appropriately reflect expected outcomes, giving due consideration to the theoretical underpinnings of the intervention. Further work is required to establish which measures currently in use, if any, accurately reflect stoke self-management.
In the meantime, researchers should seek to develop psychometrically sound measures of stroke self-management to assist effective evaluation of such interventions in stroke.

Use of complementary and alternative medicine (CAM) is prevalent among HIV+ individuals despite the success of antiretroviral treatments and limited evidence of CAM's safety and efficacy. To characterize the potential impact of CAM use on HIV care, we conducted a systematic review of 40 studies of CAM use among HIV+ people. The goals of this review are to: (a) describe the demographic, biomedical, psychosocial, and health behavior correlates of CAM use; (b) characterize patient-reported reasons for CAM use; and (c) identify methodological and conceptual limitations of the reviewed studies. Findings confirm that a high proportion of HIV+ individuals report CAM use (M = 60%). Overall, CAM use is more common among HIV+ individuals who are men who have sex with men (MSM), non-minority, better educated, and less impoverished. CAM use is also associated with greater HIV symptom severity and longer disease duration. HIV+ CAM users commonly report that they use CAM to prevent or alleviate HIV-related symptoms, reduce treatment side-effects, and improve quality of life. Findings regarding the association between CAM use, psychosocial adjustment, and adherence to conventional HIV medications are mixed. While the reviewed studies are instrumental in describing the characteristics of HIV+ CAM users, this literature lacks a conceptual framework to identify causal factors involved in the decision to use CAM or explain implications of CAM use for conventional HIV care. To address this concern, we propose the use of health behavior theory and discuss implications of review findings for HIV care providers.
The COSMIN checklist is a tool for evaluating the methodological quality of studies on measurement properties of health-related patient-reported outcomes. The aim of this study is to determine the inter-rater agreement and reliability of each item score of the COSMIN checklist (n = 114).
75 articles evaluating measurement properties were randomly selected from the bibliographic database compiled by the Patient-Reported Outcome Measurement Group, Oxford, UK. Raters were asked to assess the methodological quality of three articles, using the COSMIN checklist. In a one-way design, percentage agreement and intraclass kappa coefficients or quadratic-weighted kappa coefficients were calculated for each item.
88 raters participated. Of the 75 selected articles, 26 articles were rated by four to six participants, and 49 by two or three participants. Overall, percentage agreement was appropriate (68% was above 80% agreement), and the kappa coefficients for the COSMIN items were low (61% was below 0.40, 6% was above 0.75). Reasons for low inter-rater agreement were need for subjective judgement, and accustom to different standards, terminology and definitions.
Results indicated that raters often choose the same response option, but that it is difficult on item level to distinguish between articles. When using the COSMIN checklist in a systematic review, we recommend getting some training and experience, completing it by two independent raters, and reaching consensus on one final rating. Instructions for using the checklist are improved.
Complementary and Alternative Medicine (CAM) is widely used throughout the UK and the Western world. CAM is commonly used for children and the decision-making process to use CAM is affected by numerous factors. Most research on CAM use lacks a theoretical framework and is largely based on bivariate statistics. The aim of this review was to identify a conceptual model which could be used to explain the decision-making process in parental choice of CAM.
A systematic search of the literature was carried out. A two-stage selection process with predetermined inclusion/exclusion criteria identified studies using a theoretical framework depicting the interaction of psychological factors involved in the CAM decision process. Papers were critically appraised and findings summarised.
Twenty two studies using a theoretical model to predict CAM use were included in the final review; only one examined child use. Seven different models were identified. The most commonly used and successful model was Andersen's Sociobehavioural Model (SBM). Two papers proposed modifications to the SBM for CAM use. Six qualitative studies developed their own model.
The SBM modified for CAM use, which incorporates both psychological and pragmatic determinants, was identified as the best conceptual model of CAM use. This model provides a valuable framework for future research, and could be used to explain child CAM use. An understanding of the decision making process is crucial in promoting shared decision making between healthcare practitioners and parents and could inform service delivery, guidance and policy.
Complementary and alternative medicine (CAM) is widely used for the treatment of infertility. While the Middle East and North Africa region has been shown to house one of the fastest growing markets of CAM products in the world, research describing the use of CAM therapies among Middle-Eastern infertile patients is minimal. The aim of this study is to examine the prevalence, characteristics and determinants of CAM use among infertile patients in Lebanon.
A cross sectional survey design was used to carry out face-to-face interviews with 213 consecutive patients attending the Assisted Reproductive Unit at a major academic medical center in Beirut. The questionnaire comprised three sections: socio-demographic and lifestyle characteristics, infertility-related aspects and information on CAM use. The main outcome measure was the use of CAM modalities for infertility treatment. Determinants of CAM use were assessed through the logistic regression method.
Overall, 41% of interviewed patients reported using a CAM modality at least once for their infertility. There was a differential by gender in the most commonly used CAM therapies; where males mostly used functional foods (e.g. honey & nuts) (82.9%) while females mostly relied on spiritual healing/prayer (56.5%). Factors associated with CAM use were higher household income (OR: 0.305, 95% CI: 0.132–0.703) and sex, with females using less CAM than males (OR: 0.12, 95% CI: 0.051–0.278). The older patients were diagnosed with infertility, the lower the odds of CAM use (p for trend <0.05). Almost half of the participants (48%) were advised on CAM use by their friends, and only 13% reported CAM use to their physician.
The considerably high use of CAM modalities among Lebanese infertile patients, added to a poor CAM use disclosure to physicians, underscore the need to integrate CAM into the education and training of health professionals, as well as enhance infertile patients' awareness on safe use of CAM products.

Central to the development of a sound evidence base for Complementary and Alternative Medicine (CAM) interventions is the need for valid, reliable and relevant outcome measures to assess whether the interventions work. We assessed the specific needs for a database that would cover a wide range of outcomes measures for CAM research and considered a framework for such a database.
The study was a survey of CAM researchers, practitioners and students. An online questionnaire was emailed to the members of the Canadian Interdisciplinary Network for CAM Research (IN-CAM) and the CAM Education and Research Network of Alberta (CAMera). The majority of survey questions were open-ended and asked about outcome measures currently used, outcome measures' assessment criteria, sources of information, perceived barriers to finding outcome measures and outcome domains of importance. Descriptive quantitative analysis and qualitative content analysis were used.
One hundred and sixty-four completed surveys were received. Of these, 62 respondents reported using outcome measures in their CAM research and identified 92 different specific outcomes. The most important barriers were the fact that, for many health concepts, outcome measures do not yet exist, as well as issues related to accessibility of instruments. Important outcome domains identified included physical, psychological, social, spiritual, quality of life and holistic measures. Participants also mentioned the importance of individualized measures that assess unique patient-centered outcomes for each research participant, and measures to assess the context of healing and the process of healing.
We have developed a preliminary framework that includes all components of health-related outcomes. The framework provides a foundation for a larger, comprehensive collection of CAM outcomes. It fits very well in a whole systems perspective, which requires an expanded set of outcome measures, such as individualized and holistic measures, with attention to issues of process and context.
Limited information exists on how adolescents decide to use complementary/alternative medicine (CAM). There are also no instruments specific to CAM, for the young adult population, which makes it difficult to explore knowledge in this area. The purpose of this study was to develop and examine the psychometric properties of the CAM Questionnaire for Young Adults which measures young adults’ attitudes about CAM. Participants for this cross-sectional survey were selected from enrolled undergraduate students at an urban university. Factor analysis identified three subscales: 1) positive beliefs about CAM; 2) environmental influence; and 3) psychological comfort. The scale has good internal consistency (Cronbach’s alpha = 0.79) and shows beginning demonstration of validity. Its use in this sample revealed that young adults who are female and have used CAM in the past for preventing or treating illness have the most positive attitude towards CAM and the greatest likelihood for continued use. The implication that prevention may play a role in young adults’ attitudes about CAM is a potential focus for future research.

The use of Complementary and Alternative medicine (CAM) has increased over the past years. In Germany, many general practitioners (GPs) use CAM in their daily practice. However, little is known about possible differences of GPs using CAM compared to GPs not using CAM. The aim of the study was to explore differences in personal and practice characteristics, work load and job satisfaction of GPs depending on their use of and attitude towards CAM. Furthermore, predictors for CAM use should be explored.
A questionnaire was developed based on qualitatively derived data. In addition, a validated instrument assessing job satisfaction was included in the questionnaire, which was sent to 3000 randomly selected GPs in Germany.
1027 returned the questionnaire of which 737 indicated to use CAM in daily practice. We found that GPs using CAM are more female, younger and have a trend towards a healthier life style. Their practices have higher proportions of privately insured patients and are slightly better technically equipped with ultrasound. GPs with a positive attitude had significant better values within the job satisfaction scale and lower working hours per week compared to GPs with neutral/negative attitude. Significant predictors for CAM use were a positive attitude towards CAM, holding a special qualification in CAM, own CAM use and the availability of an ultrasound in practice.
The identified differences suggest that those GPs using and believing in CAM have a different medical orientation and approach which in turn may influence their job satisfaction. With this finding CAM use turns out to be a relevant factor regarding job satisfaction and, with this, may be a possible lever to counteract the growing dissatisfaction of GPs in Germany. This finding could also be important for designing strategies to promote the recruitment of young doctors to general practice.
The need for Complementary and Alternative Medicine (CAM) and holistic approaches in allopathic medical school curricula has been well articulated. Despite increased CAM instruction, feasible and validated instruments for measuring learner outcomes in this content area do not widely exist. In addition, baseline attitudes or beliefs of medical students towards CAM, and the factors that may have formed them, including use of CAM itself, remain unreported.
A 10-item measure (CHBQ – CAM Health Belief Questionnaire) was constructed and administered to three successive classes of medical students simultaneously with the previously validated 29-item Integrative Medicine Attitude Questionnaire (IMAQ). Both measures were imbedded in a baseline needs assessment questionnaire. Demographic and other data were collected on students' use of CAM modalities and their awareness and use of primary CAM information resources. Analysis of CHBQ items was performed and its reliability and criterion-related validity were established.
Response rate was 96.5% (272 of 282 students studied). The shorter CHBQ compared favorably with the longer IMAQ in internal consistency reliability. Cronbach's coefficient alpha was 0.75 and 0.83 for the CHBQ and IMAQ respectively. Students showed positive attitudes/beliefs towards CAM and high levels of self-reported CAM use. The majority (73.5%) of students reported using at least one CAM modality, and 54% reported using at least two modalities. Eighty-one percent use the internet as a primary source of information for CAM.
The CHBQ is a practical, valid and reliable instrument for measuring medical student attitudes/beliefs and has potential utility for measuring the impact of CAM instruction. Medical students showed a high self-reported rate of CAM use and positive attitudes towards CAM. Short, didactic exposure to CAM instruction in the first year of medical school did not additionally impact these already positive attitudes. Unlike the IMAQ, which was intended for use with physicians, the CHBQ is generic in design and content and applicable to a variety of learner types. Evaluation measures must be appropriate for specific CAM instructional outcomes.
The objectives of this study were to explore the association between complementary and alternative medicine (CAM) use as reported by youth, and parents' and children's reported quality of life in youth with diabetes.
The study design was a cross-sectional survey.
Youth in Washington State participated in the SEARCH for Diabetes in Youth study, a national, multisite epidemiological study designed to assess the prevalence and incidence of diabetes in U.S. youth. Surveys assessing CAM utilization were mailed in January and April 2006.
One thousand four hundred and thirty-nine (1439) youth were mailed a CAM survey. The final sample consisted of 467 youth with both CAM survey results and quality-of-life data.
Difference in mean scores on Pediatric Quality of Life Inventory (PedsQL) between CAM users and nonusers overall, and specific CAM therapies were the outcome measures.
Of the 1439 participants approached, 587 (40.8%) returned the CAM survey. In adjusted analyses, children reported any CAM use as associated with more barriers to treatment (difference in mean scores −3.48, 95% confidence interval [CI] −6.65, −0.31). Children following a CAM diet reported higher quality of life (PedsQL Core Total difference 4.01, 95% CI [0.10–7.91]; Core Psychosocial difference was 6.45, 95% CI [1.95 to 10.95]), but those using stress-reduction activities reported poorer quality of life (Diabetes Total difference −4.19, 95% CI [−8.35 to −0.04]). Parent-reported quality of life was lower for children who used “other supplements” (Core Total difference −6.26, 95% CI [−11.29 to −1.24]; Core Psychosocial difference was −5.92, 95% CI [−11.65 to −0.19]).
CAM diets were associated with increased quality of life in youth with diabetes, whereas supplement use and stress-reduction activities were associated with decreased quality of life. The temporal sequence between CAM use and quality of life requires further study.
The safety and effectiveness of CAM interventions are of great relevance to pediatric health care providers. The objective of this study is to identify sources of reported randomized controlled trials (RCTs) in the field of pediatric complementary and alternative medicine (CAM).
Reports of RCTs were identified by searching Medline and 12 additional bibliographic databases and by reviewing the reference lists of previously identified pediatric CAM systematic reviews.
We identified 908 reports of RCTs that included children under 18 and investigated a CAM therapy. Since 1965, there has been a steady growth in the number of these trials that are being published. The four journals that published the most reported RCTs are The American Journal of Clinical Nutrition, Pediatrics, Journal of Pediatrics, and Lancet. Medline, CAB Health, and Embase were the best database sources for identifying these studies; they indexed 93.2%, 58.4% and 42.2 % respectively of the journals publishing reports of pediatric CAM RCTs.
Those working or interested in the field of pediatric CAM should routinely search Medline, CAB Health and Embase for literature in the field. The four core journals identified above should be included in their collection.

A growing number of physicians study complementary and alternative medicine (CAM). Limited data are available on perspectives of physicians with dual training in conventional medicine and CAM, on issues of communication and collaboration with CAM practitioners (CAMPs). Questionnaires were administered to primary care physicians employed in the largest health maintenance organization (HMO) in Israel and to MD and non-MD CAM practitioners employed by a CAM-related agency of the same HMO. Data for statistical analysis were available from 333 primary care physicians (PCPs) and 241 CAM practitioners. Thirty-one of the 241 CAMPs were dual-trained physicians employed in a CAM-related agency as practitioners and/or triage-consultants. Dual trained physicians and CAMPs shared similar attitudes and supported, more so than PCPs, collaborative physician–CAM practitioner teamwork in clinical practice, medical education and research. Nevertheless, dual trained physicians supported a physician-dominant teamwork model (similar to the PCPs’ approach) in contrast to non-MD CAM practitioners who mainly supported a co-directed teamwork model. Compared to PCPs and non-MD CAM practitioners, dual trained physicians supported significantly more a medical/referral letter as the preferred means of doctor–CAM practitioner communication. Dual trained physicians have a unique outlook toward CAM integration and physician–practitioner collaboration, compared to non-MD CAM practitioners and PCPs. More studies are warranted to explore the role of dual trained physicians as mediators of integration.

To assess pediatricians' attitudes toward & practice of Complementary/Alternative Medicine (CAM) including their knowledge, experience, & referral patterns for CAM therapies.
An anonymous, self-report, 27-item questionnaire was mailed nationally to fellows of the American Academy of Pediatrics in July 2004.
648 of 3500 pediatricians' surveyed responded (18%).
The median age ranged from 46–59 yrs; 52% female, 81% Caucasian, 71% generalists, & 85% trained in the US. Over 96% of pediatricians' responding believed their patients were using CAM. Discussions of CAM use were initiated by the family (70%) & only 37% of pediatricians asked about CAM use as part of routine medical history. Majority (84%) said more CME courses should be offered on CAM and 71% said they would consider referring patients to CAM practitioners. Medical conditions referred for CAM included; chronic problems (headaches, pain management, asthma, backaches) (86%), diseases with no known cure (55.5%) or failure of conventional therapies (56%), behavioral problems (49%), & psychiatric disorders (47%). American born, US medical school graduates, general pediatricians, & pediatricians who ask/talk about CAM were most likely to believe their patients used CAM (P < 0.01).
Pediatricians' have a positive attitude towards CAM. Majority believe that their patients are using CAM, that asking about CAM should be part of routine medical history, would consider referring to a CAM practitioner and want more education on CAM.
Background and Aims:
Complementary alternative medicine (CAM) covers many types of treatments and procedures that are usually not included in conventional medicine and are used in addition to physician-prescribed drugs to “complement” treatment. Although liver disease is prevalent in Saudi Arabia, not much is known about CAM use among Saudi liver disease patients. Thus, this study aimed to assess the prevalence of CAM use in these patients and their attitudes toward it.
Materials and Methods:
Patients were recruited randomly from a tertiary care hepatology clinic at King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia from February 4 to March 20, 2012. A four-page questionnaire was used to interview patients.
Of all the 232 participants surveyed, 55.6% have used or are using CAM to treat their liver disease with 45.0% of CAM users stating that they believe it has a positive effect on their treatment. Honey was the most used CAM treatment among the participants (39.0%). Herb use was represented by 31.8% of all users, while 13.5% used bloodletting as a treatment. Cautery was the least used CAM method (3.4%). Nearly 76.6% of CAM users were satisfied with using alternative treatments to help control their disease. Nearly 69.4% of users and nonusers stated that they believe CAM treatments to have numerous beneficial effects. Nearly 60.5% of CAM users stated that their physician had no knowledge of their CAM use. Of the factors included in linear multivariate regression analysis (including: Age, gender, and family CAM use, among other socioeconomic factors) only family CAM use was considered a significant independent factor affecting participants CAM use (Beta = 0.582, 95% CI: 0.372-0.754, P = 0.0001).
More than half of the patients have reported CAM use. Overall, more than two-thirds of the entire sample believed that CAM treatments have numerous health benefits.

To examine the quality of reports of complementary and alternative medicine (CAM) systematic reviews in the pediatric population. We also examined whether there were differences in the quality of reports of a subset of CAM reviews compared to reviews using conventional interventions.
We assessed the quality of reports of 47 CAM systematic reviews and 19 reviews evaluating a conventional intervention. The quality of each report was assessed using a validated 10-point scale.
Authors were particularly good at reporting: eligibility criteria for including primary studies, combining the primary studies for quantitative analysis appropriately, and basing their conclusions on the data included in the review. Reviewers were weak in reporting: how they avoided bias in the selection of primary studies, and how they evaluated the validity of the primary studies. Overall the reports achieved 43% (median = 3) of their maximum possible total score. The overall quality of reporting was similar for CAM reviews and conventional therapy ones.
Evidence based health care continues to make important contributions to the well being of children. To ensure the pediatric community can maximize the potential use of these interventions, it is important to ensure that systematic reviews are conducted and reported at the highest possible quality. Such reviews will be of benefit to a broad spectrum of interested stakeholders.
Aim. To identify and systematically review the clinimetric properties of habitual physical activity (HPA) measures in young children with a motor disability. Method. Five databases were searched for measures of HPA including: children aged <6.0 years with a neuromuscular disorder, physical activity defined as “bodily movement produced by skeletal muscles causing caloric expenditure”, reported HPA as duration, frequency, intensity, mode or energy expenditure, and evaluated clinimetric properties. The quality of papers was assessed using the COSMIN-checklist. A targeted search of identified measures found additional studies of typically developing young children (TDC). Results. Seven papers assessing four activity monitors met inclusion criteria. Four studies were of good methodological quality. The Minimod had good ability to measure continuous walking but the demonstrated poor ability to measure steps during free-living activities. The Intelligent Device for Energy Expenditure and Activity and Ambulatory Monitoring Pod showed poor ability to measure activity during both continuous walking and free-living activities. The StepWatch showed good ability to measure steps during continuous walking in TDC. Interpretation. Studies assessing the clinimetric properties of measures of HPA in this population are urgently needed to allow assessment of the relationship between HPA and health outcomes in this group.
