This review of meta-analyses of outcome studies of adults receiving Computer-Based Health Education (CBHE) has two goals. The first is to provide an overview of the efficacy of CBHE interventions, and the second is to identify moderators of these effects. A systematic literature search resulted in 15 meta-analyses of 278 controlled outcome studies. The meta-analyses were analysed with regard to reported (overall) effect sizes, heterogeneity and interaction effects. The results indicate a positive relationship between CBHE interventions and improvements in health-related outcomes, with small overall effect sizes compared to non-computer-based interventions. The sustainability of the effects was observed for up to six months. Outcome moderators (31 variables) were studied in 12 meta-analyses and were clustered into three categories: intervention features (20 variables), participant characteristics (five variables) and study features (six variables). No relationship with effectiveness was found for four intervention features, theoretical background, use of internet and e-mail, intervention setting and self-monitoring; two participant features, age and gender; and one study feature, the type of analysis. Regarding the other 24 identified features, no consistent results were observed across meta-analyses. To enhance the effectiveness of CBHE interventions, moderators of effects should be studied as single constructs in high-quality study designs. http://www.journalofinterdisciplinarysciences.com/ https://www.linkedin.com/in/leontienvreeburg/
AIM: This article describes the results of a study into the psychometric properties of a questionnaire about student nurses' perceptions of mental health care. The questionnaire was constructed in 2008, but has not yet been tested in terms of construct validity and reliability. A validated questionnaire is essential as a standardized method of analyzing student nurses' perceptions of mental health care.METHOD: To investigate the construct validity, an exploratory factor analysis was performed. Reliability was determined by measuring the internal consistency of the questionnaire.RESULTS: A principal component analysis (PCA) yielded a two-factor solution. The first factor comprised 9 items referring to the views of student nurses on psychiatric patients; the second factor comprised 6 items referring to the views of the students about professional careers in mental health care.CONCLUSION: The factor analysis and questionnaire produced two easily interpretable factors covering the same categories as those identified in the literature as determinants of a student nurse's choice for or against a career in mental health care. The questionnaire's construct validity was rated as sufficient, its reliability as acceptable. The problem is the low explained variance (25.6%). The usefulness of the questionnaire is therefore questionable. The usefulness might be improved through the expansion of some of the categories by additional items. Relevant suggestions are made in this article.
