Meta‐analysis of randomized, controlled treatment trials for pediatric obsessive‐compulsive disorder

Abstract: Objective: To conduct a meta-analysis on randomized, controlled treatment trials of pediatric obsessive-compulsive disorder (OCD). Method: Studies were included if they employed randomized, controlled methodology and treated young people (19 years or under) with OCD. A comprehensive literature search identified 13 RCTs containing 10 pharmacotherapy to control comparisons (N ¼ 1016) and five cognitive-behavioral therapy (CBT) to control comparisons (N ¼ 161). Results: Random effects modeling yielded statistically significant pooled effect size (ES) estimates for pharmacotherapy (ES ¼ .48, 95% CI ¼ .36 to .61, p < .00001) and CBT (ES ¼ 1.45, 95% CI ¼ .68 to 2.22, p ¼ .002). The results were robust to publication bias. Conclusions: This is the first meta-analysis of treatment RCTs for pediatric OCD. CBT and pharmacotherapy were the only treatments effective beyond control in alleviating OCD symptoms. CBT showed a greater ES than pharmacotherapy. Previous meta-analyses that included uncontrolled trials exaggerated the efficacy of both treatments. Keywords: Child/adolescent obsessive-compulsive disorder, pediatric, meta-analysis, cognitive-behavioral therapy, drug therapy, pharmacology, psychotherapy.

Personal and Psychosocial Predictors of Doping Use in Physical Activity Settings: A Meta-Analysis

Abstract: There is a growing body of empirical evidence on demographic and psychosocial predictors of doping intentions and behaviors utilizing a variety of variables and conceptual models. However, to date there has been no attempt to quantitatively synthesize the available evidence and identify the strongest predictors of doping. Using meta-analysis, we aimed to (i) determine effect sizes of psychological (e.g. attitudes) and social-contextual factors (e.g. social norms), and demographic (e.g. sex and age) variables on doping intentions and use; (ii) examine variables that moderate such effect sizes; and (iii) test a path analysis model, using the meta-analyzed effect sizes, based on variables from the theory of planned behavior (TPB). Articles were identified from online databases, by contacting experts in the field, and searching the World Anti-Doping Agency website. Studies that measured doping behaviors and/or doping intentions, and at least one other demographic, psychological, or social-contextual variable were included. We identified 63 independent datasets. Study information was extracted by using predefined data fields and taking into account study quality indicators. A random effects meta-analysis was carried out, correcting for sampling and measurement error, and identifying moderator variables. Path analysis was conducted on a subset of studies that utilized the TPB. Use of legal supplements, perceived social norms, and positive attitudes towards doping were the strongest positive correlates of doping intentions and behaviors. In contrast, morality and self-efficacy to refrain from doping had the strongest negative association with doping intentions and behaviors. Furthermore, path analysis suggested that attitudes, perceived norms, and self-efficacy to refrain from doping predicted intentions to dope and, indirectly, doping behaviors. Various meta-analyzed effect sizes were based on a small number of studies, which were correlational in nature. This is a limitation of the extant literature. This review identifies a number of important correlates of doping intention and behavior, many of which were measured via self-reports and were drawn from an extended TPB framework. Future research might benefit from embracing other conceptual models of doping behavior and adopting experimental methodologies that will test some of the identified correlates in an effort to develop targeted anti-doping policies and programs.

The roles of the formal and informal sectors in the provision of effective science education

Abstract: For many years, formal school science education has been criticised by students, teachers, parents and employers throughout the world. This article presents an argument that a greater collaboration between the formal and the informal sector could address some of these criticisms. The causes for concern about formal science education are summarised and the major approaches being taken to address them are outlined. The contributions that the informal sector currently makes to science education are identified. It is suggested that the provision of an effective science education entails an enhanced complementarity between the two sectors. Finally, there is a brief discussion of the collaboration and communication still needed if this is to be effective.

Do customer satisfaction and reputation mediate the CSR-FP link?: Evidence from Australia

Abstract: Direct tests between corporate social responsibility (CSR) and firm performance (FP) have been argued to be spurious. Following this line of argument, the present study tests a mediated model in understanding the CSR–FP relationship. Specifically, we posit that reputation and customer satisfaction mediate fully the CSR–FP relationship. Based on the results from a sample of 280 Australian firms, the findings suggest that CSR is linked with FP. However, the effect is indirect: while CSR is linked to both reputation and customer satisfaction, reputation alone mediates the CSR–FP relationship. The results are interesting, suggesting that to reduce ambiguity surrounding the CSR–FP relationship scholars need to significantly expand studies that address moderating and mediating variables. Discussion is given to these findings along with paths for future research.
