Religion and spirituality are important aspects of multicultural competency for therapists to consider given the religious culture in America. Researchers have found that more than 90% of Americans claim either a Protestant or Catholic religious affiliation (Keller, 2000), 40% of Americans attend religious services on a weekly basis, and more than…

Background: Attention deficit/hyperactivity disorder (ADHD) is one of the most prevalent and commonly studied forms of psychopathology in children and adolescents. Causal models of ADHD have long implicated dysfunction in fronto-striatal and frontal-parietal networks supporting executive function, a hypothesis that can now be examined…

The performance of methods for detecting publication bias in meta-analysis was evaluated using Monte Carlo methods. Four methods of bias detection were investigated: Begg's rank correlation, Egger's regression, funnel plot regression, and trim and fill. Five factors were included in the simulation design: number of primary studies in each…

A meta-analysis in the form of Brinley plots was conducted on the mean reaction times of Attention Deficit Hyperactivity Disorder (ADHD) and Control groups of children and adolescents on the Stroop Color and Word Test (SCWT). ADHD reaction times were regressed on Control group reaction times for 17 data sets (accessed from 13 published studies).…

Numerous studies show that happy individuals are successful across multiple life domains, including marriage, friendship, income, work performance, and health. The authors suggest a conceptual model to account for these findings, arguing that the happiness-success link exists not only because success makes people happy, but also because positive…

Serious sequelae of youth depression, plus recent concerns over medication safety, prompt growing interest in the effects of youth psychotherapy. In previous meta-analyses, effect sizes (ESs) have averaged 0.99, well above conventional standards for a large effect and well above mean ES for other conditions. The authors applied rigorous analytic…

One conceptualization of meta-analysis is that studies within the meta-analysis are sampled from populations with mean effect sizes that vary (random-effects models). The consequences of not applying such models and the comparison of different methods have been hotly debated. A Monte Carlo study compared the efficacy of Hedges and Vevea's…

Research concerning the treatment of sexual offenders has generally focused on the treatment of adult offenders. The effectiveness of treatments for male adolescent sexual offenders (N = 644) was assessed in a meta-analysis of 10 studies. Overall, the results were surprisingly encouraging, suggesting that treatments for male adolescent sexual…

Meta-analytic research of experiments conducted on the effects of native-language (L1) glosses on second-language (L2) reading comprehension have revealed a significant difference between groups of studies with traditional and computer-assisted L1 glosses. This means that learners provided with L1 glosses comprehend significantly more…

The evaluation of systematic review as part of the evidence-based or evidence-informed practice movement is a dominant theme in current debates in educational research. This article contributes to the debate by offering a personal, reflexive narrative on the process of doing systematic review, relating some of the arguments regarding the merits…

This article has three purposes: to explain the two different uses of power analysis that can be used in health education research; to examine the extent to which power analysis is being used in published health education research; and to explain the implications of not using power analysis in research studies. Articles in seven leading health…

We reviewed nine studies in which children's cortisol levels at center daycare were assessed. Our first hypothesis, concerning intraindividual differences in cortisol levels across home and daycare settings, was also tested in a meta-analysis. Our main finding was that at daycare children display higher cortisol levels compared to the home…

Extended the findings from previous meta-analytic work by comparing the effectiveness of behavioral parent-training (BPT) and cognitive-behavioral therapy (CBT) for youth with antisocial behavior problems. Youth demographic variables were also examined as potential moderators of the effectiveness of these 2 types of interventions. Thirty BPT…

A review of the empirical research literature on Social Stories[TM] is presented, including a descriptive review and single-subject meta-analysis of appropriate studies. Examination of data suggests the effects of Social Stories[TM] are highly variable. Interpretations of extant studies are frequently confounded by inadequate participant…

Conceptual Foundations are the theoretical, conceptual, philosophical, and historical aspects; perspectives from outside the field; trends, issues, and future directions; and social, political, and economic facets that underlie our field. This paper attempted to capture these foundational aspects, taking stock of accomplishments and suggesting…
