We conducted a systematic literature review of anger management in people with intellectual disabilities (ID). We identified 2 studies that used randomized controlled trials and 6 that used pretest-posttest nonequivalent control group designs. The mean between-group effect size was 1.52 for randomized controlled trials and 0.89 for the other…

This review synthesized findings from 17 studies since 1998 regarding evaluation of outpatient treatments for adolescent substance abuse. These studies represented systematic design advances in adolescent clinical trial science. The research examined 46 different intervention conditions with a total sample of 2,307 adolescents. The sample included…

Relapse and recurrence following response to acute-phase treatment for major depressive disorder (MDD) are prevalent and costly. In a meta-analysis of 28 studies including 1,880 adults, the authors reviewed the world's published literature on cognitive-behavioral therapies (CT) aimed at preventing relapse-recurrence in MDD. Results indicate that…

In this article, the authors present a multilevel (or hierarchical linear) model that illustrates issues in the application of the model to data from meta-analytic studies. In doing so, several issues are discussed that typically arise in the course of a meta-analysis. These include the presence of non-zero between-study variability, how multiple…

The article reviews psychosocial treatments for phobic and anxiety disorders in youth. Using criteria from Nathan and Gorman (2002), 32 studies are evaluated along a continuum of methodological rigor. In addition, the treatments evaluated in each of the 32 studies are classified according to Chambless et al.'s (1996) and Chambless and Hollon's…

Reexamines the studies of K. S. Dobson regarding metaanalysis of cognitive-behavioral therapy for depression using the Beck Depression Inventory as an outcome measure. Confirms Dobson's conclusions but shows that about half the difference between CT and other treatments was predictable from researcher allegiance. Comparable analysis of a later set…

Evaluated the hypothesis that the apparent superiority of behavioral interventions among children is due to differences in the methodological quality of studies of behavioral and nonbehavioral treatments. Meta-analytic results found little support for this hypothesis. Because meta-analysis is a correlational technique, these results should be…

This article summarizes single-subject design intervention studies that include students with learning disabilities. Effect sizes of 85 studies were analyzed across instructional domains, sample characteristics, intervention parameters, and methodological procedures. Findings are supportive of the pervasive influence of cognitive strategy and…

Cognitive-behavior therapy (CBT) is based on the notion that thoughts, emotions, and actions are reciprocally linked and that changes in one of these necessarily will produce changes in the others. In CBT, thoughts, emotions, perceptions, and information processing styles all play a key role in the development and remediation of behavior and…
