Research suggests that exposure to mass media depicting the thin-ideal body may be linked to body image disturbance in women. This meta-analysis examined experimental and correlational studies testing the links between media exposure to women's body dissatisfaction, internalization of the thin ideal, and eating behaviors and beliefs with a sample…

This research synthesis verifies the effectiveness of the Picture Exchange Communication System (PECS) for improving the functional communication skills of individuals with autism spectrum disorders (ASD). The research synthesis was focused on the degree to which variations in PECS training are associated with variations in functional…

The study used meta-analysis techniques to examine the effectiveness of intervention strategies for children with cerebral palsy. An examination of existing literature on meta-analysis revealed that techniques are available to accommodate a wide variety of research designs and data. Next, the percentage of studies purporting to address an…

Conducted meta-analysis of 108 well-designed outcome studies using 4- through 18-year-old subjects to examine effectiveness of psychotherapy with children and adolescents. Overall, findings revealed significant, durable effects of treatment that differed somewhat with client age and treatment method but which were reliably greater than zero for…

The Meta-Analysis Effect Size Calculator provides the user with many different ways to calculate an effect size depending on the information available in the original research report. In addition, the program computes an unbiased estimate of effect size. (Author)

Evaluated the effectiveness of paradoxical interventions in psychotherapy, in a meta-analysis of 12 data sets. Found that paradoxical interventions were as effective as, but not more effective than, the typical treatment made except for one month after treatment termination and with more severe cases, when it showed relatively greater…

The paper explores the conceptual bases of the controversy over meta analysis and computes it with traditional research on four dimensions: (1) scientific rigor, (2) detecting small effects, (3) problems of oversimplification, and (4) potential policy impact. It is argued that choice of procedures should be determined by the specific purpose of a…

Examined generalizability of treatment studies by comparing solicited and nonsolicited patient groups treated or studied in clinical settings. Findings suggest it may be possible to generate comparable samples in terms of pretreatment symptomatology, however, data are too limited to permit conclusions regarding generalizability of treatment…

As meta-analytic studies have become essential in educational research, resampling methods have matured and are supported by an in-depth theoretical and applied literature base. The objective of this paper is to assist researchers in applying resampling methods to the results of meta-analysis. The rationale for resampling methods is reviewed, and…

The practical significance, usefulness, and generalizability of research have for years hinged on a finding of statistical significance. Voices of reform have called for the use of effect sizes, confidence intervals, and meta-analytic synthesis of research as a way to judge the practical significance and generalizability of a discovery. This paper…

States that argumentative explicitness is acknowledged as a normative ideal in the practice of argument. Addresses one facet of the question of whether argumentative explicitness inevitably sacrifices instrumental success, by offering a meta-analytic review of the persuasive effects associated with degree of articulation given to the advocate's…

The vote-counting method of research integration disregards sample size and important descriptive information. Meta-analysis allows for integration of vast amounts of information, standardizes measuring scales, and overcomes contradictory findings. Two objections to meta-analysis are inclusion of studies of poor quality and the issue of…

MetaDOS is a point-and-click PASCAL program for meta-analysis that provides a user-friendly, Windows-type interface for DOS systems. Its statistical procedures basically follow those developed by J. E. Hunter and F. L. Schmidt and their colleagues (1990 and 1993). (Author/SLD)

Conducted a meta analysis of studies of procedural modifications of the Angoff method of setting cutoff scores. Findings for 38 studies (113 judges) show that common modifications have produced systematic effects on cutoff scores and the degree of consensus among judges. (SLD)

Conducted a reliability generalizability study on the Coopersmith Self-Esteem Inventory (CSEI; S. Coopersmith, 1967) to examine the variability of reliability estimates across studies and to identify study characteristics that may predict this variability. Results show that reliability for CSEI scores can vary considerably, especially at the…
