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…

Conducted a reliability generalization study on Zuckerman's Sensation Seeking Scale (M. Zuckerman and others, 1964) using 113 reliability coefficients from 21 published studies. The reliability of scores was marginal for four of the five scales, and low for the other. Mean age of subjects has a significant relationship with score reliability. (SLD)

Using meta analysis, examined the predictive validity of scores on the MacAndrew Alcoholism Scale (C. MacAndrew, 1965). Compared results for 161 studies with results for 63 studies using cut scores. Discusses why the use of continuous measures rather than cut scores is recommended. (SLD)

Meta-analytic techniques were used to summarize the statistical robustness literature on Type I error properties of alternatives to the one-way analysis of variance "F" test. The James (1951) and Welch (1951) tests performed best under violations of the variance homogeneity assumption, although their use is not always appropriate. (SLD)

Conducted meta-analysis of 37 studies dealing with long-term consequences of parental divorce for adult well-being. Results indicated adults who experienced parental divorce exhibited lower levels of well-being than did adults whose parent were continuously married. Strongest estimated effects occurred in areas of one-parent family status,…

Reviews literature concerning the quantitative synthesis of single-subject research. Discusses the general rationales, describes procedures for synthesizing, and reviews results of application of single-subject research procedures. Suggests that procedures based on percentage of overlapping data between baseline and treatment are justifiable and…
