Presents a methodological critique of the 1998 meta-analysis of child sexual abuse outcomes by Rind et al. By restricting a supposedly broad meta-analysis to only some of the population in question, the conclusions they drew regarding this complex topic, primarily that adult-child sex is not necessarily harmful, are invalid. (Contains 33…

Presents a review of all types of child sexual abuse research ignored by Rind, Tromovitch, and Bauserman in their 1998 meta-analytic study. Eight major findings are addressed. Altogether these findings demonstrate the narrow focus of the meta-analysis. By restricting a broad meta-analysis to only some of the research and population in question,…

The meta-analytic method proposed by S. W. Raudenbush (1988) for studying variance heterogeneity was studied. Results of a Monte Carlo study indicate that the Type I error rate of the test is sensitive to even modestly platykurtic score distributions and to the ratio of study sample size to the number of studies.

Review of 1,791 cases from 8 studies of college business students' learning styles revealed small to moderate effect sizes in style preferences. Kolb's learning styles were not evenly distributed and there was much diversity among business students and within specific majors. (Contains 22 references.) (SK)

Studies (N=25) of the effectiveness of Direct Instruction programs with special education students were examined in a meta-analysis comparison. None of the studies showed results favoring comparison groups. Fifty-three percent of the outcomes significantly favored Direct Instruction. Effects were not restricted to particular handicapping…

The critical analysis of 23 studies using respondent techniques for the reduction of excessive emotional reactions in school children focuses on research design, dependent variables, independent variables, component analysis, and demonstrations of generalization and maintenance. Results indicate widespread methodological flaws that limit the…

A grounded meta-analytic technique for comparing organizational interventions derived from rational-based strategies (e.g., management-by-objectives, planned change) with organizational culture-based strategies (organizational culture, climate) is described. The method is seen as useful for integrating qualitative and quantitative research.…

Employed meta-analysis to determine existence of the detrimental effects of extrinsic rewards on intrinsic motivation. Results showed that within strictly defined parameters the phenomenon concerning the detrimental effects of reward described in Deci's Cognitive Evaluation Theory did exist. (Author/NB)

A critical analysis of 13 validation studies of the use of peer nomination forms to identify gifted students indicates methodological weaknesses. A four-step plan for research on the psychometric qualities of peer nomination forms is proposed. (Author/DB)

Meta analysis of 273 investigations concerned with the modification of attitudes toward persons with disabilities revealed equivocal results possibly due to methodological deficiencies (study quality ratings were low) or to the complexity of human attitudes. (Author/DB)

Examines by meta-analysis the effect that exposure to pornography produces on aggressive behavior under laboratory conditions considering a variety of possible moderating conditions. Demonstrates a homogeneous set of results showing that pictorial nudity reduces subsequent violent behavior, but that depictions of nonviolent sexual behavior and…

When the process of publication favors studies with small p-values and large effect estimates, combined estimates from many studies may be biased. This paper describes a model for estimation of effect size when there is selection based on one-tailed p-values. (SLD)

A Monte Carlo study considers the use of meta analysis with the Solomon four-group design. Experiment-wise Type I error properties and the relative power properties of Stouffer's Z in the Solomon four-group design are explored. Obstacles to conducting meta analysis in the Solomon design are discussed. (SLD)

Problems and illustrations are presented from a meta-analysis of crime reduction programs. Eight criteria are specified for including studies in a meta-analysis, and some problematic studies are discussed using the criteria. Rules for handling problem studies in order to retain consistency throughout the analysis are discussed. (SLD)

Conducted meta-analysis on 67 studies of impact of career education on academic achievement in elementary and secondary schools. Found evidence of small positive effect, with career education interventions improving student academic achievement levels an average of 0.16 standard deviations over alternative or control conditions. Results support…
