Meta-analysis of 155 research reports that used one of three commitment scales (affective, continuance, or normative) found strong correlations between the scales and correlates of jobs satisfaction, job involvement, and organizational commitment. All three were negatively related to withdrawal and turnover. Perceived organizational support had…

A meta-analysis was conducted of 60 empirical samples (n=39.154), 53 of which used parallel measures of self-efficacy and interests. Results demonstrated that self-efficacy and interests are independent and correlate moderately. Overlap varies considerably for Social, Enterprising, and Conventional interest domains depending on the measure used.…

Introduces statistical and procedural methods of meta-analysis, and explains how to interpret the findings of meta-analytic studies currently appearing throughout the social science literature. Includes overview of meta-analysis and discussion of seven steps used in conducting a meta-analysis. (Author/NB)

Reviewed validity evidence for systematic methods of evaluating training and experience (T&E) ratings in personnel selection. Meta-analytic summaries of data indicated that validity varied with type of T&E procedure used. Illinois job element and behavioral consistency methods demonstrated useful levels of validity with small corrected standard…

Used meta-analysis to examine duration of group experience and structure provided by leader in counseling groups from 26 studies. Group composition appeared to have greatest effect in unstructured group which was relatively long in duration. Leaders using short-term, structured groups may be less concerned with composition, as its potential effect…

Analyzes manuscripts that have studied the treatment of communication apprehension. Concludes that all forms of treatment (cognitive modification, systematic desensitization, and skills training) were effective in reducing public speaking anxiety and that the type of self-report scale did not affect the observed effect size. (MS)

META-RAND, a Statistical Analysis System macro that generates random values used for calculating correlations in a meta analysis, is described. Output consists of uncorrected and corrected mean and variances of "r" and several measures of the degree of homogeneity or heterogeneity in the data. (SLD)

Conducted meta-analysis of 14 studies to determine gender differences in caregiving stressors and burden. Found essentially no significant gender differences in functional impairment of frail care recipient or total caregiver involvement in care or in money management tasks. Female caregivers were more likely to carry out personal care and…

Meta analysis of 22 studies testing 1,598 subjects revealed that aging has a great effect on intentional memory for spatial location. However, methodological limits were found: fewer than half of the studies controlled for age differences in visual acuity or did not use a test phase of fixed duration. (SK)

Describes a meta-analysis comparing the persuasiveness of one-sided and two-sided messages. Demonstrates that a two-sided message with refutation is more persuasive than a one-sided message, whereas a one-sided message is more persuasive than a two-sided message without refutation. (SR)

Metaanalysis of 15 studies revealed a moderately strong, positive as sociation between commitment to a profession and to an organization. Degree of professionalization, job position, and form of professional commitment moderated the correlation between professional and organizational commitment. (SK)

Tested meta-analytically the hypotheses that self-efficacy beliefs relate positively to academic performance and persistence. Results revealed positive and statistically significant relationships between self-efficacy beliefs and academic performance and persistence outcomes across wide variety of subjects, experimental designs, and assessments…

Correlations between centralization and effectiveness were obtained from 26 independent samples in the organization science literature. Hypotheses were developed and statistically tested. The hypotheses that were supported are reflected in a final theory of the centralization-effectiveness relationship. (75 references) (MLF)

Performed meta-analyses on nine studies of subjects' (n=434) penile responsivity to rape stimuli. Mean effect size for raw score data suggested that most sexual aggressors against women exhibit slightly more rape arousal than control or comparison subjects, whereas mean effect size for rape index (rape arousal:consenting sexual arousal) data…

Develops the argument that estimates of the moderator effect may vary depending on the approach (regression or subgroup) taken by the meta-analyst. The difference results from ambiguity in assigning the variance shared by correlated moderators when the shared variance is also shared with the effect size. Illustrative tables are presented. (SLD)
