ENRICHMENT OUTCOME RESEARCH:A META-ANALYSIS OF PREMARITAL, MARITAL AND FAMILY INTERVENTIONS

The findings from a meta-analysis of 85 studies of premarital, marital, and family enrichment, representing 3,886 couples or families are presented. Metaanalysis is a method for statistically aggregating and evaluating empirical findings. Findings from the study are discussed in terms of overall enrichment effectiveness as well as salient program, subject, design, measurement, and analysis characteristics. The enrichment studies yielded an average effect size of .44, which indicates that the average person who participates in enrichment is better off following intervention than 67% of those who do not. The most powerful factors related to outcome were measurement variables rather than those related to program content, structure, leadership, or participant characteristics. Implications of these findings are discussed.
