Abstract Presents a meta-analytical review of 49 studies, from 1981 to 1990, on the effect of social competence training (SCT) on 3- to 15-year-olds. Main issues were (a) effectiveness in relation to program type and client characteristics as well as outcome criteria, (b) differential effects, (c) types of long-term effect, and (d) a comparison to other meta-analyses in the field, Results showed that SCT was moderately effective. However, effect sizes were lower than in previous studies. There were specific, characteristic effects for various types of program and on various client groups. Two main problems were identified: First, significant effect sizes were found only when direct goal criteria (e.g., social-cognitive skills) were evaluated, whereas there were few effects on broader constructs (e.g., social adjustment). Second, long-term effects were weak. We concluded that further primary studies are needed on the generalization and maintenance of change.
