Preventing prejudice and improving intergroup attitudes: A meta-analysis of child and adolescent training programs

Year Published:

Abstract

This article reports the results of a meta-analysis of 81 research reports containing 122 intervention-control comparisons of structured programs to reduce prejudice or promote positive intergroup attitudes in children and adolescents. Overall, the analysis revealed a mean effect size of d = 0.30, indicating low to moderate intervention effects. From the great variety of different approaches, interventions based on direct contact experiences along with social-cognitive training programs designed to promote empathy and perspective taking showed the strongest effect sizes. In addition, effects varied according to the program participant’s social status (higher effects for majority groups), the target out-group (lower effect sizes for ethnic vs. disabled and aged out-groups), and the type of outcome assessment (higher effects for cognitive vs. affective and behavioral measures of intergroup attitudes). The discussion considers several limitations including the lack of implementation and follow-up research as well as future direction of research on promoting intergroup relations.
