Abstract
This meta-analysis focuses on the efficacy of interventions for adults facing separation or divorce designed to help them through the process of divorce. In this meta-analysis we investigate the nature of these programmes and their influence on reduction of divorce-related symptoms. Using a heterogeneous data-set (amount of variance explained by sampling error 58.68%) of N = 2022 adults, 24 independent effect sizes were calculated. The overall mean effect size was= 0.47. Due to the heterogeneity of the results, partial analyses were also conducted. Our results on study characteristics and effect sizes as well as standards for presenting results in primary studies are discussed. Altogether, this meta-analysis provides a detailed and methodologically valid contribution to quantitative research in the field of divorce adjustment.
