Effects of behavioral marital therapy: a meta-analysis of randomized controlled trials.
This meta-analysis summarizes results from 30 randomized experiments that compare behavioral marital therapy with no-treatment control with distressed couples. Results showed that behavioral marital therapy is significantly more effective than no treatment (d=.585). Although behavioral marital therapy research studies tend to be conducted under conditions that are less clinically representative than other samples of studies, representativeness was not significantly related to outcome. However, evidence also suggested that publication bias may exist in this literature whereby small sample studies with small effects are systematically missing compared with other studies. This bias may inflate the effects of behavioral marital therapies reported in previous meta-analyses, though we also explore a number of alternative explanations for this small sample bias.
