Meta-analysis of couple therapy: Effects across outcomes, designs, timeframes, and other moderators.

Couple therapy has large effects on key relationship domains and gains are generally maintained over short- and long-term follow-up with minimal impact of tested moderators. Limitations include sample of exclusively opposite sex couples and inability to fully model dependencies within studies. The relationship between mean gain effect sizes and between-groups comparisons is discussed with implications for future research. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
