Psychosocial interventions can significantly reduce symptoms of depression and PTSD in survivors of IPV, but the effects on IPV reexperience are not significant. High-intensive and integrative interventions have favorable effects, but long-term effects are unclear and the quality of evidence is low.
Survivors of intimate partner violence (IPV) face serious health-related, social and economic consequences. Prior meta-analyses indicate efficacy of psychosocial interventions for support of IPV survivors, but their results are affected by methodological limitations. Extensive subgroup analyses on the moderating effects of intervention and study characteristics are lacking. To address these limitations in an up-to-date and comprehensive meta-analytic review, four literature databases (PsycInfo, Medline, Embase, and CENTRAL, March 23, 2022) were searched for randomized-controlled trials examining the efficacy of psychosocial interventions compared to control groups in improving safety-related, mental health, and psychosocial outcomes in IPV survivors. Weighted effects on IPV, depression, posttraumatic stress disorder (PTSD), and psychosocial outcomes were calculated under random-effects assumption. Subgroup analyses were performed to investigate moderating effects of predefined intervention and study characteristics. Study quality was rated. In all, 80 studies were included in qualitative synthesis, and 40 studies in meta-analyses. Psychosocial interventions significantly reduced symptoms of depression (SMD: -0.15 [95% confidence interval, CI [-0.25, -0.04]; p = .006], I-2 = 54%) and PTSD (SMD: -0.15 [95% CI [-0.29, -0.01]; p = .04], I-2 = 52%), but not IPV reexperience (SMD: -0.02 [95% CI [ -0.09, 0.06]; p = .70], I-2 = 21%) compared to control conditions at post. High-intensive and integrative interventions, combining advocacy-based and psychological components, were favorable subgroups. Yielded effects were modest and not maintained long term. The quality of evidence was low and potential harms remain unclear. Future research should adopt higher standards of research conduct and reporting and must account for the complexity and diversity of IPV experiences.
