Meta-Analysis on Interventions for Children Exposed to Intimate Partner Violence.

Area of Science:

• Child Psychology
• Intervention Science
• Public Health

Background:

• Intimate partner violence (IPV) exposure significantly impacts child emotional and behavioral development.
• Previous reviews on interventions for children exposed to IPV have yielded inconsistent findings.
• A comprehensive meta-analysis is needed to synthesize existing evidence on intervention effectiveness.

Purpose of the Study:

• To conduct a meta-analysis of child emotional and behavioral outcomes following interventions for intimate partner violence (IPV) exposure.
• To examine effect sizes and identify moderators influencing intervention outcomes.
• To provide evidence-based recommendations for improving intervention strategies.

Main Methods:

• Systematic search of 12 published reviews (2000-2019) including 21 evaluation studies with a child component.
• Inclusion criteria: quantitative pre- and post-intervention data, standardized instruments, and meta-analysis-compatible data.
• Meta-analysis of effect sizes, exploring moderators across studies.

Main Results:

• Overall medium effect size (d = 0.49) for pre- to post-intervention improvements in child outcomes.
• Internalizing behaviors showed sustained improvement at follow-up.
• Trauma-related, social, externalizing, and total behaviors showed decreased improvements at follow-up, though effect sizes remained significant (d = 0.36-0.44).
• Greater intervention effects were observed when treatment was not exclusively trauma-specific.

Conclusions:

• Intimate partner violence (IPV) exposure interventions are generally effective for improving children's emotional and behavioral well-being.
• Interventions benefit from greater tailoring to children's specific needs and incorporating diverse content areas (trauma-specific and non-trauma-specific).
• Enhancing the maintenance of treatment gains requires further focus.
