Computer-based prevention of intimate partner violence in marriage

Area of Science:

• Psychology
• Public Health
• Sociology

Background:

• Intimate partner violence (IPV) presents a significant societal challenge with limited success in recidivism reduction.
• Primary prevention strategies are crucial for effectively decreasing the occurrence of IPV.

Purpose of the Study:

• To evaluate the impact of a computer-based preventive intervention, known as ePREP, on intimate partner violence within married couples.

Main Methods:

• A randomized clinical trial compared the ePREP intervention against an active placebo control group.
• Data were collected from 52 married couples using self and partner reports on the Revised Conflict Tactics Scale at baseline, 6 weeks, and 1 year.
• The Actor Partner Interdependence Model was utilized for dyadic data analysis.

Main Results:

• The ePREP intervention demonstrated a substantial reduction in physical aggression (90% decrease) and psychological aggression (0.18 SD reduction) among married couples.
• These positive outcomes were sustained at the one-year follow-up assessment.

Conclusions:

• Widely accessible and low-cost interventions enhance the potential to reach individuals most in need.
• The findings suggest implications for flexible intervention delivery and a shift in treatment approaches.
