Effectiveness of Community-based Approach in Reducing the Intimate Partner Violence (IPV) Exposure and Outcome: A Randomised Controlled Trial of IPV Victimisation and Perpetration in Rwanda.

Background: Few studies have explored the effectiveness of the Community-Based Approach (CBA) on the reduction of intimate partner violence (IPV) exposure and its outcomes in Rwanda. This study, therefore, aimed at assessing the effectiveness of the Community-Based Approach (CBA) for IPV victimisation and perpetration as well as its associated mental health outcomes in Rwanda. Methods: A randomised controlled trial was conducted on a sample of 32 couples, with 17 couples assigned in treatment group and 15 assigned in control group. Data analyses were computed using mixed ANOVAs to evaluate the effect of CBA over IPV occurrence and mental health outcomes. Results: The results revealed a noticeable difference across the time points for IPV, anxiety, and depression, while the difference was not significant for PTSD. All variables showed a significant difference between groups, including IPV, anxiety, depression, and PTSD. Additionally, there was a meaningful interaction between time and group for IPV, anxiety, and depression. A similar interaction was also observed between time and sex for both anxiety and depression. Notably, both males' and females' IPV scores decreased to nearly the same level, while anxiety and depression scores declined more in females than in males. Conclusion: Our findings highlight substantial efficacy of CBA for victims and perpetrators of IPV in reducing IPV, anxiety and depression symptoms in Rwanda, a post-genocide country.
