BACKGROUND: Women living in war-affected contexts face high levels of gender-based violence, including intimate partner violence (Stark & Ager, 2011). Despite well-documented negative consequences, including posttraumatic stress disorder (PTSD) (Garcia-Moreno et al. 2006; Steel et al. 2009), evidence remains thin regarding intervention effectiveness to mitigate consequences in these settings. METHODS: This study used a two-armed parallel pilot randomized controlled trial to compare the impact of a group savings only (control) to gender dialogue groups added to group savings (treatment) on women's symptoms of PTSD in northwestern Côte d'Ivoire. Eligible Ivorian women (18+ years, no prior experience with group savings) were invited to participate and 1198 were randomized into treatment groups. RESULTS: In the ITT analyses, women in the treatment arm had significantly fewer PTSD symptoms relative to the control arm (β: -0.12; 95% CI: -0.20 to -0.03; p = 0.005). Partnered women in the treatment arm who had not experienced intimate partner violence (IPV) at baseline had significantly fewer PTSD symptoms than the control arm (β = -0.12; 95% CI: -0.21 to -0.03; p = 0.008), while those who had experienced IPV did not show significant differences between treatment and control arms (β = -0.09; 95% CI: -0.29 to 0.11; p = 0.40). CONCLUSIONS: Adding a couples gender discussion group to a women's savings group significantly reduced women's PTSD symptoms overall. Different patterns emerge for women who experienced IPV at baseline v. those who did not. More research is needed on interventions to improve mental health symptoms for women with and without IPV experiences in settings affected by conflict.
