The COVID-19 pandemic and the government policies designed to contain it have created severe economic and mental health challenges in many low-income countries. In this study, we examine whether a maternal mental health intervention, delivered from pregnancy through 3 years postpartum, provided resilience amidst COVID-19 restrictions in rural Pakistan. Our findings show that women who were randomized into receiving therapy experienced 0.26 standard deviations fewer common mental disorders such as anxiety and depression. They also reported improved spousal relationships, fewer marital problems, and a lower frequency of intimate partner violence during periods of more stringent government restrictions, as compared to women who did not receive the intervention. Our results suggest that these effects may be the result of an improved ability to manage stress and worry, rather than from differing experiences of economic shocks among the treatment arm.
