Sponsor's own description

Leaders in Action (LIA) is a norms-centered intervention that aims to reduce the acceptance and prevent the incidence of Intimate Partner Violence (IPV) in Peru by shifting social norms. This project takes advantage of the randomization of LIA across 250 villages.

LIA has two delivery models: a household-based module (HT), consisting of household training sessions by Community Health Volunteers, and a group-based module (GT) with education sessions in small gender-segregated groups organized by trained facilitators. The investigators will cross-randomize each approach to assess efficiency in reducing domestic violence and changing social norms about tolerance toward violence and gender roles. The study disentangles the impact of the two modules separately, as well as the interaction of the modules, while explicitly addressing methodological concerns of previous studies: reporting bias from self-reported domestic violence, limited statistical power and lack of long-term effects measures.

Potential and actual victims of IPV may profit from the intimate atmosphere of household visits, and that on the side of women, the transmission of information about IPV and services for victims may be facilitated in more private settings. At the same time, group-level workshops about harmful gender stereotypes and gender norms for women should, through social interactions and norm change, reinforce the effects of household-level treatments for women. The experiment will shed light on the potential mechanisms at play and the theoretical framework underlying IPV through extensive data collection and the calculation of heterogeneous effects. The goal of this project is to deliver new rigorous evidence to the scientific and policy community by experimentally evaluating the impact of a state-run IPV intervention and its main components. It provides insights into the effectiveness of distinct program components, assesses cost-effectiveness as well as potential to scale, and evaluates the mechanisms leading to the reduction of IPV.
