A cluster randomised trial to evaluate the impact of a social empowerment intervention on intimate partner violence against women in newly formed neighbourhood groups in Tanzania

The MAISHA study (CRT02) is a mixed methods evaluation, including a cluster randomised trial (CRT) of a small group based social empowerment intervention to prevent intimate partner violence (IPV) against women in Mwanza city, Tanzania. The trial was conducted among women in newly formed neighbourhood groups, with these groups being the unit of randomisation and (in the intervention arm) the unit of intervention delivery. This dataset contains the results of two surveys conducted among trial participants, a baseline survey conducted prior to randomisation and a follow-up survey conducted 29 months later. It comprises 1,265 records (each pertaining to an individual trial participant). NB: Data pertaining to a second trial of the same MAISHA intervention conducted among women receiving microfinance (CRT01) are not included in this record.
