The No Means No South Africa Evaluation Study

This protocol describes a mixed method evaluation study of a behavioral intervention-the No Means No (NMN) intervention-to reduce violence among enrolled girls, ages 10-19.

The No Means No intervention is an 8-12-hour behavioral intervention designed to teach Empowerment Self-Defense (ESD) to girls. A parallel intervention with boys focuses on violence perpetration by addressing issues of consent and bystander intervention. The intervention also includes a network of referrals.

The intervention will be evaluated through a cluster-randomized, controlled trial and a nested qualitative study. Implementation sites such as schools and afterschool programs (hereafter collectively referred to as schools) will be randomized to receive the girls' intervention only, the girls' and boys' interventions in parallel, or the control condition (standard of care). Control arm schools will receive the intervention as is following the study period if proven safe and effective. The study will enroll a subset of intervention participants (ages 10-19 years inclusive) at each intervention school, and an equal number of girls and boys at each control school. Experience and perpetration of sexual violence (SV), other forms of intimate partner violence (IPV), and community violence (CV) will be compared across the study arms over time, as well as engagement with referral services. At any timepoint when violence is disclosed, participants will receive first-line support and referrals for care. Participants will be followed longitudinally for 12 months.

Population: Approximately 2250 girls and 1000 boys, aged 10 to 19 years of age (inclusive) who are enrolled in 15 schools. Boys will be enrolled from the schools randomized to receive the boys' intervention and the control schools only.

Study Site(s): NMNW Implementation Site, Gqeberha, South Africa

Approach: This project will evaluate the impact of the No Means No intervention on SV prevention when paired with GBV referral services through a cluster randomized controlled study among girls and boys, with a nested qualitative component.

Study Duration: Accrual will require approximately 6 weeks. Participants in all study arms will participate in scheduled visits for enrollment (baseline), and 3, 6, and 12 months of follow-up. A subset of participants will be recruited for qualitative interviews (serial in depth interviews) to be conducted at or around 3 and 12 months post-intervention.

Primary Objectives:

• To test the effectiveness of the No Means No intervention in reducing girls' reported experiences of sexual violence (SV);
• To identify the mechanisms of action of No Means No on girls' reported experience of SV;

Secondary Objective:

• To determine the effectiveness of the No Means No intervention in reducing girls' reported experiences of other forms of violence (i.e. IPV, and CV);
• To compare the effect of simultaneous implementation of a boys violence perpetration prevention program, versus the girls' program alone or no intervention, on girls' reported experiences of SV;
• To examine change in boys' knowledge, attitudes, and behaviors related to violence perpetration as a result of participation in a prevention program.
