Type of intervention     

Workshop instructional sessions designed to provide girls with the skills to protect them from sexual violence and enable boys to challenge sexual violence. This includes provision of self-defence training and for girls and active bystander training for boys. The No Means No approach has been informed by empowerment self-defence research, including the evidence-based IMpower methodology. The program has been delivered in Kenya, Malawi, Uganda, Nigeria, Ethiopia, the U.S., and South Africa and is scaling up to additional geographies.

Description of intervention 

The No Means No curriculum is divided by gender and includes role play opportunities to practice practical skills. Girls participate in sessions which empower them with a variety of skills to help protect them from sexual violence. The content explores definitions of sexual violence, seeks to improve self-esteem, improve self-efficacy in boundary creation and assertive communication; and verbal and physical self-defence skills and de-escalation techniques. Meanwhile, the curriculum for boys delivers skills in resilience, breaking down harmful gender stereotypes and rape culture, consent, respect for women and active bystander skills.


In one report of the program in Kenya, rape incidents decreased by 51% for participants. Fifty percent of girls reported stopping a rape in the following year and bystander interventions rose from 26% to 74%. Additionally, school drop-out due to pregnancy decreased by 46% (IZA World of Labour, 2017).

Baiocchi et al. (2017) report a 3.7% decrease in risk of sexual assault for girls who have participated in IMPower compared to controls. This was reviewed within a cluster-randomised, matched-pairs trial of interventions. During this, boys participated in an adapted version of IMPower called 50:50.

In a non-randomised, single-arm trial of program efficacy with 4th and 5th graders on a Native American reservation, the No Means No program increased knowledge of child sexual abuse and efficacy in resisting an attack or assault (Edwards et al., 2020).
