- University of Witwatersrand, South Africa
- Brief Summary
South Africa has one of the highest rates of violence towards women globally. However, little is known about how to prevent men's use of violence. The Sonke CHANGE Trial tests an intervention that targets men as individuals, groups, and community members in a peri-urban setting in South Africa. Eighteen neighborhoods will be randomly assigned to either the intervention condition or a control group. By speaking to men at baseline, 12 months, and 24 months, investigators will learn whether violence and other health behaviors shift over time. Alongside the trial, qualitative research will explore how the intervention took place and why participants may change attitudes or behaviors.
- Detailed Description
This study will refine and evaluate a multi-level model for reducing violence against women and girls in urban South Africa.
The intervention is a refinement of an existing gender-transformative programme that includes community mobilisation and advocacy. Called the Sonke CHANGE intervention, it will extend beyond a conventional group-based workshop approach to address the multi-level nature of violence and create an enabling environment for men to embrace more equitable forms of masculinity. Given the strong associations between masculinities and men's use of partner violence, now is an opportune moment to test the Sonke CHANGE model to determine its impact on men's use of violence.
The multi-level Sonke intervention will be evaluated using a cluster randomised controlled trial design. In a peri-urban setting of Diepsloot, neighbourhood "clusters" (n=18) will be randomly assigned to receive the intervention or a wait-list condition. Baseline, 12 month, and 24 month measures will assess changes in primary outcomes (men's reported use of intimate partner and non-partner violence) and secondary outcomes (severe violence, masculinity norms, harmful alcohol use, mental health). Formative qualitative research will explore the environmental context of Diepsloot, community views on violence, men's mobility, and their experiences of fathering. A longitudinal process evaluation will explore intervention delivery, unfolding of the advocacy element of Sonke CHANGE intervention, and potential mechanisms to change amongst participants.

- Primary Outcome Measures
Name Time Method Change in intimate partner violence 12 months, 24 months Men's use of violence towards an intimate partner will be measured using an adapted version of the questionnaire from the South African Medical Research Council's Study on Men's Health and Relationships (6, 61). The questionnaire includes items around emotional abuse, economic abuse, physical violence, and sexual violence. Primary outcomes will be defined as dichotomous outcomes: any use of physical violence and / or any use of sexual violence.
- Secondary Outcome Measures
Name Time Method Change in severe violence 12 months, 24 months Men's use of severe violence is defined as any instance of men reporting more than once response to a single physical or sexual IPV item OR a response of once or more than once to two or more physical and/or sexual items.
Change in controlling behavior 12 months, 24 months Male Controlling Behaviour will be measured using the Pulerwitz Sexual Relationship Power and Control scale items (65). This scale has been validated in South Africa (66), and has been used by members of our team in previous studies (67).
Change in gender attitudes 12 months, 24 months Gender Attitudes will be measured using the Gender Equitable Men's Scale (GEM Scale) (63), an 18-item Likert scale. Gender Norms will be comprised of similar items, but phrased in a Likert scale for whether a man's friends hold those beliefs.
Change in harmful alcohol use 12 months, 24 months Harmful alcohol use will be measured using the Alcohol Use Disorders Identification Test (AUDIT), a 10-item scale designed to measure alcohol consumption and identify risks for alcohol abuse and dependence (62).
