The Behavioral Insights Team (BIT), Praekelt.org, Wits University, and the University of North Carolina are pleased to announce the publication of our research in PLOS Digital Health. The study, titled “Effects of digital chatbot on gender attitudes and exposure to intimate partner violence among young women in South Africa,” tests whether a WhatsApp chatbot can reduce intimate partner violence (IPV) by improving young women’s beliefs and skills around healthy relationships.
In South Africa, 1 in 5 women will experience intimate partner violence in their lifetime. Patterns of violence can start at an impressionable age, when teenagers and women start their first serious relationships and learn what is “normal”—or even desirable—in a partner. There is a strong connection between positive power equity beliefs and lower IPV prevalence. While evidence shows that traditional media can promote help-seeking and gamified platforms can improve health outcomes, our study is among the first to assess IPV exposure after having participants use a digital, interactive platform.
In 2021, BIT partnered with Praekelt.org and Wits University in research supported by the Wellspring Philanthropic Fund to address IPV through technology. Using behavioral science and IPV research, we developed ChattyCuz, a WhatsApp chatbot intervention. Throughout its development, we incorporated the voices of young South African women via workshops and advisory groups who made key decisions during the experimental trial.
ChattyCuz delivers content by chatting with participants, asking them to reflect on healthy relationships and to practice useful skills, such as identifying unhealthy relationship behaviors, seeking help from a trusted person, and planning for safety.
To see whether chatbots could improve attitudes and beliefs about power equity in relationships and reduce exposure to unhealthy relationship behaviors, we tested the effects of two treatment versions of ChattyCuz compared to controls:
19,643 young women in South Africa participated and were randomized into each group. We measured their exposure to unhealthy relationships and mental health three months after the intervention through a survey. People also took quizzes throughout the trial to measure outcomes.
Given the potential for chatbots to reach many users at low-cost, our results are valuable for organizations working to prevent IPV in South Africa and worldwide. More than 2 billion people use WhatsApp globally. Drawing from our research, similar chatbots or edutainment tools could be leveraged by governments and development organizations to address IPV in different countries and contexts, promoting healthy relationship behaviors at a large scale.
“We are excited about the impact that chatbots for behavioral change can have on the lives of millions of people in low- or middle-income countries.” —Paloma Bellatin-Nieto, Principal Advisor, The Behavioral Insights Team
