The document outlines a primary prevention intervention in Cambodia aimed at addressing violence against women and girls (VAWG) by working with adolescents and their caregivers. The initiative, titled “Developing Healthy and Happy Relationships,” targets adolescents aged 12 to 14 and focuses on mitigating risk factors associated with intimate partner and non-partner violence, such as low gender equitable attitudes and poor relationship skills. The intervention emphasizes the importance of engaging young people in changing social norms during early adolescence, a critical period for shaping attitudes towards relationships. Implemented by the Provincial Department of Women’s Affairs with support from various organizations, the program includes community sessions, training for facilitators, and the development of educational materials. The document also highlights the need for interministerial collaboration to integrate relevant topics into school curricula and to mobilize resources for scaling up the intervention across Cambodia.
