Description/Overview: Dating violence is defined as the physical, sexual, or psychological violence within a dating relationship, including stalking. Since the past decade, dating violence has been identified as an emerging public health issue among young couples and is linked to poor physical and mental health outcomes including injuries, depression, as well as behavioural problems such as suicidal attempts, eating disorders, unplanned pregnancies, and substance abuse. University students are at high risk for dating violence because they have time and space to socially interact with each other without parental guardianship. They may also cohabitate in the same building in dormitories, which increase the personal risk of being physically or sexually abused if the dating partner is abusive. Further, peers are often aware of dating violence but feel ill equipped to help and experience distress at helping. Limited research explores prevention efforts for older adolescents on dating violence and few programs use a community level, peer based approach. This symposium introduces two programmes, Friends Helping Friends in the United States and Dating Café Ambassadors Programme in Hong Kong. Both of them are bystander education programme which have been conducted to address the local needs to prevent dating violence in university campuses. Both programs were designed to provide education, training, and skills to enable older adolescents to help peers who are in dating violent relationships. The presenters will discuss the theoretical underpinnings of the bystander, community level prevention strategies and report on the evaluation of each program. Program evaluation used a pre and post-test design to compare attitudes, beliefs, behaviours, and intention to act as a bystander between treatment and control groups. The presenters will also address challenges to conducting violence research; including human subjects concerns, cultural considerations, and population specific barriers. Implications for future research, campus policy, and clinical practice will be addressed.
