Health concepts, peer-helping behaviours and the role of the peer network in passing health information was explored among street-involved youth in a city in northern British Columbia. Perceptions of 21 youth were gathered through interviews and/or focus group discussions. Data were analyzed using content analysis and were viewed through the lens of the health belief and health promotion models. Results indicate that street-involved youth form peer groups and that these peer groups provide some positive support but also reinforce some unhealthy behaviours. The youth provide one another with some information related to their health and are able to provide guidance as to who would prove to be effective peer health counsellors.
