High-risk sexual behaviour has been linked to social problems such as substance abuse, domestic violence, homelessness, and deprivation. This volume's multidisciplinary biopsychosocial approach combines relevant medical information regarding disease states with the cultural, social, and psychological facets of successful prevention programmes. Becker and Rankin outline specific interventions that address the needs of particularly vulnerable populations: women, ethnic minorities, and the gay community. Useful chapter summaries which review the pros and cons of different approaches should aid both the student and the practitioner.
