This paper reports the results of a cross-sectional survey of 11- to 16-year-old school-going youths in ten southern African countries. The survey instrument recorded both the experience of coerced sex and the perpetration of forced sex. There were prominent school and community risk factors for increased risk-taking behaviours, revictimisation and the perpetration of sexual violence. This supports the idea that the local culture can reinforce the antisocial consequences of sexual abuse of boys and girls. There was a suggestion that the school environment can compound the effects of child sexual abuse in terms of conscious knowledge, high-risk behaviour, the risk of revictimisation and disdain for the safety of others.
