Child safety is everybody's concern, but much professional activity is misinformed or based on a misrepresentation of the facts, and preventative action is rarely adequately evaluated. Written and edited by leading researchers with an active role in social policy, this new book challenges both our understanding of the problem of child safety and points to the impotence of "educational" approaches based on "knowledge enhancement". The strong message is that improving children's knowledge has little or no effect on their behaviour. From the physical abuse of young children to drug abuse in adolescence, this book presents a radical new perspective on a key social issue.
