8. Mentoring to reduce offending • Anti-social behaviour in childhood and adolescence is a problem for young people, their families, the police, communities and politicians • In 2003, the Government announced funding for mentoring schemes in England, arguing that ‘mentors can make a real difference to... some of the most vulnerable people ....There are ... excellent examples of schemes which really work’. • Mentoring is non-invasive and does not require drug treatment. It is easy to see why it might work, and why it might be attractive to politicians and policy makers. • Unfortunately it can have the reverse of the desired effect

9. What might help in working out what works? • Reversing the lack of a rigorous outcome evaluation culture • Recognition that quick fixes are rare and that social and educational interventions have as much or even more potential to do good or harm as health interventions

10. What else might work ? • Include high quality qualitative and ethnographic studies • Paying greater attention to the experiences of people on the receiving end of interventions, policies and practices (c) Helen Roberts
