This book presents a comprehensive summary of how well adult crime, antisocial behaviour and antisocial personality disorder can be prevented by interventions applied early in life. It reviews important childhood risk and protective factors for these adult outcomes and the alternative strategies of primary prevention (targeting the whole community) and secondary prevention (targeting persons identified as high risk) are discussed. The book also contains extensive information about prevention programmes in pregnancy and infancy, pre-school programmes, parent education and training programmes, and school programmes (including the prevention of bullying). There is special emphasis on preventing the intergenerational transmission of antisocial behaviour by focusing on family violence, and a special review of whether risk factors and prevention programmes have different effects for females compared to males. Cost-benefit analyses of early prevention programmes are also reviewed, leading to the conclusion that adult antisocial behaviour can be prevented both effectively and cost-efficiently.
