Presented are nine papers given at a New Zealand symposium on the prevention and treatment of delinquent/antisocial behavior in children and adolescents. Major theories such as the cultural deviance theory are noted in the introduction by D.R. Mitchell. J. E. Ritchie defines delinquency as law breaking, critiques delinquency research, and offers a paradigm of social forces for analysis. Considered by B. C. Atwool is whether punitive measures and isolation can be reconciled with effective therapy for institutionalized delinquents. Sociological perspectives of delinquency are examined by D. Chapple. Among recommendations for the prevention of delinquency by I.J. McKissack is prevention of opportunities for crime and refinement of methods for dealing with distrubed offenders. Procedures of the New Zealand courts in dealing with juvenile delinquents are reviewed by A. C. Rounthwaite. R. A. Austin gives a critical look at the rationale and efficacy of the legislative and punitive approach to delinquency. B. S. Parsonson reviews applications of behavior modification to delinquent behaviors. The previous seven papers are assessed by J. F. Thompson who notes the common assumption of delinquency as a social problem, I. J. McKissack responds to Thompson's comments and defends his concept of social maturity. (DB)
