The Cracow Instrument and Moffit's Developmental Theory of Juvenile Delinquency

2004

Abstract

Over the decade extending from the mid-1 980s to mid-1 990s, official crime statistics indicated a sharp upward trend in violent crime arrests of youth. A number of factors in the individual, family, and environmental domains have been shown to be associated with the etiology of juvenile violent crime and delinquency. Recently, a developmental perspective has gained influence in the understanding of delinquency, in which two distinct trajectories of antisocial behavior have been identified, hypothesized to result from interactions between different individual and environmental factors (Moffit, 1993(Moffit, , 1997)). The purpose of the current study was to investigate risk correlates of these distinct trajectories using a new, developmentally-oriented risk needs tool, the Cracow Instrument, Institutional records of 78 American male delinquent juveniles were reviewed. Results indicated small but significant differences between violent and nonviolent offenders in cognitive abilities, and problems in substance use and accommodation. Given a dearth of file information on risk in early developmental periods, no valid conclusions could be drawn regarding differences between early and late onset of antisocial behavior. Implications of results are discussed and suggestions for future research directions are provided. Division of Youth Corrections, in particular Edward Wensuc, Director of Research, for granting me permission to access institutional files, and Brent Nittmann, Director of Platte Valley Youth Services Center, for generous encouragement and inspiration. I would like to extend a warm thanks to Meghan Earthman for providing invaluable research assistance in the data collection stage of the project. I am indebted to my senior supervisor, Dr. Ronald Roesch, for advice and assistance in each stage of the project and to Dr. Marlene Moretti for helpful comments on early drafts. A special thanks goes to Joan Foster and Dr. Ray Koopman for hours of statistical consultation and problem solving-your patience and generosity in sharing your time, knowledge and resources are truly appreciated. Finally, a heartfelt thanks goes to my beloved family and dear friends for their continual encouragement and belief in me that kept me going in times when I felt deflated: mom, dad, Susanne, Matt Chandler, Ahna-Kristina Phillips,
