This study examines the relationship of institutional misconduct to postrelease rearrest, controlling for a battery of preincarceration variables typically found to influence recidivism among institutionalized delinquent offenders. Based on data from 1,804 serious and violent male delinquents released from a large southern juvenile correctional system, this research found limited support for institutional misconduct as a determinant of recidivism. Of all measures of misconduct, only the rate of total misconduct infractions was related to postrelease rearrest, and this effect was generally small and found only in the rearrest frequency model, not the dichotomous rearrest model. Implications for research and practice are explored. (Contains 3 tables and 6 notes.)
