Studies of substance abuse among delinquents have shown mixed results on cr
iminal recidivism. The present study evaluates personality traits associate
d with substance abuse and recidivism among delinquent boys, and prospectiv
ely determines the extent to which these factors are predictive of criminal
recidivism. 134 incarcerated boys (x = 15.9 +/- 1.1) completed the Weinber
ger Adjustment Inventory and the Substance Abuse Screening Inventory. Youth
were prospectively followed for up to 4.5 years following release. Among i
ncarcerated delinquents, personality traits are predictive of a positive su
bstance abuse screen and recidivism. A trend indicating a possible interact
ion between personality and treatment is observed. If these findings are re
plicated, personality traits may play a role in predicting substance abuse
as well as individual delinquent responses to treatment.
