Changing risk factors that impact recidivism: in search of mechanisms of change.

The present study examined whether treatment change among offenders under community supervision would predict reductions in recidivism. The intervention program, based on cognitive-behavioral principles, focused on changing antisocial attitudes. Compared to a matched control group, the likelihood of reduced recidivism was 57% for the binary outcome and 70% for the multiple count outcome, after controlling for past program participation, propensity score, and days of opportunity to offend. The within-person pre-/postchange scores showed less promise in predicting recidivism. Only changes with a single antisocial associate measure, which were not central to the treatment program, predicted future recidivism. Caution must be used in the idiographic assessment of dynamic risk and treatment change. PsycINFO Database Record (c) 2013 APA, all rights reserved
