The Predictive and Incremental Validity of Two Self-Report Risk Assessment Measures With Adult Male Offenders Who Have Mental Health Problems

We examined the predictive and incremental validity of two self-report risk assessment measures—the Self-Appraisal Questionnaire (SAQ) and the Measure of Criminal Attitudes and Associates (MCAA)—in a sample of 121 adult male offenders, with mental health problems in a correctional treatment setting. Both the SAQ and MCAA were significantly and positively correlated with a standard risk/need assessment currently used in corrections, the Level of Service Inventory–Ontario Revision (LSI-OR). All three risk measures significantly predicted general recidivism within 1 year of follow-up. The SAQ and LSI-OR also significantly predicted institutional incidents (threat, verbal aggression, or assault). In addition, the MCAA significantly added to the prediction of general recidivism provided by the LSI-OR, whereas the SAQ did not, likely reflecting the relatively high content overlap of the SAQ and LSI-OR. Neither self-report measure added to the ability of the LSI-OR to predict institutional incidents involving ag...
