Personality Assessment Inventory Scores as Predictors of Treatment Compliance and Misconduct among Sex Offenders Participating in Community-Based Treatment

This study examined the ability of the Personality Assessment Inventory scores to predict noncompliance and probation revocations among a sample of sex offenders mandated to participate in community-based treatment. Scores on the Borderline Features (BOR) scale and subscales were the strongest predictors of noncompliance, with effect sizes as large as d = 1.50, outperforming scores on scales designed to predict treatment rejection and antisocial traits. Relatively low BOR cut scores (e.g., 50T, 55T) appeared to be most useful for identifying those at risk for noncompliance, suggesting that those with even moderate levels of borderline or personality disorder traits may be at risk for noncompliance.
