Factors associated with treatment acceptance and compliance among incarcerated male sex offenders

The files of sex offenders who had been offered treatment at a medium-security state prison were divided into three groups: treatment refusal ( n = 59), treatment noncompliance ( n = 61), and treatment compliance ( n = 36). Demographic, offense-related, clinical, and psychological assessment data were collected. Significant differences were found between groups on years to parole eligibility; plea; relation to victim; childhood sexual victimization; and Minnesota Multiphasic Personality Inventory–2 Variable Response Inconsistency (VRIN), Lie (L), and Masculinity–Femininity (Mf) scale scores. Logistic regression analyses revealed that significant predictors of treatment refusal include increased time until parole eligibility and lower VRIN and Mf scores (vs. noncompliant) as well as no history of childhood sexual victimization and higher L scores (vs. compliant). Having entered a not-guilty plea was the only significant predictor of noncompliance among those who initially accepted treatment. These findings are discussed in relation to previous studies of sex offender treatment compliance and directions for future research.
