Assessment of Sex Offenders With the Minnesota Multiphasic Personality /Inventory–2–Restructured Form

Abstract

This study examined the association between scores on the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) with static and dynamic risk assessment instruments, including the STATIC-99 and Level of Service Inventory-Revised (LSI-R). The sample included 304 male adults who were convicted of sexual offenses against children and were referred to a sex offender treatment program. On average, the sample had a Low-Moderate risk of re-offending according to the STATIC-99 and LSI-R. The results indicated that MMPI-2-RF scale scores in this setting are characterized by relatively high levels of under-reporting and externalizing psychopathology compared with the normative sample. We also found that scale scores in this sample produced reliability estimates that were similar to the normative sample. Finally, external correlations between the MMPI-2-RF scales and the risk assessment instruments indicated that the test was associated in expected ways with constructs measured by these instruments. Correlations were most robust among scales in the externalizing/behavioral dysfunction domain of the MMPI-2-RF. Overall, the results of the study support and guide use of the test in this population.
