Utility of the MMPI-2 Restructured Form (MMPI-2-RF) in a Sample of Lithuanian Male Offenders
The aim of the current study was to examine the construct validity of the Multiphasic Personality Inventory-2 Restructured Form (Minnesota Multiphasic Personality Inventory [MMPI]-2-RF; Ben-Porath & Tellegen, 2008/2011) in a correctional setting. More specifically, we examined the associations between MMPI-2-RF scales with external variables relevant for sentence planning as well as the relationship with risk of reconviction assessed with the Offender Assessment System (OASys; Home Office, 2002). A random sample of 228 male offenders from Lithuanian custodial institutions was selected for the study. The results revealed that MMPI-2-RF scale scores differentiated offender groups classified on the basis of external variables, such as history of suicide attempts, violent offending, use of drugs, violence under the influence of alcohol, and early criminal onset, in a manner consistent with conceptual expectations. Moreover, Behavior/Externalizing Dysfunction (BXD), Antisocial Behavior (RC4), Juvenile Conduct Problems (JCP), Substance Abuse (SUB), and Disconstraint-Revised (DISC-r) scale scores evinced correlations with OASys scores that were moderate in magnitude. Results from regression analyses showed that MMPI-2-RF scale scores accounted for approximately 21% of variance of OASys risk of reconviction scores. Overall, the findings provide support for the utility of the MMPI-2-RF in Lithuanian correctional institutions.
