Typical MMPI-2 Profiles of Multiple-DWI Individuals

We identified the typical personality profile of individuals with multiple driving-while-intoxicated (DWI) offenses using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Multiple DWI offenders were recruited from outpatient clinics between January 2009 and September 2013. All participants were administered the MMPI-2 and also completed a questionnaire soliciting demographic information. A hierarchical cluster analysis was performed using Ward’s method. The multiple-offenders-I group (n?=?9) had relatively high (although still within normal) scores on the D and Pd scales. The multiple-offenders-II group (n?=?50) had low scores on both the Ma and Si scales and a V-shaped profile on the validity scales. Some multiple offenders may have poorer emotional adjustment, characterized by tendencies toward psychopathic deviance, mania, and depression, as well as psychopathological characteristics typically associated with patients with alcohol-use disorder.
