Personality patterns of male felons in a correctional halfway house setting: an MMPI typological analysis

The MMPI profiles of 184 male felons who were residing in a correctional halfway house setting were cluster analyzed using S. Johnson's (1967) method to empirically identify different personality types. The samples ranged in age from 19 to 60 years and included three legal status groups: state parole, federal pre-release, and state furlough. Eight MMPI groups were derived and interpretive summaries provided. The eight types were compared across 13 demographic and descriptive variables with significant differences among groups found for age, prior felony convictions, and prior incarcerations using ANOVA. Diagnostic and treatment concerns were discussed.
