Clinical Utility of the Minnesota Multiphasic Personality Inventory–2–Restructured Form (MMPI-2-RF) in a Residential Treatment Program for Homeless Individuals

The current study examined the clinical utility of the Restructured Form of the Minnesota Multiphasic Personality Inventory–2 (MMPI-2-RF) in a residential treatment program for homeless individuals. MMPI-2-RF scale scores from 146 participants with valid profiles were correlated with variables obtained at intake and during treatment. The sample was then followed 12 months postdischarge to test preregistered hypotheses regarding MMPI-2-RF predictors of hospital readmissions. The results indicated that a variety of MMPI-2-RF scale scores were correlated with historical and diagnostic variables at intake and with measures of treatment outcome, including behavioral problems and successful outcome. A broad range of MMPI-2-RF scale scores were related to readmissions postdischarge and many of these relationships remained significant when tested in Poisson regression models containing other predictors. However, the postdischarge findings were generally inconsistent with our predictions and were of small effect size. The clinical implications of MMPI-2-RF results for residential treatment programs are discussed.
