Minnesota Multiphasic Personality Inventory-2-Restructured Form Markers of Future Suicidal Behavior in a Forensic Psychiatric Hospital
Past research indicates a need to integrate objective psychological testing with clinical interview data during suicide risk assessment. The current study evaluated the utility of the Minnesota Multiphasic Personality Inventory (MMPI)-2 Restructured Form (MMPI-2-RF) in the prediction of future suicidal behaviors in a sample of 1,110 forensic inpatients (807 males, 303 females). Results indicated that scales from all substantive domains of the MMPI-2-RF were significantly positively associated with future suicidal behaviors. Consistent with expectations, the best predictors were scale scores from the internalizing and externalizing domains of the inventory. Relative Risk Ratios indicated that individuals producing elevations on these scales were at 2 to 4 times greater risk of future suicidal behaviors compared with those who did not produce elevations. Implications of these findings and limitations of this study are discussed.
