Predicting Suicidal Behavior in Veterans With Traumatic Brain Injury: The Utility of the Personality Assessment Inventory

In this study, we investigated the Personality Assessment Inventory's (PAI; Morey, 1991, 2007) Suicide Potential Index (SPI) and Suicide Ideation scale (SUI) as predictors of suicidal behavior (SB) in military Veterans with traumatic brain injury (TBI; N = 154). We analyzed electronic medical r...

Description
Summary:In this study, we investigated the Personality Assessment Inventory's (PAI; Morey, 1991, 2007) Suicide Potential Index (SPI) and Suicide Ideation scale (SUI) as predictors of suicidal behavior (SB) in military Veterans with traumatic brain injury (TBI; N = 154). We analyzed electronic medical records were searched for SB in the 2 years post-PAI administration and data via logistic regressions. We obtained statistical support for the SPI and SUI as predictors of SB. Analyses we performed using receiver operating characteristics suggested an optimal SPI cutoff of ≥15 for this sample. Findings suggest that SPI and SUI scores may assist in assessing suicide risk in those with TBI, particularly when population-based cutoffs are considered.
