Assessing posttraumatic stress disorder with the MMPI-2 in a sample of workplace accident victims

In this study, the predictive capacity of the Minnesota Multiphasic Personality Inventory–2 Posttraumatic Stress Disorder–Keane (MMPI–2 PK) scale was examined in a sample of trauma victims who experienced a serious workplace-related accident and subsequent injury. In keeping with a number of previous investigations, the PK scale was largely ineffective in identifying posttraumatic stress disorder (PTSD) beyond overall symptom and functional severity. In contrast, sets of clinical and content scales proved to be significant predictors of PTSD. These findings suggest that the PK scale is not particularly useful in detecting PTSD in civilian trauma samples. Clinicians might be best advised to use the MMPI–2 clinical and content scales in their assessment of PTSD in civilian patients presenting with a history of trauma.
