BACKGROUND: There has been growing interest in symptom heterogeneity in posttraumatic stress disorder (PTSD), yet examinations of personality variation across symptom typologies have been largely limited to veteran samples.
METHODS: The present study expands this literature by examining self-reported PTSD symptoms (PTSD Checklist for DSM-IV) and potentially maladaptive personality traits (Millon Clinical Multiaxial Inventory-III) in 516 treatment-seeking World Trade Center (WTC) rescue, recovery, and cleanup workers (mean age = 51.1; 75% male).
RESULTS: Latent class analysis identified five distinct PTSD symptom profiles: severe (n = 216), low symptom (n = 82), threat arousal (n = 73), mild numbing-hyperarousal (n = 71), and avoidance-numbing-hyperarousal (n = 68). PTSD symptom heterogeneity was meaningfully associated with distinct patterns of personality scale elevations and the total number of clinical elevations observed.
CONCLUSIONS: These findings underscore the need for assessment strategies that integrate personality profiles into conceptualization of PTSD subtypes and suggest that personality-informed approaches may enhance treatment engagement or outcomes in populations with disaster-related occupational trauma exposure.
