PTSD, posttraumatic stress disorder; SF-12, 12-Item Short Form Health Survey.

Pairwise differences significant at P <.05 are displayed. Pairwise tests were conducted only when the omnibus test was significant at P <.05 and values for significant comparisons are reported in the results section.

Assessed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I).

Impairment was defined as a score ≥7 (marked or extreme impairment).

Assessed with the Medical Outcome Study SF-12. Higher scores are more favorable.
