Abstract

War stress frequently leads to the subsequent development of psychopathology including posttraumatic stress disorder (PTSD), but recent research has indicated that individual difference factors may alter vulnerability to trauma-related distress. In an effort to examine the potential buffering effects of intellectual resources on PTSD development, this study assessed intellectual functioning in subsets of Persian Gulf War zone veterans with and without PTSD diagnoses. The two subsets, comprised of 18 PTSD-diagnosed and 23 psychopathology-free Persian Gulf War veterans, were compared on a multi-faceted test of intellectual functioning, the Wechsler Adult Intelligence Scale-Revised. As compared to psychopathology-free veterans, PTSD-diagnosed veterans performed significantly more poorly on tasks of verbal intellectual functioning including those tasks thought to reflect premorbid functioning. The two groups did not differ on visuospatial tasks or on a task of attention. Findings suggest that intellectual resources, particularly verbal skills, may buffer development of stress-related psychopathology following trauma exposure.
