This is the follow-up to an observational epidemiological study of psychological and
neuropsychological outcomes of deployed and non-deployed Gulf War-era veterans.
Approximately 800 deployed and 250 nondeployed veterans were originally administered
psychological assessment instruments shortly after the cessation of the Gulf War. These
veterans are currently being followed to evaluate longer-term psychological outcomes in
relation to war-zone stress, intervening life stress, and individual difference factors and
personal resources, such as coping and social support.
Approximately 75 of these veterans, oversampled for post-traumatic stress disorder, were
administered a specialized neuropsychological battery emphasizing attention and memory.
This sample will also be followed to evaluate longitudinal neuropsychological outcome in
relation to PTSD status.
A cross-sectional study will also be conducted examining visual, hierarchical attention in
relation to PTSD diagnosis.
