Assessed the effects of the Persian Gulf War on the psychological health and adjustment of military personnel in Hawaii and Pennsylvania, 1,524 of whom did and 2,512 of whom did not deploy to the Persian Gulf during Operations Desert Shield/Desert Storm. Ss anonymously completed a questionnaire providing information on demographics, psychological and psychosocial health, deployment stressors, current life problems, current distress, and causal attributions of present problems. Deployed Ss experienced significant levels of stress during deployment and continued to report significant stress in their present lives. Although deployed Ss' scores on the Brief Symptom Inventory were high compared with those of civilian nonpatients, their scores were essentially identical to those of nondeployed Ss. Although considerable stress was experienced, most Ss were handling it unremarkably.
