In 1990-1991, shortly after the Persian Gulf War, a number of veterans began complaining about a wide range of symptoms, the most common of which were; fatigue, headache, sleep disturbance, low mood, and memory loss. These symptoms were similar to those experienced by individuals with Medically Unexplained Illnesses such as Chronic Fatigue Syndrome, Fibromyalgia, Irritable Bowel Syndrome, Multiple Chemical Sensitivity, and Somatoform Disorders. Utilizing structural equation modeling and data gathered from the Gulf War Veterans Health Questionnaire, this study attempted to determine whether symptoms experienced by veterans were best explained as individual items, discrete illnesses, or as a conglomeration of symptoms (i.e. Gulf War Illness). Three models were proposed: a single factor, a five factor, or a second order model, and run in EQS. Results indicate a strong fit for the second order model indicating the presence Gulf War Illness as a separate, unifying concept that best accounts for symptoms experienced by veterans of the Persian Gulf War. Treatment recommendations and future considerations are discussed.
