In this investigation, the effects of unexplained fatiguing illness and psychiatric disturbance on functional status and quality of life in Gulf War veterans (GWVs) was examined. Twenty-nine GWVs with unexplained fatigue (Fukuda et al., 1994) and an Axis I psychiatric diagnosis, 19 GWVs with fatigue and no Axis I psychiatric disorder, and 45 healthy GWVs were evaluated. GWVs with unexplained fatigue suffered from significant functional decline and decreased well-being in all spheres, relative to healthy GWVs. Veterans with comorbid psychiatric illnesses demonstrated the most impaired functioning on measures of life quality that emphasized psychological well-being, but they did not demonstrate reduced physical functioning relative to other fatigued veterans. Thus, reduced physical functioning and well-being in GWVs cannot be attributed to psychiatric disturbance but seems to result from unexplained fatiguing illness.
