Longitudinal stability of fibromyalgia symptom clusters

Using self-report questionnaires of key fibromyalgia symptoms domains (fatigue, sleep disturbance, pain, function, stiffness, dyscognition, depression, and anxiety) we previously identified four unique symptom clusters. The purpose of this study was to examine the stability of fibromyalgia symptom clusters between baseline and two years follow-up. Female patients with a diagnosis of fibromyalgia completed a baseline Brief Pain Inventory, the 30-item Profile of Mood States, the Medical Outcomes Sleep Scale, the Multidimensional Fatigue Inventory, the Multiple Ability Self-Report Questionnaire, the Fibromyalgia Impact Questionnaire-Revised, and the Medical Outcomes Short Form-36.
