Abstract

The purpose of this study was to validate the World Health Organization Disability Assessment Schedule (WHODAS) 2.0 12-Item Version in persons with Fibromyalgia Syndrome (FMS). Three hundred and two individuals with FMS completed an online survey consisting of the WHODAS 2.0 12-item version and measures of a variety of biopsychosocial variables. The results indicate that the WHODAS 2.0 12-item version exhibits a two-factor structure (Social and Cognitive Functioning and Self-Care Functioning), and the factors correlate with the selected biopsychosocial variables (pain intensity, fatigue, cognitive impairment, sleep problems, depression, and social support) in the expected directions. These results suggest that, although the WHODAS 2.0 12-item version does not exhibit the one-factor structure that has been found in other validation studies, it can be thoughtfully used to explore the impact of FMS on individuals' lives in clinical and research settings.
