Disability Assessment with WHODAS 2.0 of People with Fibromyalgia in Poland: A Cross Sectional-Study

BACKGROUND Fibromyalgia (FM) is a multifactorial syndrome characterized by chronic widespread pain, fatigue, sleep and cognitive impairment and functional symptoms. The aim of this study was to assess disability and its associated factors. The study was conducted among 691 patients with fibromyalgia in Poland using an online survey. MATERIAL AND METHODS This was a cross-sectional study of the disability of patients with fibromyalgia aged 18 years and over in Poland. The study was conducted by means of an online questionnaire distributed to patients affiliated with the National Association of Patients with Fibromyalgia. A total of 691 records were analyzed. The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) 36-item version was used to assess disability. The Beck Depression Inventory was used to assess the participants' emotional state. Sociodemographic and selected health data were collected. RESULTS The study group had a significant general level of disability as measured by the WHODAS 2.0 (mean=49.69). The greatest limitations were found in the following areas: life activity (mean=73.43), social participation (mean=64.59), and mobility (mean=62.07). The categorical sociodemographic variables that statistically significantly differentiated the participants in terms of general level of disability were occupational status (P<0.005), pain level (P<0.001), number of medications taken (P=0.005), and level of depression (P<0.001). CONCLUSIONS Disability is present in fibromyalgia and is a major concern. Understanding the determinants of disability in fibromyalgia can contribute to the development of effective therapies and symptom relief.
