Brief Summary
Chronic widespread pain (CWP), defined as long-lasting pain in multiple body regions, has a prevalence of 10-14% in Europe and is associated with other physical symptoms such as fatigue and cognitive problems. Individuals with longstanding pain also have a high prevalence of sleep disturbances, and sleep problems can in itself lead to tiredness, lower neurocognitive function and higher pain ratings. However, studies of comorbid sleep problems for individuals with CWP are a lacking, and the primary aim for the present study is to assess the prevalence of sleep disturbances in individuals with CWP, and to see how this covariates with pain, fatigue, activity level, neurocognitive functioning, and biomarkers. As a secondary aim the study will assess a subgroup of the individuals, that has received multimodal pain management treatment, a second time after 6 months to analyze how the prevalence of sleep disturbances and other associated problems covaries over time.
