About

The goal of this research project is to explore if levels of inflammation predict levels of comorbid mood disorders and treatment success in chronic pain patients. More knowledge in this respect will advance our understanding of chronic pain and comorbid syndromes, and facilitate subgroupings of patients based on the presence and/or level of low-grade inflammation. This research is an important step towards finding an explanation to why treatment effects following behavioral interventions differ across individuals, and generate new hypothesis regarding novel treatment approaches. The specific aims are: 1) to explore if baseline levels of inflammatory biomarkers predict the effects of behavioral intervention and 2) to investigate if baseline levels of inflammatory biomarkers are associated with psychological co-morbidity (e.g. depression, anxiety and fatigue) in patients with chronic pain.
