Purpose: To identify subgroups of chronic pain patients based on the occurrence of depression, anxiety, and catastrophizing and the duration of pain and pain intensity. In addition to this, to investigate the relationship between the subgroups with respect to background variables, diagnosis, pain-related disability, and perceived quality of life.
Methods: This study used 433 chronic pain patients including 47 patients with spinal cord injury related pain, 150 with chronic whiplash associated disorders, and 236 with fibromyalgia. The participants answered a postal questionnaire that provided background data, pain intensity and duration and psychological and health related items.
Results: Based on depression, anxiety, catastrophizing, pain intensity and duration, we identified subgroups of chronic pain patients that differed with respect to perceived quality of life, disability and diagnosis. The psychological factors, especially depression, significantly influenced perceived quality of life and disability. Pain intensity and duration play a minor role with respect to quality of life although pain intensity is associated contributes more to perceived disability.
Conclusions: The results of this study highlight the importance of not looking at chronic pain patients as a homogenous entity. A detailed assessment, including psychological factors with emphasis on depressive symptoms, might be essential for planning and carrying through treatment and rehabilitation.
