Psychological and contextual factors play an important role in the development and maintenance of chronic spine-related pain, and effective treatment of pain-related conditions requires an understanding of how these factors contribute to pain and disability. The present study examined the relative contributions of spine pathology, psychological complications, and demographic factors to perceived pain intensity and disability in patients with chronic spine-related pain. Because most patients were assessed in the context of a compensable injury, exaggeration of symptoms and disability was systematically controlled for using multiple validity indicators. A high prevalence of psychological complications was observed in the present sample. Analysis indicated that psychological factors were not significantly related to pain intensity, but were significantly related to reported pain-related disability. Further, psychological factors were found to predict pain-related disability beyond demographics, medical findings, and pain intensity. Clinical implications of these findings are discussed.
