Negative and positive cognition in depressed and nondepressed chronic-pain patients.

Abstract

Several studies have suggested that depressed pain patients evidence more cognitive distortion than nondepressed pain patients and healthy controls. Although these studies have generally supported notions relating cognitive distortion to depressive functioning, other aspects of dysfunctional cognition have not been assessed in the chronic-pain population. The present study examined negative and positive automatic thoughts and attributional style in depressed pain patients, nondepressed pain patients, and healthy controls. Depressed chronic-pain patients were found to exhibit significantly more negative automatic thoughts than nondepressed pain patients and healthy controls. Conversely, nondepressed chronic-pain patients reported significantly more positive automatic thoughts than did depressed patients and healthy controls. No significant differences were found for attributional style. These results suggest that different cognitive-behavioral interventions might be considered for depressed compared to nondepressed chronic-pain patients.
