BackgroundThe Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire is the most widely used upper extremity-specific health-status measure. The DASH score often demonstrates greater variability than would be expected on the basis of objective pathology. This variability may be related to psychosocial factors. The purpose of the present study was to investigate the correlation between the DASH score and psychological factors for specific diagnoses with relatively limited variation in objective pathology.MethodsTwo hundred and thirty-five patients with a single, common, discrete hand problem known to have limited variations in objective pathology completed the DASH questionnaire, the Eysenck Personality Questionnaire-Revised (EPQ-R) to assess neuroticism, the Center for Epidemiologic Studies-Depression (CES-D) scale to quantify depressive symptoms, and the Pain Anxiety Symptoms Scale (PASS). Forty-five patients had carpal tunnel syndrome, forty-four had de Quervain tenosynovitis, forty-eight had lateral elbow pain, and seventy-one had a single trigger finger. In addition, twenty-seven patients were evaluated six weeks after a nonoperatively treated fracture of the distal part of the radius. Relationships between psychosocial factors and the DASH score were determined.ResultsA significant positive correlation between the DASH score and depression was noted for all diagnoses (r = 0.38 to 0.52; p < 0.01 for all). The DASH score also correlated with pain anxiety for four of the five diagnoses (carpal tunnel syndrome, r = 0.40; de Quervain tendinitis, r = 0.46; lateral elbow pain, r = 0.42; and trigger finger, r = 0.24) (p < 0.05 for all). The DASH score was not correlated with neuroticism for any diagnosis. There was a highly significant effect of depression (as measured with the CES-D score) on the DASH score for all diagnoses. Both the CES-D score (F = 62.68, p < 0.0001) and gender (F = 11.36, p < 0.001) were independent predictors of the DASH score.ConclusionsSelf-reported upper extremity-specific health status as measured with the DASH score correlates with depression and pain anxiety but not neuroticism. These data support the contention that psychosocial factors have a strong influence on health-status measures.
