| Abstract: | This study evaluated the reliability and construct validity of the Generalized Work Distress Scale in 207 patients attending a specialty clinic with work-related upper extremity disorders. Factor analyses were conducted and compared to the original developmental study confirming a two-factor solution: an internal factor related to Work-Related Dysphoria and an external factor related to Work-Related Support. Reliability (internal consistency) of factors was high (Cronbach s  = 0.87 and 0.89). The Work-Related Dysphoria factor was more related to self-reported global depressed mood and self-reported upper extremity functional disability, than was Work-Related Support. This study provided preliminary support for the use of this scale in patients with work-related upper extremity disorders and consideration to depressive symptoms in these patients. Further investigation of the psychometric properties of this scale and its predictive validity are required. |
