Reliability and factor structure of the Hospital Anxiety and Depression Scale in a polytrauma clinic.

Reliability and factor structure of the Hospital Anxiety and Depression Scale in a polytrauma clinic. Journal of rehabilitation research and development Boxley, L., Flaherty, J. M., Spencer, R. J., Drag, L. L., Pangilinan, P. H., Bieliauskas, L. A. 2016; 53 (6): 873-880

Abstract

The Hospital Anxiety and Depression Scale (HADS) is a brief self-report measure of anxiety and depression symptoms. This study examined the internal consistency and factor structure of the HADS among Veterans in a polytrauma/traumatic brain injury clinic. The sample consisted of 312 Veterans. A confirmatory factor analysis of the depression and anxiety subscales showed, not surprisingly, that the two factors were highly correlated (r = 0.7). Goodness of fit statistics for the two-factor model were acceptable (root mean square error of approximation = 0.06, comparative fit index = 0.94). The HADS demonstrated very good reliability overall (alpha = 0.89) and for the individual subscales (alpha = 0.84). This study supports the use of the HADS as a screen for depression and anxiety in the assessment of mild traumatic brain injury in a Veteran population.
