Disability in depression and back pain

Chwastiak, Lydia A., Von Korff, Michael·2003·Journal of Clinical Epidemiology

Abstract

The World Health Organization Disability Assessment Schedule (WHO DAS II) is a new measure of disability based on the ICIDH-2 model of functioning and disability. This study evaluates the measurement properties of the WHO DAS II in two disorders commonly encountered in the primary care setting. Seventy-three patients with depression and 76 patients with back pain were interviewed at baseline and after 3 months of usual primary care. Internal validity, convergent validity, and responsiveness to change of the WHO DAS II were evaluated. The WHO DAS II had excellent internal validity and convergent validity in the primary care setting. The responsiveness to change of the WHO DAS II was comparable to that of the SF-36. The WHO DAS II appears to be a useful health status instrument for measuring the disability associated with both physical and mental disorders in the primary care setting. This instrument facilitates the use of the ICIDH-2 as a framework for evaluating activity limitations and participation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
