Multicenter Study
Psychometric properties of the WHODASII in rehabilitation patients.
To evaluate function and disability, the WHO has developed the WHO Disability Assessment Schedule II (WHODASII), an instrument arising from the same conceptual basis as the International Classification of Functioning, Disability, and Health (ICF). ⋯ The WHODAS II (German version) is a useful instrument for measuring functioning and disability in patients with musculoskeletal diseases, internal diseases, stroke, breast cancer, and depressive disorder. The results of this study support the reliability, validity, dimensionality, and responsiveness of the German version of the WHODASII. However, the reproducibility in test-retest samples of stable patients, as well as the question to what extent a summary score can be constructed, requires further investigation.
