Cross-cultural adaptation of the disabilities of the arm, shoulder, and hand (DASH) questionnaire into Hungarian and investigation of its validity in patients with systemic sclerosis.

Abstract

The Hungarian version of the DASH and QuickDASH demonstrated equivalent reproducibility, internal consistency and validity to the originals. The strong correlations of the DASH and QuickDASH with the HAQ-DI, and with the physical dimensions of the SF-36 show that the disability of the patient with SSc is predominantly caused by the functional impairment of the upper limb. Because both questionnaires were valuable tools for measuring upper extremity function and joint damage in SSc patients, we recommend the shorter and simpler QuickDASH for everyday clinical use.
