Psychometric qualities of the Dutch language version of the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH-DLV).

This study evaluated the psychometric qualities (internal consistency, test-retest reliability, and concurrent validity) of the Dutch language version of the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH-DLV) in patients (n = 50) with a variety of unilateral disorders of the upper limb. All patients completed the Canadian Occupational Performance Measure (COPM) and the DASH-DLV before receiving occupational therapy. After therapy, patients again filled in the DASH-DLV.
