there is a growing need for valid, reliable and standardized patient-rated outcome measures for use in clinical practice and research. The PRWHE is a self-reported assessment of hand-related disorders that measures pain and functional difficulties in activities of daily living. The purpose of this study was to: 1) translate and cross-culturally adapt the PRWHE into Danish and, 2) assess the reliability and construct validity of the Danish version in patients with hand-related disorders. Methods: The PRWHE has been translated and cross-culturally adapted into Danish using the dual-panel approach. A total of 97 patients with diverse hand-related disorders and a mean age of 52.6 (sd 15.2) participated in the psychometric testing. They were assessed on two occasions. Reliability was assessed using the intraclass correlation coefficient (ICC2.1) to assess test-retest, Cronbach's alpha (CA) assessing internal consistency and a Bland-Altman plot assessing measurement error. Construct validity was investigated by evaluating the relationship between the Danish PRWHE (PRWHE-DK) and the Danish validated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH). 2 Results: Psychometric testing demonstrated an excellent test-retest reliability (ICC2.
