The objective of this study was to explore the internal consistency, factor structure, and floor\/ceiling effect of QuickDASH among patients with carpal tunnel syndrome. This was a retrospective cross-sectional register-based study among 1597 patients with electromyography-confirmed carpal tunnel syndrome. The internal consistency was assessed using Cronbach\u2019s <jats:italic toggle=\"yes\">\u03b1<\/jats:italic>. Exploratory factor analysis was used to evaluate factor structure. Of 1597 respondents, 896 (56%) were women. The average age was 55.0 (16.3) years. The mean QuickDASH score was 38 (23.2) points. QuickDASH demonstrated an excellent internal consistency with <jats:italic toggle=\"yes\">\u03b1<\/jats:italic> of 0.92 (95% confidence interval: 0.92\u20130.93). Exploratory factor analysis demonstrated unidimensionality. Item loadings were moderate to substantial for all 11 items, varying from 0.55 to 0.83. A significant floor effect was observed for nine of 11 items varying from 20 to 51%. A ceiling effect was observed for one item (#6 \u2018recreational activities\u2019). Despite its significant floor effect, QuickDASH can be recommended as a valid and reliable scale to assess the severity of disability caused by carpal tunnel syndrome.<\/jats:p>","DOI":"10.1097\/mrr.0000000000000673","type":"journal-article","created":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T05:00:16Z","timestamp":1751259616000},"page":"180-186","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Internal consistency, factor structure, and floor\/ceiling effect of Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire among people with carpal tunnel syndrome"],"prefix":"10.1097","volume":"48","author":[{"given":"Annika","family":"Miikkulainen","sequence":"first","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Turku University Hospital and University of Turku, Turku"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikhail","family":"Saltychev","sequence":"additional","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Turku University Hospital and University of Turku, Turku"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Widbom-Kolhanen","sequence":"additional","affiliation":[{"name":"Department of Surgery, Satasairaala Hospital, Pori"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juhani","family":"Juhola","sequence":"additional","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Turku University Hospital and University of Turku, Turku"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanna-Stiina","family":"Taskinen","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Turku University Hospital and University of Turku, Turku, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,6,30]]},"reference":[{"key":"R1-20250729","doi-asserted-by":"crossref","first-page":"2013","DOI":"10.1056\/NEJM199312303292707","article-title":"Entrapment neuropathies of the upper extremities.","volume":"329","author":"Dawson","year":"1993","journal-title":"N Engl J Med"},{"key":"R2-20250729","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1001\/jama.282.2.153","article-title":"Prevalence of carpal tunnel syndrome in a general population.","volume":"282","author":"Atroshi","year":"1999","journal-title":"JAMA"},{"key":"R3-20250729","doi-asserted-by":"crossref","first-page":"602","DOI":"10.1002\/(SICI)1097-0274(199606)29:6<602::AID-AJIM4>3.0.CO;2-L","article-title":"Development of an upper extremity outcome measure: the DASH (disabilities of the arm, shoulder and hand) [corrected].
