Concerns were activity-dependent in each category (\u03c1 &lt; 1x10\n                  <jats:sup>-100<\/jats:sup>\n                  ). Reliability analysis and principal components analysis were used to reduce the battery to the 51-item Changed Hand Usage Concerns inventory, which encompasses everyday tasks and concerns about physical and emotional consequences of using the non-preferred hand in those tasks.\nConclusions: Concerns about emotional vs. physical consequences of non-preferred hand use reflect coherent and internally consistent categories The Changed Hand Usage Concerns inventory allows assessment of psychosocial concerns about usage of the non-preferred hand for future attempts to manipulate hand usage via rehabilitation in patients with unilateral or asymmetric impairment.\n                <\/jats:p>","DOI":"10.64898\/2026.03.26.26347326","type":"posted-content","created":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T17:55:32Z","timestamp":1775066132000},"source":"Crossref","is-referenced-by-count":0,"title":["Development of an Inventory to Identify Psychosocial Factors Influencing Hand Usage: the CHUC"],"prefix":"10.64898","author":[{"given":"T\u00e9a","family":"Soberano","sequence":"first","affiliation":[{"name":"Washington University School of Medicine;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3733-6638","authenticated-orcid":false,"given":"Chih-Hung","family":"Chang","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8293-6034","authenticated-orcid":false,"given":"Alexandre J","family":"Marcori","sequence":"additional","affiliation":[{"name":"Universidade Estadual de Londrina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5467-8384","authenticated-orcid":false,"given":"Benjamin A","family":"Philip","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.64898\/2026.03.26.26347326","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T17:55:32Z","timestamp":1775066132000},"score":1,"resource":{"primary":{"URL":"http:\/\/medrxiv.org\/lookup\/doi\/10.64898\/2026.03.26.26347326"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,1]]},"references-count":0,"URL":"https:\/\/doi.org\/10.64898\/2026.03.26.26347326","relation":{},"subject":[],"published":{"date-parts":[[2026,4,1]]},"subtype":"preprint"}}
