We translated and culturally adapted these tools for use in Chile. This study evaluated internal consistency and test\u2013retest reliability for the IT, described reported symptoms with the ST, and explored changes over time.\n\nMethods The first phase, previously published, involved translation and cultural adaptation. The second phase included 28 patients with persistent COVID-19 symptoms; 20 completed a second assessment. The IT assesses impact using six items, each scored 0\u201310 (total 0\u201360). The ST lists 53 symptoms across ten categories. Internal consistency of the IT was assessed using Cronbach\u2019s alpha and item-consistency indicators. Test\u2013retest reliability was evaluated using the intraclass correlation coefficient (ICC, 95% CI) and a Bland\u2013Altman analysis. ST responses were summarized with absolute and relative frequencies and confidence intervals.\n\nResults The IT showed excellent internal consistency (Cronbach\u2019s alpha 0.945; 95% CI 0.906\u20130.971). Test\u2013retest reliability was acceptable (ICC 0.72; 95% CI 0.43\u20130.88), with minimal bias in the Bland\u2013Altman plot. General, neurological, thoracic, and ear\u2013nose\u2013throat symptoms were the most frequent. Participants reported a mean of 19 symptoms, with no significant differences between visits.\n\nConclusions The adapted tools demonstrated acceptable psychometric properties and appear suitable for use in Chile. Symptom reporting was extensive, underscoring the need for larger studies to confirm these findings.<\/jats:p>","DOI":"10.5867\/medwave.2026.02.3205","type":"journal-article","created":{"date-parts":[[2026,3,13]],"date-time":"2026-03-13T18:41:45Z","timestamp":1773427305000},"page":"e3205-e3205","source":"Crossref","is-referenced-by-count":0,"title":["Validation of the cultural adaptation of the \"Long Coronavirus Disease (COVID) Symptom and Impact Tools\" for the Chilean population"],"prefix":"10.5867","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5715-9755","authenticated-orcid":false,"given":"Vivienne C.","family":"Bachelet","sequence":"first","affiliation":[{"name":"Escuela de Medicina, Facultad de Ciencias M\u00e9dicas, Universidad de Santiago de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9647-3061","authenticated-orcid":false,"given":"Rosa","family":"Jim\u00e9nez-Paneque","sequence":"additional","affiliation":[{"name":"Facultad de Medicina, Universidad Diego Portales, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0722-4624","authenticated-orcid":false,"given":"Patricio","family":"Gomol\u00e1n","sequence":"additional","affiliation":[{"name":"Escuela de Medicina, Facultad de Ciencias M\u00e9dicas, Universidad de Santiago de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6996-3695","authenticated-orcid":false,"given":"Ignacio","family":"Silva-Ayarza","sequence":"additional","affiliation":[{"name":"Escuela de Medicina, Facultad de Ciencias M\u00e9dicas, Universidad de Santiago de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mercedes","family":"L\u00f3pez Nitsche","sequence":"additional","affiliation":[{"name":"Programa de Inmunolog\u00eda, Instituto de Ciencias Biom\u00e9dicas (ICBM), Facultad de Medicina, Universidad de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3028-109X","authenticated-orcid":false,"given":"Catalina O.","family":"Andrades","sequence":"additional","affiliation":[{"name":"Escuela de Medicina, Facultad de Ciencias M\u00e9dicas, Universidad de Santiago de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7591-8653","authenticated-orcid":false,"given":"Bel\u00e9n","family":"Carroza","sequence":"additional","affiliation":[{"name":"Escuela de Medicina, Facultad de Ciencias M\u00e9dicas, Universidad de Santiago de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0337-2067","authenticated-orcid":false,"given":"Bruno","family":"Morgado","sequence":"additional","affiliation":[{"name":"Escuela de Medicina, Facultad de Ciencias M\u00e9dicas, Universidad de Santiago de Chile, Santiago, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3888","published-online":{"date-parts":[[2026,3,13]]},"container-title":["Medwave"],"original-title":[],"deposited":{"date-parts":[[2026,3,13]],"date-time":"2026-03-13T18:41:46Z","timestamp":1773427306000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medwave.cl\/investigacion\/estudios\/3205.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,13]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2026,3,13]]}},"URL":"https:\/\/doi.org\/10.5867\/medwave.2026.02.3205","relation":{},"ISSN":["0717-6384"],"issn-type":[{"value":"0717-6384","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3,13]]}}}
