The a priori hypothesis was: the ISYQOL-PL questionnaire is reliable and appropriate for adolescents with a spinal deformity. Fifty-six adolescents (mean age 13.8 \u00b1 1.9) with idiopathic scoliosis (AIS) with a mean Cobb angle 29.1 (\u00b19.7) and two with Scheuermann juvenile kyphosis (SJK) with a kyphosis angle 67.5 (\u00b117.7) degrees were enrolled. All patients had been wearing a corrective TLSO brace for an average duration of 2.3 (\u00b11.8) years. The Institutional Review Board approved the study. The cross-cultural adaptation of the ISYQOL-PL was performed following the guidelines set up by the International Quality of Life Assessment Project. The reliability was assessed using internal consistency (the Cronbach\u2019s alpha coefficient) and test\u2013retest reliability (intraclass correlation coefficient ICC2.1, CI = 95%); moreover, floor and ceiling effects were calculated. The internal consistency was satisfactory (Cronbach\u2019s alpha coefficient 0.8). The test\u2013retest revealed high reliability with the value of ICC2.1 for the entire group 0.90, CI (0.84 to 0.94). There was neither floor nor ceiling effect for the ISYQOL-PL overall score. The ISYQOL-PL is reliable and can be used in adolescents with spinal deformity.<\/jats:p>","DOI":"10.3390\/jcm10102081","type":"journal-article","created":{"date-parts":[[2021,5,12]],"date-time":"2021-05-12T10:59:12Z","timestamp":1620817152000},"page":"2081","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Polish Adaptation of the Italian Spine Youth Quality of Life Questionnaire"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9106-8016","authenticated-orcid":false,"given":"Edyta","family":"Kinel","sequence":"first","affiliation":[{"name":"Department of Rehabilitation, University of Medical Sciences in Poznan, 61-545 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0213-2210","authenticated-orcid":false,"given":"Krzysztof","family":"Korbel","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, University of Medical Sciences in Poznan, 61-545 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piotr","family":"Janusz","sequence":"additional","affiliation":[{"name":"Department of Spine Disorders and Pediatric Orthopedics, University of Medical Sciences in Poznan, 61-545 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1469-9388","authenticated-orcid":false,"given":"Mateusz","family":"Kozinoga","sequence":"additional","affiliation":[{"name":"Department of Spine Disorders and Pediatric Orthopedics, University of Medical Sciences in Poznan, 61-545 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dariusz","family":"Czaprowski","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy, University of Medical Sciences in Poznan, 61-545 Poznan, Poland"},{"name":"Department of Health Sciences, Olsztyn University, Bydgoska 33, 10-243 Olsztyn, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"Kotwicki","sequence":"additional","affiliation":[{"name":"Department of Spine Disorders and Pediatric Orthopedics, University of Medical Sciences in Poznan, 61-545 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1186\/1748-7161-5-21","article-title":"Determination of quality of life in adolescents with idiopathic scoliosis subjected to conservative treatment","volume":"5","author":"Aulisa","year":"2010","journal-title":"Scoliosis"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"861","DOI":"10.1097\/00007632-200404150-00008","article-title":"The influence of spine and trunk deformity on preoperative idiopathic scoliosis patients\u2019 health-related quality of life questionnaire responses","volume":"29","author":"Asher","year":"2004","journal-title":"Spine"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1310","DOI":"10.1097\/01.brs.0000163885.12834.ca","article-title":"Construction and Validation of the Scoliosis Quality of Life Index in Adolescent Idiopathic Scoliosis","volume":"30","author":"Feise","year":"2005","journal-title":"Spine"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1186\/1748-7161-1-7","article-title":"Development and preliminary validation of Brace Questionnaire (BrQ): A new instrument for measuring quality of life of brace treated scoliotics","volume":"1","author":"Vasiliadis","year":"2006","journal-title":"Scoliosis"},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"1603","DOI":"10.1007\/s00586-012-2188-0","article-title":"Polish validation of Brace Questionnaire","volume":"21","author":"Kinel","year":"2012","journal-title":"Eur.
