The validation was performed suppling the QoR-15I to 3,784 patients enrolled in two parallel stepped wedge cluster randomised trials (ERAS Colon-rectum Piemonte; ERAS Gyneco Piemonte). The factor structure and its invariance between types of surgery was tested using confirmatory bifactor model and multi-group analysis. Comparative fit index (CFI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR) fit indices and their changes between nested models were used to assess the factor structure and the invariance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The bifactor model showed good fit (RMSEA\u2009=\u20090.049, CFI =0.957, SRMR\u2009=\u20090.036) and provided a general recovery factor and two specific factors for physical and mental recovery. Eighty-four percent of the common variance is attributable to the general factor, and thus the QoR-15I is sufficiently \u2018one-dimensional\u2019 with an adequate reliability (\u03c9<jats:sub>h<\/jats:sub> =\u20090.70). The \u03c9s values for the physical and mental recovery factors were 0.01 and 0.13, respectively. Multigroup analysis supported configural (RMSEA\u2009=\u20090.053, CFI\u2009=\u20090.950, SRMR\u2009=\u20090.035) and metric invariance (\u0394RMSEA\u2009=\u2009-0.004; \u0394CFI\u2009=\u2009-0.002; \u0394SRMR\u2009=\u20090.014), whereas the intercept constraint was removed from item 15 to obtain partial scalar invariance (\u0394RMSEA\u2009=\u20090.002; \u0394CFI\u2009=\u20090.007; \u0394SRMR\u2009=\u20090.004). Construct validity was supported by a negative association of QoR-15I scores with all variables related to worse patient condition and more complex surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our results support the use of the QoR-15I as a valid, reliable, and clinically feasible tool for measuring the quality of recovery after surgery. The results of the confirmatory factor analyses suggest that a unique recovery score can be calculated and support measurement invariance of the QOR-15I across the two type of surgery, suggesting that the questionnaire has the same meaning and the same measurement parameters in colorectal and gynaecologic patients.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpsyg.2022.1096579","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T14:13:54Z","timestamp":1675260834000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Factor structure of post-operative quality of recovery questionnaire (QoR-15): An Italian adaptation and validation"],"prefix":"10.3389","volume":"13","author":[{"given":"Rosalba","family":"Rosato","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valentina","family":"Palazzo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felice","family":"Borghi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Camanni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Puppo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena Maria","family":"Delpiano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Pellegrino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisa","family":"Piovano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessio","family":"Rizzo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monica","family":"Rolfo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Morino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco Ettore","family":"Allaix","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Testa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovannino","family":"Ciccone","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva","family":"Pagano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,2,1]]},"reference":[{"key":"ref1","volume-title":"Confirmatory factor analysis for applied research","author":"Brown","year":"2015"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"251","DOI":"10.1007\/s40271-015-0148-6","article-title":"Validation of the Chinese version of the quality of Recovery-15 score and its comparison with the post-operative quality recovery scale","volume":"9","author":"Bu","year":"2016","journal-title":"Patient"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"832","DOI":"10.1093\/bja\/aer094","article-title":"Effect of patient sex on general anaesthesia and recovery","volume":"106","author":"Buchanan","year":"2011","journal-title":"Br.
