The scale consists of two parts, CarerQol-7D, which measures the effects of informal care using two positive and five negative domains, and CarerQol-VAS, which measures happiness on a visual analog scale. Methods: In the present work, we conducted a systematic review of the instrument since its development in 2006, followed by a (convergent, clinical, and discriminative) validity analysis and a meta-analysis of the reliability of generalizing CarerQol. A total of 54 articles that used CarerQol were identified. Results: The instrument was found to have good convergent, clinical, and discriminant validity, although the average reliability coefficient was 0.67 (95% CI [0.56, 0.75]) for Cronbach\u2019s alpha coefficients and 0.62 (95% CI [0.04, 0.89]) for test\u2013retest reliability coefficients, with a high degree of heterogeneity between the coefficients. Conclusions: According to the psychometric theory, CarerQol is a reliable instrument and can be used for exploratory purposes in the field of research, although it should be used with caution when making decisions in clinical practice.<\/jats:p>","DOI":"10.3390\/jcm14061916","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T10:45:06Z","timestamp":1741776306000},"page":"1916","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The CarerQol Instrument: A Systematic Review, Validity Analysis, and Generalization Reliability Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2393-6499","authenticated-orcid":false,"given":"Elena","family":"Cejalvo","sequence":"first","affiliation":[{"name":"Department of Basic Psychology, Faculty of Psychology and Speech Therapy, University of Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3305-2996","authenticated-orcid":false,"given":"Manuel","family":"Mart\u00ed-Vilar","sequence":"additional","affiliation":[{"name":"Department of Basic Psychology, Faculty of Psychology and Speech Therapy, University of Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1280-9312","authenticated-orcid":false,"given":"J\u00falia","family":"Gisbert-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Department of Behavioural Sciences Methodology, Faculty of Psychology and Speech Therapy, University of Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4706-690X","authenticated-orcid":false,"given":"Laura","family":"Badenes-Ribera","sequence":"additional","affiliation":[{"name":"Department of Behavioural Sciences Methodology, Faculty of Psychology and Speech Therapy, University of Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,12]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2022).
