The original CPQ 8\u201310 was translated using a standardized forwardbackward method. A pre-test with 20 children guided cultural adaptations. The final version (CPQ\u2013GR8\u201310) was completed by 150 children aged 8\u201310 attending a university dental clinic. Reliability was assessed through internal consistency (Cronbach\u2019s \u03b1) and test\u2013retest reliability (intraclass correlation coefficient, ICC). Structural validity was evaluated using confirmatory and exploratory factor analyses. Construct validity was evaluated via correlations with self-rated oral health and clinical indices (CPI, OHI-S, DMFT\/dmft). Confirmatory factor analysis did not support the original four-factor structure. Exploratory factor analysis identified a proposed 21-item, twofactor solution. The CPQ\u2013GR8\u201310 showed very high internal consistency (\u03b1 = 0.98) and test\u2013retest reliability (ICC = 0.99\u20131.00). Convergent validity was supported by strong correlations with global oral health ratings (\u03c1 = 0.90\u20130.92). Concurrent validity was demonstrated through significant associations with clinical oral health indicators. The CPQ\u2013GR8\u201310 appears to be a reliable and valid tool for assessing oral health-related quality of life in Greek children. Although the original four-factor structure was not supported, a proposed 21-item, two-factor solution demonstrated excellent psychometric performance in this sample. Nonetheless, the consistently high reliability coefficients may reflect redundancy and sample homogeneity. The proposed 21-item, twofactor structure should be confirmed in larger, independent samples before modification of the original questionnaire can be recommended.<\/jats:p>","DOI":"10.1177\/0265539x261501332","type":"journal-article","created":{"date-parts":[[2026,10,24]],"date-time":"2026-10-24T07:22:33Z","timestamp":1792826553000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Validation of the Greek version of the Child perceptions questionnaire (CPQ\u2013GR8\u201310) for assessing oral health-related quality of life in 8\u201310-year-old children: A psychometric evaluation"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2172-4852","authenticated-orcid":false,"given":"Panayioula","family":"Lambrou","sequence":"first","affiliation":[{"name":"Aristotle University of Thessaloniki"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantinos","family":"Arapostathis","sequence":"additional","affiliation":[{"name":"Aristotle University of Thessaloniki"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasiliki","family":"Boka","sequence":"additional","affiliation":[{"name":"Aristotle University of Thessaloniki"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aristidis","family":"Arhakis","sequence":"additional","affiliation":[{"name":"Aristotle University of Thessaloniki"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,10,24]]},"reference":[{"key":"e_1_3_6_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1524-4733.2007.00292.x"},{"key":"e_1_3_6_3_1","doi-asserted-by":"publisher","DOI":"10.4317\/medoral.16.e430"},{"issue":"3","key":"e_1_3_6_4_1","first-page":"281","article-title":"Development of the World Health Organization (WHO) community periodontal index of treatment needs (CPITN)","volume":"32","author":"Ainamo J","year":"1982","unstructured":"Ainamo J, Barmes D, Beagrie G, et al.
