The Greek Version of the Child Oral Health Impact Profile‐Short Form 19: Translation, Cultural Adaptation and Psychometric Properties

Abstract

ABSTRACT Objectives Tools evaluating how oral health affects the quality of life in children serve as valuable patient‐related outcome measures (PROMs). This study aimed to develop a culturally adapted Greek version of the Child Oral Health Impact Profile‐Short Form 19 (COHIP‐SF 19) and assess its psychometric properties. Methods Bilingual translation and cultural adaptation using cognitive interviews with 15 children aged 8–15 years were conducted to develop the final Greek version. Psychometric testing of the Gr‐COHIP‐SF 19 was performed in a field study of 196 children and included confirmatory factor analysis, face validity, internal consistency and test–retest reliability. Face validity was additionally evaluated by 50 dentists. Results Face validity was excellent, endorsed by 93.9% of children and 100% of dentists. Confirmatory factor analysis findings indicated a marginal model fit, providing partial support for the original three‐factor structural model. Internal consistency was high for the total scale (Cronbach's alpha: 0.84) and the Socio‐emotional Well‐being subscale (Cronbach's alpha: 0.84), but marginal for the Oral‐Health and the Functional Well‐being subscales (Cronbach's alpha: 0.62–0.64). Test–retest reliability (ICC = 0.80; 95% CI 0.65–0.88) was satisfactory. Conclusions The total Gr‐COHIP‐SF 19 demonstrates satisfactory validity and reliability for evaluating oral health‐related quality of life in children and young adolescents. Although individual subscale scores should be interpreted with caution, the total tool can serve as a useful PROM to support patient‐centred dental care and research in Greek‐speaking children and young adolescents.
