The Turkish version of Caries Impacts and Experiences Questionnaire for Children: Translation, reliability, and validity

Background Caries Impacts and Experiences Questionnaire for Children (CARIES‐QC) has been developed to assess the oral health‐related quality of life (OHRQoL) associated with caries. Aim This study aimed to evaluate the validity and reliability of the CARIES‐QC in the Turkish‐speaking population following its translation and adaptation into Turkish (CARIES‐QC/T). Design Two hundred and fifty children between the ages of 5 and 16 years who have active dental caries were included in the study and answered the Turkish‐translated and cross‐culturally adapted final version of CARIES‐QC/T. Test–retest reliability and internal consistency were used to examine the reliability of the CARIES‐QC/T. Factor structure of CARIES‐QC/T was analyzed using exploratory factor analysis (EFA), and convergent validity was determined. Results Cronbach's alpha and McDonald's ômega values were 0.907 and 0.908, respectively. For the CARIES‐QC/T scale, the intraclass correlation coefficient (ICC) value was 0.933, and polychoric correlations ranged from 0.390 to 0.794. The convergent validity of the items revealed a statistically significant correlation with the global question (rs = 0.821, p
