Validity and reliability of the Turkish version of the Child Perceptions Questionnaire 8-10.

Abstract

A reliable measurement tool is needed to gain more knowledge about Turkish children's oral health status that affects the quality of life. To develop a translated version of CPQ8-10 into Turkish language and evaluate its reliability, validity, and reproducibility. The intra-class correlation coefficient (ICC) was used for the test-retest reliability in the 50 children. For the internal consistency, 418 children aged 8-10years were evaluated using Cronbach's alpha Coefficient. Construct validity and discriminant validity were calculated using Spearman's correlation analysis, and exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was also employed. The mean CPQ8-10 score was 13.3±9.2. The translated Turkish version of CPQ8-10 showed high test-retest reliability (ICC=0.90) and internal consistency (Cronbach's alpha=0.82). A statistically significant correlation was observed between the scores of the CPQ8-10 and oral health and overall well-being, which revealed good construct validity (r=0.50; P<.001 and r=0.47; P<.001, respectively). Seven factors identified from EFA were statistically verified using CFA. Discriminant validity was supported by significant differences between CPQ and OHIS scores (P<.001). The translated version of CPQ8-10 to the Turkish language is reliable, valid, and reproducible for use in the Turkish culture in this age group.
