Alidity and reliability of child oral health impact profile among Vietnamese children from 12 to 15 years old

Abstract

Background: Child Oral Health Impact Profile (COHIP) is a tool to evaluate the impact of oral health related to quality of life. However, there is no Vietnamese standardized COHIP version in Vietnam. This study assessed the validity and reliability of the Vietnamese version of COHIP questionnaire (COHIP-VIET) among Vietnamese children from 12 to 15 years old. Methods: A cross-sectional descriptive study was performed in 853 children from 12 to 15 years old in Ho Chi Minh city from 5/2020 to 4/2021. The original English version of COHIP was translated into Vietnamese (COHIP-VIET) and then backward-translated into English by two dental specialists with certified English level. The COHIP-VIET was reviewed by a specialist committee and was pilot-studied in 30 children from 12-15 years old before performing a main study. The COHIP-VIET was retested with 25% of the sample after two weeks. The Intraclass Correlation Coefficients (ICC) and Cronbach’s alpha coefficients were utilized in this study. Results: The COHIP-VIET was constructed in this study. COHIP score of 12-15 year-old children ranged from 46 to 153. The COHIP-VIET had high reliability with ICC= 0.884 (95% CI= 0.843 – 0.914) and Cronbach’s alpha= 0.88. Conclusions: The COHIP-VIET has high validity and reliability. This questionaire can be used in self-evaluation oral health related quality of life among Vietnamese children from 12 to 15 years old.
