Validity and Reliability of Vietnamese Child Oral Health Impact Profile
Objectives: The Child Oral Health Impact Profile (COHIP) is a tool to evaluate the impact of oral health on quality of life. However, there was no Vietnamese standardized COHIP version. The purpose of this study was to assess the validity and reliability of the Vietnamese COHIP questionnaire with 38 items (COHIP-VIET) among 12-to-15-year-old children in Ho Chi Minh city, Vietnam.
Methods: The original English version of COHIP was translated into Vietnamese (COHIP-VIET) and then backward-translated into English by two local dentists with certified English level. The COHIP-VIET was reviewed by a panel of five experts and then one pilot study was conducted among thirty 12-year-old children before the main survey. A cross-sectional study was performed among 853 children from 12 to 15 years old in Ho Chi Minh city during April, 2021. They responsed the COHIP-VIET questionnnaire with instruction from trained interviewers. Twenty-five percents of them was randomly selected to respond again after two weeks. The validity and reliability of COHIP-VIET were evaluated using Intraclass Correlation Coefficients (ICC) and Cronbach’s alpha coefficients.
Results: The COHIP-VIET with 38 items was constructed. The COHIP score among 12-15 year-old children ranged from 46 to 153 (mean ± SD: 110.41±16.08). The general ICC was 0.884 (for Oral health, Functional well-being, Emotional/ Social well-being, School environment and Self-image were 0.854, 0.844, 0.880, 0.730, 0.806, respectively). The Cronbach’s alpha was 0.88 (Oral health = 0.69; Functional well-being = 0.68; Emotional/ Social well-being = 0.86; School environment = 0.63; Self-image = 0.72).
Conclusions: The Vietnamese 38-item COHIP showed high validity and reliability for 12-to-15-year-old children in Ho Chi Minh city, Vietnam. The Child COHIP-VIET could be used as an Oral Health Related Quality of Life tool among Vietnamese children.
