Background:
The Child Oral Health Impact Profile - Preschool version (COHIP-PS) is the first validated questionnaire designed to assess the oral health-related quality of life (OHRQoL) of preschool children with varying oral health-related conditions.
Aim:
To cross-culturally adapt the original version of COHIP-PS into Chinese and to assess the psychometric properties of a web-based version of the COHIP-PS (eCOHIP-PS/C).
Design:
The eCOHIP-PS/C was first created using current guidelines. Then, the eCOHIP-PS/C was administered to caregivers having children 2-5 years old. The reliability of the eCOHIP-PS/C was estimated using Cronbach's alpha and the intraclass correlation coefficients (ICC). Cross-cultural validity and convergent validity were also investigated.
Results:
The study included 260 children (mean age 4.3 years). Cronbach's alpha of eCOHIP-PS/C was 0.903 and the ICC of the scale was 0.862. Confirmatory factor analysis (CFA) demonstrated that a four-component model was the best solution for the eCOHIP-PS/C. The fit indices were as follows: χ2 /df = 2.176, TLI = 0.942, CFI = 0.946, GFI = 0.927, and RMSEA = 0.075. In addition, a good relationship was found between the eCOHIP-PS/C and the global oral health question.
Conclusion:
The eCOHIP-PS/C is a reliable and valid tool for assessing the OHRQoL among Chinese preschool children.
