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: χ 2 / 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.
