Abstract
OBJECTIVES: This study aimed to establish a Chinese version of the Child Perceptions Questionnaire for children aged 8-10 years (CPQ(8-10)) and evaluate its reliability and validity for a comprehensive and reliable assessment of oral health-related quality of life in children. METHODS: The Chinese CPQ(8-10) was formed through translation, reverse translation, and cross-cultural adaption according to international standard procedures. It was used to evaluate the children's oral health-related quality of life to assess the reliability and validity of the scale. RESULTS: A total of 446 children received the survey, and 405 valid questionnaires were obtained. Cronbach's a for the full scale was 0.87, and the intraclass correlation coefficient for the total scale was 0.88. The CPQ(8-10) score was significantly correlated with the score of two global questions (P<0.01). The dental caries group had the highest score of the full scale, followed by the malocclusion group; the healthy group had the lowest score (P<0.01). CONCLUSIONS: The Chinese version of CPQ(8-10) demonstrates great reliability and validity and provides a theoretical basis for its application in Chinese children aged 8-10 years.
