ObjectiveThis study aimed to establish a Chinese version of the Child Perceptions Questionnaire for children aged 8-10 years (CPQ8-10) and evaluate its reliability and validity for a comprehensive and reliable assessment of oral health-related quality of life in children.
MethodsThe Chinese CPQ8-10was 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.
ResultsA 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 CPQ8-10score 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).
ConclusionThe Chinese version of CPQ8-10demonstrates great reliability and validity and provides a theoretical basis for its application in Chinese children aged 8-10 years.
