Abstract:

Objective To translate the original English version of the child perception questionnaire（CPQ11- 14）into Chinese version and to test the psychometric properties of the Chinese version in order to use among the Chinese children. Methods The original English version of CPQ11- 14 was translated into Chinese, and pre- tested and crosscultural adapted. Subsequently, the Chinese version with a general questionnaire was administered to 218 children aged from 11 to 14, clinical data on caries status and malocclusion were collected through oral health examination. Results Test- retest reliability was substantial（r=0.82, P<0.001）. Cronbach′s alpha of the translated scale was 0.79. The 16 items were divided into five domains by factor analysis. There was certain logical relation between the items in the same domains. There was highly significant association between perceived oral health status, perceived impact to quality of life by oral health and CPQ11-14 score（P<0.000 5）. Significant relationships were identified between caries status and CPQ11- 14 scores（P<0.001）, and between malocclusion and CPQ11- 14 scores in middle- school- group（P<0.05）. Conclusion The translated Chinese version of CPQ11-14 demonstrated good reliability and validity. Its good psychometric properties provide the theoretical evidence for further use in Chinese population. It is available for use by researchers in oral health related quality of life studies in Chinese children.
