Validation of a Chinese version of the child perception questionnaire / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To translate the original English version of the child perception questionnaire (CPQ(11-14)) into Chinese version and to test the psychometric properties of the Chinese version in order to use among the Chinese children.</p><p><b>METHODS</b>The original English version of CPQ(11-14) was translated into Chinese, and pre-tested and cross-cultural 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.</p><p><b>RESULTS</b>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 CPQ(11-14) score (P<0.0005). Significant relationships were identified between caries status and CPQ(11-14) scores (P<0.001), and between malocclusion and CPQ(11-14) scores in middle-school-group (P<0.05).</p><p><b>CONCLUSION</b>The translated Chinese version of CPQ(11-14) 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.</p>
