Qualidade de vida e saúde bucal em crian?as - parte II: vers?o brasileira do Child Perceptions Questionnaire

摘要

The Child Perceptions Questionnaire (CPQ11-14) is a self-administered instrument for the assessment of oral health-related quality of life in children. The objective of this study was to translate and adapt the questionnaire for use in Brazil. The questionnaire was translated from the English original into Brazilian Portuguese using the back-translation method (English/Portuguese/English), followed by evaluation by the review committee and cultural adaptation in a sample of 20 children. Eleven- to fourteen-year-old children did not understand some questions of the questionnaire. Initially, questions 4 and 11 showed an index of "incomprehensibility" in excess of 15%. The necessary cultural adapations were made and the third Portuguese version of CPQ11-14 was self-applied on a new sample of 20 children. Only one question (40) was misunderstood and modified. The fourth Portuguese version was considered adequate by more than 95% of the children evaluated. The Portuguese version of CPQ11-14 is a useful instrument for assessing oral health-related quality of life in Brazilian children.
