Abstract:
OBJECTIVES: The purpose of this study was to develop a self-administered questionnaire survey to determine its validity and reliability as well as to improve the instructions for measurement of periodontal disease during oral examination for reliably calculating the prevalence of periodontal disease. METHODS: The data obtained was analyzed using SPSS 20.0 and the WINSTEPS program that employs the Rasch model to evaluate validity and reliability of the instrument. RESULTS: We developed a self-administered questionnaire survey consisting of 14 questions based on NHANES. We confirmed the reliability by testing and re-testing the questionnaire survey using selfadministered methods. The average Kappa index obtained was 0.73, which indicated a relatively high reliability. CONCLUSIONS: Reliability and validity of the self-administered assessment tool for periodontal disease developed for the local situation/circumstances of Korea is suitable to be applied for oral examination of a large population. Moreover, the questionnaire survey for periodontal disease could be used to acquire data for constructing a database for oral health policy development.
