Abstract

|
Objectives.The purpose of this study was to validate a Korean version of the Oral Impacts on Daily Performances for children (COIDP) inventory.
Methods.A total of 324 fifth-grade schoolchildren was selected by cluster sampling. A questionnaire including items on COIDP was completed and information on dental caries was collected. Statistical analysis was performed by non-parametric methods.
Results.Internal reliability and test-retest reliability were assessed as reasonable with the Chronbach’s alpha of 0.67 and intraclass coefficient of 0.74, respectively. The concurrent validity was verified by the significant association of COIDP score to self-reported oral health, satisfaction about oral health and appearance. The discriminative validity was confirmed by the ability in distinguishing groups with and without dental treatment, dental problems, and decayed teeth. An exploratory factor analysis divided the eight COIDP items into three factors.
Conclusions.The Korean version of COIDP is a valid and reliable inventory to assess oral health-related quality of life among Korean children.
