title: Validation of a French version of the Child-OIDP index.
abstract: The Child-OIDP index is an indicator of oral health-related quality of life, which has been validated among 12-yr-old children in Thailand. The aim of this study was to assess the reliability, validity, and applicability of this questionnaire among French children. After translation and cultural adaptation, the Child-OIDP was tested on 414 10-yr-old children in France. The children completed the Child-OIDP in face-to-face interviews, were clinically examined, and answered questions evaluating their global self-rated oral health. Parents filled in a questionnaire concerning their socio-demographic background. An oral impact on daily life was reported by 73% of the children. The mean Child-OIDP score was 6.32 [standard deviation (SD) 8.22] and the median was 3.33. The internal reliability was confirmed with a Cronbach's alpha of 0.57. The retest procedure (n = 62) showed a satisfactory reproducibility (r = 0.81, kappa = 0.75). The index was shown to be a valid instrument. Construct validity was satisfactory as the Child-OIDP score increased when the children's perceived oral health decreased. The Child-OIDP score was able to discriminate between different socio-demographic groupings and varied according to dental status. This study showed that the Child-OIDP is applicable for use among children in France. It has promising psychometric properties but further research is required to evaluate its sensitivity to change.
