Cross-cultural adaptation and validation of hindi version of child oral impacts on daily performance index

Abstract

Introduction: Oral diseases may have an impact on quality of life (QoL) and the oral health-related quality of life (OHRQoL). As compared to clinical measures which are unable to provide a complete picture, OHRQoL indices quantify the oral health impact on overall health. Worldwide indices have been developed to measure the OHRQoL in children but none can be applicable in Indian context. Aim: The aim of the study was cross-cultural adaptation and psychometric analysis of Hindi version of child oral impacts on daily performance (C-OIDP) index. Materials and methods: Translation and back translation were done for index using prescribed guidelines for cross-cultural adaptation. A pilot study was conducted in 32 children and required modifications were done. The final Hindi version was tested for reliability and validity on a convenience sample of 64 children aged 11–14 years selected from public schools in Delhi. The psychometric properties of the Hindi version were tested for face, content, construct validity along with internal consistency, and test–retest reliability. Results: The mean age of the final sample (n = 64) was 13.02 ± 0.93 years with boys (51.6%) and girls (48.4%). The mean C-OIDP score was 8.8 ± 7.8. Significant association was obtained when C-OIDP was compared with self-perceived oral health. Interitem correlation ranged from −0.008 to 0.45. Kappa for categories of child OIDP ranged from 0.711 to 1.00 and intraclass correlation coefficient was 0.91. Conclusion: The Hindi version of C-OIDP is a valid and reliable tool to measure OHRQoL in Hindi-speaking children in India.
