Purpose: The study was planned to develop and validate a novel middle childhood oral health impact scale (MCOHIS) for 6- to 9-year-old children in India. Methodology: A cross-sectional study design was employed to develop and validate MCOHIS in the sequential phases. A panel of ten pediatric dentists evaluated a pool of 36 items corresponding to the oral health-related quality of life (OHRQoL) of children. MCOHIS with 20 items under five domains was formulated and content validation was done. Cohen's kappa statistics was employed to measure the concordance between the child's self-report and the caregiver's proxy report. Concurrent validation was done among 130 participants from 13 districts of Tamil Nadu state, India. Discriminant validity was checked among another sample of 60 participants. Internal consistency and test-retest reliability of MCOHIS were assessed using Cronbach's alpha and Kappa statistics respectively. Results: MCOHIS had adequate content validation with Scale Level Content Validity Index / Average score of 0.94 for relevance. There was a statistically significant inter-rater reliability observed between the child's self-report and caregivers' proxy report in all items with a moderate to substantial agreement. Concurrent validation showed a statistically significant positive correlation with a Rho value of 0.712. There was a statistically significant difference noted in overall discriminant validity (P < 0.001). Acceptable internal consistency reliability was observed with Cronbach's alpha value of 0.75. Test-retest reliability showed a high stability coefficient of 0.98. Conclusions: MCOHIS was found to be a valid and reliable age-specific tool for assessing the OHRQoL of Indian children aged 6–9 years.
