The current research aims to evaluate the reliability and validity of the Hindi Child Perception Questionnaire (CPQ11-14) in a child population of India. A randomly selected sample of children aged 11-14 years (n = 331) and their parents completed the Hindi translation of CPQ11-14 and the Parental-Caregiver Perceptions Questionnaire (P-CPQ), respectively, in this cross-sectional study. Children also provided a self-rating of oral health and were examined for dental caries. Exploratory Factor Analysis (EFA) was conducted to assess the dimensionality of the Hindi-CPQ11-14. Internal consistency and reliability on repeated administration were evaluated. Convergent and divergent validities were determined by estimating correlation coefficients between items and the hypothesised subscales. Concurrent validity was assessed using multiple linear regression analyses. The four factors extracted in EFA had a total variance of 38.5%, comprising 31 items. Cronbach's alpha for the internal consistency of the overall scale was 0.90; reliability on repeated administration was 0.92. All the Hindi CPQ11-14 items had an item-hypothesised subscale correlation coefficient of ≥0.4, and these were greater than item-other hypothesised subscale correlations, demonstrating good convergent and divergent validities respectively. Hindi-CPQ11-14 was associated with self-ratings of the oral health and overall P-CPQ scores demonstrating good concurrent validity. Hindi-CPQ11-14 showed a factor structure different from the English CPQ11-14 and exhibited good validity and reliability.
