Introduction: Oral health has an impact on overall general health. It is important to assess the influence of these oral disorders on quality of life. Aim: To validate a Hindi version of the oral health impact profile-14 (OHIP-14) and to assess the instrument's psychometric properties in the Indian population. Materials and Methods: A cross-sectional study was performed in Moradabad city with a sample of 186 participants. The same individuals underwent clinical examinations by a calibrated dentist for recording simplified oral hygiene index (OHI-S) index. The OHIP was initially translated and cross-culturally adapted to Hindi following guidelines; then, subsequently validated for the psychometric characteristics of reliability and validity. The reliability of the OHIP-14 was assessed by the use of Cronbach's coefficient. Reproducibility was evaluated by measuring test-retest reliability (intraclass correlation coefficient). Results: The overall value of Cronbach's alpha (α) coefficient of the OHIP-14 was estimated to be 0.8. The corrected item-total correlation coefficients values were above 0.2 that has been recommended for including an item in a scale. All Spearman's rank correlation coefficients were statistically significant, whereas the highest association was detected within the physical disability subscale (rs = 0.37), and the lowest within the social disability (rs = 0.08). It was seen that the OHIP-14 scores were higher for those individuals who had higher OHI-S scores and vice-versa. Conclusion: The translated Hindi version of OHIP-14 questionnaire is a reliable and valid instrument to measure the oral health-related quality of life in the Indian adult population.
