Derivation and validation of oral health impact profile-14 for odia-speaking adults

Background: Assessment of oral health-related quality of life (OHRQoL) is gaining importance. However, there is unavailability of such a tool in the linguistically and culturally different settings such as that of Odisha. The aim of this study was derivation and validation of Oral Health Impact Profile-14 (OHIP-14) for Odia-speaking adults. Methods: The OHIP-14 questionnaire was translated into the Odia language conforming to the standard cross-cultural translation methodology. The tool was validated and used for estimating the quality of life in 150 dental patients (36.31 ± 11.57 years; 77 males and 73 females). The internal consistency for reliability was measured using Cronbach's alpha. Construct validity of the instrument was checked with self-reported oral health and oral hygiene index scores. Results: Cronbach's alpha for the Odia version of the OHIP-14 was 0.862. The corrected item-total correlation coefficients ranged from 0.316 (functional limitation) to 0.674 (handicap). It was observed that patients with good self-perceived oral health had significantly lower OHIP-14od scores and those with poor oral hygiene had significantly greater OHIP-14od scores. Conclusion: Despite cultural variations, the translated Odia version of the OHIP-14 questionnaire is a reliable and valid instrument to measure the OHRQoL in the Odia-speaking adult population.
