Translation of English Version of Oral Health Impact Profile‑14 into Gujarati

Abstract

Introduction: Any quality of life (QoL) assessment tool needs to be validated in the language of the participants to whom it is administered. Several language versions of oral health impact profile‑14 (OHIP‑14) already exist, for example, in German, Swedish, Hebrew, Chinese, Hindi, and Scottish. The present study has tried to establish a Gujarati version of OHIP‑14. This Gujarati version of OHIP‑14 would be useful to assess the impact of oral health on QoL of dental patients, who understand Gujarati. Aim: This study aimed to translate and validate the Gujarati version of OHIP‑14. Materials and Methods: The original English version of the OHIP‑14 was translated using the World Health Organization method (forward‑backward translation technique), and then 109 participants were given English as well as Gujarati versions of OHIP‑14 questionnaire. Filled questionnaires were collected from the participants and subjected to statistical analysis. Results: All the 14 questions showed no statistically significant difference between the English version of OHIP‑14 and the translated Gujarati version of OHIP-14. Results of unpaired t-test (P = 0.103) were not statistically significant. Pearson’s correlation coefficient test was 0.990, suggesting that the translated Gujarati version is highly correlated with the original English version. Conclusions: The translated Gujarati version of OHIP‑14 is a precise, valid, and reliable instrument for assessing oral health‑related QoL among Gujarati population.
