Adaptation and Validation of Reflux Symptom Index into Hindi Language (RSI-H®)

Published:November 23, 2021DOI:https://doi.org/10.1016/j.jvoice.2021.10.007

      Summary

      Objective

      The current study aimed to translate, culturally adapt, and validate the Reflux Symptomatic Index in the Hindi language. Secondly, we aimed to compare its outcomes between normal individuals and people suffering from laryngopharyngeal reflux.

      Study Design

      Cross-sectional study design.

      Material and Methods

      The original Reflux Symptom Index was translated into Hindi language using the forward-backward translation method. A total of 192 participants were included in the study. Among 192 participants, 57 were healthy controls, and 135 were individuals with laryngopharyngeal reflux. Internal consistency, test-retest reliability, and clinical validity were measured.

      Results

      The majority of the population reported the presence of globus sensation. Results revealed that the Hindi version of the Reflux Symptom Index exhibited an excellent internal consistency (ie, 0.829). A significant difference was found between the mean scores of both groups, and the excellent test-retest reliability score (ie, 0.94 & 0.96) was obtained.

      Conclusion

      We can conclude that the Hindi version of the Reflux Symptom Index exhibited a similar psychometric functional property as the Original version of the Reflux Symptom Index. So, the developed tool is a quick, reliable, and valid tool to assess laryngopharyngeal reflux.
