Aim:
This study aims to validate an OHE questionnaire in Tamil to ensure linguistic and cultural accuracy for Tamil-speaking populations.
Methodology:
The study involved English-Tamil fluent adults, using a 15-item OHE questionnaire translated through expert forward and backward translations. An expert panel ensured conceptual equivalence, and a pilot study with 30 participants refined the translation. The final Tamil version was tested for internal consistency with 1500 participants and test-retest reliability with 500 persons.
Results:
The Tamil OHE questionnaire demonstrated excellent internal consistency, with Cronbach's alpha values >0.99, and high test-retest reliability, with Pearson correlation coefficients >0.90 for most items.
Conclusion:
The validated Tamil OHE questionnaire is a reliable tool for evaluating oral health-related quality of life, supporting effective, and culturally appropriate oral health interventions in Tamil-speaking regions.
