Assessment of validity and reliability of Hindi version of geriatric oral health assessment index (GOHAI) in Indian population.

Objective: The objective of this study was to translate the Geriatric Oral Health Assessment Index (GOHAI) into the Hindi language and assess its validity and reliability for use among people in India.

Materials And Methods: GOHAI was translated into the Hindi language and self-administered to 420 subjects aged 55 years or above. The measures for reliability, and concurrent, convergent, and discriminant validity were assessed. The questionnaire sought information about sociodemographic details, habits related to tobacco, dental visits, tooth brushing, and self-reported perceptions of general and oral health.

Results: Cronbach's alpha (0.774) showed high internal consistency and homogeneity between items. Low GOHAI scores were associated with the perceptions of poor oral and general health, low satisfaction with oral health, and a perceived need for dental care. Respondents with high socioeconomic status were likely to have high GOHAI scores.

Conclusion: The Hindi version of the GOHAI demonstrated acceptable validity and reliability, and will be an important instrument to measure oral health-related quality of life (OHRQoL) for people in this region.
