[HIRANUMA-7] Validation of a Mongolian version of the Geriatric Oral Health Assessment Index (GOHAI-MGL) in elderly
[Abstract]
[Objective]
The GOHAI is a constantly used instrument to measure oral health-related quality of life (OHRQoL) in the elderly, however, it has still never been applied in Mongolia. This study aimed to translate the original English version of the GOHAI into a Mongolian version (GOHAI-MGL) and to test the validity and reliability of the GOHAI-MGL in an elderly population.
[Methods]
The GOHAI questionnaire was translated into Mongolian, discussed by an expert panel, back-translated to the original, pilot-tested, and assessed for cognitive and conceptual equivalence. GOHAI was translated into the Mongolian language and self-administered to 201 subjects aged 60 years or above. The measures for reliability, and concurrent, convergent, and discriminant validity were assessed.
[Results and Discussion]
Internal consistency was confirmed by Cronbach’s alphas of 0.83. Item-total score correlations were between 0.3 and 0.7 for item all in the group. The average inter-item correlations were 0.3317. Low GOHAI scores were associated with perceptions of poor oral and general health, low satisfaction with oral health, and a perceived need for dental treatment. The Mongolian 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.
