[EO-6] 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 elderly1, 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. The questionnaire sought information about sociodemographic details, tooth brushing, denture care, missing teeth, decayed teeth, gingival bleeding, dental visits, habits related to cigarettes, the Eichner index, and self-reported perceptions of general and oral health.
[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. Item-dimension and dimension-total correlations were between 0.3 and 0.7 and around 0.6 respectively for the dimensions “physical functioning”, “pain and discomfort” and “psychosocial functioning”. 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. Eichner Index showed a significant relation between perceived chewing ability, and GOHAI questionnaire (p < 0.05). 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.
