Reliability and validity of the geriatric oral health assessment index in Turkey

The purpose of this study was to test the reliability and validity of the Turkish version of the Geriatric Oral Health Assessment Index (GOHAI). Data were obtained from a cross-sectional survey of 101 older adults living at a residential home in the Izmir municipality of Turkey. The Turkish version of the GOHAI showed acceptable reliability and validity. The Cronbach's alpha coefficient was 0.75, and item-scale (Pearson's) correlations varied between 0.30 and 0.67. Low GOHAI scores were associated with perceived poor oral health (p < 0.01) and dissatisfaction with oral health status (p < 0.05). Factor analyses of the index indicated a two-factor solution. It was concluded that the Turkish version of the GOHAI is a reliable and valid measure for use with Turkish adults age 65 and older.
