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.
