Abstract

Objectives. This study was aimed to develop a Korean version of the GOHAI for elderly people. Methods. The GOHAI for elderly people was cross-culturally adapted from English into Korean and then the derived instrument was tested for reliability and validity. The study population consisted of elderly (65+ year-old) residents of Wonju-City, South Korea. Five elderly welfare institutions were selected. Results. 615 people were invited and 155 participated in the study (response rate: 25.2%). The standardized Cronbach's alpha coefficient was 0.834. Kappa value for the test-retest was 0.482. Participants who responded that they had perceived needs for dental treatment had much lower GOHAI scores than those who did not have a perceived need for treatments (p<0.001). The results from perceived oral health conditions and perceived general health conditions exhibited similar responses; people who considered their oral or general conditions were good had significantly higher GOHAI scores (p<0.01). Conclusions. The Korean version of GOHAI was appropriate to measure the OHRQoL of older Korean people. Longitudinal studies are needed to test the sensitivity of this index.
