Abstract


OBJECTIVES
This study was conducted to prove the validity of the Korean version of the Executive Interview (K-EXIT) which was developed by Donald Royall as a bed-side test to measure the executive function.
METHODS
The K-EXIT was developed and applied to 169elderly people with other executive functiontests.The internal consistency,reliability and the validity of the K-EXIT were analyzed.
RESULTS
The K-EXIT showed high internal consistency (Crohnbachalpha= 0.766) and high inter-rater reliability (r=0.997, p<0.01).The K-EXIT total score was well correlated with verbal fluency test (r=-0.460, p<0.001), and the initiation-perseveration-change score (r=-0.598, p<0.005).
CONCLUSION
The K-EXIT is a reliable and valid instrument for assessing executive function of the Korean elderly people. It may be also useful for the less well-educated people.
