Abstract

OBJECTIVE
This study was conducted to develop the computerized attention tests for Korean adults. It also aimed at evaluating the reliability and validity of these tests and providing their normative data.
METHODS
Computerized versions of auditory & visual continuous performance tests (CPTs), controlled CPTs, and trail making test A & B were developed through several steps of preliminary applications and corrections. The test-retest reliabilities of each test was evaluated by the paired t-test and Pearson's correlation coefficient using the data from 27 normal persons. The validity of each test was evaluated by the Pearsons's correlation coefficient between the computerized test scores and the preexisting cognitive function tests using the data from 48 normal persons. The normative data were obtained from the 154 Korean adults, aged 20 to 50, whose educational levels were higher than high school graduate.
RESULTS
There were no statistical differences between the means of the test and retest scores. High correlations were also observed between the tests and retest scores. The number of correct responses of the computerized CPTs were highly correlated with each other. They were also highly correlated with the scores of the pre-existing attentional measures. Trail making test scores were highly correlated with higher cortical functions such as IQ and hypothesis formation abilities. The CPTs scores were not affected by sex, educational level, and age. The performances for the visual CPTs were higher than those of auditory tests. Trial making test scores were influenced by educational level and age. The normative data and guidelines for interpretation were provided.
CONCLUSION
Clinically applicable computerzied attention assessement tools with high reliability and validity were developed. The normative data for the Korean adults aged 20 to 50 were obtained and the guidelines for the interpretation were provided.
