ABSTRACT

The purpose of this study is to secure the stability of the Korea hand function work sample test by conducting verification of reliability & validity. In order to verify reliability⋅validity of developed Korea hand function work sample test, the test based on 206 people with disabilities was conducted. The each existing Purdue Pegboard and developed Korea hand function work sample test were conducted randomly, and the test-retest method was conducted by same examiner repeatedly in order to measure reliability of Korea hand function work sample test. The criterion validity were verified, and sensitivity․specificity were shown by written ROC curves. The criterion validity was verified by comparison with Purdue Pegboard which is used as existing useful tool. First, all correlations of Korea hand function work sample test in the test-retest reliability are significant from 0.01 level and it shows very high correlations of more than 0.95 between the tests. Second, the Korea hand function work sample test shows high correlation between the existing Purdue Pegboard and test. Third, the predictive power of the AUC value was appeared high with 0.886, 0.868 in the results of the Korea hand function work sample test by using ROC curves. Fourth, Korea hand function work sample test was developed as useful tools with high convenience degree & failure prediction comparing to Purdue Pegboard. The Korea hand function work sample test is significant for the first developed work sample test tool in Korea which secured reliability and validity and it is expected to help for practical service provision of vocational evaluator for the disabled.
