Objective: The purpose of this study is to standardize a Korean Drivers 65 plus by evaluating its reliability and validity.
Methods: After completing the final translation through verification, to verify the tool’s reliability and validity, 218 senior drivers, aged 65 plus, were assessed through translated versions of Drivers 65 plus, K-DBQ and MoCA-K.
Results: The translated version was completed after verification of translation and reverse translation, participant comprehensibility, and suitability; no questions were deleted or added. In reliability testing of the translated version of Drivers 65 plus, the internal reliability of the items was Cronbach’s α=0.575, and test-retest reliability was .95 by ICC. In the confirmatory factor analysis to verify construct validity, the model fit indices were as follows: NC=2.954, CFI=.806, TLI=.736, NFI=.742 and RMSEA=.095. K-Drivers 65 plus and K-DBQ had a significant positive correlation(r=.470, p<.01) while there was a significant negative correlation with MoCA-K(r=-.495, p<.01). When we tested the usefulness of the K-Drivers 65 plus to assess driving suitability in senior drivers, the AUC (.726) was confirmed to have normal accuracy in selecting suitability. K-Driver 65 plus distinguished those with a total score of 31 or more as Risk drivers and those with scores of less than 31 as Safe drivers.
Conclusion: Although K-Drivers 65 did not show high reliability and validity in this study, it was proven to be an adequate self-assessment tool for two reasons: 1) it can be easily provided to a large number of elderly drivers and 2) it is possible to prevent accidents by predicting driving suitability based on the results.
