RELIABILITY AND VALIDITY ASSESSMENT OF A NEWLY DEVELOPED BATTERY OF DRIVING RELATED VISION TESTS

The usefulness of a Driver Vision Tester (DVT), developed by Henderson & Burg, as a licensing screening device was evaluated by administering the tests to 351 accident- involved drivers and 149 drivers not involved in accidents. The DVT was evaluated in terms of its (a) reliability, (b) praciticality, and (c) predictive validity of accident involvement. The results suggest that the DVT is a reliable method for measuring most of the visual functions included in the battery, since it yields consistent results with very little administrator and learning effects. Detailed examinations of the validity of the individual tests reveal that dynamic visual acuity, static acuity under low levels of illumination and perhaps angular extent of the effective visual field, differentiate between accident-at-fault drivers (i.e., judged to be at fault) and non-accident- involved drivers. In light of the present time needed to administer the DVT, it may be significantly shortened expecially since the static acuity tests and dynamic acuity tests seem to be partially independent based on a factor analysis. /A/
