[A comprehensive evaluation on psychological quality among automobile drivers].
OBJECTIVE
To study the comprehensive evaluation on the indexes of psychological quality on automobile drivers.


METHODS
A index system, consisted of seven psychological indexes (including relevant physiological indexes), was developed through Delphi method and mathematical statistics. Basic data of the seven psychological and physiological indexes including mean, standard deviation and percentile, were taken from more than 8,000 occupational licensed automobile drivers and more than 6,000 trainees who were randomly sampled from 5 cities across China. The weight coefficients of indexes were determined by analytical hierarchy process (AHP).


RESULTS
Comprehensive evaluation equations of the occupational automobile drivers and the trainees were established respectively. The critical values of evaluation were divided into grades by the percentiles of evaluated values. Verified results showed that there was significant difference of the values under evaluation between drivers who had accidents and who did not (t = 14.68, P < 0.01; H = 73.61, P < 0.001). The test of consistence showed that the consistence was quite good (rate of consistence = 92.99%; kappa = 0.85).


CONCLUSIONS
Results showed that the comprehensive equations for evaluation were reasonable and feasible for detecting the potential accident-proneness drivers.
