Development of the Attention Dysfunction While Driving and Walking Scales, and Its Reliability and Validity

Abstract

Car drivers and pedestrians collect information proactively by activating their attentional functions in road traffic. Road traffic accidents and traffic violations were mainly caused by attentional dysfunctions. Especially, adult ADHD and healthy elderly might induce attention dysfunction. Their characteristics of attention dysfunction while driving and walking, are not completely clarified yet. In this study, a scale of attentional function by the normal adult persons (N=208) aged from 30th to 50th was to be developed as a convenient tool for solving the characteristics of attentional dysfunction. As the result, (1) this scale have four factors of “Attentional dysregulation”, “Shifting attentional functions”, “Decline in arousal levels”, and “attention destruction”, (2) getting confidential Cronbach’s alpha coefficient from each scale, (3) getting the reliable coexisted validity with total point of the items of ADHD in DSM-5 by showing the theoretical correlation. It is concluded that above results confirmed the reliability and validity of this scale.
