Abstract [en]

In this chapter, assessment of subjective driving skills is discussed from a measurement perspective, and illustrated by the development and validation of an instrument for subjective driving skills in Sweden. Usually, people's subjective driving skills have been examined in relation to the average driver. However, by using such a design, it is difficult to examine if novice drivers are overconfident or not with respect to their own skills. Instead, there is a need to compare subjective and observed driving skill. The Self-Efficacy Scale for Driver Competence (SSDC) was developed in order to assess perceived driver competence with respect to aspects of driving skill. The idea was to compare SSDC responses with driving test performance to examine the accuracy of perceived competence. The construct validity of the SSDC was examined in several studies, and although these studies indicated that the instrument was a valid measure of subjective driving skills, the SSDC was further improved by additional revisions. In conclusion, due to the importance of validating instruments before using them and due to the fact that this process requires both time and effort, there are potential benefits of developing and validating an instrument that can be used in several countries.
