![]() The effects of a mobile telephone task on driver behaviour in a car following situation. Paper presented at the IMAGE 2004 Conference, Scottsdale, AZ.Īlm, H., & Nilsson, L. A process for developing scenarios for driving simulations. We concluded that although the relationship between self-reported behaviors and observed responses in the simulator falls short of perfect correspondence, the data collected from the driving simulator are valid measures of the behaviors of interest.Īllen, R. ![]() Discriminant validity was assessed using a multitrait-multimethod matrix of simulator and questionnaire data. Concurrent validity was evaluated with an analysis of simulator accident involvement and attention deficit hyperactivity disorder status. Significant relationships were found across six measures: accidents, speeding, velocity, passing, weaving between traffic, and behavior at stop signs. Convergent validity was assessed by regressing behaviors observed in the driving simulator on self-reported measures of driving behaviors. Following a description of the experimental methods and setting, an argument for the face validity of the data is advanced. The issue of validity concerns the extent to which measures from the experimental context map onto constructs of interest. In this article, we use self-reported driving behaviors from a written questionnaire to assess the measurement validity of data derived from a driving simulation.
