Identifying High Risk Adolescent Drivers: Agreement between Self-Report and in-Vehicle Kinematic Event Recorders

Accurate measures of novice driving risk are needed to identify teens for targeted interventions and are also needed to evaluate teen driving safety interventions. Comprehensive, objective measures of teen driving risk are problematic to develop. The authors used data from an intervention trial to measure the agreement and trends between self-reported teen driving risk and rates of kinematic errors measured through an in-vehicle feedback device. 166 teen-parent dyads were enrolled in the study. Self-reported risky driving was assessed through the Risky Driving Inventory, which measured the frequency of risky driving actions and behaviors. Kinematic events were measured using the DriveCam by Lytx in-vehicle video feedback system. The rate of risky driving events were both calculated as rates based on vehicle miles travelled. The two measures had a low level of agreement as measured by both the proportion agreement (0.27, 95% CI [0.20, 0.35]) and squared weights kappa (0.08, 95% CI [-0.07, 0.24]). The two measures also differed in identifying high risk teen drivers. For example, among the 49 participants who had a high rate of self-reported risky behaviors, 8 (16%) had zero triggered events and 11 (22%) were in the low event rate category. These two measures have different underlying conceptual approaches, and they are unlikely to yield similar results when used to test interventions or identify high risk drivers.
