Methods
Parent-teen
SECONDARY
We propose a randomized controlled trial with 1,200 parent-teen dyads to evaluate our central hypothesis, which is that Drivingly can reduce adolescent drivers’ risk for a MVC during the first 12 months of licensure (Hypothesis 1). Our secondary focus is to evaluate Drivingly’s conceptual model (Hypothesis 2 and 3).Hypothesis 2: Drivingly will:
improve practice driving (e.g. quantity, diversity, challenge).increase the frequency of parent-teen communication about traffic safety driving topics (e.g., GDL).increase adolescent drivers’ self-regulation (i.e., self-restriction of driving in conditions that are deemed more challenging and dangerous).increase parents’ limit-setting on post-license driving (e.g., passenger restrictions).reduce adolescents’ risky driving styles (e.g., angry, high-velocity) and increase safe driving styles (e.g., patient, cautious); and.Hypothesis 3: Parent-teen (P-T) communication, practice driving, limit-setting, driving style, and self-regulation will mediate the effect of Drivingly on MVC risk.
