Introduction
Motor vehicle crashes (MVCs) are the leading cause of mortality among teenagers. Teen driving research has a longstanding history; however, much of this work is cross-sectional. The Eunice Kennedy Shriver National Institute for Child Health and Human Development funded a study, REACT (Roadway Experiences and Attentional Change in Teens) which combined factorial and longitudinal designs to investigate the independent and joint effects of age and driving experience on driving attention over time among young drivers.
Method
Longitudinal methods offer important contributions to teen driving research by enabling characterization of driving trajectories. This paper describes methodological considerations for longitudinal studies of teen drivers. Such considerations are organized into overarching themes, including population, recruitment, enrollment, and retention, throughout this paper. These considerations were compiled as a combination of our own experiences in REACT and previous literature. We elaborate on these considerations below to illustrate the value of each consideration.
Results
Issues encountered are discussed and strategies for dealing with various issues are described. Transportation barriers, scheduling difficulties, and skipped study milestones were among the most frequent challenges; we outline these and other issues encountered in REACT and corresponding considerations for such issues in Table 2. Sharing these experiences should aid future longitudinal investigations of young drivers, which are critically needed to reduce teen MVCs.
Conclusions
Studies similar to REACT are considerable undertakings due to the comprehensive nature of longitudinal design. Such investigations must maintain a delicate balance between appropriate amounts of rigor and flexibility in the development of thoroughly defined research questions and theoretically driven frameworks. Key considerations that have contributed to the success of REACT are outlined, challenges encountered throughout data collection are documented, and recommendations based on choices made and lessons learned to inform future longitudinal investigations on young drivers are provided.
