It takes two: a brief report examining mutual support between parents and teens learning to drive

Factors Influencing Participation and Engagement in a Teen Safe Driving Intervention: A Qualitative Study

(1) Background: Few teen driving safety programs focus on increasing parental engagement with high-risk teen drivers, specifically those with a traffic violation. This study explored parents'/guardians' ('parents') experiences with a teen driving safety program, ProjectDRIVE, including facilitators and barriers to program engagement. (2) Methods: We conducted virtual, semi-structured interviews with parents who completed ProjectDRIVE, which included in-vehicle driving feedback technology and individualized virtual training with parents on effective parent-teen communication. (3) Results: Twenty interviews (with 17 females and three males) were transcribed verbatim and independently coded by three coders using systematic, open, and focused coding. Three major themes were identified: factors influencing a parent's initial decision to participate, factors influencing continued engagement, and perceived benefits of participation. The decision to participate was influenced by these subthemes: parental motivation to help their teen, perceived program usefulness, program endorsement, program incentives, parents' busy schedules, and lack of access to a car/internet. Subthemes impacting continued engagement included enhanced communication skills, teen willingness to engage, strong parental engagement, and teens' other priorities. Perceived benefits included greater self-efficacy in communication, improved communication patterns and frequency, and enhanced parent-teen relationships. (4) Conclusions: These findings may set the foundation for developing and implementing future court-ordered parent-based teen safe driving programs for teens with traffic citations.

Promoting transportation safety in adolescence: the drivingly randomized controlled trial

BACKGROUND

The impact of young drivers' motor vehicle crashes (MVC) is substantial, with young drivers constituting only 14% of the US population, but contributing to 30% of all fatal and nonfatal injuries due to MVCs and 35% ($25 billion) of the all medical and lost productivity costs. The current best-practice policy approach, Graduated Driver Licensing (GDL) programs, are effective primarily by delaying licensure and restricting crash opportunity. There is a critical need for interventions that target families to complement GDL. Consequently, we will determine if a comprehensive parent-teen intervention, the Drivingly Program, reduces teens' risk for a police-reported MVC in the first 12 months of licensure. Drivingly is based on strong preliminary data and targets multiple risk and protective factors by delivering intervention content to teens, and their parents, at the learner and early independent licensing phases.

METHODS

Eligible participants are aged 16-17.33 years of age, have a learner's permit in Pennsylvania, have practiced no more than 10 h, and have at least one parent/caregiver supervising. Participants are recruited from the general community and through the Children's Hospital of Philadelphia's Recruitment Enhancement Core. Teen-parent dyads are randomized 1:1 to Drivingly or usual practice control group. Drivingly participants receive access to an online curriculum which has 16 lessons for parents and 13 for teens and an online logbook; website usage is tracked. Parents receive two, brief, psychoeducational sessions with a trained health coach and teens receive an on-road driving intervention and feedback session after 4.5 months in the study and access to DriverZed, the AAA Foundation's online hazard training program. Teens complete surveys at baseline, 3 months post-baseline, at licensure, 3months post-licensure, 6 months post-licensure, and 12 months post-licensure. Parents complete surveys at baseline, 3 months post-baseline, and at teen licensure. The primary end-point is police-reported MVCs within the first 12 months of licensure; crash data are provided by the Pennsylvania Department of Transportation.

DISCUSSION

Most evaluations of teen driver safety programs have significant methodological limitations including lack of random assignment, insufficient statistical power, and reliance on self-reported MVCs instead of police reports. Results will identify pragmatic and sustainable solutions for MVC prevention in adolescence.

Introducing accompanied driving in Denmark. Safety-related differences between youth licensing with immediate or delayed access to solo driving

In Denmark, the legal license age was lowered from 18 to 17, to allow practice with an experienced driver before solo driving from age 18. The change gives the candidate driver a choice between: a) licensing at age 17 followed by a phase of accompanied driving until solo driving at age 18 (L17), and b) licensing at age 18 (or older) giving immediate access to solo driving (L18). The purpose of this study is: First, to explore safety-related differences between youth choosing the L17 or the L18 option, with a particular focus on safety attitude and self-assessed driving skills. Second, to map patterns in the use of accompanied driving and its predictors as well as the interaction between the L17 driver and the accompanying person (ACP). A sample of 632 drivers (53% male) between 17 and 19 years of age completed a survey. Among the participants 61% licensed through L17 and 39% through L18. Our results identify different risk profiles between L17 and L18. A higher score on perceptual-motor skills, lower score on safety skills and lower support to speed limits predicted L17. Female L17 were more safety-oriented compared to male L17. L17 who had experienced a supportive atmosphere and engagement in complex traffic situations during the drive were more likely to indicate that accompanied driving had improved their driving skills. However, results also indicate that the amount of experience obtained by L17 may be insufficient to obtain a safety benefit. Measures to address speeding and other risk-taking behaviours among male candidate drivers are needed to ensure a safety benefit of the Danish accompanied driving scheme. In addition, requirements may be needed to increase the amount of accompanied driving. Finally, parent guidelines could support the creation of a positive atmosphere during the drive.

Self-regulation differences across learner and probationary drivers: The impact on risky driving behaviours

Risky driving behaviours are a known contributor to young drivers' overrepresentation in road trauma, with self-regulation suggested as an important associated construct, but yet to be extensively explored. The aims of this study were to examine the utility of self-determination theory in explaining risky driving behaviours and to explore differences between young Learner and Provisional (P1)- licensed drivers in regard to their self-regulated safety orientation and engagement in risky driving behaviours. Learners (n = 1038) and P1(n = 589) drivers, aged 16-19 years, responded to a 91-item online survey, including self-regulated safety orientation items adapted from self-determination theory and inattentive and intentional risky driving behaviour items. Results showed that self-determination theory had good predictive power for the two types of risky driving behaviours for both licence groups. Learner and P1 drivers' engagement in risky behaviours was similar, however, the relative importance of self-regulated safety orientation elements to reduced engagement in these behaviours differed. Learners' engagement in intentional risky behaviours reflected greater perceived effort/importance and pressure/tension compared to P1 drivers. Greater effort/importance is an overarching indicator of internalised regulation concerning safe driving behaviours, which might be primed when first exposed to driving. However, greater perceived pressure/tension suggests that internalisation of self-regulatory processes is being suppressed during the Learner phase. This might stem from the required presence of driver trainers and supervisory drivers, as well as interactions with other road users. Whilst only tentative explanations in this first exploration, the findings suggest there is potential for greater efforts in Learner driver training and supervision to encompass the types of skills and learning that encourage the development of self-regulation to reduce risky driving behaviours during both the Learner and P1 stage. These findings contribute to the limited research regarding self-regulation by young novice drivers and informs a better understanding of the psychological influences of engagement in risky driving behaviours, including the first such examination among early independent licensed drivers.

Psychological Constructs Related to Seat Belt Use: A Nationally Representative Survey Study

Seat belt use can significantly reduce fatalities in motor vehicle crashes (Kahane, 2000). Nevertheless, the current U.S. seat belt use rate of 89.6% (Enriquez & Pickrell, 2019) indicates that a relatively small but pervasive portion of the population does not wear seat belts on a full-time basis. Whereas much is known about the demographic predictors of seat belt use, far less is understood about psychological factors that predict individual proclivities toward using or not using a seat belt. In this study, we examined some of these potential psychological predictors. A probability-based web survey was conducted with 6,038 U.S. residents aged 16 or older who reported having driven or ridden in a car in the past year. We measured self-reported seat belt use and 18 psychological constructs and found that delay of gratification, life satisfaction, risk aversion, risk perception, and resistance to peer influence were positively associated with belt use. Impulsivity and social resistance orientation were negatively associated with belt use. Prior research has shown that psychological factors like delay of gratification, risk aversion/perception, and impulsivity predict other health behaviors (e.g., cigarette smoking, sunscreen use); our results extend this literature to seat belts and can aid the development of traffic safety programs targeted at non-users who-due to such factors-may be resistant to more traditional countermeasures such as legislation and enforcement.

The Impact of Children's Temperament on How Parents Resolve Safety Disagreements During Preadolescence

OBJECTIVES

Parents play an important role in keeping their children safe. However, this becomes more difficult during preadolescence as children seek greater autonomy away from the direct supervision of adults. The current study focused on preadolescent youth (10-13 years) and examined parent-child disagreements about safety, with a focus on determining if child temperament attributes moderate the relation between how parents learn of these and resolve these disagreements.

METHODS

A short-term longitudinal design was used. Parents and children retrospectively recalled safety disagreements together and then independently completed questionnaires about these. Parents then tracked disagreements over 1 month.

RESULTS

The behavioral attributes of inhibitory control and risk-taking propensity both moderated the relationships between parental source of knowledge of safety disagreements and subsequent methods of resolution.

CONCLUSION

Safety-promotion messaging for parents of preadolescents may need to be tailored based on child attributes to maximize effectiveness.

Parent and Teen Factors Associated with the Amount and Variety of Supervised Practice Driving

Despite the fact that a minimum number of practice hours for novice drivers has been widely adopted in the U.S., Australia, NZ and in some European countries, surprisingly little is known about the amount or variety of driving during the learner stage. One factor may be due to the difficulty in obtaining objective measures of the amount and conditions during which practice driving takes place. The purpose of this study was to use objective measures of the amount and variety of practice driving occurring during the learner permit stage, and examine how these differ according to individual and household level characteristics, which were measured at baseline using parent and teen surveys. We found that increased practice was associated with parenting practices, such as parent trust, as well as household income and pre-permit driving experience. Taken collectively, the findings suggest the amount of practice driving may be a function of the motivation or interest of the teen to drive, combined with the quality of the relationship between parents and teens and the household environment within which these characteristics are occurring. Surprisingly, in this study, teens from households with lower incomes gained more practice hours and days. Population level studies examining the association between the family context and how teenagers learn to drive are needed to confirm the findings from this study in a representative sample. The use of both naturalistic and survey methods used in this study demonstrates how they can build on one another.

Characterizing the Learning-to-Drive Period for Teens with Attention Deficits

OBJECTIVE

Motor vehicle collisions are the leading cause of death among teenagers, accounting for approximately 1 in 3 deaths for this age group. A number of factors increase crash risk for teen drivers, including vulnerability to distraction, poor judgment, propensity to engage in risky driving behaviors, and inexperience. These factors may be of particular concern and exacerbated among teens learning to drive with attention deficits. To our knowledge, our study is among the first to systematically investigate the experiences of novice adolescent drivers with attention deficits during the learner period of a Graduated Drivers Licensing program.

METHOD

Survey and on-road driving assessment (ODA) data were used to examine parent and teen confidence in the teens' driving ability, driving practice frequency, diversity of driving practice environments, and driving errors among teens with attention deficits as defined by attention-deficit/hyperactivity disorder (ADHD) diagnosis or parent-reported trouble staying focused (TSF).

RESULTS

When teens' driving skill was evaluated at the conclusion of the learner period, teens with ADHD exhibited more driving errors than their typically developing (TD) counterparts (p = 0.034). Teens with TSF were more likely to have their ODA terminated (p = 0.019), had marginally lower overall driving scores (p = 0.098), and exhibited more critical driving errors (p = 0.01) compared with TD teens.

CONCLUSION

These findings may have implications on the learning-to-drive period for adolescents with attention deficits. Adjustments may need to be made to the learner period for teens with attention deficits to account for attention impairments and to better instill safe driving behavior.

Talking with teens about traffic safety: Initial feasibility, acceptability, and efficacy of a parent-targeted intervention for primary care settings

INTRODUCTION

The aims of the current pilot study were to evaluate the feasibility, acceptability, and preliminary efficacy of the Talking with Teens about Traffic Safety Program. The program consists of a clinic-based health coaching session with parents of adolescents at their annual well-child visit to promote parent-teen communication about teen driver safety including: a Parent Handbook that is designed to serve as a primer on teen driver safety and facilitate parent-teen communication on a variety of teen driver topics; an interactive practice driving toolset; and an endorsement of the materials by the primary care provider.

METHOD

Fifty-four parent-teen dyads (n = 108 total) were recruited from a primary care practice. Dyads were randomized (1:1) into a treatment group or a usual care group. Implementation fidelity was assessed using checklists completed by health coaches and parent interviews. After 6 months, parents reported how often they talked with their teen about 12 safe driving topics (e.g., state graduated driver licensing laws).

RESULTS

Parents in the treatment group reported more frequent discussions than parents in the control group on 7 out of the 12 topics. Fidelity data indicate that 100% of sessions were implemented as designed and were acceptable to parents.

CONCLUSIONS

The program was feasible to administer and there was evidence for preliminary efficacy. Generally, effects were larger for more infrequently discussed topics, which is to be expected due to the potential for ceiling effects on more commonly discussed topics (e.g., distracted driving). A larger multi-site study is warranted.

PRACTICAL APPLICATIONS

The results from this pilot study provide support for implementation fidelity and establish a proof-of-concept for the Talking with Teens about Traffic Safety Program. The results provide guidance for developing partnerships with pediatricians and parents to develop parent-teen communication interventions on injury prevention topics.

Can Adolescent Drivers' Motor Vehicle Crash Risk Be Reduced by Pre-Licensure Intervention?

PURPOSE

Although motor vehicle crashes are the leading cause of death for adolescents, there is a scarcity of research addressing adolescents' lack of pre-licensure practical driving experience, which is theorized to increase their post-licensure crash risk.

METHODS

Utilizing police-reported crashes and survey data from a randomized and quasi-randomized trial (n = 458 adolescents, 16 or 17 years of age at enrollment), the impact of a parent-directed supervised practice driving intervention and a comprehensive on-road driving assessment (ODA) with feedback was evaluated on adolescent drivers' motor vehicle crashes involvement.

RESULTS

Compared with the control condition, a nonsignificant 20% relative reduction in risk was observed for the parent-directed intervention: adjusted hazard ratio  = .80 (95% confidence interval [CI] .44, 1.43); the unadjusted absolute risk reduction was 1.1% (95% CI -4.4, 7.1). Exposure to the ODA resulted in an 53% relative reduction of risk: adjusted hazard ratio  = .47 (95% CI .24, .91); the unadjusted absolute risk reduction was 5.4% (95% CI -.3, 10.7).

CONCLUSIONS

Comprehensive ODA might be protective for adolescents; however, additional research is needed.

Graduated driver licensing (GDL) in the United States in 2016: A literature review and commentary

This is the sixth in a series of reviews of research on graduated driver licensing (GDL) published in the Journal of Safety Research, the present review covering the period mid-2012 through 2016. In the two decades since GDL programs began to be introduced on a widespread basis in the United States, a vast amount of research has been published. The current review discusses recent research and the present state of knowledge on the following topics: characteristics of the novice driver population; effects of GDL on crashes for ages 16-19; the learner and intermediate periods; night and passenger restrictions; cellphone laws; GDL for older novices; enforcement of GDL rules; and programs attempting to influence GDL compliance and safe driving practices in general. GDL stands out as a successful policy for reducing teen driver crashes and is worth building on to extend its benefits. Strengthening existing GDL programs has the most potential for producing further crash reductions.

Factors Influencing Learner Permit Duration

An increasing number of countries are requiring an extended learner permit prior to independent driving. The question of when drivers begin the learner permit period, and how long they hold the permit before advancing to independent licensure has received little research attention. Licensure timing is likely to be related to "push" and "pull" factors which may encourage or inhibit the process. To examine this question, we recruited a sample of 90 novice drivers (49 females and 41 males, average age of 15.6 years) soon after they obtained a learner permit and instrumented their vehicles to collect a range of driving data. Participants completed a series of surveys at recruitment related to factors that may influence licensure timing. Two distinct findings emerged from the time-to-event analysis that tested these push and pull factors in relation to licensure timing. The first can be conceptualized as teens' motivation to drive (push), reflected in a younger age when obtaining a learner permit and extensive pre-permit driving experience. The second finding was teens' perceptions of their parents' knowledge of their activities (pull); a proxy for a parents' attentiveness to their teens' lives. Teens who reported higher levels of their parents' knowledge of their activities took longer to advance to independent driving. These findings suggest time-to-licensure may be related to teens' internal motivation to drive, and the ability of parents to facilitate or impede early licensure.

Naturalistic assessment of the learner license period

The purpose of this study was to describe the characteristics and progression of practice driving during the learner license period in a sample of teenagers. During the first and last 10h of practice driving, we examined (1) the amount, variety and complexity of conditions of practice; (2) the nature of parental instruction; and (3) errors that teens made while driving. Data were collected from 90 teens and 131 parents living in Virginia, USA, using in-vehicle cameras, audio recorders, GPS and trip recorders. Based on data collected from the instrumented vehicles, teens practiced for 46.6h on average, slightly higher than the GDL requirement for their jurisdiction, though half did not complete the required 45h of practice and only 17% completed the required 15h of night time driving. Exposure to diverse roadways increased over the practice driving period, which averaged 10.6 months. Most driving instruction occurred in reaction to specific driving situations, such as navigating and identifying hazards, and could be characterized as co-driving. Higher order instruction, which relates to the tactics or strategies for safe driving, was less frequent, but remained stable through the practice driving period. Instruction of all forms was more likely following an elevated gravitational force (g-force) event. Errors decreased over time, suggesting improvements in manual and judgment skills, but engagement in potentially distracting secondary tasks increased (when an adult was in the vehicle). A small percentage of trips occurred with no passenger in the front seat, and the g-force rate during these trips was almost 5 times higher than trips with an adult front-seat passenger. Taken collectively, these findings indicate (1) most teens got at least the required amount of supervised practice, but some did not; (2) instruction was mainly reactive and included some higher order instruction; (3) teens driving skills improved despite increased exposure to complex driving conditions, but secondary tasks also increased. Opportunities remained for improving the quality and variability in supervision and enhancing the development of skills during the lengthy period of practice.

Longitudinal study of driver licensing rates among adolescents and young adults with autism spectrum disorder

Driving may increase mobility and independence for adolescents with autism without intellectual disability (autism spectrum disorder); however, little is known about rates of licensure. To compare the proportion of adolescents with and without autism spectrum disorder who acquire a learner's permit and driver's license, as well as the rate at which they progress through the licensing system, we conducted a retrospective cohort study of 52,172 New Jersey residents born in the years 1987-1995 who were patients of the Children's Hospital of Philadelphia healthcare network ⩾12 years of age; 609 (1.2%) had an autism spectrum disorder diagnosis. Electronic health records were linked to New Jersey's driver licensing database (2004-2012). Kaplan-Meier curves and log-binomial regression models were used to determine the age at and rate of licensure, and estimate adjusted risk ratios. One in three adolescents with autism spectrum disorder acquired a driver's license versus 83.5% for other adolescents and at a median of 9.2 months later. The vast majority (89.7%) of those with autism spectrum disorder who acquired a permit and were fully eligible to get licensed acquired a license within 2 years. Results indicated that a substantial proportion of adolescents with autism spectrum disorder do get licensed and that license-related decisions are primarily made prior to acquisition of a permit instead of during the learning-to-drive process.

Effectiveness of Parent-Focused Interventions to Increase Teen Driver Safety: A Critical Review

PURPOSE

We critically reviewed recent parent-directed teen driving interventions to summarize their success in meeting stated goals; identify promising intervention components and knowledge gaps; aid in the selection, adaptation, and dissemination of effective interventions; and guide future research efforts.

METHODS

We focused on interventions that included a direct parent component, explicitly stated outcomes related to the teen and/or their parents, were evaluated for parent or teen outcomes, targeted drivers younger than the age of 21 years, and had at least one evaluation study published since 1990 and in English. We conducted a comprehensive systematic search of 26 online databases between November 2013 and January 2014 and identified 34 articles representing 18 interventions.

RESULTS

Several interventions-in particular, those that had an active engagement component, incorporated an in-vehicle data recorder system, and had a strong conceptual approach-show promise in improving parental supervisory behaviors during the learner and early independent phases, increasing teen driver skill acquisition, and reducing teens' risky driving behaviors.

CONCLUSIONS

We identify essential characteristics of effective parent-involved teen driving interventions and their evaluation studies, propose a comprehensive and multitiered approach to intervention, and discuss several research areas and overarching issues for consideration.

TeenDrivingPlan effectiveness: the effect of quantity and diversity of supervised practice on teens' driving performance

PURPOSE

The large contribution of inexperience to the high crash rate of newly licensed teens suggests that they enter licensure with insufficient skills. In a prior analysis, we found moderate support for a direct effect of a web-based intervention, the TeenDrivingPlan (TDP), on teens' driving performance. The purpose of the present study was to identify the mechanisms by which TDP may be effective and to extend our understanding of how teens learn to drive.

METHODS

A randomized controlled trial conducted with teen permit holders and parent supervisors (N = 151 dyads) was used to determine if the effect of TDP on driver performance operated through five hypothesized mediators: (1) parent-perceived social support; (2) teen-perceived social support; (3) parent engagement; (4) practice quantity; and (5) practice diversity. Certified driving evaluators, blinded to teens' treatment allocation, assessed teens' driving performance 24 weeks after enrollment. Mediator variables were assessed on self-report surveys administered periodically over the study period.

RESULTS

Exposure to TDP increased teen-perceived social support, parent engagement, and practice diversity. Both greater practice quantity and diversity were associated with better driving performance, but only practice diversity mediated the relationship between TDP and driver performance.

CONCLUSIONS

Practice diversity is feasible to change and increases teens' likelihood of completing a rigorous on-road driving assessment just before licensure. Future research should continue to identify mechanisms that diversify practice driving, explore complementary ways to help families optimize the time they spend on practice driving, and evaluate the long-term effectiveness of TDP.
