Passenger distractions among adolescent drivers

PROBLEM: Adolescents who drive with peers are known to have a higher risk of crashes. While passengers may distract drivers, little is known about the circumstances of these distractions among teen drivers. METHOD: This study used survey data on driving among 2,144 California high school seniors to examine distractions caused by passengers. RESULTS: Overall, 38.4% of youths who drove reported having been distracted by a passenger. Distractions were more commonly reported among girls and students attending moderate- to high-income schools. Talking or yelling was the most commonly reported type of distraction. About 7.5% of distractions reported were deliberate, such as hitting or tickling the driver or attempting to use the vehicle's controls. Driving after alcohol use and having had a crash as a driver were both significant predictors of reporting passenger-related distraction. CONCLUSION: Adolescents often experience distractions related to passengers, and in some cases these distractions are intentional. IMPACT ON INDUSTRY: These results provide information about teenage drivers who are distracted by passenger behaviors. In some cases, passengers attempted to use vehicle controls; however, it seems unlikely that this behavior is common enough to warrant redesign of controls to make them less accessible to passengers.     

Adolescent driver risk taking and driver education: evidence of a mobility bias in public policymaking

PROBLEM: Road traffic injury is the leading cause of death among adolescents in high-income countries. Researchers attribute this threat to driver risk taking, which driver education (DE) attempts to reduce. Many North American authorities grant DE graduates earlier access to unsupervised driving despite no evidence of this being a safety benefit. This theoretical article examines risk taking and DE in relation to an apparent mobility bias (MB) in policymaking. METHOD: The MB is defined, the history and sources of driver risk taking are examined, and the failure of DE to reduce collision risk is analyzed in relation to a potential MB in licensing policies. DISCUSSION: The author argues that DE's failure to reduce adolescent collision risk is associated with a MB that has produced insufficient research into DE programs and that influences public policymakers to grant earlier licensure to DE graduates. Recommendations are made regarding future research on DE and risk taking, coordinated improvements to DE and driver licensing, and a plan to reduce collision risk by encouraging parental supervision after adolescent licensure. IMPACT ON INDUSTRY: Research on adolescent driver risk taking would have direct applications in DE curricula development, driver's license evaluation criteria, graduated licensing (GDL) policies, as well as other aspects of human factor research into the crash-risk problem.     

Longitudinal examination of underage drinking and subsequent drinking and risky driving

INTRODUCTION: Alcohol use, alcohol misuse, and risky driving from adolescence into young adulthood were compared by drinking onset age. METHODS: Surveys were administered in Grades 5/6, 6/7, 7/8, 10, 12, and at approximately age 23. Participants were placed into Drinking Onset groups based on self-reported alcohol use frequency on the adolescent surveys. Driving records were examined in three age periods: under 21, 21-25, and 26+. RESULTS: The earliest drinking initiators reported higher alcohol use and misuse on each survey, and were more likely to have risky driving offenses before age 21 and to have alcohol driving offenses in all three age periods. DISCUSSION: The earliest drinking initiators engaged in risky drinking behavior and risky driving behavior that was consistently higher than those with later drinking initiation, beginning in adolescence and persisting well into young adulthood.     

Associations between driving under the influence or riding with an impaired driver and future substance use among adolescents

Objective: Risky driving behaviors among adolescents, such as riding with a drinking or impaired driver (RWID) or driving while under the influence (DUI) of alcohol or drugs, are significant public health concerns. Few studies have examined associations of RWID and DUI with future substance use and problems after controlling for baseline substance use. Given that the DUI/RWDD event may be a teachable moment to prevent future consequences (e.g., when injured or arrested), it is important to understand how this risk behavior relates to subsequent use and problems. This study therefore examined characteristics of adolescents who reported DUI and RWID and assessed their risk of future alcohol and marijuana use and consequences 6 months later.

Methods: Participants were 668 adolescents aged 12 to 18 (inclusive) recruited at 1 of 4 primary care clinics in Pittsburgh and Los Angeles as part of a larger randomized controlled trial. They completed surveys about their health behaviors at baseline and 6 months after baseline. We examined baseline characteristics of adolescents who reported DUI and RWID and then assessed whether past-year DUI and RWID at baseline were associated with alcohol and marijuana use and consequences 6 months after baseline.

Results: Fifty-eight percent of participants were female, 56% were Hispanic, 23% were Black, 14% were White, 7% were multiethnic or other, and the average age was 16 years (SD?=?1.9). At baseline, participants who reported RWID or DUI were more likely to be older, report past-year use of alcohol and marijuana, and more likely to have an alcohol use disorder or cannabis use disorder versus those who did not report RWID or DUI, respectively. At 6-month follow-up and after controlling for baseline demographics and baseline alcohol use, RWID was associated with more frequent drinking episodes in the past 3 months and greater number of drinks in the past month when they drank heavily. DUI at baseline was associated with more frequent heavy drinking episodes and alcohol and marijuana consequences 6 months later.

Conclusions: RWID and DUI are significantly associated with greater alcohol and marijuana use over time. This study highlights that teens may be at higher risk for problem substance use in the future even if they ride with someone who is impaired. Prevention and intervention efforts for adolescents need to address both driving under the influence and riding with an impaired driver to prevent downstream consequences.     

Injury surveillance trends in career–technical education: New Jersey 1999–2018

Introduction: Adolescents engaging in school-sponsored work experiences may be at risk of injury due to factors such as inexperience. This article examines trends in 20 years of reported injuries among New Jersey (NJ) adolescents engaging in school-sponsored work experiences, and compares a transition from paper to online reporting format. Methods: New Jersey requires reporting of injuries occurring during school-sponsored work experiences to the NJ Department of Education. Injuries reported by NJ schools from 1999 to 2018 (n = 2,119) were examined; incidence rates for 2008 to 2018 (n = 743) were calculated using publicly available NJ Department of Education enrollment data for the denominator, including for specific groups of students: career and technical education; special healthcare needs. Results: A downward trend in reported injuries in NJ schools was observed. However, the year online reporting became required by code (2013), an increase of nearly 50% was seen from 2012 (59–89), followed by a decline in reported incidents 2014 to 2018 (mean = 65, range 76 down to 47). Injury rate trends over time paralleled those of reported incidents. Conclusions: This study suggested worker safety and public health benefits of improvements from State of NJ code required training programs and online injury surveillance report form. Practical Applications: One potential method to address the safety and health of adolescents engaging in work experiences is the use of online reporting forms, to aid in surveillance efforts, coupled with occupational safety and health training specifically geared toward teachers and administrators who both supervise young, relatively inexperienced and vulnerable workers and who make relatively frequent worksite visits. Incorporation of specific details of the instructions on the use of a reporting form into required trainings, in addition to providing a clear, accessible guidance manual online, could further help improve youth worker safety surveillance efforts.     

Adolescent noncompliance with age-specific versus universal US motorcycle helmet laws: Systematic review and meta-analysis

Introduction: The U.S. experience with motorcycle helmets affords an important insight into the responses of adolescents to age-specific laws. Political contention has led to a number of U.S. state law changes back and forth between universal and age-specific laws. Because both kinds of law require adolescent motorcyclists to wear helmets, relatively few studies have focused on how the law type affects their behavior. Method: Differential behavior is tested by a systematic review of literature, leading to a meta-analysis, in relation to the experience of various states’ motorcycle helmet laws. An electronic search was conducted for before-and-after studies in U.S. states that include data on adolescent helmet usage – both with a universally applicable motorcycle helmet law, and with an age-restricted law (usually, under-21 or under-18) – from observational, injury or fatality records for a certain period (e.g., 12 months) pre and post the state law change. Results: The search yielded ten studies, including two that compared a set of age-specific law states with a set of universal law states over the same time period. Heterogeneity analysis of seven single-state studies with raw data revealed an acceptable fit for a random-effects model. Additional noncompliance with age-restricted laws was indicated by an attributable percentage among exposed of over 65% and odds ratio exceeding 4. Conclusions: About two-thirds of adolescent noncompliance with age-restricted motorcycle helmet usage laws disappears with universal applicability. Evidence from numerous international studies of youth reaction to helmet laws suggests that a large part of the greater compliance with universal laws is due to their conveying a more convincing message that helmets afford protection against injury. Practical Applications: The meta-analysis provides fresh, young-rider perspective on the continuing debate over motorcycle-helmet laws. Broader insight into adolescent psychology suggests considering alternatives to age-restricted laws more widely in safety and health policy.     

Exploring differences in the workplace violence experiences of young workers in middle and late adolescence in the United States

Problem: Young workers, typically characterized as 15–24 years of age, are commonly employed in jobs where the risk of workplace violence is high. It is unknown how these young workers, at varying stages of development, might understand and respond to workplace violence differently. We set out to explore whether the experiences and understandings of young workers varied between those in middle (ages 15–17) and late (ages 18–24) adolescence. Method: Separate focus groups were conducted with working students (n = 31), ages 15–17 and ages 18–24, who had either experienced or witnessed workplace violence. A focus group guide was used to facilitate the sessions which were recorded, transcribed, and content analyzed for themes. Results: Those in the older group experienced more severe episodes of sexual harassment and physical assault, reported using formal mechanisms for reporting, and noticed an employer focus on customer satisfaction over employee safety, while the younger participants tended to report to their parents. Both groups reported negative effects of experiencing workplace violence including depression, anxiety, feelings of worthlessness, and spill over into personal life. Discussion: Findings suggest that young workers at different developmental stages may experience and respond to workplace violence differently. Further research is needed to see if these results are generalizable. Summary: It is imperative that we understand the distinct differences between these subsets of young workers and how they experience and respond to workplace violence in order to improve research, policy development, and prevention/intervention mechanisms. Practical Applications: Understanding that differences exist among young workers based on age due to developmental stage, lack of experience, education, and social awareness can enable employers, companies, policy makers, and researchers the opportunity to better address the issue of workplace violence in this population.     

Effects of gender, sex-stereotype conformity, age and internalization on risk-taking among adolescent pedestrians

The objective of this study is to explore the effects of sex-stereotype conformity and the internalization of traffic rules on risk-taking among adolescent pedestrians. Sex-stereotype conformity, danger perception, internalization of traffic rules and risky behaviors self-reported by 278 adolescent pedestrians (130 boys and 148 girls) aged 12–16 were measured. The results show an effect of sex-stereotype conformity on the internalization of traffic rules and risky behavior. Furthermore, the results show an effect of internalizing traffic rules on the risky pedestrian behaviors. Thus, it appears that, more than biological sex, it is the level of masculinity and the level of internalization of the rules that explain gender differences in risk-taking among adolescent pedestrians.     

The transtheoretical model of change in adolescents: implications for injury prevention

INTRODUCTION: Many injury prevention interventions require changes in human behavior to reduce self-risk or risk to others. Promising injury prevention interventions may be discarded if they lack power to create a significant difference in outcomes when judging their ability to "move a person from nonaction or negative action to positive action (safety)." The transtheoretical model of change (TMC) allows greater sensitivity in detecting along the change process where an intervention may be effective. The stages of change consist of precontemplation, contemplation, preparation, action, maintenance, and termination. Change is not viewed as an "all or none phenomenon." METHOD: Use of the TMC was examined using a quasiexperimental, cross-over design involving high school agriculture students enrolled in 21 schools in Kentucky (n=9), Iowa (n=7), and Mississippi (n=5). A series of physical and narrative simulations (safety training exercises) were developed with a focus on preventing amputation, spinal cord injury, hypersensitivity pneumonitis, and noise-induced hearing loss. Contemplation and action, as part of the TMC, were measured using a 10-item, Likert-type, stages of change (SOC) instrument comprised of two subscales (reliability coefficients were.88 and.81, respectively). The final sample consisted of 790 students (373 treatment and 417 control). RESULTS: There was a significant group effect for both contemplation, F(1,732)=197.4; p<.0001, and action, F(1,730)=106.1; p<.0001. A convenience sample of 29 of the participating students was selected for follow-up farm visits 1 year postparticipation. Of these students, 25 (86%) had made safety behavior changes in their farm work. IMPACT ON INDUSTRY: The use of the TMC model can provide researchers with greater precision in examining intervention effectiveness in promoting change.     

Pediatrician attitudes, knowledge, and practice behavior regarding teen driving safety

Problem

Each year about 4,000 teens ages 16-19 die on U.S. roads. Injury prevention counseling is recommended as a valuable and cost-effective part of routine health supervision. This study describes pediatrician knowledge and practice regarding teen driving safety.

Methods

A 31-item self-administered survey was mailed to pediatricians.

Results

160 of 392 pediatricians (41%) completed the survey. During a health supervision visit 93% of pediatricians reported discussing seat belt use, 89% impaired driving, 54% teen licensing laws, and 16% parent teen contract. Half reported having a teen in their practice killed in a crash.

Conclusions

A majority surveyed report discussing and counseling teens on first wave teen driver safety issues (seat belts, alcohol use), but most do not discuss graduated driver licensing laws or related issues. Impact on Industry: Broadly adopted, this inexpensive counseling approach, could lead to reductions in teen motorvehicle crash injuries.
