Changes in risky driving behavior from age 21 to 26 years

Aim: The aim of this study was to determine whether the prevalence of risky driving behavior changed between ages 21 and 26 years, among a cohort of young people. Method: This study was part of the Dunedin Multidisciplinary Health and Development Study, which is a longitudinal study of a birth cohort. This study involved examining changes in the prevalence of risky driving behavior among young adults at ages 21 and 26 years. At both ages, 936 members of the cohort were administered face-to-face interviews, using a structured questionnaire that included items on a range of risky driving and thrill-seeking activities. Results: The results showed that risky driving was predominantly a male activity, but by 26 years of age, many had “matured out” of this behavior. At the same time, the desire for thrill-seeking increased among the males. Among the females, there were few significant changes between ages 21 and 26 years, but at both ages, the prevalence of risky driving and thrill-seeking was relatively low. Impact on industry: These results show that the main target population for road safety interventions aimed at reducing risky driving behavior should be young, male drivers.     

Social environment versus cycling competency predicting risk-taking in 11- to 13-year-old cyclists in The Netherlands

Abstract

Objectives: From age 12 onwards, cycling injuries begin rising in The Netherlands. A known contributing factor is younger children’s underdeveloped competency to deal with complex and hazardous traffic situations, and their exposure to such situations strongly increases after transitioning to secondary school. Little is known about intentional risk-taking as a contributing factor. In this developmental stage, children become increasingly vulnerable because of intentional risk-taking, affecting their safety and health. The incidence, predictors in the child’s social environment, and trends of such risks are systematically monitored; for instance, for alcohol use, smoking, and cyber bullying. Such monitors do not include risky road behavior. This exploratory field study examined the frequency of intentional risky cycling, its relationship with the perceived social environment, and relative to cycling competency measured as the ability to detect emerging hazards quickly.

Methods: Three hundred thirty-five students between 11 and 13 years of age (51% male) completed computerized tests of hazard perception skill and surveys on crashes, risk-taking, peer pressure, perceived risk-taking by parents or friends, and exposure to risky driving as passenger.

Results: Frequent risk-taking was associated with higher crash frequency. Stepwise regression confirmed that children who more often took risks on the road were also more sensitive to peer pressure, had more often been passengers of risky drivers, had parents and friends who exhibited risky behaviors in traffic more often, and perceived hazards as less dangerous but, in contrast to expectations, did not do worse on the detection of hazards. The predictors explained 28% of the variance in total risk-taking but varied from 6 to 20% depending on the specific risk-taking behavior concerned.

Conclusions: At least 20% of children sometimes or more often take risks in traffic. Children who feel peer pressure to behave in a risky manner, observe parents and friends behaving in a risky manner in traffic, and have been exposed as passengers to risky driving more often take risks in traffic themselves. These results provide support for including items on risky road behavior in health monitors and to design interventions that address the risk factors in the child’s perceived social environment.     

Other high-risk factors for young drivers--how graduated licensing does,doesn't,or could address them

PROBLEM: Young drivers, particularly those who are newly licensed, have a very high crash risk. This paper examines the risk factors underlying their high crash rates and assesses the extent to which existing graduated licensing programs address these risks and whether improvements to these programs should be considered. METHOD: Review and synthesis of the literature. RESULTS: The elevated risk among young drivers of being in an injury crash is the result of a number of factors found alone or in combination, such as risky driving, alcohol use, seat belt nonuse, driver distraction, fatigue, and vehicle choice. Nighttime and passenger restrictions, adopted widely in the United States, work by keeping drivers out of hazardous situations rather than by addressing risk factors directly. However, the risk factors remain in play in driving situations not specifically restricted by law. Although other graduated licensing components adopted around the world-more stringent exit tests (i.e., you need to pass a test to move to the next stage), hazard perception tests, and restrictions on speed, vehicle power, and roadway access-make sense based on the identified risk factors, they are not yet supported by research. Should research findings warrant it, consideration should be given to providing guidance to parents about how to keep their beginning drivers safe, including information on vehicle choice. IMPACT ON RESEARCH, PRACTICE, AND POLICY: Researchers should continue to monitor and to evaluate innovative approaches to reduce the crash risk of young drivers. The effectiveness of new approaches should be established before adoption on a wider scale takes place.     

Young females' attention toward road safety images: An ERP study of the revised reinforcement sensitivity theory

Objective: This study examined whether reward and punishment sensitivities, as conceptualized by Gray and McNaughton's revised reinforcement sensitivity theory (RST), influenced young female drivers' attention toward a series of positive and negative antispeeding advertisement images. Young females' increasing crash risk is associated with their engagement in risky behaviors, which, in turn, has been associated with a stronger behavioral approach system (BAS; sensitive to rewards). It was predicted that individuals with a stronger BAS would elicit larger N100 and N200 mean amplitudes (reflecting greater attention) toward the positive images. Similar associations were predicted in relation to the fight–flight–freeze system (FFFS; sensitive to punishments) for negative images.

Method: Twenty-four female drivers (17–25 years; final N = 16) completed Corr-Cooper's RST-Personality Questionnaire, prior to undergoing an event-related potential computerized visual task (i.e., oddball paradigm) that included positive, negative, and neutral images as targets against checkerboard image distractors.

Results: Contrary to expectations, individuals with a stronger BAS (Reward Reactivity and Impulsivity) demonstrated significantly larger N200 mean amplitudes at the Cz electrode site on presentation of the negative images than those with a weaker BAS. No other significant RST effects were found.

Conclusions: These findings provide some preliminary objective support for the use of negative emotion-based road safety advertisements for young females. Further, this study provides support for using psychophysiological measures to enhance understanding of traffic injury persuasion.     

Deprived neighborhoods and risk of road trauma (incidence and severity) among under 25year-olds in the Rhône Département (France)

Introduction

Previous research has shown that there are inequalities with regard to traffic accident risk between different social categories. This study describes the influence of the type of residential municipality (with or without deprived urban areas, “ZUS, zones urbaines sensibles”), used as an indicator of contextual deprivation, on the incidence and severity of road trauma involving people of under 25 years of age in the Rhône.

Method

Injury data were taken from The Rhône Road Trauma Registry. The study covers the 2004–2007 period, with 13,589 young casualties. The incidence of traffic injury of all severities were computed according to the type of municipality and the age, gender, and type of road user. The ratios of the incidences of deprived municipalities, compared with others were calculated. Subsequently the severity factors and incidences according to the severity level (ISS 1–8, ISS 9+) were studied.

Results

For the main types of road users except motorized two-wheeler users, the incidences were higher in the deprived municipalities: the greatest difference was for pedestrians, where the incidences were almost twice those of other municipalities. This excess risk, constituting a health inequality topic rarely considered, was even greater in municipalities with two or three ZUSs. It was essentially observed for minor injuries among motorists, cyclists, and pedestrians.

Conclusions

While the incidence increased among people less than 25 years of age, the severity of road injuries was lower in deprived neighborhoods, contrary to what is suggested by other studies. This lower severity disappeared when taking into account the crash characteristics.

Impact on industry

The incidence of injuries as a pedestrian, cyclist or motorist is higher among young people living in deprived municipalities. These areas should therefore be the targets of dedicated education programs, as well as further investigations about urban planning.     

Recent developments in young driver education, training and licensing in Australia

Australian young driver education and training approaches have differed from the mandatory school-based programs found internationally; generally comprising voluntary programs conducted outside of licensing. This paper reports on recent developments pertaining to the pre-learner, learner, and provisional license stages. Given its important context, state-based graduated driver licensing systems are also reviewed. There has been a shift toward starting driver education younger (pre-learner), greater involvement of parents, and more school-based programs; many now conducted by licensing authorities. The majority of initiatives are yet to be evaluated, particularly relative to crash outcomes; however, some studies suggest other positive outcomes, including increased supervised practice and delayed licensure. Furthermore, the federal government is proceeding with plans for a national license-based program. Several jurisdictions have also announced the introduction of passenger and nighttime restrictions on provisional licenses. Together these initiatives offer promise of reductions in young driver-related fatalities and injuries in the very near future.     

Are helmet laws protecting young motorcyclists?

PROBLEM: The trend in state mandatory motorcycle helmet laws is away from universal coverage to partial coverage statutes that require only young riders to wear a helmet. Among partial coverage states substantial variation exists in this age requirement. How effective are motorcycle helmet laws at reducing young motorcyclist fatalities? METHOD: The dependent variable is the number of motorcyclist fatalities 15-20 years of age. Fixed effects negative binomial regression models are estimated using panel data for all 50 states and Washington DC, for the period 1975-2004. RESULTS: Universal helmet laws are associated with fatality rates that are 31% lower among motorcyclists 15-20 years of age. In contrast, partial coverage laws targeting young motorcyclists are statistically unrelated to a reduction in the fatality rates of this age group. DISCUSSION: The long-term consequence of the move away from universal helmet laws will be an increased level of risk faced by young motorcyclists. In many states, mandatory motorcycle helmet laws are not protecting even young riders.     

Parents’ work injuries and children’s mental health: The moderating role of children’s work centrality

Introduction: The purpose of this study is to explore the relationship between parents’ work-related injuries and their children’s mental health, and whether children’s work centrality – the extent to which a child believes work will play an important part in their life – exacerbates or buffers this relationship. Method: We argue that high work centrality can exacerbate the relationship between parental work injuries and children’s mental health, with parental work injuries acting as identity-threatening stressors; in contrast, high work centrality may buffer this relationship, with parental work injuries acting as identity-confirming stressors. We test this relationship with a sample of Canadian children (N = 4,884, 46.2% female, M age = 13.67 years). Results:Children whose parents had experienced more frequent lost-time work-related injuries reported worse mental health with high work centrality buffering this negative relationship. Conclusions: Our study highlights the vicarious effects of work injuries on salient others, specifically parental work injuries on children’s mental health, as well as the role of work centrality in shaping children’s sense-making and expectations about the consequences of work.     

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.
