Assessing road rage victimization and perpetration in the Ontario adult population: the impact of illicit drug use and psychiatric distress

The problem of correlation between the concepts of "violent" and "dangerous driving" in modern national and foreign psychology

At present people in nearly all the countries of the world confront with the problem of "aggressive driving", which is particularly acute in the cities. The concept of "aggressive driving" exists in many countries of the world. But there are some differences in approaches to the definition of the content of this notion, which results in giving different names for this kind of driving. For example, in most European countries, as well as in some Asian countries people use the terms "careless driving" and "dangerous driving" ("dangerous driving"). In the United States and Australia a broader concept like "aggressive behaviour on the road" is in use. In foreign countries, there are laws and rules of the road, according to which "aggressive" driving is punishable by a fine, and in some cases, even carries criminal penalties. In Russia, the problem of "aggressive driving" nowadays has started to be treated at the legislative level, and on May, 2016 the Government of the Russian Federation enacted a regulation No. 477 “On amending the road traffic regulations of the Russian Federation ", which introduced the concept of "dangerous driving ", and on 08.06.16 the “Law on dangerous driving” was adopted. The term "dangerous driving" is not easy for understand and it raises questions among drivers, who are not completely aware of what exactly is considered to be "dangerous driving" and how to implement this notion in practice. This article provides an overview of current foreign and national researches, concerning the problem of "aggressive" and "dangerous driving", identifies the differences and similarities between the concepts of "aggressive" and "dangerous driving" as they are understood in Russia and abroad, and describes the factors that influence the emergence of aggression in drivers

Traumatic brain injury, driver aggression and motor vehicle collisions in Canadian adults

OBJECTIVE

This study examines the associations between lifetime traumatic brain injury (TBI), driver aggression, and motor vehicle collisions among a population sample of adults who reside in the province of Ontario, Canada.

METHOD

A cross-sectional sample of 3993 Ontario adults, aged 18-97 were surveyed by telephone in 2011 and 2012 as part of Center for Addiction and Mental Health's ongoing representative survey of adult mental health and substance use in Canada. TBI was defined as trauma to the head that resulted in loss of consciousness for at least five minutes or overnight hospitalization.

RESULTS

An estimated 91% (95% CI: 90.0, 91.9) of individuals in this sample held a valid Ontario driver's license at the time of testing. Among those, 16.7% reported a history of lifetime TBI and 83.3% reported no TBI. The prevalence of TBI was higher among men than women. Relative to licensed adults without TBI, adults with a history of TBI had significantly higher odds of engaging in serious driver aggression in the past 12 months, such as making threats to hurt another driver, passenger or their vehicle (AOR=4.39). These individuals also reported significantly higher odds (AOR=1.74) of being involved in a motor vehicle collision that resulted in hurting themselves, their passenger(s) or their vehicle.

CONCLUSION

This is the first population-based study to demonstrate a relationship between a history of TBI and higher rates of serious driver aggression and collision involvement. Given the large proportion of adult drivers with a history of TBI, these individuals may account for a disproportion burden of all traffic safety problems. Whether the increased road safety risk of adults with a history of TBI is reflective of neurocognitive deficits or is merely evidence of a cluster of unsafe activities produced by a higher risk lifestyles requires further research attention.

The impact of childhood symptoms of conduct disorder on driver aggression in adulthood

BACKGROUND

Despite limited empirical investigation, existing scientific literature suggests that individuals with a history or current diagnosis of conduct disorder (CD) may be more likely to demonstrate reckless and aggressive driving. Much of the limited research in this field examines the impact of childhood CD on driver behaviour and collision risk in young adults. Few if any, studies assess the impact of this disorder on driver behaviour beyond age 21 years. The current research is a population-based study of the impact of CD symptoms during childhood on the risk of engaging in driver aggression during adulthood.

METHODS

Data are based on telephone interviews with 5230 respondents who reported having driven in the past year. Data are derived from the 2011-2013 cycles of the CAMH Monitor, an ongoing cross-sectional survey of adults in Ontario, Canada aged 18 years and older. A binary logistic regression analysis of self-reported driver aggression in the previous 12 months was conducted, consisting of measures of demographic characteristics, driving exposure, problem substance use, alcohol- and drug-impaired driving, symptoms of attention deficit hyperactivity disorder, and childhood (before age 15) symptoms of CD.

RESULTS

When entered with demographic characteristics, driving exposure, and other potential confounders, childhood symptoms of CD increased the odds of reporting driver aggression more than two-fold (adjusted OR=2.12). Exploratory analyses of the interaction between childhood symptoms of CD and age was not a significant predictor of driver aggression.

CONCLUSIONS

Results suggest that symptoms of CD during childhood are associated with significantly increased odds of self-reported driver aggression during adulthood. Limitations and future directions of the research are discussed.

Addressing Driver Aggression

Aggressive roadway behavior contributes to motor-vehicle collisions, resulting in significant injuries, fatalities, and related financial costs. Psychological models have identified person- and situation-related variables that are predictive of driver aggression, and these have been used to develop strategies to alleviate aggressive roadway behavior. Future psychological research directions are discussed.

Road rage among drug dependent patients

The consumption of alcohol, cocaine and cannabis is associated with aggressive behaviour, being a victim of injuries from various causes, and suffering traffic accidents. On the other hand, there is a significant association between road rage and traffic accidents, yet this has not been studied in persons suffering a substance dependence disorder. This study analyses the prevalence of road rage in substance dependent patients undergoing treatment. 100 patients randomly selected at an outpatient treatment centre were included in the study. 63% of the patients had experienced road rage in the year prior to the interview, and 18% were serious perpetrators. There was a higher frequency among drivers and those who were starting treatment for cocaine and cocaine+heroin. The study shows that road rage is very frequent among patients with disorders due to substance dependence who are undergoing treatment, in particular the most severe form ("serious perpetrators"). Special attention should be addressed to the issue of driving and road rage during the treatment of these patients.

Driving frequency and Its impact on road rage offending and victimization: a view from opportunity theory

Road rage has been described as a key criminal justice and public health concern. Although research attention to this issue has expanded dramatically, most of this work has focused on the identification of predisposing individual factors. It is equally important to begin to assess those factors that may modify the likelihood of road rage including the broader structural opportunities that are connected with the propensity to be involved in a road rage incident. Drawing on opportunity theory, this article examines whether there is a relationship between increased opportunities to be involved in road rage and an increased likelihood of being a road rage victim or offender. The analysis is further extended to specifically test whether this relationship is linear, thereby examining the applicability of the opportunity saturation hypothesis. Using data from the Centre for Addiction and Mental Health (CAMH) Monitor, our findings support both the application of opportunity theory to understanding road rage and the presence of opportunity saturation. Although a clear relationship exists between kilometers driven and experiences of road rage, evidence emerged suggesting there may be a threshold whereby increased opportunities for road rage do not lead to road rage behavior.

Does gender moderate the relationship between driver aggression and its risk factors?

AIM

The current study assessed gender as a potential moderator of the relationship between self-reported driver aggression and various demographic variables, general and driving-related risk factors.

METHODS

Using data from a general-population telephone survey conducted from July 2002 through June 2005, two approaches to binary logistic regression were adopted. Based on the full dataset (n=6259), the initial analysis was a hierarchical-entry regression examining self-reported driver aggression in the last 12 months. All demographic variables (i.e., gender, age, income, education, marital status), general risk factors (i.e., psychological distress, binge drinking, cannabis use), and driving-related risk factors (i.e., driving exposure, stressful driving, exposure to busy roads, driving after drinking, driving after cannabis use) were entered in the first block, and all two-way interactions with gender were entered stepwise in the second block. The subsequent analysis involved dividing the sample by gender and conducting logistic regressions with main effects only for males (n=2921) and females (n=3338) separately.

RESULTS

Although the prevalence of driver aggression in the current sample was slightly higher among males (38.5%) than females (32.9%), the difference was small, and gender did not enter as a significant predictor of driver aggression in the overall logistic regression. In that analysis, difficulty with social functioning and being older were associated with a reduced risk of driver aggression. Marital status and education were unrelated to aggression, and all other variables were associated with an increased risk of aggression. Gender was found to moderate the relationships between driver aggression and only three variables: income, psychological distress, and driving exposure. Separate analyses on the male and female sub-samples also found differences in the predictive value of income and driving exposure; however, the difference for psychological distress could not be detected using this separate regression approach. The secondary analysis also identified slight differences in the predictive value of four of the risk factors, where the odds ratios for both males and females were in the same direction but only one of the two was statistically significant.

CONCLUSIONS

The results demonstrate the importance of conducting the gender analysis using both regression approaches. With few exceptions, factors that were predictive of driver aggression were generally the same for both male and female drivers.

Driving citations and aggressive behavior

BACKGROUND

Anger and driving have been examined in a number of studies of aggressive drivers and in drivers with road rage using various psychological and environmental study variables. However, we are not aware of any study that has examined the number of driving citations (an indication of problematic driving) and various forms of anger not related to driving.

METHOD

Using a cross-sectional approach in a consecutive sample of 331 respondents (68% female), we surveyed participants about the number of past driving citations, not necessarily convictions, and 21 aggressive behaviors using the Aggressive Behavior Questionnaire.

RESULTS

The number of driving citations demonstrated a statistically significant correlation with the number of aggressive behaviors in the 21-item Aggressive Behavior Questionnaire. There were no differences between men and women. As for specific aggressive behaviors, the number of driving citations was statistically significantly related to punching a wall when angry, causing and getting into a bar fight, getting into fistfights (not in a bar), causing someone to have an accident, and intentionally running someone off the road.

CONCLUSIONS

The number of driving citations, an indication of problematic driving, appears to be related to generally aggressive behavior. Findings indicate that if aggression plays a role in problematic driving, it is likely not limited to the road.

Road rage: relationships with borderline personality and driving citations

OBJECTIVE

The objectives of this study were to determine: (1) the prevalence of self-reported road rage in a primary care sample; (2) the relationship, if any, between road rage and borderline personality disorder (BPD); and (3) whether those with road rage have a greater prevalence of different types of driving citations compared to those without road rage.

METHOD

Using a consecutive, cross-sectional sample of primary care outpatients, we surveyed 419 individuals.

RESULTS

The prevalence of self-reported road rage in this sample was 35.3%. BPD was significantly more prevalent among participants with road rage (24.8% vs. 9.8%). Compared to those without road rage, those with road rage reported statistically significantly higher numbers of different types of driving citations, including moving and non-moving violations, as well as having had a driver's license suspended. There were no differences between the groups with regard to vehicular crashes or driving while intoxicated.

CONCLUSIONS

About one-third of individuals reported road rage. The prevalence of BPD was significantly higher among those with road rage compared to those without road rage, and is likely to be one of the contributory variables to reckless driving. Individuals who reported road rage appear to be less disciplined drivers and are subject to more types of driving citations, although they do not report greater rates of vehicular crashes or driving while intoxicated.

Road Rage: What's Driving It?

Up to one-third of community participants report being perpetrators of road rage, indicating that various forms of road rage are relatively commonplace. However, only two percent or less of incidents culminate in serious damage to persons or vehicles. The most common offenders appear to be young and male. A number of factors may contribute to road rage, including environmental factors (e.g., greater number of miles driven per day, traffic density), nonspecific psychological factors (e.g., displaced aggression, attribution of blame to others), and bona fide Axis I and II disorders. The most common Axis I disorders appear to be related to alcohol and substance misuse, whereas possible Axis II disorders include borderline and antisocial personality disorders. Being aware of these contributory factors to road rage may improve general clinical awareness of the nature and treatment of perpetrators.

Road rage victimization among adolescents

PURPOSE

Although much has been learned about road rage among adults, data on road rage experiences among adolescents has not been available previously. We examine the prevalence and demographic correlates of road rage victimization based on a population survey of Ontario students.

METHODS

Based on the 2005 Ontario Student Drug Use Survey, a self-administered survey of Ontario students in grades 7-12 (n = 7726), the contribution of demographic factors (gender, region, driver's license status, grade, overall marks) to three road rage victimization measures was examined with logistic regression analysis.

RESULTS

Just over half of students (53.2%) had been victims of shouts, curses and rude gestures in the past year, 8.9% were threatened with damage to their vehicle or personal injury and 6.2% experienced an attempt or actual damage to their vehicle or personal injury. Logistic regression analyses revealed that being a victim of shouting was significantly related to region, driver's license status, and grade. Victimization by threats was significantly related to gender, driver's license, grade, and marks. Being a victim of attempts or actual vehicle damage or injury was significantly related to region, driver's license, and marks.

CONCLUSION

This study provides the first indication of prevalence of road rage victimization among adolescents. Road rage victimization in its milder form is common, involving just over half of Ontario students in grades 7-12. About 1 in 10 students were threatened with vehicle damage or personal injury, and about 1 in 20 were victims of attempts or actual damage or injury.
