Hyperactive children as young adults: driving abilities, safe driving behavior, and adverse driving outcomes.

ADHD has been linked to poorer driving abilities and greater adverse outcomes (crashes, citations) in clinic-referred cases of teens and adults with ADHD. No study, however, has focused systematically on ADHD children followed into adulthood. The present paper does so while measuring driving-related cognitive abilities, driving behavior, and history of adverse driving outcomes. A multi-method, multi-source battery of driving measures was collected at the young adult follow-up on hyperactive (H; N=147; mean age=21.1) and community control children (CC; N=71; mean age=20.5) followed for more than 13 years. More of the H than CC groups had been ticketed for reckless driving, driving without a license, hit-and-run crashes, and had their licenses suspended or revoked. Official driving records found more of the H group having received traffic citations and a greater frequency of license suspensions. The cost of damage in their initial crashes was also significantly greater in the H than CC group. Both self-report and other ratings of actual driving behavior revealed less safe driving practices being used by the H group. Observations by driving instructors during a behind-the-wheel road test indicated significantly more impulsive errors. Performance on a simulator further revealed slower and more variable reaction times, greater errors of impulsiveness (false alarms, poor rule following), more steering variability, and more scrapes and crashes of the simulated vehicle against road boundaries in the H than in the CC group. These findings suggest that children growing up with ADHD may either have fewer driving risks or possibly under-report those risks relative to clinic-referred adults with this disorder. Deficits in simulator performance and safe driving behavior, however, are consistent with clinic-referred adults with ADHD suggesting ongoing risks for such adverse driving outcomes in children growing up with ADHD.

Identifying factors that predict persistent driving after drinking, unsafe driving after drinking, and driving after using cannabis among young adults.

UNLABELLED: The main aim of this study was to identify adolescent/young adulthood factors that predicted persistent driving after drinking, persistent unsafe driving after drinking, and persistent cannabis use and driving among young adults. It was a longitudinal study of a birth cohort (n=933, 474 males and 459 females) and was based on data collected at ages 15, 18, 21 and 26 years. At each of these ages members of the cohort attended the research unit for a personal interview by a trained interviewer, using a standardised questionnaire. For this study, the data for the outcome measures (persistent driving after drinking, persistent unsafe driving after drinking, and persistent driving after using cannabis) were obtained at ages 21 and 26 years. The main explanatory measures were collected at ages 15, 18, 21 years and included demographic factors (academic qualifications, employment, parenting); personality measures; mental health measures (substance use, cannabis dependence, alcohol dependence, depression); anti-social behaviour (juvenile arrest, aggressive behaviour, court convictions); early driving behaviour and experiences (car and motorcycle licences, traffic crashes). The analyses were conducted by gender. The results showed that females who persisted in driving after drinking (13%, n=61) were more likely than the others to have a motorcycle licence at 18. The males who persisted in driving after drinking (28%, n=135) were more likely than the other males to have some school academic qualifications and to be employed at age 26. Compared to the other males, those who persisted in unsafe driving after drinking (4%, n=17) were more likely to be aggressive at 18 and alcohol dependent at 21. Only six (1%) females persisted in unsafe driving after drinking so regression analyses were not conducted for this group. For persistent driving after using cannabis, the univariate analyses showed that females who persisted with this behaviour tended to have high substance use at 18, cannabis dependence at 21, police contact as a juvenile, and to be a parent at 21. For this group, because of the small numbers (3%, n=13) multivariate analyses were not appropriate. For the males who persisted in driving after using cannabis (14%, n=68) a wide range of variables were significant at the univariate stage. The multivariate analysis showed that the most important factors were dependence on cannabis at 21, at least one traffic conviction before 21, a non traffic conviction before 18, and low constraint at 18. CONCLUSION: These results show different characteristics were associated with persistence in each of these outcome behaviours. This indicates that different approaches would be required if intervention programmes were to be developed to target these behaviours.

The "genetics" of driving behavior: parents' driving style predicts their children's driving style.

It can be hypothesized that children inherit their parents' driving habits both through genetic disposition and model learning. A few studies have shown indeed that parents' and their children's traffic convictions and accidents correlate which, however, may be due to life style and other exposure factors. This study aimed at investigating the relationships between parents' and their children's self-reported driving behavior. The subjects were 174 parent-child pairs who independently completed a questionnaire. Driving behavior-driving style-was evaluated by means of Manchester driver behavior questionnaire (DBQ), while data about driving exposure, life style, accidents, and traffic tickets were also collected. A series of regression models indicated that parents' self-reported driving behavior explains their children's respective self-reported behavior, even when exposure and demographic and life-style factors are controlled.

[Driving a vehicle--driving a motor vehicle, a necessary differentiation for proven limit of alcohol-induced absolute driving incapacity].

There are special cases of vehicle driving, such as driving or moving a certain type of vehicle without an engine as part of the division of labour. These cause distinguishing problems in the area of paragraphs 21, 24, 25 StVG and 44, 69, 69 b, 315 c, 316 StGB with consequences for the type and extent of the proof of dangerous driving due to alcohol. From the jurisdiction so far published on this topic, relevant limiting criteria will be summarised and clearly laid out.

Drinking-driving as a component of problem driving and problem behavior in young adults.

OBJECTIVE: This study replicated and extended a conceptual model of drinking-driving and its relationship to other problem behavior to determine (1) if the model characterized the problem driving and problem behavior of young adults from the general population and (2) if the model applied to women as well as to men. METHOD: Telephone survey data (measures of drinking-driving, drug-driving, risky driving, problem drinking, drug use and delinquent behavior) collected from young adults (N = 4,230, 53% female) were used in structural equation modeling. Two models were developed--one for problem driving and one for problem behavior--each testing the structural associations among latent variables and testing them as latent indicators of common second-order latent variables. RESULTS: The results supported the hypothesis that drinking-driving (along with problem drinking, drug use and delinquent behavior) is an indicator of problem behavior in the general population sample. Also, drinking-driving, drug-driving and risky driving were demonstrated to be indicators of a common construct: problem driving. The models fit the data equally well for both young men and young women, and a crossvalidation conducted on an independent sample confirmed the results. CONCLUSIONS: The results provide empirical support for the inclusion of drinking-driving and problem driving in an extended model of Problem Behavior Theory. Drinking-driving, drug-driving and risky driving all relate to a common construct: problem driving. These results have important implications for research and for interventions to treat or prevent drinking-driving, especially among young adults.

Self-regulation of driving and its relationship to driving ability among older adults.

Although it is known that older drivers limit their driving, it is not known whether this self-regulation is related to actual driving ability. A sample of 104 older drivers, aged between 60 and 92, completed a questionnaire about driving habits and attitudes. Ninety of these drivers also completed a structured on-road driving test. A measure of self-regulation was derived from drivers' self-reported avoidance of difficult driving situations. The on-road driving test involved a standard assessment used to determine fitness to drive. Driving test scores for the study were based on the number of errors committed in the driving tests, with weightings given according to the seriousness of the errors. The most commonly avoided difficult driving situations, according to responses on the questionnaire, were parallel parking and driving at night in the rain, while the least avoided situation was driving alone. Poorer performance on the driving test was not related to overall avoidance of difficult driving situations. Stronger relationships were found between driving ability and avoidance of specific difficult driving situations. These specific driving situations were the ones in which the drivers had low confidence and that the drivers were most able to avoid if they wished to.

Driving after stroke: driving exposure, advice, and evaluations.

OBJECTIVE: Little is known about the extent to which stroke survivors return to driving and the advice and/or evaluations they receive about driving. This study sought to estimate the prevalence of driving after stroke and to determine whether stroke survivors receive advice and evaluation about driving. DESIGN: A convenience sample of stroke survivors was surveyed regarding driving status following stroke, driving exposure, advice received about driving, and evaluation of driving performance. PARTICIPANTS: Two hundred ninety stroke survivors who were between 3 months to 6 years poststroke. RESULTS: Thirty percent of stroke survivors who drove before the stroke resumed driving after the stroke. Stroke survivors are often poorly informed by health care professionals about driving, with 48% reporting that they did not receive advice about driving and 87% reporting that they did not receive any type of driving evaluation. Almost one third of poststroke drivers had high exposure, driving 6 to 7 days per week and/or 100 to 200 miles per week. CONCLUSIONS: These findings suggest that many stroke survivors are making decisions about their driving capabilities without professional advice and/or evaluation. The results also suggest that rehabilitation professionals need to devote more attention and resources to driving issues when working with stroke survivors and their families.

P-drive: assessment of driving performance after stroke.

OBJECTIVE: To investigate aspects of validity and stability of Performance Analysis of Driving Ability (P-Drive), for people with stroke when used in a driving simulator. DESIGN: A cross-sectional observational study. SUBJECTS: The study included a consecutive series of 101 participants with stroke referred for evaluation or selected from a stroke registry. METHODS: P-Drive was used to observe driving performance in order to assess driving ability. P-Drive comprises 20 items assessing the quality of the participant's driving performance. Aspects of validity and reliability in P-Drive were evaluated using Rasch statistics. RESULTS: The items (95%) and participants (97%) demonstrated acceptable goodness-of-fit and met statistical expectations according to the Rasch model. The results support internal scale validity and person response validity. P-Drive could separate the participants with different driving abilities and the standard errors were within reasonable criteria for drivers with a moderate-to-low ability to drive. CONCLUSION: The findings from this study indicated that P-Drive is an assessment tool with properties of internal scale validity, person response validity, and which also contains aspects of reliability in relation to precision of the estimates and separation. P-Drive seems to be a valid and stable assessment tool for assessing the driving ability in a simulator of people with stroke.

Virtually driving: are the driving environments "real enough" for exposure therapy with accident victims? An explorative study.

There is a small but growing body of research supporting the effectiveness of computer-generated environments in exposure therapy for driving phobia. However, research also suggests that difficulties can readily arise whereby patients do not immerse in simulated driving scenes. The simulated driving environments are not "real enough" to undertake exposure therapy. This sets a limitation to the use of virtual reality (VR) exposure therapy as a treatment modality for driving phobia. The aim of this study was to investigate if a clinically acceptable immersion/presence rate of >80% could be achieved for driving phobia subjects in computer generated environments by modifying external factors in the driving environment. Eleven patients referred from the Accident and Emergency Department of a general hospital or from their General Practitioner following a motor vehicle accident, who met DSM-IV criteria for Specific Phobia-driving were exposed to a computer-generated driving environment using computer driving games (London Racer/Midtown Madness). In an attempt to make the driving environments "real enough," external factors were modified by (a) projection of images onto a large screen, (b) viewing the scene through a windscreen, (c) using car seats for both driver and passenger, and (d) increasing vibration sense through use of more powerful subwoofers. Patients undertook a trial session involving driving through computer environments with graded risk of an accident. "Immersion/presence" was operationally defined as a subjective rating by the subject that the environment "feels real," together with an increase in subjective units of distress (SUD) ratings of >3 and/or an increase of heart rate of >15 beats per minute (BPM). Ten of 11 (91%) of the driving phobic subjects met the criteria for immersion/presence in the driving environment enabling progression to VR exposure therapy. These provisional findings suggest that the paradigm adopted in this study might be an effective and relatively inexpensive means of developing driving environments "real enough," to make VR exposure therapy a viable treatment modality for driving phobia following a motor vehicle accident (MVA).

Self-rated driving performance among elderly drivers referred for driving evaluation.

PURPOSE: To explore whether elderly drivers of varying driving skill levels (1) differ in their perception of their driving evaluation performance and (2) determine if self-rated driving evaluation performance is related to cognitive ability. METHODS: One hundred and fifty-two drivers aged 65 years or older and referred for a driving evaluation were enrolled into the study. Subjects were asked the question, "how well do you think you will perform today on your driving evaluation compared to others your own age?" Subjects also completed the Mini-Mental State Exam and a 30-min drive on a STISIM Drivetrade mark simulation (Systems Technology, Inc., Hawthorne, CA). Only 47 subjects completed both the simulated drive and self-rated item. RESULTS: Sixty-five percent of drivers rated themselves as performing better on a driving test than others of their age. Another 31.9% felt they would perform the same as others of their age on a driving test. A 50.0% of those considering themselves "a little better" and 52.9% of those considering themselves "a lot better" had an unsafe driving performance. As self-rated driving evaluation performance increased, there was a significantly increased risk of unsafe driving (p=0.02) in the study population. Drivers who considered themselves at least a little better than others of their age were over four times more likely to be unsafe drivers compared to others who believed they were comparable to or worse than other drivers of their age (RR=4.13, 95% CI=1.08-15.78). There was no significant difference in MMSE between self-rating groups (p=0.76). CONCLUSION: Older drivers assign high ratings to their driving performance, even in the presence of suspected skill decline. Cognitive ability was not related to self-rated driving evaluation performance.

Do parent-imposed delayed licensure and restricted driving reduce risky driving behaviors among newly licensed teens?

Motor vehicle crashes are the leading cause of death and injury to teenagers. Crash risks result from their age, inexperience, and risky driving. The purpose of this study was to determine whether parent-imposed delayed licensure and restricted driving are related to fewer teenage risky driving behaviors. At baseline, 275 teenagers with a learner's permit and one of their parents were interviewed about driving attitudes and teenage behaviors. One year later, 161 of the teenagers had since obtained a provisional license and were reinterviewed about time of licensure, parental restrictions on driving, and driving attitudes and behaviors. The results indicated that parents delayed licensure until teens were "ready," and limited their driving in terms of trip and risk conditions. Higher levels of risky driving behaviors were predicted by younger ages at licensure and fewer limits on driving in the first month, in addition to male gender, higher conflict over driving, lower perceptions of dangers related to driving, more problem behaviors at baseline, and more high-risk driving (e.g., at night, teenage passengers). Overall, the results indicate that a combination of being older at licensure and restricting driving under high-risk conditions at licensure may be an effective way to curb teens' risky driving behaviors.

Personal and situational influences on drink driving and sober driving among a cohort of young adults.

OBJECTIVES: To compare personal and situational influences on incidents involving drink driving with those involving sober driving. METHODS: Information on a range of road safety practices was sought in face to face interviews conducted with 969 members of the Dunedin Multidisciplinary Health and Development Study cohort at age 26 years. A total of 750 study members reported an incident that involved the opportunity to consume alcohol and also travel by motor vehicle. Of these, 87 were classified as "drink drive incidents" and 663 as "sober drive incidents". RESULTS: Study members who were male, of lower socioeconomic status, had no school qualifications, or were dependent on alcohol or marijuana at age 21 were significantly more likely to report a drink drive incident at age 26. Compared with the sober drive incidents, the drink drive incidents were more commonly associated with driving alone, drinking at bars, and no advanced planning. For drink drive incidents the amount of alcohol consumed was influenced by the conviviality of the occasion, whereas for sober drive incidents it was the need to drive. One quarter of those reporting drink drive incidents stated they had used marijuana and/or LSD at the event at which they drank. CONCLUSIONS: Drink drive and sober drive incidents differed, particularly with regard to decisions made before the event. Prevention efforts could usefully be targeted toward these decisions.

The effect of visual field defects on driving performance: a driving simulator study.

OBJECTIVES: To investigate the effect of visual field defects on driving performance, and to predict practical fitness to drive. METHODS: The driving performance of 87 subjects with visual field defects due to ocular abnormalities was assessed on a driving simulator and during an on-road driving test. OUTCOME MEASURES: The final score on the on-road driving test and simulator indexes, such as driving speed, viewing behavior, lateral position, time-headway, and time to collision. RESULTS: Subjects with visual field defects showed differential performance on measures of driving speed, steering stability, lateral position, time to collision, and time-headway. Effective compensation consisted of reduced driving speed in cases of central visual field defects and increased scanning in cases of peripheral visual field defects. The sensitivity and specificity of models based on vision, visual attention, and compensatory viewing efficiency were increased when the distance at which the subject started to scan was taken into account. CONCLUSIONS: Subjects with visual field defects demonstrated differential performance on several driving simulator indexes. Driving examiners considered reduced speed and increased scanning to be valid compensation for central and peripheral visual field defects, respectively. Predicting practical fitness to drive was improved by taking driving simulator indexes into account.

Driving scenes test of the Neuropsychological Assessment Battery (NAB) and on-road driving performance in aging and very mild dementia.

The Driving Scenes test of the new Neuropsychological Assessment Battery (NAB; [Stern, R.A., & White, T. (2003a). Neuropsychological Assessment Battery. Lutz, FL: Psychological Assessment Resources, Inc.]) measures several aspects of visual attention thought to be important for driving ability. The current study examined the relationship between scores on the Driving Scenes test and on-road driving performance on a standardized driving test. Healthy participants performed significantly better on the Driving Scenes test than did very mildly demented participants. A correlation of 0.55 was found between the brief, office-based Driving Scenes test and the 108-point on-road driving score. Furthermore, the Driving Scenes test scores differed significantly across the driving instructor's three global ratings (safe, marginal, and unsafe), and results of a discriminant function analysis indicated that the Driving Scenes test correctly classified 66% of participants into these groups. Thus, the new NAB Driving Scenes test appears to have good ecological validity for real-world driving ability in normal and very mildly demented older adults.

Alzheimer's disease and driving: prediction and assessment of driving performance.

OBJECTIVES: To examine driving competence in a group of drivers diagnosed with probable Alzheimer's Disease (AD) in terms of a standardized open road evaluation and expert judgments. To examine the validity of a standardized medical examination, including administration of the Mini-Mental Status Exam (MMSE), and a standardized neuropsychological assessment as predictors of open road driving performance. DESIGN: A prospective investigation with consecutively referred subjects. SETTING: Coorabel Driver Assessment Centre, Royal Rehabilitation Centre Sydney, Australia. PARTICIPANTS: Nineteen subjects with a diagnosis of probable AD. MEASUREMENTS: A standardized clinical medical examination, a standardized neuropsychological assessment, and a standardized open road driving evaluation. The driving evaluation provided a correct driving actions score. The outcome measure was the expert judges' rating of overall driving competence, which was termed the final on-road result. RESULTS: Seven subjects passed the on-road driving evaluation, and 12 failed. MMSE was found to be a significant predictor of final on-road result. The physician's prediction, the neuropsychology test scores, and the neuropsychologist's prediction were not found to be significantly associated with the final on-road result. The on-road driving evaluation was a reliable test. CONCLUSION: Inasmuch as all subjects except one were still driving and all wished to continue to drive, it is important to note that 63.2% of subjects failed the on-road evaluation. Conversely, 36.8% were judged safe to drive, suggesting that AD diagnosis alone may be insufficient criteria for cessation of driving. A standardized road test may be the only appropriate means of determining driving competence in people diagnosed with AD.

Driving after cerebral ischemia--a driving simulator investigation.

UNLABELLED: Stroke patients with relevant deficits are not allowed to drive. This study tended to assess driving abilities in an early stage after cerebral ischemia with a driving simulator. METHODS: 32 patients (aged 54.9 +/- 14.8 years) with acute ischemia in the middle cerebral artery (MCA) (n = 24) and in the vertebral artery (VA) (n = 8) were investigated with reaction tests and a driving simulator. Controls were 12 healthy volunteers (aged 50.0 +/- 13.9 years). RESULTS: Compared to controls, the accident rate was increased only in patients with MCA-ischemia (2.9 +/- 3.6 vs. 1.3 +/- 1.4, p < 0.05). These patients also had poorer results in the driving simulator (p < 0.05) than patients with VA-ischemia. Driving simulator performance and neuropsychological test results did not correlate. CONCLUSION: All patients had only mild deficits and stated themselves able to drive. We could demonstrate the need to focus on driving skills especially in patients with MCA-infarctions. The driving simulator assesses various physical and neuropsychological functions influencing driving. It may especially be used for expert opinions regarding driving licence. It can also serve as a pre-driver evaluation before on road driving tests.

Driving anger, sensation seeking, impulsiveness, and boredom proneness in the prediction of unsafe driving.

The present study investigated the potential contribution of sensation seeking, impulsiveness, and boredom proneness to driving anger in the prediction of aggressive and risky driving. Two hundred and twenty-four college student participants completed measures of trait driving anger, aggressive and risky driving, driving anger expression, sensation seeking, impulsiveness, and boredom proneness. Findings provided additional support for the utility of the Driving Anger Scale (DAS; Deffenbacher, J.L., Oetting, E.R., Lynch, R.S., Development of a driving anger scale, Psychological Reports, 74, 1994, 83-91.) in predicting unsafe driving. In addition, hierarchical multiple regression analyses demonstrated that sensation seeking, impulsiveness, and boredom proneness provided incremental improvements beyond the DAS in the prediction of crash-related conditions, aggressive driving, risky driving, and driving anger expression. Results support the use of multiple predictors in understanding unsafe driving behavior.
