Risky driving and lifestyles in adolescence.
Bina M; Graziano F; Bonino S. Accident Analysis and Prevention 38(3): 472-481, 2006. (60 refs.)
Several studies have shown that risky driving is especially prevalent among young drivers and recent research has pointed out that driving in adolescence should be investigated in the more general context of adolescent development. The first aim of this contribution was to analyze involvement in risky driving in a normative sample of 645 Italian adolescents, boys and girls, aged 14-17, through a self-report questionnaire. A second aim was to evaluate the association between risky driving and lifestyle, defined as involvement in other health risk behaviors and leisure activities. The main results showed that many adolescents drove cars and motorcycles without the required driving license and the most frequent offences were speeding and failure to maintain a safe braking distance. Gender and age differences were also investigated. Results concerning the association between risky driving and lifestyle showed that risky driving was not an isolated behavior. Boys who displayed risky driving practices were more likely to adopt a lifestyle characterized by high involvement in antisocial behaviors, tobacco smoking, comfort eating and time spent in non-organized activities with friends. Girls involved in risky driving were more likely to be involved in other risk-taking behaviors, antisocial behaviors and drug use. Copyright 2006, Elsevier Science Ltd.
Gender differences among young drivers in the association between high-risk driving and substance use/environmental influences.
Elliott MR; Shope JT; Raghunathan TE; Waller PF. Journal of Studies on Alcohol 67(2): 252-260, 2006. (36 refs.)
Objective: The primary aim of this article is to assess young drivers' gender differences in the associations between substance use/environmental influences and high-risk driving behavior. Method: We determine the association of 12th-grade self-reported substance use/environmental influences with high-risk driving behavior as quantified by the number of offenses, serious offenses, crashes, and single-vehicle crashes on state driving records during subjects' (N = 3,607; 51% male) first 4 years of licensure. Results: The associations between high-risk driving and substance use/environmental influences were generally stronger among women than among men. When matched by substance-use profiles, women had fewer risky-driving incidents than men. Conclusions: The results indicate that young women who exhibit high-risk driving behavior deviate more from the general population of young women with respect to alcohol use, alcohol misuse, and marijuana use than high-risk-driving young men differ from other young men. In addition, findings indicate that even if young men and women were to eventually have equal levels of substance use, women would likely retain their lower-risk driving profiles. These findings suggest the need for (1) future research to understand the differential associations, and (2) prevention programs that consider these gender differences.

Evaluation of the Texas 0.08 BAC law.
Gorman DM; Huber JC; Carozza SE. Alcohol and Alcoholism 41(2): 193-199, 2006. (23 refs.)
Aims: The purpose of the present study was to assess the effects on alcohol-involved traffic crashes and fatalities of the 0.08 blood alcohol concentration (BAC) per se law introduced in the state of Texas in 1999. Method: Data pertaining to alcohol-involved traffic crashes and fatalities were extracted from two datasets: the Fatality Analysis Reporting System (FARS) compiled by the National Highway Traffic Safety Administration (for the period January 1995-September 2002), and the Texas Department of Public Safety (DPS) reports of Alcohol Related Motor Vehicle Traffic Accidents and Casualties (for the period January 1995-December 2000). The data were analysed using time-series methods (ARIMA routines). The effects of the law on all drivers were assessed, along with the effects among gender, racial, and age subgroups and crash location (urban vs rural). Results: Separate time-series analyses were conducted with all alcohol-involved and fatal alcohol-involved crashes from the DPS dataset and fatal alcohol-involved crashes from the FARS dataset as the outcome variables. None of the effects for either the total sample or any of the subgroups analysed was statistically significant (this was true of both the FARS and DPS datasets). Conclusions: While there is a growing body of evidence that indicates that 0.08 BAC laws can be effective in reducing alcohol-involved traffic accidents and fatalities, the present study shows that this was not the case in Texas. Future research should move beyond the simple question of whether or not 0.08 BAC laws 'work' and instead explore in more detail the conditions, such as publicity and enforcement, under which the law does or does not contribute to a decline in alcohol-involved accidents and fatalities.

Small-area variations in conviction rates for DWI: The significance of contextual variables in a Southwestern state.
Kunitz SJ; Delaney HD; Layne LJ; Wheeler DR; Rogers EM; Woodall WG. Accident Analysis and Prevention 38(3): 600-609, 2006. (37 refs.)
Average annual conviction rates (1990-2000) of people arrested for driving under the influence of alcohol in each of New Mexico's 33 counties are described. Conviction rates vary from 58 to 95%. Rates are correlated with political conservatism, being higher where a higher proportion of voters voted for the republican presidential candidates, and with measures of crowding in the courts. Conviction rates are higher in rural than urban areas and are correlated with a low prevalence of alcohol-related problems in the population. The variance in conviction rates is higher in rural than urban areas, and higher where measures of court crowding are low. The results suggest that political culture and the efficiency of court functioning are each independently associated with conviction rates for DWI and may also be associated in a reciprocal fashion with both low DWI arrest rates and alcohol-involved crash rates.

Impairment related to blood amphetamine and/or methamphetamine concentrations in suspected drugged drivers.
Gustavsen I; Morland J; Bramness JG. Accident Analysis and Prevention 38(3): 490-495, 2006. (56 refs.)
Experimental studies have investigated effects of low oral doses of amphetamine and methamphetamine on psychomotor functions, while less work has been done on effects of high doses taken by abusers in real-life settings. There are indications that intake of high doses may impair traffic related skills, and that abuse of amphetamines may cause hypersomnolence at the end-of-binge. The present study aimed at investigating the concentration-effect relationship between blood amphetamines concentrations and impairment in a population of real-life users. Eight hundred and seventy-eight cases with amphetamine or methamphetamine as the only drugs present in the blood samples were selected from the impaired driver registry at The Norwegian Institute of Public Health. In each case the police physician had concluded on whether the driver was impaired or not. 27% of the drivers were judged as not impaired, while 73% were judged as impaired. There was a positive relationship between blood amphetamines concentrations and impairment. The relationship reached a ceiling at blood amphetamines concentrations of 0.27-0.53 mg/l. Younger drivers were more often judged impaired than older drivers at similar concentrations. Despite the performance enhancing qualities of amphetamines demonstrated in some low dose laboratory experiments; this study revealed a positive relationship between blood amphetamines concentration and traffic related impairment.

The efficacy of experimental interventions designed to reduce drinking among designated drivers.
Lange JE; Reed MB; Johnson MB; Voas RB. Journal of Studies on Alcohol 67(2): 261-268, 2006. (30 refs.)
Objective: Designated drivers are a popular strategy for avoiding drunk driving. However, studies have demonstrated that the strategy is often implemented poorly, resulting in diminished risk-reduction effectiveness. The purpose of this study was to test the efficacy of six interventions designed to reduce alcohol consumption among designated drivers. Method: A total of 376 groups consisting of 1,412 pedestrians (57.8% men) were recruited as they crossed into Tijuana, Mexico, from San Diego, CA. Before crossing into Mexico, each group was assigned at random to one of six experimental conditions or to one control condition. The six interventions were designed to (1) cue the use of designated drivers, (2) change attitudes about designated drivers, (3) provide monetary rewards for driver sobriety, and (4) increase group supportive norms for proper designated driver use. Participant breath alcohol concentrations (BrACs) were collected before entering Mexico and on return to the United States. Results: Using group members to deliver pro-designated driver messages significantly decreased driver and passenger BrACs relative to controls. Male drivers were more likely to return from Mexico with BrACs of zero if they were rewarded. Among female drivers, wearing a bracelet with the printed words "designated driver" in addition to cuing resulted in 9 of 10 drivers returning with BrACs equal to zero. Conclusions: These results demonstrate that designated driver sobriety can be enhanced through brief interventions, and proper use of the designated driver concept did not increase the risk of excessive alcohol consumption for passengers.

Understanding the effect of deployment on the risk of fatal motor vehicle crashes: A nested case-control study of fatalities in Gulf War era veterans, 1991-1995.
Hooper TI; DeBakey SF; Bellis KS; Kang HK; Cowan DN; Lincoln AE et al. Accident Analysis and Prevention 38(3): 518-525, 2006. (24 refs.)
Motor vehicle crashes (MVCs) are an important cause of morbidity and premature loss of life among military personnel during peacetime and particularly following combat. A nested case-control study of fatal MVC occurring between 1991 and 1995 was conducted in a cohort of Gulf War era veterans. Cases were validated MVC deaths in the Fatality Analysis Reporting System. Controls were selected using risk set sampling by gender and year of case ascertainment in a 10: 1 ratio. Preliminary results, consistent with previous reports of increased fatal MVC risk among returning combat veterans, showed a crude odds ratio of 1.45 (95% confidence interval 1.27-1.65). Multivariable logistic regression modeling was used to identify important independent predictors, as well as to quantify the influence of deployment on a risk profile for fatal MVC. Because of significant interaction between deployment and inpatient diagnosis of substance abuse, the final model was stratified by deployment status. Results suggest that demographic, military, and behavioral characteristics of deployed healthy warriors are similar to the risk profile for fatal MVC. In addition to young, single, high school-educated, enlisted male personnel, those who served during times of ground combat, particularly in infantry, gun crews, or seamanship occupations, should be targeted for preventive interventions.

The impact of a novel educational curriculum for first-time DUI offenders on intermediate outcomes relevant to DUI recidivism.
Rider R; Kelley-Baker T; Voas RB; Murphy B; McKnight AJ; Levings C. Accident Analysis and Prevention 38(3): 482-489, 2006. (21 refs.)
The Preventing Alcohol-Related Convictions (PARC) program is a novel educational curriculum for first-time DUI offenders, with the ultimate goal of reducing DUI recidivism. It differs from traditional DUI education and prevention programs in that it does not suggest to DUI offenders that they must abstain from alcohol entirely or control their drinking to prevent a future DUI; rather, it teaches students to prevent a future DUI by not driving their cars to drinking events. Thus, the emphasis of the curriculum is on controlling driving rather than controlling drinking to avoid future DUI convictions. The implementation of the program is ongoing throughout the state of Florida. The current randomized study focused on intermediate outcomes relevant for DUI recidivism; specifically, individuals' readiness for change regarding drinking and driving, and their endorsement of a PARC planning and action approach (controlling driving) versus a traditional approach (controlling drinking). The current research demonstrated that the PARC program is effective in moving participants toward more readiness for change and toward a strategy of planning ahead to avoid driving to any venue in which drinking may occur. Future research will assess the ultimate effect on DUI recidivism. Copyright 2006, Elsevier Science Ltd.
Predicting DUI recidivism: Personality, attitudinal, and behavioral risk factors.
Schell TL; Chan KS; Morral AR. Drug and Alcohol Dependence 82(1): 33-40, 2006. (53 refs.)
Aims: To predict DUI recidivism using personality, attitudinal, and behavioral factors. Design: We conducted cross-sectional analyses of survey data. Covariance structure modeling wag used to identify unique predictors of driving after drinking (DAD), alcohol consumption, and high-risk driving. Participants: Two hundred and eighty individuals with multiple DUI convictions, predominately male and Hispanic. Participants were surveyed in the Rio Hondo Courthouse, Los Angeles County, California. Measurements: The survey included measures of past year frequency of DAD, socially desirable response bias, sensation seeking, trait hostility, high-risk driving style, alcohol expectancies, and alcohol consumption. Findings: DAD was positively related with frequency of drinking and with positive alcohol expectancies. It was negatively associated with socially desirable response bias. Measures of high-risk driving and the personality variables were highly negatively associated with socially desirable response bias. Conclusions: Individuals who believe that they are affected positively by alcohol intoxication are not responding to the standard penalties for DUI and persist in driving after drinking. These beliefs may serve as an important point of intervention for programs designed to reduce drunk driving. The current research also suggests that self-report measures of DAD, as well as many hypothesized risk factors, are highly correlated with socially desirable response biases. Failure to control for such biases may be a significant threat to the validity of research in this field. Copyright 2006, Elsevier Science.
