A Large-scale Study of the Characteristics of Impaired Drivers in Treatment in Texas

Motorcycle riding under the influence of alcohol: results from the SARTRE-4 survey

Riding a motorcycle under the influence of alcohol is a dangerous activity, especially considering the high vulnerability of motorcyclists. The present research investigates the factors that affect the declared frequency of drink-riding among motorcyclists in Europe and explores regional differences. Data were collected from the SARTRE-4 (Social Attitudes to Road Traffic Risk in Europe) survey, which was conducted in 19 countries. A total sample of 4483 motorcyclists was interviewed by using a face-to-face questionnaire. The data were analyzed by means of multilevel ordered logit models. The results revealed significant regional differences (between Northern, Eastern and Southern European countries) in drink-riding frequencies in Europe. In general, declared drinking and riding were positively associated with gender (males), increased exposure, underestimation of risk, friends' behaviour, past accidents and alcohol ticket experience. On the other hand, it was negatively associated with underestimation of the amount of alcohol allowed before driving, and support for more severe penalties.

Rural and Urban Differences in Kentucky DUI Offenders

OBJECTIVES

: Recent national data suggest that the prevalence of driving under the influence (DUI) is higher in rural areas than in more urbanized areas of the United States. However, little is known about rural DUI offenders, particularly those living in very remote areas. This study was conducted to examine the similarities and differences between rural and urban DUI offenders. Based on recent research, it was expected that few differences would be found between rural and urban DUI offenders.

METHODS

: This study examined a total of 21,135 substance abuse assessment records for persons convicted of DUI in Kentucky and who concluded treatment in 2005. Assessment records included demographic characteristics, Alcohol Use Disorders Identification Test scores, Drug Abuse Screening Test scores, and the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition Text Revision substance use disorder checklist. Beale codes based on county of residence were used to create comparison groups.

RESULTS

: Positive, and statistically significant, associations were found between rurality and Drug Abuse Screening Test scores, Diagnostic and Statistical Manual of Mental Disorders Fourth Edition substance abuse and dependence disorders, and rates of education/treatment noncompliance. Alcohol Use Disorders Identification Test scores were negatively associated with rurality.

CONCLUSIONS

: The study suggests that the problem severity among DUI offenders may be greater in rural areas. Given the lack of treatment services in rural areas, practitioners may face greater challenges in assessing and providing appropriate treatment for this group of DUI offenders, which may put them at greater risk for continued impaired driving.

Unraveling the complexity of driving while intoxicated: a study into the prevalence of psychiatric and substance abuse comorbidity

OBJECTIVE

Research is beginning to provide an indication of the co-occurring substance abuse and mental health needs for the driving under the influence (DUI) population. This study aimed to examine the extent of such psychiatric problems among a large sample size of DUI offenders entering treatment in Texas.

METHODS

This is a study of 36,373 past year DUI clients and 308,714 non-past year DUI clients admitted to Texas treatment programs between 2005 and 2008. Data were obtained from the State's administrative dataset.

RESULTS

Analysis indicated that non-past year DUI clients were more likely to present with more severe illicit substance use problems, while past year DUI clients were more likely to have a primary problem with alcohol. Nevertheless, a cannabis use problem was also found to be significantly associated with DUI recidivism in the last year. In regards to mental health status, a major finding was that depression was the most common psychiatric condition reported by DUI clients, including those with more than one DUI offence in the past year. This cohort also reported elevated levels of Bipolar Disorder compared to the general population, and such a diagnosis was also associated with an increased likelihood of not completing treatment. Additionally, female clients were more likely to be diagnosed with mental health problems than males, as well as more likely to be placed on medications at admission and more likely to have problems with methamphetamine, cocaine, and opiates.

CONCLUSIONS

DUI offenders are at an increased risk of experiencing comorbid psychiatric disorders, and thus, corresponding treatment programs need to cater for a range of mental health concerns that are likely to affect recidivism rates.
