Study Notes

Driver Behavior Questionnaire and Driver Style Inventory

Participants were asked to rate their driving behaviors, thoughts, and feelings on a 6-point scale, encompassing reckless and careless, anxious, angry and hostile, and patient and careful driving styles.
The Multidimensional Driving Style Inventory explores the social psychology of road safety and driver personality through scales, inventories, and self-report instruments.
Driving stress is a response to the perception of driving as demanding or dangerous, leading to subjective responses like anxiety and anger, and performance outcomes such as impaired psychomotor control.
Driver stress is influenced by environmental stressors, personality factors, and the effectiveness of coping strategies, impacting hazard monitoring and dislike of driving.
The Driver Stress Inventory (DSI) measures five dimensions of stress vulnerability: driving aggression, dislike of driving, hazard monitoring, thrill-seeking, and fatigue proneness.
The DSI uses an 11-point Likert scale to gauge agreement with each item, ranging from "not at all" to "very much," providing insights into stress susceptibility.
References include studies on the association between anger and aggressive driving, interventions for reducing driving anger, and the development of driving anger scales and measures.
Driver stress and driving performance are explored in the International Encyclopedia of Transportation, with a focus on the impact of stress on driving capabilities.
Self-report instruments and methods are examined in the Handbook of Traffic Psychology, offering insights into driving behavior and skills, and the validation of the Driver Stress Inventory in China.
The relationship between dangerous driving behaviors and the Driver Stress Inventory is explored, shedding light on the impact of stress on driving behavior.
The International Encyclopedia of Transportation delves into aggressive driving and road rage, providing a comprehensive understanding of driver aggression and anger.
Driver aggression and anger are further explored in the International Encyclopedia of Transportation, focusing on the measure for angry drivers (MAD) and the impact of anger on driving behavior.

Publication Bias, Study Quality, and Drug-Related Road Accidents

Factors like age and gender are commonly controlled for in studies, but only a minority of studies control for annual driving distance.
The absence of control for driving distance in most studies on the risk of accidents related to drug use introduces uncertainty in the results.
Study quality is a concept that lacks a standard definition but is widely acknowledged to influence the reliability of findings.
Publication bias, where studies with non-significant or unexpected results are less likely to be published, can distort the overall evidence.
Funnel plots, used in meta-analysis, can visually detect potential publication bias by showing asymmetry in the distribution of study results.
An example of publication bias is the overestimation of the true effect size in a meta-analysis or systematic review.
Experimental evidence has shown that both cannabis and alcohol are associated with increases in speed and lateral position variability while driving.
Studies on drug-related road accidents often lack precise information about the dose of drugs taken, leading to uncertainty in the findings.
The causality of the relationship between drug use and road accidents has not been definitively established.
A meta-analysis on prescription opioids included studies with an appropriate comparison group and quantitative data on the association.
The risk of road accidents associated with drug use is more likely to be increased by drug use, but causality has not been fully established.
Many studies lack precise information about the dose of drugs taken, which adds to the uncertainty in understanding the relationship between drug use and road accidents.

Experimental Evidence on Alcohol-Impaired Driving

A systematic review and meta-analysis of 17 original publications involving 962 participants examined the impact of acute alcohol consumption on simulated driving performance.
Measures included the standard deviation of lane position (SDLP) and standard deviation of speed (SDSP) during 50 repeated-measures trials.
Acute alcohol consumption (BAC range: 23–100 mg·dL−1) significantly increased SDLP by 4.0 ± 0.5 cm and SDSP by 0.38 ± 0.10 km·h−1.
Correlation between change in BAC level and change in SDLP was observed.
The study also analyzed the effect of acute alcohol intake on the number of lane crossings (LC) within a BAC range of 62-78 mg·dL−1.
The impact of alcohol and marijuana on the central nervous system, relative risk of accidents, epidemiological studies, and meta-analyses on alcohol effects were examined.
Challenges in establishing the relationship between drug use and accident risk were discussed, including difficulties in determining drug dose and impairment, controlling for other factors, summarizing the relationship, testing and adjusting for publication bias, and assessing study quality.
Case-control and culpability studies were highlighted as research designs used to investigate the relationship between drug use and accident involvement.
Challenges in collecting high-quality data on drug use were identified, especially in roadside surveys, due to the invasive nature of blood sampling and reliance on less reliable sources of data such as saliva and urine samples or self-reported use.
The complexity of estimating the contribution to risk attributable to drug use was emphasized, as it depends on a host of factors, making it challenging to control for all known factors influencing accident risk.
The text also raised questions about the relationship between cannabis and road accidents, as well as the challenges in studying the effect of prescription drugs on driving.
The difficulty in estimating the relationship between drug use and accident risk, particularly in controlling for other influencing factors, was highlighted as a significant challenge in research.
