Reassessing Fitness-to-Drive in Drinker Drivers: The Role of Cognition and Personality

The Association Between Internal Restlessness, Drinking Motives, and Alcohol Use Outcomes in College Students

BACKGROUND

ADHD and alcohol use are prevalent among college students, but few studies have examined internal restlessness (i.e., the mental discomfort experienced when suppressing hyperactive behaviors) in relation to alcohol use. Consequently, the current study sought to examine a path model testing associations between internal restlessness, drinking motives (i.e., coping, social, enhancement, and conformity), alcohol use, and consequences in college students.

METHODS

Two hundred and ninety-one college students completed an online survey regarding their use of alcohol.

RESULTS

After controlling for ADHD diagnosis, there were significant positive associations between internal restlessness and coping (B = 0.025, p = .004), socializing (B = 0.026, p = .004), enhancement (B = 0.038, p < .001), and conformity (B = 0.026, p < .001). Two significant indirect effects were found for the association between internal restlessness and consequences through enhancement (95% CI [0.001, 0.009]) and coping (95% CI [0.000, 0.011]) motives and alcohol use, respectively. All other indirect pathways were nonsignificant.

CONCLUSIONS

Findings revealed that internal restlessness was associated with the four drinking motives; however, greater internal restlessness was related to more alcohol consequences to the extent that they also reported strong coping and enhancement motives. Findings can be used to tailor intervention and prevention efforts to target emotional regulation and to reduce risk for college students who experience internal restlessness.

Effect of Fitness-To-Drive and Metacognition on Road Traffic Injury Among Older Taxi Drivers: Hierarchical Modeling

Age-related cognitive and somatic motor skills changes have been linked to impaired driving abilities. Taxi drivers play an important role in providing public transportation services and security. This study aimed to examine the level of fitness-to-drive (FTD) and identify the predictors of self-reported traffic injury among the older taxi drivers. Taxi drivers 60 years and older in Bangkok and the metropolitan area were enrolled. Hierarchical regression models were carried out to examine the effects of demographics, FTD, and metacognition towards self-reported road traffic injury. Totally, 46.1% of the respondents were classified as at-risk drivers. Drivers with alcohol consumption and low risk perception toward road safety were more likely to experience road traffic injury. Regular assessment of physical and psychometric capacity among older taxi drivers could provide another empirical basis to improve public safety transport.
