Ready for a Learner's Permit? Clinical Neuropsychological Off-road Tests and Driving Behaviors in a Simulator among Adolescents with ADHD and ASD

Cardiac indices of driver fatigue across in-lab and on-road studies

Driver fatigue is a major contributor to road accidents. Therefore, driver assistance systems (DAS) that would monitor drivers' states may contribute to road safety. Such monitoring can potentially be achieved with input from ECG indices (e.g., heart rate). We reviewed the empirical literature on responses of cardiac measures to driver fatigue and on detecting fatigue with cardiac indices and classification algorithms. We used meta-analytical methods to explore the pooled effect sizes of different cardiac indices of fatigue, their heterogeneity, and the consistency of their responses across studies. Our large pool of studies (N = 39) allowed us to stratify the results across on-road and simulator studies. We found that despite the large heterogeneity of the effect sizes between the studies, many indices had significant pooled effect sizes across the studies, and more frequently across the on-road studies. We also found that most indices showed consistent responses across both on-road and simulator studies. Regarding the detection accuracy, we found that even on-road classification could have been as accurate as 70% with only 2-min of data. However, we could only find two on-road studies that employed fatigue classification algorithms. Overall, our findings are encouraging with respect to the prospect of using cardiac measures for detecting driver fatigue. Yet, to fully explore this possibility, there is a need for additional on-road studies that would employ a similar set of cardiac indices and detection algorithms, a unified definition of fatigue, and additional levels of fatigue than the two fatigue vs alert states.

Effectiveness of a Driving and Community Mobility Intervention for Teens and Young Adults With Autism Spectrum Disorder

IMPORTANCE

Driving and community mobility (DCM) is key to supporting independence in teens and young adults (TYA) with autism spectrum disorder (ASD).

OBJECTIVE

To determine whether an intervention focused on DCM can effectively improve DCM knowledge and skills in TYA.

DESIGN

A pretest-posttest design using the same intervention and outcome measures.

SETTING

University research setting.

PARTICIPANTS

Thirty-eight participants with ASD completed the program (M age = 17.76 yr, SD = 3.58). Twenty-six (68%) were male, and 12 (32%) were female.

INTERVENTION

A 5-day intensive intervention using group and individualized strategies, including driving simulation, focused on improving performance skills needed for DCM.

OUTCOME AND MEASURES

Total and category scores of the Performance Analysis of Driving Ability (P-Drive) were analyzed using a repeated-measures analysis of variance measuring time (pretest vs. posttest), gender, and year of intervention. Paired t tests were used to determine the outcomes of the Canadian Occupational Performance Measure (COPM), anxiety measure and perception survey.

RESULTS

Results indicated a significant main effect for time (p < .001) and year (p < .036), but not gender (p < .26), with no significant interaction effects, supporting the fidelity of the intervention. The COPM showed significant changes (p ≤ .001) in both performance and satisfaction, as well as a reduction in anxiety (p = .008).

CONCLUSIONS AND RELEVANCE

Outcomes suggest that the intervention successfully improved DCM knowledge and skills for TYA. This adds new evidence that an occupational therapy intervention specific to TYA with ASD is effective in developing independence in DCM. Plain-Language Summary: Driving is the primary mode of community mobility in North America and other Western countries. Adults with autism spectrum disorder (ASD) who have a means of community mobility have a chance of employment that is 5 times greater than that for those who do not. Driving and community mobility are key to supporting independence among teens and young adults with ASD. However, teens and young adults with ASD have significantly lower rates of getting a driver's license. The results of this study show that occupational therapy practitioners can play a critical role in addressing driving and community mobility. Occupational therapy interventions that are specifically designed for and unique to each teen and young adult with ASD can effectively improve driving and community mobility skills and increase independence.

A comprehensive review of attention tests: can we assess what we exactly do not understand?

Attention, as it is now defined as a process matching data from the environment to the needs of the organism, is one of the main aspects of human cognitive processes. There are several aspects to attention including tonic alertness (a process of intrinsic arousal that varies by minutes to hours), phasic alertness (a process that causes a quick change in attention as a result of a brief stimulus), selective attention (a process differentiating multiple stimuli), and sustained attention (a process maintaining persistence of response and continuous effort over an extended period). Attention dysfunction is associated with multiple disorders; therefore, there has been much effort in assessing attention and its domains, resulting in a battery of tests evaluating one or several attentional domains; instances of which are the Stroop color-word test, Test of Everyday Attention, Wisconsin Card Sorting Test, and Cambridge Neuropsychological Test Automated Battery. These tests vary in terms of utilities, range of age, and domains. The role of attention in human life and the importance of assessing it merits an inclusive review of the efforts made to assess attention and the resulting tests; Here we highlight all the necessary data regarding neurophysiological tests which assess human attentive function and investigates the evolution of attention tests over time. Also, the ways of assessing the attention in untestable patients who have difficulty in reading or using a computer, along with the lack of ability to comprehend verbal instructions and executive tasks, are discussed. This review can be of help as a platform for designing new studies to researchers who are interested in working on attention and conditions causing deficits in this aspect of body function, by collecting and organizing information on its assessment.

Virtual reality in the diagnostic and therapy for mental disorders: A systematic review

BACKGROUND

Virtual reality (VR) technologies are playing an increasingly important role in the diagnostics and treatment of mental disorders.

OBJECTIVE

To systematically review the current evidence regarding the use of VR in the diagnostics and treatment of mental disorders.

DATA SOURCE

Systematic literature searches via PubMed (last literature update: 9^th of May 2022) were conducted for the following areas of psychopathology: Specific phobias, panic disorder and agoraphobia, social anxiety disorder, generalized anxiety disorder, posttraumatic stress disorder (PTSD), obsessive-compulsive disorder, eating disorders, dementia disorders, attention-deficit/hyperactivity disorder, depression, autism spectrum disorder, schizophrenia spectrum disorders, and addiction disorders.

ELIGIBILITY CRITERIA

To be eligible, studies had to be published in English, to be peer-reviewed, to report original research data, to be VR-related, and to deal with one of the above-mentioned areas of psychopathology.

STUDY EVALUATION

For each study included, various study characteristics (including interventions and conditions, comparators, major outcomes and study designs) were retrieved and a risk of bias score was calculated based on predefined study quality criteria.

RESULTS

Across all areas of psychopathology, k = 9315 studies were inspected, of which k = 721 studies met the eligibility criteria. From these studies, 43.97% were considered assessment-related, 55.48% therapy-related, and 0.55% were mixed. The highest research activity was found for VR exposure therapy in anxiety disorders, PTSD and addiction disorders, where the most convincing evidence was found, as well as for cognitive trainings in dementia and social skill trainings in autism spectrum disorder.

CONCLUSION

While VR exposure therapy will likely find its way successively into regular patient care, there are also many other promising approaches, but most are not yet mature enough for clinical application.

The effect of attention-deficit/hyperactivity disorder (ADHD) on driving behavior and risk perception

OBJECTIVE

To examine the effect of attention-deficit/hyperactivity disorder (ADHD) on differences in driving behavior and risk perception, in experienced drivers.

METHODS

A total of 147 experienced drivers participated in the study. Drivers with ADHD (n = 91) were compared to an age-matched control group of drivers (n = 56) with no neuropsychiatric diagnoses. A simulator driving test (SDT) was used in the study and included a driving scenario with various traffic environments to examine any differences in number of collisions, number of speedings, risk index (based on 12 risky situations), speed adaptation (based on 19 road sections), mean speed, and preferred speed, between the two groups. The participants also completed a questionnaire about their driving behavior.

RESULTS

No differences in the simulator driving test were found between the ADHD group and the control group. No adverse effects of ADHD were found for any of the measures, i.e., collisions, number of speeding, risk index, speed adaptation, mean speed and preferred speed. The only significant group difference was that drivers with ADHD rated themselves lower on concentration.

CONCLUSIONS

Participants with ADHD and the control group drove remarkably similarly in the simulator driving test and rated themselves similarly regarding how they drive. The results contribute to state that ADHD drivers are less deviant than asserted by previous research.
