Researchers have found significant differences in self reported driving behaviours and perceptions of driving ability in autistic in comparison to non-autistic adults in a new study.
As the population of adults with autism continues growing rapidly, the survey provides a first step toward identifying whether this population has unmet needs for educational supports to empower safe driving - a key element of independent functioning in many people's lives.
AdvertisementStudy co-author Maria Schultheis, PhD, an associate professor of psychology at Drexel, said previous research in my lab has included extensive research in driving capacity with people who have a variety of conditions such as multiple sclerosis or who had experienced traumatic brain injury.
She said, "When investigated whether and under what circumstances a condition or neurological difference might affect driving ability, as a standard starting point we want to go to individuals and find out from their perspective what problems they are having on the road, in their real-world experience. That question is pivotal to shape and inform the goals of long-term research - and is especially important when we turn to look at a developmental difference like autism, where there has been too little research to establish yet whether widespread driving difficulties exist."
In this survey, adults with autism spectrum disorders reported earning their drivers' licenses at a later age, driving less frequently and putting more restrictions on their own driving behaviors (such as avoiding driving on highways or at night), on average compared to non-autistic adults. The respondents with autism spectrum disorders also reported more traffic violations.
Because this pilot study was relatively small and based on self-reports of 78 ASD respondents and 94 non-ASD comparison participants, Schultheis and study's lead author Brian Daly, PhD, an assistant professor of psychology in Drexel's College of Arts and Sciences, noted that the differences they found were open to several possible interpretations. Autistic adults may have reported driving less often and restricting their behaviors out of self-awareness of actual difficulties or deficiencies in their driving. These difficulties and/or reduced driving exposure could also explain the higher rate of reported violations.
The new study has been published online in the Journal of Autism and Developmental Disorders.
