AbstractDistress caused by sensory processing differences for autistic individuals may be reduced by repetitive behaviours (RRB), including repetitive motor (RMB) and insistence on sameness (ISB) behaviours. Intolerance of uncertainty (IU) and anxiety mediate the relationship between sensory processing and RRB in autistic children. We replicated this model in autistic adults, extending it to include alexithymia. Serial mediation, using data from 426 autistic adults, identified significant direct effects from sensory processing to RMB and ISB, and indirect effects through alexithymia-IU-anxiety for RMB, and IU alone, and alexithymia-IU for ISB. Different mechanisms may underpin RMB and ISB. Alexithymia alongside, IU and anxiety, should be considered when understanding the relationship between sensory processing and RRB, and when offering interventions to support autistic people.

Anxiety is present in high rates in both children and adults on the autism spectrum. An increasing number of studies have highlighted the potentially important role that intolerance of uncertainty may have in anxiety for those on the spectrum, as well as their interrelationships with sensory sensitivities and repetitive behaviours. In response to a lack of studies involving adults, this study examined self-report survey data regarding intolerance of uncertainty, sensory sensitivities, repetitive behaviours and anxiety in a sample of 176 adults on the autism spectrum (mean age = 42). Intolerance of uncertainty and anxiety were both found to be elevated relative to non-autistic adults ( N = 116) and significant, positive correlations were found between intolerance of uncertainty, anxiety, repetitive behaviours and sensory sensitivities in those on the spectrum. Intolerance of uncertainty was found to be a significant mediator between sensory sensitivities and anxiety, as well as between anxiety and insistence on sameness behaviours. These results were not sensitive to age. Intolerance of uncertainty is an important factor to be considered in the conceptualisation and management of elevated rates of anxiety for adults on the autism spectrum.

Background: People with an Autism Spectrum Condition diagnosis (ASD) are hypothesized to show atypical neural dynamics, reflecting differences in neural structure and function. However, previous results regarding neural dynamics in autistic individuals have not converged on a single pattern of differences. It is possible that the differences are cognitive-set-specific, and we therefore measured EEG in autistic individuals and matched controls during three different cognitive states: resting, visual perception, and cognitive control.Methods: Young adults with and without an ASD (N=17 in each group) matched on age (range 20 to 30 years), sex, and estimated Intelligence Quotient (IQ) were recruited. We measured their behavior and their EEG during rest, a task requiring low-level visual perception of gratings of varying spatial frequency, and the “Simon task” to elicit activity in the executive control network. We computed EEG power and Inter-Site Phase Clustering (ISPC; a measure of connectivity) in various frequency bands.Results: During rest, there were no ASD vs. controls differences in EEG power, suggesting typical oscillation power at baseline. During visual processing, without pre-baseline normalization, we found decreased broadband EEG power in ASD vs. controls, but this was not the case during the cognitive control task. Furthermore, the behavioral results of the cognitive control task suggest that autistic adults were better able to ignore irrelevant stimuli.Conclusions: Together, our results defy a simple explanation of overall differences between ASD and controls, and instead suggest a more nuanced pattern of altered neural dynamics that depend on which neural networks are engaged.

The Relationship

Camouflaging is a frequently reported behaviour in autistic people, which entails the use of strategies to compensate for and mask autistic traits in social situations. Camouflaging is associated with poor mental health in autistic people. This study examined the manifestation of camouflaging in a non-autistic sample, examining the relationship between autistic traits, camouflaging, and mental health. In addition, the role of executive functions as a mechanism underpinning camouflaging was explored. Sixty-three non-autistic adults completed standardised self-report questionnaires which measured: autistic traits, mental health symptoms, and camouflaging behaviours. In addition, a subset (n=51) completed three tests of executive function measuring inhibition, working memory, and set-shifting. Multiple linear regression models were used to analyse data. Results indicated that autistic traits are not associated with mental health symptoms when controlling for camouflaging, and camouflaging predicted increased mental health symptoms. Camouflaging did not correlate with any measure of executive function. These findings have implications for understanding the relationship between autistic traits and mental health in non-autistic people and add to the growing development of theory and knowledge about the mechanism and effects of camouflaging.

Cross-sectional research has demonstrated the overrepresentation of gender dysphoria in children and adults with autism spectrum disorder. However, the predictors and underlying mechanisms of this co-occurrence remain unclear. This follow-up study aimed to explore baseline (childhood/adolescence) predictors for the follow-up (adulthood) self-reported wish to be of the opposite sex and to investigate its mental health correlates in a sample of 88 autistic individuals as compared with 42 typically developing controls. An item on the Adult Self-Report Inventory-4, “I wish I was the opposite sex,” was used. We compared mental health symptoms between adults with and without this item endorsement. We used prediction models to explore family and autism-related predictors in childhood/adolescence to endorse this item in adulthood. There were more adults endorsing the item in the autism spectrum disorder group compared with the typically developing group. Autistic adults who endorsed the item experienced more mental health challenges, more bullying victimization, more suicidal ideations, and worse quality of life. Lower parent-reported family support and more stereotyped/repetitive behaviors during childhood/adolescence predicted the self-reported wish to be of the opposite sex in adulthood in autistic individuals. It is necessary to raise more attention to gender development and related mental health impact in autistic individuals. Lay abstract Autistic people/people with autism spectrum disorder are more likely to experience gender dysphoria. However, the possible longitudinal predictors and underlying mechanisms of this co-occurrence are unclear. To fill this knowledge gap, we assessed 88 people with autism spectrum disorder and 42 typically developing individuals at their average ages of 13.0 (baseline, childhood/adolescence) and 20.2 years old (follow-up, adulthood). At follow-up, their endorsement on the item “I wish I was the opposite sex” was used to evaluate gender dysphoric symptoms. We compared mental health symptoms between adults with and without this item endorsement at the follow-up assessment. We explored parent-reported family and autism characteristics-related predictors in childhood/adolescence to this item endorsement in adulthood. We found that more autistic adults reported the wish to be of the opposite sex than did typically developing individuals. Autistic adults who endorsed this item experienced more mental health challenges, more school bullying and cyberbullying, more suicidal ideation, and worse quality of life. Moreover, parent-reported lower family support and more stereotyped/repetitive behaviors during childhood/adolescence predicted the self-reported wish to be of the opposite sex in adulthood in autistic individuals. More attention and support should be provided to autistic people regarding gender development and related mental health and quality of life impact, especially during the transition period to young adulthood.

This study explored demographic and psychological predictors of alcohol use and misuse in a high-functioning, community sample of 237 autistic adults aged 18–75 (mean = 41.92 and standard deviation = 13.3) recruited in the United Kingdom. An online survey measured demographic information, autistic traits, depression, generalised anxiety, social anxiety, mental well-being, social camouflaging and alcohol use with the Alcohol Use Disorders Identification Test. The sample was divided into three groups (non-drinkers, non-hazardous drinkers and hazardous drinkers) and multinomial logistic regression models were used to investigate associations between alcohol use and demographic factors, autistic traits, mental health variables and social camouflaging. Our results demonstrated a U-shaped pattern among autistic adults, with non-drinkers and hazardous drinkers scoring significantly higher than non-hazardous drinkers on levels of autistic traits, depression, generalised anxiety and social anxiety. In multivariate analysis, autistic non-drinkers were less likely to be male (odds ratio = 0.44; 95% confidence interval = 0.22–0.87) and had more autistic traits (odds ratio = 2.50; 95% confidence interval = 1.19–5.28). Gender and level of autistic traits may be the most significant factors in predicting alcohol use in the autistic community. Lay abstract Alcohol use and misuse are associated with a variety of negative physical, psychological and social consequences. The limited existing research on substance use including alcohol use in autistic adults has yielded mixed findings, with some studies concluding that autism reduces the likelihood of substance use and others suggesting that autism may increase an individual’s risk for substance misuse. This study investigated demographic and psychological predictors of alcohol use and misuse in a sample of 237 autistic adults. An online survey was used to obtain data on demographic information, autistic traits, depression, generalised anxiety, social anxiety, mental well-being, social camouflaging and alcohol use. The sample was divided into three groups (non-drinkers, non-hazardous drinkers and hazardous drinkers) in order to investigate associations between alcohol use and demographic factors, autistic traits, mental health variables and social camouflaging. Our results demonstrated a U-shaped pattern among autistic adults, with non-drinkers and hazardous drinkers scoring higher than non-hazardous drinkers on levels of autistic traits, depression, generalised anxiety and social anxiety. Autistic non-drinkers were less likely to be male and had more autistic traits. Gender and level of autistic traits may be the most significant factors in predicting alcohol use in the autistic community.
