The relationship between stress and social functioning in adults with autism spectrum disorder and without intellectual disability

How to build resiliency in autistic individuals: an implication to advance mental health

INTRODUCTION

Individuals on the autism spectrum (ASD) often experience poor mental health and coping strategies compared to their peers due to social exclusion and co-occurring conditions. Resiliency has been identified as a key factor in preventing adverse outcomes and promoting mental health. Therefore, it is important to determine what strategies can be used to build resiliency among autistic individuals. The current paper is one of the first studies that aims to collect information from autistic individuals and their caregivers on potential strategies to enhance resiliency.

METHODS

We interviewed 18 participants from various provinces in Canada, comprising of 13 autistic individuals and 5 parents. We used thematic analysis to identify patterns in the data.

RESULTS

Thematic analysis revealed three themes to indicate strategies that could be used to enhance resiliency, including: (a) self-reliant strategies, (b) using community-based facilities, and (c) contextual and individual characteristics.

CONCLUSION

Although the body of literature on resiliency is evolving, this paper provides a unique perspective as it is one of the few studies that considers the experiences of individuals on the spectrum. In addition, this study focuses on identifying and describing specific strategies that can be used to enhance resiliency and mental health, which consequently can help address the existing gaps in knowledge and practice.

Trajectories of positive affect in autistic individuals during the transition to adulthood

LAY ABSTRACT

Recent research has revealed informative patterns about health, mental health, self-help skills, autism symptoms, and social skills during the transition to adulthood for autistic individuals. This study expands on these findings by examining how positive affect (e.g. excited) changes from age 15 to 30 years using a group of individuals first referred for autism at an early age. We also examined the agreement between caregiver-report and self-report on positive affect. We found different patterns of stability and change in positive affect across the transition to adulthood that related to differences in autism severity, cognitive abilities, self-help skills, as well as social and work participation in adulthood. The agreement between caregiver-report and self-report was strong in adolescence but became much weaker after the individuals were 23 years. These results have implications for how we measure happiness, positive emotions, or other internal experiences of autistic individuals.

Cognitive emotion regulation difficulties increase affective reactivity to daily-life stress in autistic adolescents and young adults

LAY ABSTRACT

Previous research has shown that autistic individuals report high levels of perceived stress and have an increased likelihood of developing mental health difficulties. Increase in individuals' negative emotions in relation to perceived stress (i.e. affective reactivity to stress) is a known risk factor for mental health difficulties. In this study, we investigated perceived daily stress and affective reactivity to stress in autistic (n = 39, age = 18.4) and non-autistic (n = 55, age = 18.1) adolescents and young adults. We used the ecological momentary assessment, a technique that allows to assess individuals repeatedly in their daily life using their smartphone. Moreover, participants filled a questionnaire to evaluate the strategies they use to regulate emotions when faced with difficulties. Finally, a clinical interview and a parent-report questionnaire were used to assess mental health symptoms. Autistic youth reported higher levels of perceived daily stress compared with non-autistic peers. Moreover, they showed increased affective reactivity to stress related to their daily activities. Autistic participants reported more emotion regulation difficulties (e.g. more repetitive thinking of difficulties) compared with non-autistic participants. Difficulties in emotion regulation increased negative emotions in relation to stress and might contribute to the severity of mental health symptoms. We conclude that adolescents and young adults with autism report high perceived stress in their daily lives. To minimize the negative impact of stress and the development of mental health symptoms, people supporting autistic young people could focus on stress management skills and the strategies that the youth use to manage emotions.

What is the Meaning of Paid Employment for Well-Being? A Focus Group Study on Differences and Similarities Between Autistic Adults With and Without Employment

PURPOSE

The aim of the present study was to explore the meaning of work for the subjective well-being of autistic adults with and without paid (competitive) employment and to evaluate the differences and similarities between these groups.

METHODS

Eight focus groups were conducted, including a total of 64 autistic adults. Four groups entailed participants with current paid employment (including part-time) and four groups entailed participants without paid employment. All discussions were audiotaped and transcribed verbatim to enable inductive thematic content analysis. Data were analyzed using ATLAS.ti 9.

RESULTS

Generally, both groups viewed paid employment as very important for well-being, albeit for different reasons. Three themes were found: (1) Not having paid employment was associated with lacking societal recognition, and subsequent low self-esteem, which was a dominant theme in those without work; (2) Work can seriously damage (mental) health and well-being, found in both groups; and (3) Paid employment provides many benefits for well-being, with subthemes: 'purpose,' 'social contacts,' 'growth and use of talents,' 'structure and calmness,' and 'income and freedom', which was a dominant theme in those with paid employment.

CONCLUSIONS

Both groups found paid employment highly important for their well-being, albeit for different reasons. However, both also agreed that paid employment can be very harmful to (mental) health and well-being. Suitable, well-supported jobs are important for well-being, may help to buffer stress in other life areas, and may even prevent autistic burnout. More studies are needed on how healthy jobs can be created where autistic individuals get positive energy and experience high well-being. This will also help to reduce socio-economic inequality.

Stress in autism (STREAM): A study protocol on the role of circadian activity, sleep quality and sensory reactivity

Mental health issues are markedly increased in individuals with autism, making it the number one research priority by stakeholders. There is a crucial need to use personalized approaches to understand the underpinnings of mental illness in autism and consequently, to address individual needs. Based on the risk factors identified in typical mental research, we propose the following themes central to mental health issues in autism: sleep difficulties and stress. Indeed, the prevalence of manifold circadian disruptions and sleep difficulties in autism, alongside stress related to sensory overload, forms an integral part of autistic symptomatology. This proof-of-concept study protocol outlines an innovative, individualised approach towards investigating the interrelationships between stress indices, sleep and circadian activation patterns, and sensory sensitivity in autism. Embracing an individualized methodology, we aim to collect 14 days of data per participant from 20 individuals with autism diagnoses and 20 without. Participants' sleep will be monitored using wearable EEG headbands and a sleep diary. Diurnal tracking of heart rate and electrodermal activity through wearables will serve as proxies of stress. Those objective data will be synchronized with subjective experience traces collected throughout the day using the Temporal Experience Tracing (TET) method. TET facilitates the quantification of relevant aspects of individual experience states, such as stress or sensory sensitivities, by providing a continuous multidimensional description of subjective experiences. Capturing the dynamics of subjective experiences phase-locked to neural and physiological proxies both between and within individuals, this approach has the potential to contribute to our understanding of critical issues in autism, including sleep problems, sensory reactivity and stress. The planned strives to provide a pathway towards developing a more nuanced and individualized approach to addressing mental health in autism.

Female mice prenatally exposed to valproic acid exhibit complex and prolonged social behavior deficits

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized mainly by deficits in social communication and stereotyped and restricted behavior and interests with a male to female bias of 4.2/1. Social behavior in ASD animal models is commonly analyzed in males, and seldomly in females, using the widely implemented three-chambers test procedure. Here, we implemented a novel procedure, the Live Mouse Tracker (LMT), combining artificial intelligence, machine learning procedures and behavioral measures. We used it on mice that were prenatally exposed to valproic acid (VPA) (450 mg/kg) at embryonic day 12.5, a widely recognized and potent ASD model that we had previously extensively characterized. We focused on female mice offspring, in which social deficits have been rarely documented when using the 3-CT procedure. We recorded several parameters related to social behavior in these mice, continuously for three days in groups of four female mice. Comparisons were made on groups of 4 female mice with the same treatment (4 saline or 4 VPA) or with different treatments (3 saline and 1 VPA). We report that VPA females show several types of social deficits, which are different in nature and magnitude in relation with time. When VPA mice were placed in the LMT alongside saline mice, their social deficits showed significant improvement as early as 1 h from the start of the experiment, lasting up to 3 days throughout the duration of the experiment. Our findings suggest that ASD may be underdiagnosed in females. They also imply that ASD-related social deficits can be ameliorated by the presence of typical individuals.

The relationship between autistic traits and the stress of social isolation: Development of an explanatory model

Background

Social isolation can be particularly challenging for individuals with high autistic traits who struggle with social interactions. The COVID-19 pandemic led to increased isolation, exacerbating stress for those who may have difficulty in connecting with others. This study aimed to explore the relationship between autistic traits and stress associated with social isolation.

Methods

A sample of 1597 Chinese adults completed measures of autistic traits, the stress of social isolation, psychological inflexibility and core self-evaluation, during an epidemic prevention and control period of COVID-19 in Chongqing, China. Measures included the Autism-Spectrum Quotient, Coronavirus Stress Measure, Acceptance and Action Questionnaire-II, and Core Self-Evaluation Scale.

Results

Autistic traits were positively correlated with the stress of social isolation, which was mediated by the chain effect of core self-evaluation and psychological inflexibility. individuals with high autistic traits reported significantly higher stress than individuals with low autistic traits.

Limitations

This was a cross-sectional study, which limits causal inference. In addition, data were self-reported, which may cause methodological effects. Finally, this study was conducted during China's quarantine policy and external validation of the findings is required.

Conclusions

Autistic traits are positively associated with the stress of social isolation. Autistic traits affected core self-evaluation first, and psychological inflexibility subsequently, leading to the stress of social isolation. individuals with high autistic traits tended to experience higher levels of stress during pandemic quarantines. The findings provide useful evidence for developing interventions and implementing preventive measures to reduce stress in individuals with high autistic traits and autism spectrum disorder.

Psychosocial therapeutic approaches for high-functioning autistic adults

Autism spectrum disorder (ASD) is characterized by impaired social interaction and communication skills, repetitive behaviors, restricted interests, and specific sensory processing. Particularly, adults with high-functioning ASD often remain unrecognized, presumably due to their high compensatory skills, but at the cost of high stress, which is often linked to anxiety and depression. This may further explain the significantly high suicide rates and reduced life expectancy among individuals with ASD. Thus, providing support to high-functioning autistic adults in managing core symptoms, as well as co-occurring anxiety and depression, appears essential. To date, only a limited number of evidence-based psychosocial therapeutic options are available, and very few of them have undergone rigorous evaluation in a clinical context. To obtain a comprehensive understanding, a systematic literature search was conducted according to the PRISMA checklist, and only studies demonstrating robust methodological quality were included and discussed in this review article. Although promising initial key factors and methods have been identified, additional evidence-based studies are imperative to ascertain the optimal treatment and evaluate the long-term outcomes for adults with high-functioning ASD.

Stress and well-being in autistic adults: Exploring the moderating role of coping

The wider stress literature points to negative associations between stress and well-being. Similarly, the use of engagement coping strategies and disengagement coping strategies in the face of stress are related to improved and reduced well-being respectively. However, in the autistic population stress and coping research is limited to date, and the extent to which coping may moderate the relationship between stress and well-being is not known. Using data from an Australian online study, we explored the potential moderating (i.e. buffering or exacerbating) role of coping in the relationship between stress and well-being in a sample of autistic adults (N = 86). Our findings indicated that increased stress was associated with lower well-being. Further, moderation analyses showed that while both engagement coping (e.g. problem solving, positive appraisal) and disengagement coping (e.g., self-distraction, being in denial) strategies had significant positive and negative direct effects on well-being respectively; engagement coping also moderated the relationship between stress and well-being, buffering the impact of stress on well-being. Our results illustrate the different underlying mechanisms by which coping strategies may be associated with stress and well-being. They also highlight the potential protective role of engagement coping strategies, which can be incorporated into the promotion and maintenance of well-being in autistic adults.

Psychological, behavioural and biological factors associated with gastrointestinal symptoms in autistic adults and adults with autistic traits

LAY ABSTRACT

Little is known about factors related to the increased risk for gastrointestinal symptoms in adults with an autism spectrum disorder (ASD), while the negative impact of gastrointestinal symptoms is evident. Especially, the relationship between gastrointestinal symptoms and psychological, behavioural, and biological risk factors in adults with ASD (traits) is unclear. Autistic peer support workers and autism-advocates also emphasised the importance of identifying risk factors, because of the high prevalence of gastrointestinal problems in people with ASD. Therefore, our study investigated which psychological, behavioural, and biological factors are associated with gastrointestinal symptoms in adults with ASD or with autistic traits. We analysed data from 31,185 adults in the Dutch Lifelines Study. Questionnaires were used to evaluate the presence of an autism spectrum disorder diagnosis, autistic traits, gastrointestinal symptoms, psychological and behavioural factors. Biological factors were examined with body measurements. We found that not only adults with ASD but also adults with higher levels of autistic traits were at increased risk for gastrointestinal symptoms. Adults with ASD who experienced psychological problems (psychiatric problems, worse perceived health, chronic stress) had a higher risk for gastrointestinal symptoms than adults with ASD without these psychological problems. Moreover, adults with higher levels of autistic traits were less physically active, which was also associated with gastrointestinal symptoms. In conclusion, our study highlights the relevance of identifying psychological problems and evaluating physical activity when trying to help adults with ASD or autistic traits and gastrointestinal symptoms. This suggests that healthcare professionals should be more aware of behavioural and psychological risk factors when evaluating gastrointestinal symptoms in adults with ASD (traits).

Measuring the prevalence of autistic traits in a cohort of adults living with HIV or taking HIV pre-exposure prophylaxis and mapping safer-sex barriers and facilitators: a study protocol

INTRODUCTION

Autistic individuals identify with a wider range of sexual orientations than non-autistic individuals, including higher rates of bisexual orientation in autistic men. Gay, bisexual and other men who have sex with men are at greater risk for HIV. Prevalence data of autistic traits in people living with HIV or using Pre-Exposure Prophylaxis (PrEP) for HIV are lacking so far. Such data, combined with insights in barriers and facilitators for safer sex in autistic people living with HIV or using PrEP, are a first step to improve health support for autistic people in HIV clinics. This support is crucial since autistic individuals have worse physical and mental health outcomes. The objective of this research is to determine the prevalence of autistic traits within the group of people living with HIV or using PrEP in Belgium and to describe specific facilitators and barriers for sexual safer behaviour in people living with HIV and PrEP users with autistic traits.

METHODS AND ANALYSIS

The research is a cross-sectional, observational and multicentre study with recruitment of individual participants. The research consists of two phases. In phase 1, adults coming for HIV/AIDS care or HIV PrEP in participating Belgian HIV Reference Centres will be invited to fill in the validated Autism Spectrum Quotient questionnaire. In phase 2, participants with a score above the predefined cut-off for autistic traits (>26), who agreed to be informed about this score, will be invited to complete an additional survey, inquiring facilitators and barriers for sexual safer behaviour.

Salivary Oxytocin and Antioxidative Response to Robotic Touch in Adults with Autism Spectrum Disorder

Individuals with ASD are known to have a tendency to have tactile sensory processing issues that could be associated with their impairment as regards social communication. The alterations in tactile processing in autistic subjects are usually accompanied by hypersensitivity and other unpleasant emotions induced by tactile contact. In our study, we investigated the impact of the velocity and the force of a tactile stroke received impersonally by a custom-built robotic device. A total of 21 adults with ASD and 22 adults from a control group participated in our study. The participants' responses were assessed according to subjective scales, EEG changes, and the dynamics of saliva antioxidants and oxytocin. It was found that the oxytocin level was significantly lower in subjects with ASD but increased after tactile stimulation. However, contrary to expectations, the increase in the oxytocin level in the target group negatively correlated with the subjective pleasantness of tactile stimulation and was probably associated with a stress-induced effect. The basic levels of antioxidants did not differ between the TD and ASD groups; however, these had significantly increased in individuals with ASD by the end of the study. The EEG findings, which revealed enhanced antioxidant levels, contributed to the relief of the cognitive control during the study.

Brief Report: Longitudinal Role of Coping Strategies on Mental Health Outcomes in Autistic Youth and Adults

The stress literature suggests that coping strategies are implicated in mental health outcomes. However, the longitudinal relationship between coping strategies and mental health in the autistic adult population has not yet been examined. This 2-year longitudinal study examined the predictive role of both baseline and change in coping strategy use over time (i.e., an increase or decrease) on anxiety, depression, and well-being after 2-years in 87 autistic adults aged 16 to 80 years. Controlling for baseline mental health, both baseline and increase in disengagement coping strategies (e.g., denial, self-blame) predicted higher anxiety and depression, and lower well-being, while an increase in engagement coping strategies (e.g., problem solving, acceptance) predicted higher well-being. These findings extend the current coping literature in autistic adults, offering insight into mental health support and intervention options.

Resilience and Coping Strategies in Adults with Autism Spectrum Disorder

Individuals with Autism spectrum disorder (ASD) are prone to stress and anxiety affecting their mental health. Although developing coping and resilience are key to cope with stressors of life, limited research exists. We aimed to explore stakeholders' experiences related to the coping and resilience of adults with ASD. We interviewed 22 participants, including 13 adults with ASD, five parents, and four service provides of adults with ASD from various Canadian provinces. Using thematic analysis, three themes emerged including: (a) societal expectations and conformity, (b) adjusting daily routines, and (c) learning overtime. This study highlights the importance of coping and informs the development of services to help enhance resilience among adults with ASD.

Eye Movement Desensitization and Reprocessing in adolescents with autism; Efficacy on ASD symptoms and stress

INTRODUCTION

Eye Movement Desensitization and Reprocessing (EMDR) is a well-established and thoroughly researched treatment method for posttraumatic stress symptoms. When patients with an autism spectrum disorder (ASD) are treated with EMDR for their Posttraumatic Stress Disorder (PTSD), they sometimes report a decrease in the core symptoms of ASD. This explorative pre-post-follow up design study is designed to investigate whether EMDR with a focus on daily experienced stress, is effective in reducing ASD symptoms and stress in adolescents with ASD.

METHODS

Twenty-one adolescents with ASD (age 12 to 19) were treated with ten sessions EMDR, focusing on events of daily experienced stress.

RESULTS

No significant decrease of ASD symptoms was found on the total score of the Social Responsiveness Scale (SRS) as reported by caregivers from baseline to end measurement. However, there was a significant decrease on total caregivers SRS score comparing the baseline to the follow-up measurement. On two subscales, Social Awareness and Social Communication, a significant decrease was found from baseline to follow-up. On the subscales Social Motivation and Restricted Interests and Repetitive Behavior, no significant effects were found. On pre- and posttest scores of total ASD symptoms measured by the Autism Diagnostic Observation Schedule (ADOS-2), no significant effects were found. On the contrary, scores on self-reported Perceived Stress Scale (PSS) showed a significant decrease from baseline to follow-up. Also, 52% of adolescents showed a significant improvement of global clinical functioning at endpoint measurement on the Clinical Global Impression Improvement, rated by an independent child psychiatrist.

DISCUSSION

In sum, these results of this uncontrolled study suggest a partial effect of EMDR in adolescents with ASD on ASD symptoms, rated by their caregivers. In addition, the results of this study show that EMDR treatment on daily experienced stress significantly reduce perceived stress as reported by the participants, and improves global clinical functioning. The results also suggest a 'sleeper effect', since no significant effects were found between baseline- and post- treatment measurements, but only between baseline- and follow up three months after the treatment. This finding is in line with other studies investigating psychotherapeutic effects in ASD. Implications for clinical practice and suggestions for future research are discussed.

Depressive symptoms in workers with high autistic trait scores according to job stress type

Individuals with high levels of autistic traits are at a high risk of experiencing depressive symptoms, and are also vulnerable to job stress. This study aimed to identify which combination of autistic traits and type of job stress are related to depressive symptoms. Participants comprised 992 workers from different regions of Japan. Autistic traits, depressive symptoms, and job stress were measured using the Autism-Spectrum Quotient, K6 scale, and Job Content Questionnaire, respectively. Logistic regression was performed to estimate the odds ratio and 95% confidence interval. Workers with high autistic traits scores reported significantly more depressive symptoms for all job stress types, especially high job demand. Depressive symptoms differed according to autistic traits and job stress. In workers with high autistic trait subscale scores, those with active job stress reported more depressive symptoms than those with high strain job stress, except for the "poor imagination" trait. This is contrary to previous reports that the active stress type is generally less associated with depressive symptoms than the high-strain stress type. To prevent depressive symptoms in workers with high autistic trait scores, it is important to understand which combination of autistic traits and type of job stress contribute to depressive symptoms.

Coping-resilience profiles and experiences of stress in autistic adults

Emerging studies allude to high stress in autistic adults. Considering the detrimental impact of stress on health outcomes, examining individual resources which may influence the extent to which stress is experienced (e.g., coping and resilience) is vital. Using a person-focused approach, this study aimed to identify coping-resilience profiles, and examine their relations to general perceived stress and daily hassles in a sample of autistic adults (N = 86; aged 19-74 years). Cluster analysis identified four coping-resilience profiles (i.e., high cope/ low resilience, low cope/ high resilience, engage cope/ high resilience, and disengage cope/ low resilience). The high cope/ low resilience and disengage cope/ low resilience groups had significantly higher general perceived stress than the remaining groups. No significant group differences were noted in relation to daily hassles. Jointly addressing coping and resilience may be beneficial on the perceived stress experienced in autistic adults. The use of coping-resilience profiles may also allow for the personalization of stress management and support options in the autistic adult population.

Performance- and Theater-Based Interventions for Supporting Social Cognition and Social Communication in Autistic Youth: A Review and Theoretical Synthesis

Social skills interventions (SSIs) are commonly used to improve social functioning in youth with autism spectrum disorder (ASD), which is a condition characterized by differences in social cognition and social communication. Although more traditional SSIs have used knowledge-based, didactic instruction, recent research has explored the utility of performance-based SSIs, which use various activities to support implicit learning of social skills in supportive, enriched environments. This article reviews the extant literature evaluating the effectiveness or efficacy of five performance-based SSIs using theater-based approaches on social cognition and social communication. Overall, this body of literature suggests social communication gains that include increased peer interactions, peer liking, and reciprocal friendships, as well as social cognitive gains in theory of mind and affect recognition. This review also discusses theoretical models that may help explain the emerging strengths of performance- and theater-based SSIs with underlying hypotheses related to the social communication and social cognitive differences in ASD. Limitations of performance-based SSIs in the evidence-base include several approaches in initial stages of research with small sample sizes and limited maintenance of effects. Future research should aim to bridge the research-to-practice gap and use more rigorous designs and more diverse samples, including those with cooccurring intellectual disability.

Virtual Group-Based Mindfulness Intervention for Autistic Adults: a Feasibility Study

Objectives

Although mindfulness-based interventions have been shown to be helpful in reducing psychological distress in autistic adults, limited research has explored virtual delivery in the autism community. We designed an adapted virtual group-based mindfulness intervention, based on input from autistic adults, and evaluated its feasibility in terms of demand, acceptability, implementation, practicality, adaptation, and limited efficacy testing.

Methods

Informed by an online needs assessment survey of 77 autistic adults, 37 individuals completed a six-week autism informed manualized course delivered virtually. Participants completed pre, post, and 12-week follow up, and also provided qualitative feedback.

Results

There was a demand for the course, adaptations were successful, and participants indicated good acceptability of the intervention. Open-ended feedback highlighted advantages and challenges with the technology, the benefits of connecting with other autistic adults, and unique aspects of the mindfulness instruction. Participants reported reduced levels of distress which were maintained at three-month follow-up, and increased mindfulness, and self-compassion.

Conclusions

Autism-informed adaptations to standard mindfulness-based interventions can lead to self-reported improvements in mindfulness, self-compassion, and distress by autistic adults. Continued research with outcome measures tailored toward autistic adults will be important, during and post-pandemic.

Associations between coping strategies and mental health outcomes in autistic adults

Compared to the general population, mental health difficulties are commonly reported in autistic adults. However, the ways in which coping strategies are associated with mental health and well-being in this population remain unknown. Further, we do not know if, and if so, how these associations might differ to that of non-autistic adults. In this study, we hypothesized that in both our autistic (N = 255) and non-autistic (N = 165) adult samples, disengagement coping strategies (e.g., denial) would relate to poorer mental health and well-being, while engagement coping strategies (e.g., problem solving) would relate to better mental health and well-being. Regression analyses revealed that higher use of disengagement coping strategies was significantly associated with higher levels of anxiety and depression, and lower levels of well-being in both samples. In contrast, increased use of engagement coping strategies was associated with better well-being, but only in the autistic sample. Our results contribute to the characterization of negative and positive mental health outcomes in autistic adults from a coping perspective, with potential to offer novel information regarding coping strategies to consider when addressing support options for mental health difficulties in the autistic adult population.

OUP accepted manuscript

Mesenchymal stem cell-based therapy has emerged as a great potential approach to treat individuals with autism spectrum disorders (ASD), a group of developmental disabilities characterized by impairments in social interaction and communication. Stem cells from human exfoliated deciduous teeth (SHED), holding earlier developing characteristics, have immune-modulatory and anti-inflammatory properties. To investigate whether SHED transplantation can rescue autistic-like symptoms in SHANK3 mutant beagle dogs, 12 SHANK3 mutant beagle dogs were randomly assigned into 2 groups according to their behavior evaluated by social interaction tests. Six mutant dogs received 6 intravenous infusions of SHED and were followed up for 3 months by testing social interaction and inflammatory cytokine levels. We found that infusion of SHED significantly improved impaired social novel preference of SHANK3 mutant beagle dogs at 1- and 3-month follow-ups. Social intimacies (following, sniffing, and licking) between mutant beagle dogs and human experimenters were partly improved. Stressed tail posture, indicating social stress, was also significantly alleviated. In addition, we showed that the levels of serum interferon-γ and interleukin-10 were notably increased and decreased, respectively, in SHANK3 mutant beagle dogs. Infusion of SHED was able to rescue altered interferon-γ and interleukin-10 levels. We failed to observe any serious adverse events after infusion of SHED. In summary, SHED transplantation may be a safe and effective therapy for ASD. The correction in the levels of serum interferon-γ and interleukin-10 may serve as an index to predict autistic severity and therapeutic outcomes.

Impact of Working Together for adults with autism spectrum disorder: a multifamily group intervention

BACKGROUND

Adults with autism spectrum disorder (ASD) have lower engagement in their communities, higher rates of unemployment/underemployment, and continued difficulties with challenging behavior compared to their neurotypical peers. Multi-family psychoeducation emphasizes education and problem-solving with the goal of improving these outcomes for the individual with the disability.

METHODS

Using a randomized waitlist control design, the present study evaluated a multi-family group psychoeducation intervention, Working Together, for adults on the autism spectrum without intellectual disability (n = 40). Five waves of data were collected at 3-month intervals. In this design, families in the intervention condition participated in intervention during the 6 months between baseline and time 3 data collection; the waitlist control condition received the intervention immediately after the time 3 data collection. We compared these two conditions, intervention group (n = 20) vs waitlist control group (n = 20), on key outcomes for the adults with ASD: engagement in work-related activities, engagement in meaningful activities, and behavior problems.

RESULTS

Results indicated medium to large effect sizes associated with the Working Together intervention across key outcomes, including adults on the spectrum experiencing significant increases in meaningful activities and decreases in internalizing problems. Although increases in work-related activities were not statistically significant, an observed one-half of a standard deviation difference from before to after the intervention indicated clinically significant change. We also found maintenance of the treatment effect through 6 months post-treatment for the intervention group and replication of the treatment effect within the control group after they received the intervention.

CONCLUSION

Working Together is a promising multi-family group psychoeducation intervention designed to improve functioning during adulthood. These findings highlight the need for more intervention services research during adulthood and specifically the need for family-centered supports.

A Systematic Review of Self-Reported Stress Questionnaires in People on the Autism Spectrum

Background

The goal of this systematic review was to provide an overview of self-report measures of stress in populations on the autism spectrum. In addition, information regarding psychometric properties was discussed as well.

Methods

Four databases were systematically searched following the PRISMA guidelines and using strict eligibility criteria. Risk of bias assessment was performed using the COSMIN checklist.

Results

Eight questionnaires were previously used in populations on the autism spectrum, reported over 31 studies.

Discussion

Future research should focus more on examining psychometric properties of these self-report measures in this population as current evidence is scarce. In addition, it is important to consider which concept of stress one aims to measure as not all questionnaires cover the same aspects of stress.

The effects of Animal Assisted Therapy on autonomic and endocrine activity in adults with autism spectrum disorder: A randomized controlled trial

OBJECTIVE

Stress and its sequelae are very common in adults with autism spectrum disorder (ASD) without an intellectual disability (ID). Animal-assisted therapy (AAT) has shown physiological stress-reductive effects in children with ASD. The aim of the current study was to examine the acute psychophysiological response to an AAT session, and to examine the longer-term stress-physiological effects of the intervention, up until 10 weeks post-treatment, in comparison to waiting-list controls.

METHOD

A randomized controlled trial with pre-intervention (T0), post-intervention (T1: 10 weeks) and follow-up (T2: 20 weeks) measurements of neuroendocrine and cardiovascular measures, was conducted in 53 adults with ASD (N = 27 in intervention arm; N = 26 in control arm). Within the intervention group, stress-physiological data were collected during the 5th therapy session (acute effects). Data were analyzed with mixed models for outcome measures cortisol, alpha-amylase, heart rate variability and sympathetic activity.

RESULTS

The AAT interventional session was significantly associated with reduced cortisol levels (β = -0.41, p = .010), while parasympathetic and sympathetic cardiovascular activity remained unaltered. No significant changes were found for stress-physiological measures at post-treatment time points.

CONCLUSIONS

Acute stress reduction, reflected in significant reduction in cortisol levels, was found during an AAT session in adults with ASD, without ID. More research is needed to explore to what extent the specific factors of AAT have contributed to the decrease in cortisol and whether stress reduction is possible for the longer-term.

Autistic traits and gender modulate emotion changes before and during the COVID-19 pandemic

Individuals with autism spectrum disorder (ASD) show an enhanced response to stressors, and gender plays an important role in stress response. Thus, autistic traits (ATs) in the general population and gender may regulate the emotion changes before and during the COVID-19 pandemic. In the present study, participants were divided into higher and lower ATs groups. The generalized linear models were used to estimate the effects of the independent variables (e.g. the COVID-19 pandemic status (before, during), gender (male, female), and AT groups (higher ATs, lower ATs) and their interactions on emotions measured by the Positive and Negative Affect scales. The results showed that the COVID-19 pandemic reduced positive emotions and increased fear and anger. Furthermore, compared with the status before the COVID-19 pandemic, individuals with higher ATs and females experienced stronger anger and fear than individuals with lower ATs and males during the pandemic. The present study revealed the emotional impacts of the COVID-19 pandemic and greater emotional susceptibility to the pandemic among individuals with higher ATs and females. Our findings provide prospective evidence for understanding the ASD/ATs-related enhanced response to pathogen threat-related stressors and have implications for COVID-19 crisis interventions.

Lifetime and perceived stress, social support, loneliness, and health in autistic adults

OBJECTIVES

Although the health consequences of life stress exposure in the general population are well known, how different stressors occurring over the lifetime cause morbidity and mortality in autism is unclear, as are the factors that moderate and mediate these associations. The few studies that have compared autistic and nonautistic individuals have used instruments that yield few stress exposure indices and assess stressors occurring over short time periods.

METHOD

To address these issues, we used the Stress and Adversity Inventory to assess lifetime stressor exposure and perceived stressor severity in 127 autistic and 104 nonautistic adults. Moderated mediation analysis examined associations between stressor exposure and physical and mental ill-health with respect to the hypothesized mediating role of stressor perception, and moderation effects of loneliness and social support.

RESULTS

Autistic adults experienced more lifetime stressors and generally perceived stressors as being more severe. Greater perceived stressor severity was related to poorer physical and mental health and to greater loneliness and lower social support for both groups. An additional post hoc analysis of the association between diagnostic status and mental ill-health revealed that loneliness mediated the relation between being autistic and having poorer mental health.

CONCLUSION

Autistic individuals experienced more lifetime stressors, and their impact on physical and mental health was mediated by perceived stressor severity. Moreover, loneliness and low social support were associated with greater negative impact of lifetime stress exposure on mental health. Interventions that reduce cognitive-perceptual stress appraisals, and that target loneliness and social support, may help reduce risk for stress-related disease in autistic individuals.

Engrailed 2 deficiency and chronic stress alter avoidance and motivation behaviors

Autism spectrum disorder (ASD) is a pervasive neurodevelopmental disorder characterized by impairments in social interaction, cognition, and communication, as well as the presence of repetitive or stereotyped behaviors and interests. ASD is most often studied as a neurodevelopmental disease, but it is a lifelong disorder. Adults with ASD experience more stressful life events and greater perceived stress, and frequently have comorbid mood disorders such as anxiety and depression. It remains unclear whether adult exposure to chronic stress can exacerbate the behavioral and neurodevelopmental phenotypes associated with ASD. To address this issue, we first investigated whether adult male and female Engrailed-2 deficient (En2-KO, En2-/-) mice, which display behavioral disturbances in avoidance tasks and dysregulated monoaminergic neurotransmitter levels, also display impairments in instrumental behaviors associated with motivation, such as the progressive ratio task. We then exposed adult En2-KO mice to chronic environmental stress (CSDS, chronic social defeat stress), to determine if stress exacerbated the behavioral and neuroanatomical effects of En2 deletion. En2-/- mice showed impaired instrumental acquisition and significantly lower breakpoints in a progressive ratio test, demonstrating En2 deficiency decreases motivation to exert effort for reward. Furthermore, adult CSDS exposure increased avoidance behaviors in En2-KO mice. Interestingly, adult CSDS exposure also exacerbated the deleterious effects of En2 deficiency on forebrain-projecting monoaminergic fibers. Our findings thus suggest that adult exposure to stress may exacerbate behavioral and neuroanatomical phenotypes associated with developmental effects of genetic En2 deficiency.

"It's like a ramp for a person in a wheelchair": Workplace accessibility for employees with autism

BACKGROUND, AIMS AND METHODS

Participation in employment by individuals with autism spectrum disorders (ASD) remains restricted despite their high motivation and evident abilities. Challenges to employment result from personal characteristics and environmental barriers. This phenomenological research explores the accessibility of a competitive work environment according to the perceptions of adults with ASD.

PROCEDURES AND OUTCOMES

We conducted in-depth interviews with 19 employees with ASD, followed by a thematic content analysis. Three themes emerged: (a) the employees' motivation for employment, (b) challenges and abilities at work, and (c) workplace accessibility (types of accommodations, implementation process).

RESULTS AND CONCLUSIONS

The findings contribute a classification of accommodations that addresses the core characteristics of autism-challenges as well as abilities and motivations for employment. Four types of accommodations were identified: job-performance communication, attitudes and interpersonal communication, daily workplace routines, and physical and sensory environments. Hence, this study supports the centrality of environmental factors in successful employment of individuals with ASD.

IMPLICATIONS

This study presents an evidence-based foundation for autism-related workplace accessibility. It offers an approach to enhance employees' abilities, strengths, and motivation for employment, as well as to decrease barriers and challenges. The findings may expand organizational policies regarding accessibility and thereby anchor workplace accommodations within organizations' corporate cultures.

Inter-relationships between trait resilience, coping strategies, and mental health outcomes in autistic adults

Resilience has been depicted as a key characteristic in the promotion of mental health in the face of stress and adversity. Despite high levels of stress encountered in the autistic population, resilience studies remain scarce. Using data from an Australian longitudinal adult study, this study explored the inter-relationships between trait resilience, coping, and mental health in a sample of autistic adults (N = 78). In particular, we examined the relationship between resilience and use of coping strategies, and the potential mediating role of coping strategies in the relationship between resilience and mental health outcomes. Our findings suggested that increased use of engagement coping (e.g., problem-solving, positive appraisal) and decreased use of disengagement coping (e.g., self-blame, being in denial) strategies were associated with higher levels of resilience. Further, mediation analysis results suggest that disengagement coping mediated the associations between resilience and all three mental health outcomes (i.e., depression, anxiety, and well-being), while engagement coping strategies mediated the relationship between resilience and well-being only. Our results illustrate that coping strategies may be an important mechanism in explaining the resilience-mental health relationship in autistic adults, highlighting the importance of considering stress-related constructs together (i.e., trait resilience and coping) when addressing support and intervention options for mental health difficulties in the autistic adult population. LAY SUMMARY: This research explored how resilience and coping strategies influence the mental health and well-being of autistic adults. We found that resilient autistic adults used more engagement coping strategies, less disengagement coping strategies, and reported better mental health and well-being. Considering stress-related factors together (i.e., resilience and coping) offers a novel perspective to mental health difficulties in autistic adults and may be a vital step in the development of support options in this population.

Inclusive Communication Model Supporting the Employment Cycle of Individuals with Autism Spectrum Disorders

Difficulties with interpersonal communication experienced by individuals with autism spectrum disorders (ASD) significantly contribute to their underrepresentation in the workforce as well as problems experienced while in employment. Consistently, it is vital to understand how communication within the employment cycle of this group can be improved. This study aims to identify and analyze the possibilities of modifying the communication processes around recruitment, selection, onboarding, and job retention to address the specific characteristics and needs of the representatives of this group. This qualitative study is based on 15 in-depth interviews conducted with 21 field experts, i.e.,: therapists, job trainers, and entrepreneurs employing people with ASD. The findings of this research informed the creation of an inclusive communication model supporting the employment cycle of individuals with ASD. The most important recommendations within the model that was created include the modification of job advertisements, use of less structured job interviews, providing opportunities for mentorship, and supportive and non-direct, electronically mediated communication. To apply the above-mentioned solutions and take full advantage of the talents of people with ASD, it is also necessary to provide tailored sensitivity and awareness training programs for their direct addressees as well as their neurotypical colleagues, including managerial staff.

The bullies are the leaders of the next generation: Inherited aminergic neurotransmitter system changes in socially dominant zebrafish, Danio rerio

We studied the social hierarchy in zebrafish and assessed differences in neurotransmitters and behavior in the F1 generation offspring of dominant and subordinate zebrafish (Danio rerio). We used behavioral assays to study locomotion, ability to complete cognitive tasks, social interaction and aggression. To study the neurochemical changes, we applied quantitative polymerase chain reaction, high pressure liquid chromatography and immunohistochemistry. Social hierarchies were formed both by males and females when animals were kept in same sex pairs in the dyadic dominant-subordinate hierarchy test. The offspring of dominant animals were the leaders in social interactions, however aggression in the mirror-test was not altered in any group. Serotonin and noradrenaline levels were lower in the F1 generation subordinate animals when compared with dominant animals, but not compared with animals that were naïve to social hierarchy. The mRNA level of the rate-limiting enzyme in histamine synthesis, histidine decarboxylase, was significantly lower in dominant and subordinate larval zebrafish when compared with control animals. In the dominant adult zebrafish tyrosine hydroxylase 1 mRNA level was lower compared with control animals, whereas tyrosine hydroxylase 2 mRNA was not different. The result was verified with immunohistochemistry. There were gender specific differences between the dominant and subordinate animals, where the dominant females performed better in cognitive tasks such as the T-maze than subordinate females. This was not observed in males, as the behavior of the dominant and subordinate males did not differ. These results add to the understanding of the plastic nature of the central nervous system and show that neurochemical features in aminergic neurotransmitter systems are associated with social leadership and dominance.

Heightened risk of posttraumatic stress disorder in adults with autism spectrum disorder: The role of cumulative trauma and memory deficits

BACKGROUND

Individuals with Autism Spectrum Disorder (ASD) are known to be at increased risk of exposure to traumas such as maltreatment and abuse, however less is known about possible susceptibility towards the development of Posttraumatic Stress Disorder (PTSD) and associated risk factors.

AIMS

This study investigated the rates of trauma exposure and PTSD, and the role of cumulative trauma exposure and memory as risk factors for PTSD in adults who self-reported having received an ASD diagnosis, compared to a typically developing (TD) comparison group.

METHODS

Questionnaires assessing self-reported frequency of trauma exposure (LEC), PTSD symptomology (PCL-S) and memory (EMQ- R and BRIEF-A) were completed online by 38 ASD adults and 44 TD adults.

RESULTS

Rates of trauma exposure and PTSD symptomatology were significantly higher in the ASD group, compared to the TD group, with deficits in working memory and everyday memory mediating this association. Interestingly, a cumulative effect of trauma exposure on PTSD symptom severity was only found in the ASD group.

CONCLUSIONS

High rates of trauma and probable PTSD in ASD adults highlight the importance of routine screening. Cumulative trauma exposure and memory deficits may act to increase risk of PTSD in ASD; longitudinal research is called for.

Brief Report: Mindfulness Training for Chinese Adolescents with Autism Spectrum Disorder and Their Parents in Hong Kong

This study investigated the feasibility and preliminary effectiveness of a concurrent mindfulness program (MYmind) on Chinese adolescents with autism spectrum disorder and their parents in Hong Kong, China using a randomized controlled trial with a waitlist control group. Results showed the study had 80% compliance rate, 0% dropout rate, and 89% response rate. Between-group comparisons showed mindfulness had trend effects on parent’s rumination (g = 1.16), mindful parenting (d = 0.6), parenting style (d = 0.59), and parenting stress (d = 0.5). The study demonstrated the feasibility of the MYmind program in the Chinese context. A larger trial with longer follow-up period is suggested to better examine the effect of mindfulness on adolescents with ASD and their parents.

Evidence for decreased parasympathetic response to a novel peer interaction in older children with autism spectrum disorder: a case-control study

Background

Individuals with autism spectrum disorder (ASD) often experience elevated stress during social interactions and may have difficulty forming and maintaining peer relationships. The autonomic nervous system (ANS) directs physiological changes in the body in response to a number of environmental stimuli, including social encounters. Evidence suggests the flexibility of the ANS response is an important driving factor in shaping social behavior. For youth with ASD, increased stress response and/or atypical ANS regulation to benign social encounters may therefore influence social behaviors, and, along with developmental and experiential factors, shape psychological outcomes.

Methods

The current study measured ANS response to a peer-based social interaction paradigm in 50 typically developing (TD) children and 50 children with ASD (ages 10–13). Respiratory sinus arrhythmia (RSA), a cardiac measure of parasympathetic influence on the heart, and pre-ejection period (PEP), a sympathetic indicator, were collected. Participants engaged in a friendly, face-to-face conversation with a novel, same-aged peer, and physiological data were collected continuously before and during the interaction. Participants also reported on state anxiety following the interaction, while parents reported on the child’s social functioning and number of social difficulties.

Results

Linear mixed models revealed that, while there were no diagnostic effects for RSA or PEP, older youth with ASD appeared to demonstrate a blunted parasympathetic (RSA) response. Further, increased severity of parent-reported social symptoms was associated with lower RSA. Youth with ASD reported more anxiety following the interaction; however, symptoms were not related to RSA or PEP response based on linear mixed modeling.

Conclusions

Physiological regulation, age, and social functioning likely influence stress responses to peer interactions for youth with ASD. Parasympathetic functioning, as opposed to sympathetic arousal, may be especially important in behavioral regulation, as older youth with ASD demonstrated atypical regulation and response to the social interaction paradigm. Future studies should help to further elucidate the developmental factors contributing to stress responses in ASD, the impact of physiological response on observable social behavior, and potential long-term consequences of chronic social stress in youth with ASD.

Correlates of daily functioning in older adults with autism spectrum disorder

Objectives: Studies of adults with autism spectrum disorder (ASD) have demonstrated poor outcomes related to independence and everyday living skills compared to the general population. In a sample of 74 adults with ASD who require a high level of support we sought to identify correlates of daily functioning.Methods: We administered questionnaires to residential staff and identified participants' independence level in basic and instrumental activities of daily living.Results: There was no association of age with daily functioning. Higher daily functioning was associated with a better general medical health rating. Functional independence was greater in participants with IQ range of 55 to 65 compared to those with IQ below 55. Language difficulties and behavioral disturbances were not significantly correlated with independence in daily living skills. In this sample, individual had held a median of three different types of jobs in supported employment.Conclusion: Daily functioning in adults with autism generally does not decline with age, but because this was cross-sectional data, this requires further confirmation. Community programs designed for adults with ASD who require a high level of support should focus on overall medical health and promotion of daily living skill building.

Associations of childhood experiences with event-related potentials in adults with autism spectrum disorder

Childhood maltreatment is defined as experiencing of physical, emotional and sexual abuse and neglect in childhood. Maltreatment in childhood leads to substantial psychosocial problems later in life in the general population. Individuals with autism spectrum disorder (ASD) have a higher risk of experiencing stressful and traumatic events, such as maltreatment, during childhood. Although childhood maltreatment reportedly leads to psychosocial problems in adults with ASD, the biological associations between childhood experiences and brain function in this population remain understudied. Here, we evaluated the relationships between childhood experiences and event-related potential (ERP) components during the auditory odd-ball task in adults with ASD (N = 21) and typically developed (TD) individuals (N = 22). We found that the higher the severity of sexual abuse, the larger the amplitude of P300 at Fz, Cz, C3, and C4 in individuals with ASD. Conversely, the severity of child maltreatment was associated with P300 latency at Cz and C3 in TD individuals. Moreover, full IQ was significantly associated with the MMN amplitude at Fz, Cz, C3, and C4 in TD individuals. These findings provide the first evidence that ERPs could be used to study the impacts childhood experiences on the brain of individuals with ASD and that childhood sexual abuse has salient impacts on brain function in this population.

A Comparison of the Stress Survey Schedule in Children with Autism and Typically Developing Children: A Brief Report

Past research suggests that stress and anxiety are more prevalent in persons with autism as compared to typically developing persons. The Stress Survey Schedule (SSS) was developed in 2001 as a means to measure stressors common to persons with Autism Spectrum Disorder (ASD). The present study compared SSS responses of a sample of students diagnosed with ASD and intellectual disability with a group of typically developing students to explore the divergent validity and internal consistency of this measure, and to assess changes in scores among pre-adolescent and adolescent populations. Results indicated significant mean differences in SSS scores between persons with ASD and persons who are typically developing, and mean score differences among identified ASD age groups.

Autism: Implications for high secure psychiatric care and move towards best practice

BACKGROUND/AIMS

To explore the role of high secure psychiatric care (HSPC) in the assessment and management of individuals with an Autism Spectrum Disorder (ASD) using published studies and clinical experience. Key areas of exploration include the prevalence of ASD within HSPC, some autism specific issues including clinical and cognitive characteristics, psychopathy and emotional regulation, presence of incompatibilities and use of seclusion, as well as experiences of being detained in HSPC. Developing best practice and a specialist ASD service in HSPC is also discussed.

METHOD

A discussion of available literature, supported by clinical experience.

CONCLUSIONS

Although individuals with an ASD admitted to HSPC comprise a small group, they are likely to be overrepresented relative to the general prevalence of ASD in the population and present with specific issues. Whilst individuals report a generally positive experience of HSPC, therapeutic outcomes are variable and the factors influencing them poorly understood. Staff knowledge and application of ASD theory and practice appears to have a significant influence on outcomes.

IMPLICATIONS

Although best practice concerning ASD secure services will continue to be improved and developed, the role of HSPC in the assessment and management of some individuals with an ASD who present with complex needs and high risk behaviours remains clear.

Long-term outcome of autism spectrum disorder

In most cases, autism spectrum disorder is a life-long condition, often severely affecting the quality of life of the patient and his/her family, but nowadays this diagnosis should not be considered a final sentence without appeal. Although even today the recovery from the autism spectrum is an unlikely possibility, a timely psycho-educational intervention can significantly improve the level of autonomy reached by the individual and therefore favorably modify the outcome. Some predictors of long-term outcome are known, primarily childhood intelligence quotient and early language/communication ability, but today this issue is still open. The lack of studies evaluating the long-term effects of the most important intervention programmes should be filled with adequate research. Community support and social integration may be very important in improving outcomes for individuals with autism spectrum disorder. But a real social integration involves a work activity and this is still a great problem today. An adequate and timely preparation of the working career of these individuals is fundamental for their future, and it should be done by choosing, as far as possible, suitable activities for them. Finally, in creating a dignified future for people with autism, we must never forget to listen to their point of view, whenever possible, in order to meet their particular needs.

Stress-Induced Neuron Remodeling Reveals Differential Interplay Between Neurexin and Environmental Factors in Caenorhabditis elegans

Neurexins are neuronal adhesion molecules important for synapse maturation, function, and plasticity. Neurexins have been genetically associated with neurodevelopmental disorders, including autism spectrum disorders (ASDs) and schizophrenia, but can have variable penetrance and phenotypic severity. Heritability studies indicate that a significant percentage of risk for ASD and schizophrenia includes environmental factors, highlighting a poorly understood interplay between genetic and environmental factors. The singular Caenorhabditis elegans ortholog of human neurexins, nrx-1, controls experience-dependent morphologic remodeling of a GABAergic neuron in adult males. Here, I show remodeling of this neuron's morphology in response to each of three environmental stressors (nutritional, heat, or genotoxic stress) when applied specifically during sexual maturation. Increased outgrowth of axon-like neurites following adolescent stress is the result of an altered morphologic plasticity in adulthood. Despite remodeling being induced by each of the three stressors, only nutritional stress affects downstream behavior and is dependent on neurexin/nrx-1 Heat or genotoxic stress in adolescence does not alter behavior despite inducing GABAergic neuron remodeling, in a neurexin/nrx-1 independent fashion. Starvation-induced remodeling is also dependent on neuroligin/nlg-1, the canonical binding partner for neurexin/nrx-1, and the transcription factors FOXO/daf-16 and HSF1/hsf-1hsf-1 and daf-16, in addition, each have unique roles in remodeling induced by heat and UV stress. The differential molecular mechanisms underlying GABAergic neuron remodeling in response to different stressors, and the disparate effects of stressors on downstream behavior, are a paradigm for understanding how genetics, environmental exposures, and plasticity may contribute to brain dysfunction in ASDs and schizophrenia.

Autism aging

Many people perceive autism spectrum disorder (ASD) as a childhood disorder, yet ASD is a lifelong condition. Although little is known about the mental and physical health issues of aging individuals with ASD, there are increasing numbers of older adults being diagnosed with ASD. Although there has been a recent "call to action" (to address lack of knowledge and the dearth of services and programs for aging individuals with autism, the authors think it is also important for those who are involved in educational programs related to gerontology and geriatrics settings to be aware of "autism aging." This term conceptualizes the demographics, person and contextual factors, and intellectual awareness of the trends and patterns of ASD as a life course challenge and opportunity for well-being and quality of life. The purposes of this article are to (1) provide a general overview of autism issues and to examine several dimensions of ASD in the context of the emergent and relevant scholarship in the adult and aging domain, (2) propose how to address the "gap" in the literature on autism and aging in terms of a conceptual model and by improving the methodology, and (3) to discuss the implications of these dimensions for educators in gerontology and geriatrics, and for those professionals who work in clinical and health care services. It is the goal of the authors to have this article represent a general introduction to ASD and to be a part of the foundation for educational awareness for educators in gerontology and geriatrics.

The Relationship Among Gastrointestinal Symptoms, Problem Behaviors, and Internalizing Symptoms in Children and Adolescents With Autism Spectrum Disorder

Background: Many individuals with autism spectrum disorder (ASD) have co-occurring gastrointestinal (GI) symptoms, but the etiology is poorly understood. These GI symptoms often coincide with problem behaviors and internalizing symptoms, which reduces the quality of life for these individuals. Methods: This study examined the relationships among GI problems, problem behaviors, and internalizing symptoms in a sample of 340 children and adolescents with ASD who are patients at the University of Missouri Thompson Center for Autism & Neurodevelopmental Disorders. Results: The majority of patients experienced constipation (65%), about half experienced stomachaches or stomach pain (47.9%), and others experienced nausea (23.2%) or diarrhea (29.7%). Young children with aggressive problem behaviors were 11.2% more likely to have co-occurring nausea; whereas, older children showed more complex relationships between internalizing symptoms and GI symptoms. Older children with greater anxiety symptoms were 11% more likely to experience constipation, but 9% less likely to experience stomachaches. Older children with greater withdrawn behavior were 10.9% more likely to experience stomachaches, but 8.7% less likely to experience constipation. Older children with greater somatic complaints were 11.4% more likely to experience nausea and 11.5% more likely to experience stomachaches. Conclusions: Results suggest that the presentation of externalizing problem behavior and internalizing symptoms associated with GI problems differs between young children and older children with ASD. Therefore, behavior may have different relationships with GI symptoms at different ages, which may have implications for the treatment of and clinical approach to GI disturbances in ASD.

Autism spectrum disorders in high secure psychiatric care: a review of literature, future research and clinical directions

Purpose

The purpose of this paper is to review available literature targeting the assessment and management of individuals with an autism spectrum disorder (ASD) admitted to high secure psychiatric care (HSPC). Key areas of examination include the prevalence of ASD in HSPC, how individuals with an ASD differ from other patient groups in clinical and cognitive characteristics, the views of staff regarding patients with an ASD, an exploration of the experiences and quality of life of patients with an ASD, as well as treatment and interventions.

Design/methodology/approach

A review of the published literature.

Findings

Although individuals with an ASD comprise a relatively small proportion of the total HSPC cohort, they appear to be over represented relative to the general population prevalence. Several research projects suggest that individuals with an ASD present with difficulties and needs different to other patient groups, as well as being viewed by staff as potentially vulnerable and requiring a different care approach. Individuals with an ASD report both positive and negative aspects to life in HSPC.

Practical implications

Suggestions are made with regard to how individuals with an ASD might be better managed in HSPC. Following the spirit of various pieces of government legislation such as the Autism Act (2009) and the Equalities Act (2010) the role of a specialist ASD HSPC service is proposed.

Originality/value

This paper provides a detailed review of the research to date exploring the assessment and management of individuals with an ASD detained in HSPC. It outlines key research findings, highlights limitations with it and provides a personal perspective on future research and clinical targets.

Psychosocial Interventions Targeting Social Functioning in Adults on the Autism Spectrum: a Literature Review

PURPOSE OF REVIEW

There is a perceived shortage of evidence-based treatment programs for adults on the autism spectrum. This article reviews the recent research literature on psychosocial/behavioral interventions targeting social functioning in autistic adults without intellectual disability.

RECENT FINDINGS

We identified only 41 peer-reviewed studies published from 1980 to 2017 that tested intervention programs focused on one or more of the behavioral components of social functioning (i.e., social motivation, social anxiety, social cognition, and social skills) in more than one adult with autism spectrum disorder (ASD). The studies demonstrated substantial variability in treatment objectives, intervention procedures, assessment methods, and methodologic quality. The results indicate a strong need for additional research to develop and rigorously test interventions for autistic adults that target the many behavioral components of social functioning and that include procedures to promote generalization of knowledge and skills to community settings.

Disability, functioning, and quality of life among treatment-seeking young autistic adults and its relation to depression, anxiety, and stress

In this study, we consecutively recruited treatment-seeking young autistic adults without intellectual impairment aged 16–30 years who presented to a mental health service and evaluated general health (distress, quality of life, and disability), functioning (work loss days and social functioning), and mood symptoms (depression, anxiety, and stress) in those diagnosed with autism spectrum disorder ( n = 96). This group was compared to young adults presenting to the same service with primary mental health disorders (depression, n = 343; bipolar, n = 132; psychosis, n = 166; and anxiety, n = 303). This study also investigated the influence of mood symptoms on general health and functioning in the autism spectrum disorder group. Young autistic adults reported significant general health and functioning impairments that were of similar degree to those presenting with primary mental health disorders. Interestingly, the autistic group also reported similarly high levels of mood symptoms to those with primary depressive and anxiety disorders. In the autistic group, depressive symptoms were strongly associated with distress, quality of life, and work loss days, while stress symptoms were strongly associated with disability. This study highlights further research, and mental health services are required specifically targeting young autistic adults to address their significant unmet needs.
