Sensory symptoms associated with autistic traits and anxiety levels in children aged 6-11 years

BACKGROUND

Autism spectrum conditions (ASC) and quantitative autistic traits (QATs) are associated with sensory symptoms, which may contribute to anxiety and adversely affect social and cognitive development. Although sensory symptoms can occur across all senses, the relative roles of specific sensory modalities as contributors to the autistic phenotype and to anxiety are not well understood. The objective of this study was to examine which sensory symptoms were most predictive of high anxiety.

METHODS

We recruited 257 female primary caregivers of children aged 6 to 11 years (49% girls) to a questionnaire study comprising parent-report measures for classical QATs (social, communicative, and rigid), autism-related sensorimotor symptoms (visual, auditory, tactile, olfactory, gustatory, vestibular, proprioceptive, and motor), and anxiety symptoms. First, Bayesian stochastic search variable selection (SSVS) was used to identify the most probable sensorimotor predictors of specific QATs as well as diagnosed ASC. Then, the selected predictors were used in another SSVS, using anxiety symptoms as a dependent variable, to identify which of the autism-relevant sensorimotor symptoms were most robustly predictive of anxiety. Finally, the effect sizes of anxiety-related sensory symptoms were estimated with linear regressions.

RESULTS

We found that auditory symptoms and motor difficulties were most predictive of ASC diagnosis. Developmental motor difficulties were also strongly related to all individual QATs, whereas auditory symptoms were more selectively predictive of rigid traits. Tactile symptoms robustly predicted social interaction QATs, and proprioceptive symptoms predicted communicative QATs. Anxiety outcomes were most strongly predicted by difficulties with auditory and olfactory processing.

CONCLUSIONS

The results support the clinical importance of being alert to complaints about sounds and hearing in neurodevelopmental populations, and that auditory processing difficulties may be evaluated as an early marker of poor mental health in children with and without diagnosed autism. Olfactory processing differences appeared to be an anxiety marker less strongly associated with ASC or QATs, while motor difficulties were highly autism-relevant but not equally strongly associated with anxiety outcomes. We suggest that future studies may focus on the mechanisms and consequences of neurodevelopmental central auditory processing dysfunction and its potential relationship to anxiety disorders.

Using Q-sort method to explore autistic students' views of the impacts of their anxiety at school

LAY ABSTRACT

Many autistic students experience anxiety, but there is little research that explores how anxiety might affect autistic students in the school environment. In this study, 45 autistic students, aged 7 to 17 years, completed an online sorting activity to tell us how anxiety impacts them at school. The students were given 21 statements about possible social and academic effects of anxiety (for example, 'When I'm worried it's hard to start my schoolwork' or 'When I'm worried I talk less to my friends or other students'), and sorted them based on how much they agreed each statement was true for them. The three statements most highly rated as being impacted by anxiety were difficulties related to schoolwork. By comparing the information provided by students, six smaller groups of students were identified who sorted the statements in a similar order. These groups show that anxiety affects different autistic students in different ways, including missing school or activities, communicating less with friends and teachers and finding it harder to complete schoolwork. This online sorting activity enabled autistic students themselves to report how anxiety affects them at school. The results suggest that it is important to provide individualised support for autistic students who experience anxiety at school, to reduce the impact of their anxiety on their participation, communication and interactions, and schoolwork. Further research about the effects of anxiety on the academic outcomes of autistic students is also needed.

Autism Spectrum Disorder and Anxiety Among Transgender Youth: Use of the Social Communication Questionnaire (SCQ)

Autism spectrum disorder (ASD) and ASD symptoms are overrepresented among gender-diverse youth across studies. Gender-diverse and ASD youth are at risk for anxiety, but anxiety is unclear among gender-diverse youth with ASD. The Social Communication Questionnaire (SCQ) is a commonly used ASD screener, including in multidisciplinary gender-affirming programs, but scholars have disagreed on the most optimal cut-off score. To date, no study has investigated the sensitivity and specificity of its established cut-off score of 15 with a sample of transgender youth. Gaining more accurate information about the utility of ASD screening tools with gender diverse youth is critical in order to help refer youth to needed services. Among a sample of 325 transgender youth, this study sought to determine an optimal cut-off score for the SCQ, the prevalence of ASD and ASD symptoms, and the relationship between ASD and anxiety within this population. The current study found that a lower cut-off score of 11 yielded optimal sensitivity and specificity (i.e., the best balance of accurately identifying individuals with ASD based on the screener), and analyses found an overrepresentation of ASD (5.2%) and ASD traits (12.1%). Transgender youth with ASD or ASD symptoms had higher anxiety, and all youth perceived themselves as more anxious than their parents. Future research is needed to identify the needs of this population, with particular consideration for the lived experiences of gender diverse and transgender youth.

School distress and the school attendance crisis: a story dominated by neurodivergence and unmet need

Background

The Covid-19 pandemic has brought into sharp focus a school attendance crisis in many countries, although this likely pre-dates the pandemic. Children and young people (CYP) struggling to attend school often display extreme emotional distress before/during/after school. We term this School Distress. Here we sought to elucidate the characteristics of the CYP struggling to attend school in the United Kingdom.

Methods

Using a case-control, concurrent embedded mixed-method research design, 947 parents of CYP with experience of School Distress completed a bespoke online questionnaire (February/March 2022), alongside an age-matched control group (n = 149) and a smaller group of parents who electively home-educate (n = 25).

Results

In 94.3% of cases, school attendance problems were underpinned by significant emotional distress, with often harrowing accounts of this distress provided by parents. While the mean age of the CYP in this sample was 11.6 years (StDev 3.1 years), their School Distress was evident to parents from a much younger age (7.9 years). Notably, 92.1% of CYP currently experiencing School Distress were described as neurodivergent (ND) and 83.4% as autistic. The Odds Ratio of autistic CYP experiencing School Distress was 46.61 [95% CI (24.67, 88.07)]. Autistic CYP displayed School Distress at a significantly earlier age, and it was significantly more enduring. Multi-modal sensory processing difficulties and ADHD (among other neurodivergent conditions) were also commonly associated with School Distress; with School Distress CYP having an average of 3.62 NDs (StDev 2.68). In addition, clinically significant anxiety symptomology (92.5%) and elevated demand avoidance were also pervasive. Mental health difficulties in the absence of a neurodivergent profile were, however, relatively rare (6.17%). Concerningly, despite the striking levels of emotional distress and disability reported by parents, parents also reported a dearth of meaningful support for their CYP at school.

Conclusion

While not a story of exclusivity relating solely to autism, School Distress is a story dominated by complex neurodivergence and a seemingly systemic failure to meet the needs of these CYP. Given the disproportionate number of disabled CYP impacted, we ask whether the United Kingdom is upholding its responsibility to ensure the "right to an education" for all CYP (Human Rights Act 1998).

Coping with uncertainty in everyday situations (CUES©) to address intolerance of uncertainty in autistic children: an intervention feasibility trial

BACKGROUND

Anxiety related to uncertainty is common in autism. Coping with Uncertainty in Everyday Situations (CUES©) is a parent-mediated group intervention aiming to increase autistic children's tolerance to uncertain situations. A pilot study was conducted to test its feasibility and acceptability.

METHODS

Parents of 50 autistic children were randomised to receive CUES© or enhanced services as usual.

RESULTS

All children met the clinical threshold for at least one anxiety disorder. Of the 26 participants randomised to CUES©, 72% attended 4-8 sessions. Parents and therapists reported they found CUES© useful and acceptable.

CONCLUSIONS

Families were willing to be recruited and randomised, the format/content was feasible to deliver, and the outcome measures were acceptable. CUES© should be evaluated in a clinical and cost effectiveness randomised controlled trial.

Brief Report: Family Accommodation is Associated with the Impact of Childhood Anxiety in Autism

Anxiety is commonly experienced by children on the autism spectrum, and can negatively impact their lives. Family accommodation has been linked to the impact of anxiety on the child's life in non-autistic children. This study tested whether the same relationship holds for children on the autism spectrum. A community sample (n = 118) of parents of children on the spectrum completed questionnaires on their child's autism characteristics and severity and impact of their child's anxiety, their own anxiety and family accommodation behaviours. Family accommodation was associated with the impact of child anxiety, over and above anxiety severity of the child and parent. Findings support the involvement of parents in psychosocial support for children on the autism spectrum experiencing anxiety.

The relationshipbetween anxiety and social outcomes in autistic children and adolescents: A meta-analysis

Anxiety is one of the most frequently reported co-occurring conditions for autistic children and adolescents. The relationship between anxiety and social outcomes in autistic youth has been the focus of a range of studies, with mixed results. This meta-analysis aimed to identify the strength of the association between anxiety and a frequently researched social outcome (social competence) in autistic young people and whether that association is influenced by individual or research design factors. A previous preregistered systematic review was updated with a search of the same three databases (CINAHL, ERIC, and PsycINFO) as the original review. Through this, 20 studies with sufficient data on a neurotypically-defined measure of social competence and anxiety were identified. Results were synthesised using a mixed effects model. The meta-analysis on 2,321 participants (from 22 samples) highlighted wide heterogeneity in results. The findings show that anxiety has a significant, small negative impact on social competence (d = - 0.48; 95% CI = - 0.71, - 0.26), meaning that as scores on measures of anxiety increase, scores on measures of social competence decrease. This relationship between anxiety and social competence was moderated by age, becoming weaker as age increased. Whilst this is an important finding for supporting mental health and well-being of autistic young people, the large amount of variance left unexplained suggests that multiple factors, including the use of measures designed for neurotypical people and the potential impact of camouflaging on such measures, need to be considered in future designs.

Brief Report: Prevalence and Predictors of DSM-Specific and Distinct Anxiety in Cognitively Impaired Autistic Preschool Children

Autistic individuals are twice as likely to meet criteria for anxiety than neurotypical children; yet we lack understanding of early presentations of anxiety in young autistic children, especially those with cognitive impairment. This study is the first to utilize an autism-specific anxiety diagnostic interview with 28 preschool cognitively impaired, autistic children and 18 neurotypical, age-matched controls. Results indicate that 64% of autistic children met criteria for DSM-specified or "other specified," herein referred to as "distinct," anxiety disorders; 32% met criteria for multiple anxiety disorders, with phobias occurring most often. Results indicate that anxiety is highly prevalent in cognitively-impaired, autistic preschool children, highlighting the need for developmentally-tailored assessment and treatment in early childhood.

Associations of emotional/behavioral problems with accelerometer-measured sedentary behavior, physical activity and step counts in children with autism spectrum disorder

Background

The evidence for associations of emotional/behavioral status with sedentary behavior (SB), physical activity (PA) and step counts is scarce in children with autism spectrum disorder (ASD). Also, ASD-related deficiencies may affect actual levels of PA. We aimed to describe accelerometer-measured SB, PA and step counts in children with ASD, and to examine the associations of emotional/behavioral problems with SB, PA and step counts after assessing associations between accelerometer-measured SB, PA and step counts and ASD-related deficiencies.

Methods

A total of 93 ASD children, aged 6-9 years, were recruited from the Center for Child and Adolescent Psychology and Behavioral Development of Sun Yat-sen University in Guangzhou, China. Participants wore an accelerometer for seven consecutive days. Of the original 93, 78 participants' accelerometer-measured valid PA were obtained, and the data were shown as time spent in SB, light, moderate, moderate-to-vigorous and vigorous PA, and step counts. Participants' emotional/behavioral problems were assessed via the Strengths and Difficulties Questionnaire (SDQ), and anxiety symptoms were evaluated by the Screen for Child Anxiety Related Emotional Disorders (SCARED). ASD-associated deficiencies include restricted repetitive behaviors (Repetitive Behavior Scale-Revised), poor social competence (Social Responsiveness Scale Second Edition) and motor development restrictions (Developmental Coordination Disorder Questionnaire).

Results

Of the 78 participants, daily vigorous PA (VPA) and moderate-to-vigorous PA (MVPA) averaged 15.62 and 51.95 min, respectively. After adjustment for covariates, SDQ emotional symptoms (β = -0.060, p = 0.028) were inversely associated with the average daily minutes in VPA. Meanwhile, SDQ emotional symptoms (β = -0.033, p = 0.016) were inversely associated with the average daily MVPA minutes in the crude model. After adjustment for covariates, SCARED somatic/panic (β = -0.007, p = 0.040) and generalized anxiety (β = -0.025, p = 0.014) were negatively associated with the average daily VPA minutes; SCARED total anxiety (β = -0.006, p = 0.029) was conversely associated with daily MVPA duration. After adjustment for covariates, no significant associations between accelerometer-measured SB, PA and step counts and ASD-related deficiencies were found (p > 0.05).

Conclusions

Accelerometer-measured SB, PA and step counts showed no associations with ASD-related deficiencies. On this basis, we further found that the emotional symptoms were inversely associated with VPA and MVPA. These results emphasize the importance of VPA and MVPA in children with ASD. The longitudinally investigations on the directionality of these associations between emotional symptoms with VPA and MVPA are needed in the future.

The relationship between social and academic outcomes and anxiety for children and adolescents on the autism spectrum: A systematic review

Anxiety is the most common co-occurring condition in children on the autism spectrum but the potential impacts of anxiety on social and academic outcomes of children on the autism spectrum have not been systematically examined. In this review, 50 studies were identified that explore the relationship between anxiety and scores on social or academic measures in children on the autism spectrum. Social competence was frequently measured, and the findings of these studies were mixed. While other social constructs have received little attention, associations were found between anxiety and victimisation, and anxiety and social relationships. Only three studies focused on the impact of anxiety on scores on academic measures, highlighting the need for further research in this area. Anxiety was most frequently measured using subscales from broader behavioural instruments, which may not capture the range of anxiety symptoms of children on the autism spectrum. Future studies that include multi-informant methodologies and proportional representation of females and children with intellectual disability will further knowledge of the impact of anxiety in children on the spectrum.

Protocol for a longitudinal study investigating the role of anxiety on academic outcomes in children on the autism spectrum

BACKGROUND

Children on the autism spectrum are consistently reported to underachieve compared to ability. In typically developing children, anxiety is a strong predictor of poor school performance. Despite the high prevalence of anxiety disorders among children on the spectrum, the impact of their anxiety on academic achievement is under-researched. The main aim of this project is to determine the moderating role anxiety may have in the development of academic learning behaviours (academic enablers) in children on the spectrum. This project addresses a gap in knowledge about the possible associations between anxiety and academic achievement in children on the spectrum. Understanding these associations opens up the possibility of new intervention pathways to enhance academic outcomes through anxiety reduction/prevention.

METHODS

This longitudinal study will aim to recruit 64 children on the spectrum aged 4-5 years and their parents. Information will be gathered from children, parents and teachers. Children will be randomly assigned to one of two conditions in order to experimentally manipulate anxiety levels in the sample: experimental (to receive an anxiety reduction/prevention program, N = 32) or control (no intervention/treatment as usual, N = 32). The primary outcome measures are child academic skills and enabling behaviours assessed using the Academic Competence Evaluation Scales and the WIAT-II. Anxiety will be assessed through parent and teacher report. Assessments will be conducted at baseline, post-experimental manipulation of anxiety, and within the first year of formal schooling. It is hypothesised that anxiety will moderate the relationship between autism characteristics and academic enablers.

DISSEMINATION

Results will be disseminated through peer-reviewed manuscripts and conference presentations. Lay summaries will be provided to all participants and available on the research centre website.

The Impact of Anxiety in Children on the Autism Spectrum

The recognition of anxiety as one of the most commonly co-occurring diagnoses for individuals on the autism spectrum has led to increased research on symptomatology and treatment, but there is limited research documenting the impact of this anxiety. To address this, this study reports on the Child Anxiety Life Interference Scale (CALIS, parent version) in a community sample of 121 parents of children on the autism spectrum. Scores indicate that the anxiety is impacting upon the child's engagement in activities both in and outside of home as well as impacting upon parent life. Explanatory variables differed for CALIS subscales. As the child's difficulties with uncertainty and parent level of anxiety were the variables that explained the most variance, these may be important foci for effective interventions.

The Impact of Anxiety on the Participation of Children on the Autism Spectrum

Anxiety is common in children on the autism spectrum, however its impacts are not fully understood. Participation is an important outcome, linked to the health and wellbeing of children. This study examined the relationship between anxiety and participation using parent reports for 131 children on the autism spectrum, aged 6-13 years. Hierarchical multiple regressions explored child and family factors in relation to participation in Home and Community settings. Anxiety was a unique, significant predictor of the frequency of children's participation (but not involvement in activities) in both settings, when controlling for autism characteristics, communication skills and family income. Anxiety symptomatology may contribute to the less frequent participation of children on the autism spectrum in home and community activities.

"My cheeks get red and my brain gets scared": A computer assisted interview to explore experiences of anxiety in young children on the autism spectrum

BACKGROUND

Anxiety symptoms are common in children on the autism spectrum and may be present at an early age. While a multi-informant approach is considered best practice in the assessment of anxiety, self-reports from young children on the autism spectrum are rarely included.

AIMS

The aim of this study was to utilise a computer-assisted interview procedure incorporating visual prompts to elicit the viewpoints of children about their experiences of anxiety.

METHODS AND PROCEDURES

Ten children aged 5-8 years who were diagnosed on the autism spectrum completed the interview. Directed content analysis was used to explore the data generated in the interview.

OUTCOMES AND RESULTS

A wide range of situations that trigger anxiety, and responses to anxiety, were reported across the participant group. These responses may be unrecognised as anxiety by others. The children provided positive feedback on the use of the computer-assisted interview.

CONCLUSIONS AND IMPLICATIONS

The child's own self-report can inform parents and professionals of the situations which make them more or less anxious and the behaviours that they use to communicate their anxiety in that specific situation. The use of a computer-assisted interview may be an effective method to support self-report of anxiety-related experiences for young children on the autism spectrum.

Case study: identification of anxiety and subsequent intervention in an adolescent male with autism, severe intellectual disability and self-injurious behaviour

Introduction: Anxiety disorders are highly prevalent in individuals with autism spectrum disorder (ASD), but knowledge is limited regarding identification and treatment of these disorders in individuals with ASD and more severe levels of intellectual disability (ID). The current case study aims to explore and describe the inpatient, psychiatric assessment in an adolescent male with ASD, severe ID and self-injurious behaviour (SIB) who was diagnosed with a co-occurring anxiety disorder. The study further aims to explore the implications of this diagnosis for subsequent intervention and care, including management of SIB. Materials and methods: Case study including multimodal, psychiatric assessment and subsequent intervention. Results: Following changes in care strategies attempting to incorporate the understanding of anxiety/trauma as contributing to SIB, a reduction of SIB was observed, and this reduced frequency was maintained when the patient was discharged from the inpatient setting. Conclusions: Though no causal inferences are possible, these experiences indicate that further research is needed regarding possible associations between SIB and anxiety in individuals with ASD, including implications for treatment. Experiences from the current case further indicate that it is possible to recognize and diagnose anxiety disorder in complex cases involving ASD, severe ID, limited verbal language skills, and severe SIB.

Caregiver- and Child-Reported Anxiety Using an Autism-Specific Measure: Measurement Properties and Correlates of the Anxiety Scale for Children with Autism Spectrum Disorder (ASC-ASD) in Verbal Young People with ASD

Identifying and measuring anxiety in young people on the autism spectrum can be challenging. The present study investigated the use of the Anxiety Scale for Children with Autism Spectrum Disorder (ASC-ASD), a self- and caregiver-rated screening tool in a Singaporean sample of ninety-one verbal autistic youths and their caregivers. Internal consistency ranged from satisfactory to desirable (α = .74-.92). Convergent validity with medium-large effect size was established using a structured diagnostic interview, the Mini-International Neuropsychiatric Interview for Children and Adolescents (MINI-KID). ASC-ASD scores were positively associated with autistic symptoms and response patterns indicated strong endorsement of autism-specific items. The findings are discussed in relation to existing literature on assessment of anxiety in ASD and in light of the study's strengths and limitations.

A Scoping Review of Anxiety in Young Children with Autism Spectrum Disorder

Research on anxiety in children and adolescents with autism spectrum disorder (ASD) has burgeoned in the past 15 years. Most of the research has focused on school-age children, ages 6 to 18 years. Yet, recent studies suggest that anxiety can emerge in young children, under 6 years, with ASD. This scoping review synthesized the literature on anxiety in young children with ASD. Three domains of anxiety research were reviewed: (a) prevalence/severity, phenomenology, and course; (b) correlates; and (c) treatment. Four online databases were searched from the start of the database until March 2020. Keywords pertaining to anxiety, autism, and young children were entered. The search identified 44 articles for inclusion. These studies varied with respect to sample source, informants, and measures to assess anxiety. The overall prevalence of anxiety ranged from 1.6 to 62%. Sixteen of 17 studies found that young children with ASD had higher levels of anxiety compared to various control groups. A variety of DSM anxiety symptoms and disorders were present in young children with the most common symptoms being specific, social, and generalized fears. Correlates of anxiety included sensory over-responsivity, sleep disturbance, aggression/defiance, and attention deficit/hyperactivity disorder. Three cognitive behavioral treatment studies for anxiety and one developmental intervention targeting ASD symptoms showed promise in reducing anxiety. Findings indicate an early emergence of anxiety in some children with ASD. Further research on the measurement, pathophysiology, and treatment of anxiety in early childhood is critical to improving outcomes in children with ASD. LAY SUMMARY: This scoping review synthesizes the literature on anxiety in young children with autism spectrum disorder (ASD). Results indicate that children with ASD have higher levels of anxiety than children without ASD. Potential factors that could be contributing to anxiety include sensory, sleep, and behavioral problems. Preliminary studies show that anxiety can improve with cognitive behavioral treatment. These findings suggest that research on anxiety in young children with ASD should be prioritized to improve mental health outcomes.

Development and Initial Evaluation of the Anxiety Scale for Autism-Adults

Background

Anxiety is highly prevalent in autistic adults and can cause a significant impact on functioning and quality of life. There are no existing measures of anxiety designed and validated specifically for autistic adults. In this study, we aimed to adapt an existing anxiety measure designed for autistic children, in collaboration with autistic adults and other professionals, to make it suitable for use for autistic adults and to examine the measurement properties of the newly designed measure.

Methods

Through consultation with autistic adults and professionals working with autistic people, we developed a preliminary self-report anxiety measure. Five hundred fifty-one autistic adults completed the measure and another measure of anxiety and depression (the Hospital Anxiety and Depression Scale). Participants completed measures again after 1 month to determine test/retest reliability. We split the sample to enable exploratory and confirmatory factor analyses to be undertaken on different samples. We conducted internal consistency and convergent and divergent validity analyses. We completed receiver operator curve (ROC) analyses to investigate sensitivity and specificity and identify an indicative clinical cutoff.

Results

Our findings indicate that the Anxiety Scale for Autism-Adults (ASA-A) has promising psychometric properties. Factor analysis indicated that a bifactor solution with orthogonal general and specific factors was an adequate fit and that minimal measurement bias would occur if the scale were treated as unidimensional, so the total score could be used as a valid measure of anxiety. We identified a General Anxiety factor and three group factors (Social Anxiety, Uncertainty, and Anxious Arousal). ROC analysis indicated a score of 28 could be considered an indicative clinical cutoff.

Conclusion

The ASA-A is the first self-report anxiety questionnaire specifically developed and validated for autistic adults. Preliminary evaluation of the measurement properties indicates that the scale will be a useful tool in research and clinical contexts.

Lay summary

Why was this study done?: Autistic adults commonly experience anxiety, which can have a huge impact on their quality of life. One way of identifying anxiety is by using questionnaires. Research shows that anxiety may be experienced differently by autistic people, and so, questionnaires that have been created for neurotypical adults may not be suitable for autistic adults. At present, there are no anxiety measures that have been adapted specifically for autistic adults.What was the purpose of this study?: Our team previously created an anxiety questionnaire for autistic children-the Anxiety Scale for Children-Autism Spectrum Disorder (ASC-ASD). We aimed to adapt this questionnaire to make it suitable for autistic adults.What did the researchers do?: We met with autistic people and professionals, and asked them how to change the ASC-ASD to make it suitable for measuring anxiety in autistic adults. We discussed whether the questions were appropriate for adults, if the questions were worded clearly, and if anything was missing. We then created the Anxiety Scale for Autism-Adults (ASA-A).What did we find?: Once the questionnaire was created, 551 autistic adults with anxiety completed it. We used this information to test whether the questionnaire was a good way of measuring anxiety. We also tested the questionnaire subscales, which were as follows: Anxious Arousal, Social Anxiety, and Uncertainty. We found that the questionnaire is useful in giving a total score for anxiety, and we found that a score of 28 indicated anxiety that was likely to have an impact on someone's daily life. Each subscale was also found to be useful for providing a "profile" of anxiety.What do these findings add to what was already known?: These findings suggest that the ASA-A is a good way of measuring anxiety in autistic adults. This is the first anxiety measure to be developed for autistic adults. This study is the first step toward testing out the usefulness of the measure. We hope that our questionnaire can be further tested and that in the future it will help to identify anxiety experienced by autistic adults more accurately. This would mean that the results of future studies are more likely to be valid, which should help improve what we know about the anxiety autistic people experience.What are potential weaknesses in the study?: We used another anxiety measure to measure anxiety levels when testing what the cutoff score should be on our measure. A clinical interview may have been a more accurate way, and should be done in the future to check that the cutoff of 28 on the ASA-A is still appropriate for identifying anxiety in autistic adults.We recruited autistic adults from a database of people who are interested in taking part in research. This helped us to get enough people to test the questionnaire, but we cannot tell how well these results apply to all autistic people. Testing the questionnaire with other autistic people, including those who may need some assistance with reading or who may need someone else to complete it on their behalf will let us know.How will these findings help autistic adults now or in the future?: The final questionnaire, the ASA-A, has been shown to accurately measure anxiety in autistic adults who do not have an intellectual disability. The questionnaire will be helpful in both clinical and research services.

Family accommodation of anxiety in a community sample of children on the autism spectrum

Anxiety is recognised as one of the most common co-occurring conditions for individuals with a diagnosis on the autism spectrum, with approximately 40 % of children on the spectrum receiving a clinical diagnosis of an anxiety disorder. To date, research has tended to focus upon understanding presentation and evaluating treatment, with little focus on assessing systemic factors, such as the way that family members accommodate the anxiety. This study aimed to investigate the relationship between parent and child anxiety levels and child autism characteristics on the four domains of family accommodation; Participation, Modification, Distress, and Consequence. A community sample (n = 132) of parents of children on the spectrum completed questionnaires on their child's autism characteristics and anxiety symptomatology as well as their own levels of anxiety and family accommodation behaviours. Regression models identified specific aspects of child anxiety as well as parent anxiety as predictive of family accommodation, with the child's difficulties with uncertainty being a consistent predictor of all four domains. Clinical and research implications of this study, including the importance of understanding similarities or differences in the nature and consequence of family accommodation in children on the autism spectrum, are discussed.

Anxiety in young people with autism spectrum disorder: Common and autism-related anxiety experiences and their associations with individual characteristics

Anxiety is common in autism spectrum disorder. Many anxiety symptoms in autism spectrum disorder are consistent with Diagnostic and Statistical Manual of Mental Disorders (5th ed.) anxiety disorders (termed "common" anxieties), but others may be qualitatively different, likely relating to autism spectrum disorder traits (herein termed "autism-related" anxieties). To date, few studies have examined both "common" and "autism-related" anxiety experiences in autism spectrum disorder. We explored caregiver-reported Spence Children's Anxiety Scale-Parent version data from a multi-site (United Kingdom, Singapore, and United States) pooled database of 870 6- to 18-year-old participants with autism spectrum disorder, of whom 287 provided at least one written response to the optional open-ended Spence Children's Anxiety Scale-Parent item 39 ("Is there anything else your child is afraid of?"). Responses were thematically coded to explore (a) common and autism-related anxiety presentations and (b) their relationship with young people's characteristics. Nearly half of the responses were autism-related anxieties (mostly sensory, uncommon, or idiosyncratic specific phobias and worries about change and unpredictability). The other half described additional common anxieties not covered in the original measure (mostly social, weather and environmental disasters, and animals). Caregivers of participants who were more severely affected by autism spectrum disorder symptoms reported more autism-related, as compared to common, additional anxieties. Implications for the assessment and understanding of anxiety in autism are discussed.

Exploring Anxiety at Home, School, and in the Community Through Self-Report From Children on the Autism Spectrum

Research investigating anxiety in children on the autism spectrum usually reports caregiver rather than self-report perspectives. This study aimed to document children's own descriptions of their anxiety symptomatology by combining profiles on a standardized autism-specific self-report measure of anxiety (ASC-ASD-C) with the answers from closed- and open-answer questions about anxiety across home, school, and community settings. Across the sample of 113 children on the spectrum aged 6-14 years, the two most frequently endorsed items on the ASC-ASD-C were from the Uncertainty and Performance Anxiety subscales, and the least endorsed were both from the Anxious Arousal subscale. Almost all (96.5%) of the children on the spectrum reported experiencing anxiety in at least one setting, with 40.7% reporting anxiety in all three contexts (home, school, and community). Approximately half of the sample felt their anxiety goes unrecognized by others at school and almost 60% felt it was unrecognized by others when out in the community. The proportion of children reporting having someone to help reduce their anxiety differed across home (86%), school (76%), and community (45%) settings. This highlights the importance of understanding anxiety and its impact, not only within the context of autism but also for each particular child. Autism Res 2020, 13: 603-614. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: There has been a lot of research focusing on anxiety and autism, but most of it has used parent reports, rather than asking the child themselves. This study summarizes data from 113 children on the autism spectrum, aged 6-14 years. It reports the symptoms of anxiety that these children most and least commonly experience. The results suggest only 40-50% of children feel that others are able to recognize their anxiety at school and when out in the community, suggesting that more training is needed to help adults in these settings to recognize and support anxiety.

The Developmental Behaviour Checklist (DBC) Profile in Young Children on the Autism Spectrum: The Impact of Child and Family Factors

High levels of emotional/behavioural difficulties are frequently reported in children on the autism spectrum. However, given the diversity in profiles, there is a need to explore such behaviours in relation to individual factors. Parents of 130 children aged 4-5 on the autism spectrum completed measures of behaviour and adaptive behaviour. Hierarchical multiple regressions explored child and family characteristics in relation to children's emotional/behavioural presentation. Different aspects of the behavioural profile were associated with different factors, with child autism characteristics, medication use, and parent mental health making significant unique contributions to a range of behavioural subscales. Understanding individual profiles beyond total scores is therefore needed to truly understand the emotional and behavioural profile of specific subgroups.

Mental Health Correlates of Autism Spectrum Disorder in Gender Diverse Young People: Evidence from a Specialised Child and Adolescent Gender Clinic in Australia

Research suggests an overrepresentation of autism spectrum diagnoses (ASD) or autistic traits in gender diverse samples, particularly in children and adolescents. Using data from the GENTLE (GENder identiTy Longitudinal Experience) Cohort at the Gender Diversity Service at the Perth Children's Hospital, the primary objective of the current retrospective chart review was to explore psychopathology and quality of life in gender diverse children with co-occurring ASD relative to gender diverse children and adolescents without ASD. The Social Responsiveness Scale (Second Edition) generates a Diagnostic and Statistical Manual of Mental Disorders (DSM-5) score indicating a likely clinical ASD diagnosis, which was used to partition participants into two groups (indicated ASD, n = 19) (no ASD indicated, n = 60). Indicated ASD was far higher than would be expected compared to general population estimates. Indicated ASD on the Social Responsiveness Scale 2 (SRS 2) was also a significant predictor of Internalising behaviours (Anxious/Depressed, Withdrawn/Depressed, Somatic Complaints, Thought Problems subscales) on the Youth Self Report. Indicated ASD was also a significant predictor of scores on all subscales of the Paediatric Quality of Life Inventory. The current findings indicate that gender diverse children and adolescents with indicated ASD comprise an especially vulnerable group that are at marked risk of mental health difficulties, particularly internalising disorders, and poor quality of life outcomes. Services working with gender diverse young people should screen for ASD, and also provide pathways to appropriate care for the commonly associated mental health difficulties.

Anxiety in 3- to 7-year-old children with autism spectrum disorder seeking treatment for disruptive behavior

Anxiety is a common and impairing problem in children with autism spectrum disorder, but little is known about it in preschool children with autism spectrum disorder. This article reports on the characteristics of anxiety symptoms in young children with autism spectrum disorder using a parent-completed rating scale. One hundred and eighty children (age 3-7 years) participated in a clinical trial of parent training for disruptive behaviors. Anxiety was measured as part of pre-treatment subject characterization with 16 items from the Early Childhood Inventory, a parent-completed scale on child psychiatric symptoms. Parents also completed other measures of behavioral problems. Sixty-seven percent of children were rated by their parents as having two or more clinically significant symptoms of anxiety. There were no differences in the Early Childhood Inventory anxiety severity scores of children with IQ < 70 and those with ⩾70. Higher levels of anxiety were associated with severity of oppositional defiant behavior and social disability. Anxiety symptoms are common in preschoolers with autism spectrum disorder. These findings are consistent with earlier work in school-age children with autism spectrum disorder. There were no differences in anxiety between children with IQ below 70 and those with IQ of 70 and above. Social withdrawal and oppositional behavior were associated with anxiety in young children with autism spectrum disorder.

Parent descriptions of the presentation and management of anxiousness in children on the autism spectrum

The complex interaction between anxiety and autism has led to debate about the presentation of anxiety in individuals on the spectrum and questions about the extent to which traditional checklists assess the entire range of symptomatology. Moreover, studies to date have not explored how the presentation of anxiety may differ between settings. Through a combination of open-ended questions, closed questions and standardised measures, parents of 173 children (aged 6–13) on the autism spectrum provided (1) descriptors of their child’s anxiety at home, school and in the community and (2) strategies used to reduce their child’s anxiety in each setting. Over half (52.6%) felt their child was anxious at home, 77.6% at school and 76.2% in the community. Parents reported differing presentations of anxiety between settings, with the majority of descriptions relating to observable, behavioural changes (e.g. hides/shuts down, repetitive behaviours) rather than cognitive or physiological signs. Parents also reported using different strategies across settings. The use of open-ended questions allowed the identification of signs of anxiety not explored within traditional questionnaires and highlighted the potential for signs to vary across settings. This knowledge is critical to inform the development or adaptations of anxiety measures and interventions.
