Known-groups and convergent validity of the theory of mind task battery in children with autism spectrum disorder.

OBJECTIVES: One of the most promising Theory of Mind (ToM) tests developed for children with ASD is the Theory of Mind Task Battery (ToM-TB). Still, additional psychometric properties of this tool need to be assessed. The main objective of this preregistered study was to investigate the known-groups and convergent validities of the ToM-TB compared to a well-established test used to assess ToM in children with ASD (the Strange Stories Test; SST). METHODS: A total of 68 school-aged children were recruited (34 children with ASD and 34 children with typical development). The groups were matched on sex and age, and on both receptive language abilities and overall cognitive functioning. RESULTS: Regarding the known-groups validity, we found group differences in the performance on the ToM-TB and SST. Additional analyses revealed that this result tended to be more robust for the ToM-TB than for the SST. Regarding convergent validity, we showed that the ToM-TB and SST correlated strongly, for children with ASD and children with typical development. In contrast, we found small correlations of these two tests with social competence in daily life. No evidence was found for greater known-groups or convergent validity of one test compared to the other. CONCLUSION: Our data confirmed the relevance of the ToM-TB and the SST for the assessment of ToM in school-aged children. Future studies should continue to assess the psychometric qualities of various ToM tests to provide reliable information to best guide researchers and clinicians when choosing optimal neuropsychological tools.

Long-range DNA looping and gene expression analyses identify DEXI as an autoimmune disease candidate gene.

The chromosome 16p13 region has been associated with several autoimmune diseases, including type 1 diabetes (T1D) and multiple sclerosis (MS). CLEC16A has been reported as the most likely candidate gene in the region, since it contains the most disease-associated single-nucleotide polymorphisms (SNPs), as well as an imunoreceptor tyrosine-based activation motif. However, here we report that intron 19 of CLEC16A, containing the most autoimmune disease-associated SNPs, appears to behave as a regulatory sequence, affecting the expression of a neighbouring gene, DEXI. The CLEC16A alleles that are protective from T1D and MS are associated with increased expression of DEXI, and no other genes in the region, in two independent monocyte gene expression data sets. Critically, using chromosome conformation capture (3C), we identified physical proximity between the DEXI promoter region and intron 19 of CLEC16A, separated by a loop of >150 kb. In reciprocal experiments, a 20 kb fragment of intron 19 of CLEC16A, containing SNPs associated with T1D and MS, as well as with DEXI expression, interacted with the promotor region of DEXI but not with candidate DNA fragments containing other potential causal genes in the region, including CLEC16A. Intron 19 of CLEC16A is highly enriched for transcription-factor-binding events and markers associated with enhancer activity. Taken together, these data indicate that although the causal variants in the 16p13 region lie within CLEC16A, DEXI is an unappreciated autoimmune disease candidate gene, and illustrate the power of the 3C approach in progressing from genome-wide association studies results to candidate causal genes.

Are there gender-based variations in the presentation of Autism amongst female and male children?

The Questionnaire for Autism Spectrum Conditions (Q-ASC; Attwood, Garnett & Rynkiewicz, 2011) is one of the few screening instruments that includes items designed to assess female-specific ASD-Level 1 traits. This study examined the ability of a modified version of the Q-ASC (Q-ASC-M; Ormond et al., 2018) to differentiate children with and without ASD-Level 1. Participants included 111 parents of autistic children and 212 parents of neurotypical children (5-12 years). Results suggested that the gendered behaviour, sensory sensitivity, compliant behaviours, imagination, and imitation subscales differentiated autistic females from neurotypical females. Compared to autistic males, autistic females had higher scores on gendered behaviour, sensory sensitivity, social masking, and imitation. Results are discussed in relation to early detection of autistic female children.

An Australian Cross-Sectional Survey of Parents' Experiences of Emergency Department Visits Among Children with Autism Spectrum Disorder.

Parents of children with ASD who had attended an Australian emergency department (ED; n = 421) completed a questionnaire relating to their experiences in the ED, including (1) child's reason for presentation and existing comorbidities, (2) quality of care during the visit (3) child's behaviour during visit, e.g. sensory responses to the ED environment, and disruptive behaviours. Children with comorbid ASD and intellectual disability were more likely to present with gastrointestinal issues and seizures, while those with comorbid ASD and oppositional defiant disorder were more likely to present with self-injury. ED staff awareness of ASD-related issues, including communication and expression of pain, were common difficulties for parents. The ED environment (e.g. lights, sounds, waiting areas), exacerbated child anxiety and led to disruptive behaviour.

"Less stress": a pilot study on a cognitive behavioral treatment program for anxiety in children with autism spectrum disorders.

BACKGROUND: Comorbid anxiety disorders are prevalent in children with autism spectrum disorders (ASD), but only a minority receives adequate treatment for anxiety. Cognitive behavioral therapy (CBT) has been shown to be effective in treating anxiety disorders. The objectives of the present pilot study were to test the feasibility of the CBT program "Less stress" for comorbid anxiety disorders in children with ASD and explore whether an improvement in diagnostic outcomes for anxiety disorders and symptoms of anxiety was found after treatment. METHODS: Participants were ten children diagnosed with ASD and anxiety disorders (eight boys, mean age = 9.5 years, range 8 - 12 years). The "Less Stress" program includes three months of weekly treatment sessions followed by three monthly booster sessions. Five therapists participated. A standardized semi-structured diagnostic interview with the mothers was used to assess comorbid disorders. Child anxiety symptoms were measured with the Revised Child Anxiety and Depression Scale (RCADS). RESULTS: The therapists found the manual easy to use but adaptations were necessary, particularly shorter sessions due to frequent (n = 7) comorbid Attention-Deficit/Hyperactivity Disorder. The participants found the program useful and the parents noted that they had learned methods they could continue using after the end of the program.Eight of ten children completed the treatment. Seven of the eight completers benefited from the program. Five of those seven children were free from all anxiety disorders, while two had fewer anxiety disorders. On a group level, a significant mean reduction of anxiety symptoms (RCADS) was found after treatment. CONCLUSION: The therapists found the "Less stress" program to be a feasible intervention in a sample of children with ASD and comorbid anxiety. The significant reduction of anxiety after treatment is promising, but a replication in a larger and more rigorous study is needed to investigate the effectiveness of the intervention.

Am I Autistic? Utility of the Girls Questionnaire for Autism Spectrum Condition as an Autism Assessment in Adult Women.

This study aimed to explore the structure of a modified version of the Girls Questionnaire for Autism Spectrum Condition (GQ-ASC; Attwood et al. 2011) to test its utility as an autism screening measure for adult women. We recruited 672 cisgender and trans women aged between 18 and 72 online. The sample contained 350 autistic women (M age = 36.21, standard deviation [SD] = 10.10) and 322 nonautistic women (M age = 34.83, SD = 9.93), screened using the Autism Quotient. A principal component analysis and parallel analysis revealed a five-component solution that accounted for 40.40% of the total variance. The extracted components appear to be consistent with what is known about the way girls and women display their autistic traits and interpreted as (1) Imagination and play: Describes interest in fantasy, fiction, and reflection on the quality and content of imaginative play in childhood. (2) Camouflaging: Describes effortful attempts to reduce the visibility of autistic traits. (3) Sensory sensitivities: Describes sensory processing hyper- and hyposensitivities across various modalities. (4) Socializing: Describes barriers to social understanding and participation. (5) Interests: Describes age-advanced and nonstereotypically feminine interests. We observed significant differences between autistic and nonautistic women across all extracted components, and the total score. A receiver operating characteristic analysis indicated an excellent level of discrimination. When applying a cutoff score of 57, the GQ-ASC correctly identified 80.0% of cases. The modified GQ-ASC is an effective and highly discriminant screening tool for use in adult autistic women. It provides valuable insight into the shared features and experiences of this underrecognized and underrepresented subset of the autistic community. Lay summary: Why was this study done?: A lot of autistic women do not get an accurate or timely autism diagnosis. We know that when they do receive an autism diagnosis, they often feel stronger in their identity and feel more confident in advocating for their needs. We wanted to find a quick and easy way for professionals to work out which women should be referred for an autism assessment. We also wanted to help autistic women who do not want to have an assessment done feel confident in self-identifying as autistic.What did the researchers do?: We changed the wording of an autism questionnaire that was designed for younger girls, and had 350 adult autistic cisgender and trans women aged between 18 and 71 years complete it. We looked at answers in a way that told us which questions were most useful for telling apart autistic women and nonautistic women.What were the results of the study?: We found that a number of questions were grouped together into different areas that were common for autistic women. These areas were as follows: (1)Imagination and play: Questions about interest in fantasy, fiction, and imaginative play in childhood.(2)Camouflaging: Questions about acting in certain ways to try to hide autistic traits.(3)Sensory sensitivities: Questions about feeling undersensitive or oversensitive to things such as touch, small, taste, and noise.(4)Socializing: Questions about feeling confused in social situations, and finding it difficult to join in.(5)Interests: Questions about interests that are not common for children who are the same age, and interests that are not common for many girls.What do these findings add to what was already known?: There are a lot of ideas about autism that do not always apply to autistic women. These findings will hopefully help professionals and nonexperts understand autistic women better.What are potential weaknesses in the study?: We do not know if any of the 350 autistic women who completed the survey have an intellectual disability, and we do not know if having an intellectual disability will change the results of the study. This is something that will be interesting to look into in the future.How will these findings help autistic adults now and in the future?: The findings of our study can help doctors and mental health professionals work out which women should be assessed for autism. Our findings may also help to change attitudes about who can be autistic, and what autism looks like.

Gender identity, sexual orientation and adverse sexual experiences in autistic females.

BACKGROUND: There is growing recognition that autistic females present with more diverse gender and sexual identities than their non-autistic counterparts. Likewise, autistic females are also at an increased risk of adverse sexual experiences. As higher rates of sexual victimisation are observed in individuals with diverse sexual identities in the broader population, rates of negative sexual experiences among autistic females remain unclear. This study aimed to investigate the representation of gender and sexual diversity within autistic females and examine their rates of regretted, and unwanted, sexual encounters among females with a transgender gender identity and non-heterosexual sexual orientation. METHODS: Two hundred and ninety-five females completed the Sexual Behaviour Scale-III (SBS-III) online. Self-reported gender identity and sexual orientation were compared between 134 autistic (Mage= 26.2 years, SD = 8.7) and 161 non-autistic females (Mage = 22.0 years, SD = 4.6). Differences in the prevalence of negative sexual experiences were compared across diagnosis and each gender identity and sexual orientation label. RESULTS: Autistic females were more likely to identify with a transgender gender identity (p < .05) and non-heterosexual sexual orientation (p < .007) compared to non-autistic females. Autistic homosexual females were more likely to have experienced a range of negative sexual experiences than autistic heterosexual females (OR ≥ 3.29; p < .01) and were more likely to have experienced unwanted sexual experiences than non-autistic females regardless of sexual orientation (OR ≥ 2.38; p < .05). There were no differences in rates of negative sexual experiences between autistic bisexual and both autistic heterosexual and non-autistic bisexual females. Non-autistic bisexual females (OR = 0.24; p = .018) presented with a reduced risk of regretted sexual experiences than non-autistic heterosexual peers. There were no differences in negative sexual experiences across gender identity in the autistic sample. LIMITATIONS: The use of fixed format response items may have restricted participants' abilities to provide rich responses pertaining to their sexual identities and nature of negative sexual experiences. The small number of participants who identified as transgender (n = 40) limits the reliability of results pertaining to sexual experiences across gender identity. Moreover, although multiple recruitment methods were used in this study, non-representative may bias estimates of prevalence rates. Thus, the data may not be representative of the broader population. CONCLUSIONS: Results indicate that autistic females present with greater diversity in their sexual identities than individuals without autism, with those with a homosexual sexual orientation being at greater risk of experiencing adverse sexual encounters. Findings suggest the importance of increased clinical attention to this diversity and the need to provide support to facilitate the development of a healthy sexual identity and reduce the risks identified in this study.

Everyday social and conversation applications of theory-of-mind understanding by children with autism-spectrum disorders or typical development.

Children with autism-spectrum disorders (ASD) often fail laboratory false-belief tests of theory of mind (ToM). Yet how this impacts on their everyday social behavior is less clear, partly owing to uncertainty over which specific everyday conversational and social skills require ToM understanding. A new caregiver-report scale of these everyday applications of ToM was developed and validated in two studies. Study 1 obtained parent ratings of 339 children (85 with autism; 230 with Asperger's; 24 typically-developing) on the new scale and results revealed (a) that the scale had good psychometric properties and (b) that children with ASD had significantly more everyday mindreading difficulties than typical developers. In Study 2, we directly tested links between laboratory ToM and everyday mindreading using teacher ratings on the new scale. The sample of 25 children included 15 with autism and 10 typical developers aged 5-12 years. Children in both groups who passed laboratory ToM tests had fewer everyday mindreading difficulties than those of the same diagnosis who failed. Yet, intriguingly, autistic ToM-passers still had more problems with everyday mindreading than younger typically-developing ToM-failers. The possible roles of family conversation and peer interaction, along with ToM, in everyday social functioning were considered.

Autism spectrum symptomatology in children: the impact of family and peer relationships.

This study examines the potential impact of family conflict and cohesion, and peer support/bullying on children with autism spectrum disorder (ASD). While such impacts have been established for a range of non-ASD childhood disorders, these findings may not generalize to children with ASD because of unique problems in perspective-taking, understanding others' emotion, cognitive rigidity, and social reasoning. A structural model-building approach was used to test the extent to which family and peer variables directly or indirectly affected ASD via child anxiety/depression. The sample (N = 322) consisted of parents of children with ASD referred to two specialist clinics. The sample contained parents of children with Autistic Disorder (n = 76), Asperger Disorder (n = 188), Pervasive Disorder Not Otherwise Specified (n = 21), and children with a non-ASD or no diagnosis (n = 37). Parents completed questionnaires on-line via a secure website. The key findings were that anxiety/depression and ASD symptomatology were significantly related, and family conflict was more predictive of ASD symptomatology than positive family/peer influences. The results point to the utility of expanding interventions to include conflict management for couples, even when conflict and family distress is low. Further research is needed on the potentially different meanings of family cohesion and conflict for children with ASD relative to children without ASD.

Profiling Autism Symptomatology: An Exploration of the Q-ASC Parental Report Scale in Capturing Sex Differences in Autism.

The Questionnaire for Autism Spectrum Conditions (Q-ASC) was developed by Attwood et al. (2011) to identify gender-sensitive profiles of autism symptomatology; prioritise and adjust the direction of clinical interventions; and support positive psychosocial outcomes and prognosis into adulthood. The current research piloted the Q-ASC with parents of 238 children with a clinical diagnosis of ASD-Level 1 (without intellectual or language impairment). Data analysis revealed eight interpretable and reliable components of the Q-ASC using Principle components analysis. Comparisons across age and gender groups found statistically significant mean differences of parent-reported characteristics. The findings from this study aim to identify improvements in the Q-ASC towards the future assessment of the sensitivity and diversity of presentations of autism among female children and adolescents.

A randomized controlled trial of a cognitive behavioural intervention for anger management in children diagnosed with Asperger syndrome.

The purpose of the study described was to evaluate the effectiveness of a cognitive behavioural intervention for anger management with children diagnosed with Asperger syndrome. Forty-five children and their parents were randomly assigned to either intervention or wait-list control conditions. Children in the intervention participated in six 2-h weekly sessions while parents participated in a larger parent group. Parent reports indicated a significant decrease in episodes of anger following intervention and a significant increase in their own confidence in managing anger in their child. Qualitative information gathered from parents and teachers indicated some generalization of strategies learned in the clinic setting to both home and school settings. Limitations of the study and suggestions for future research are also discussed.

Frameworks for behavioral interventions.

This article examines two frameworks for behavioral interventions, namely the developmental stages in friendship skills with remedial strategies for each stage, and modifications to Cognitive Behavior Therapy to accommodate the unusual profile of cognitive skills of people with Asperger disorder.

The construction and evaluation of three measures of affectionate behaviour for children with Asperger's syndrome.

Children with Asperger's syndrome are often reported by their parents as having difficulties communicating affection. This study aimed to develop a valid measure of affectionate behaviour that could be used to investigate and quantify these anecdotal reports and then be used in further intervention research. Using parent and expert focus groups, three measures (Affection for Others Questionnaire, Affection for You Questionnaire and General Affection Questionnaire) were developed with reference to the existing affection literature. The measures were completed by 131 parents of children with a clinician-confirmed diagnosis of Asperger's syndrome. Psychometric assessment of the measures revealed clear factor structures with high internal consistencies and significant concurrent validities. The findings suggest many children with Asperger's syndrome have difficulties with affectionate behaviour that significantly impact their daily functioning and relationships with others, signalling future research needs to develop interventions in this area. Limitations of the research are also discussed.

Increasing the understanding and demonstration of appropriate affection in children with asperger syndrome: a pilot trial.

The study was conducted to examine relationships between affectionate behavior in children with Asperger syndrome and variables likely to influence its expression (e.g., tactile sensitivity, social ability). It also evaluated the impact of a cognitive behavioral intervention that aimed to improve a child's understanding and expression of affection. Twenty-one children, aged 7 to 12 years, participated in the trial. The results showed significant correlations between measures of affection and tactile sensitivity and social ability. After attending the 5-week program, parents identified significant increases in the appropriateness of children's affectionate behavior both towards immediate family and people outside the immediate family, despite reporting no significant changes in their child's general difficulties with affectionate behavior. There was a significant improvement in children's understanding of the purpose of affection. The findings are discussed as well as the limitations of the study.

The Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R): a scale to assist the diagnosis of Autism Spectrum Disorder in adults: an international validation study.

The Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R) is a valid and reliable instrument to assist the diagnosis of adults with Autism Spectrum Disorders (ASD). The 80-question scale was administered to 779 subjects (201 ASD and 578 comparisons). All ASD subjects met inclusion criteria: DSM-IV-TR, ADI/ADOS diagnoses and standardized IQ testing. Mean scores for each of the questions and total mean ASD vs. the comparison groups' scores were significantly different (p < .0001). Concurrent validity with Constantino Social Responsiveness Scale-Adult = 95.59%. Sensitivity = 97%, specificity = 100%, test-retest reliability r = .987. Cronbach alpha coefficients for the subscales and 4 derived factors were good. We conclude that the RAADS-R is a useful adjunct diagnostic tool for adults with ASD.

A randomised controlled trial of a CBT intervention for anxiety in children with Asperger syndrome.

BACKGROUND: The aim of the study was to evaluate the effectiveness of a brief CBT intervention for anxiety with children diagnosed with Asperger syndrome (AS). A second interest was to evaluate whether more intensive parent involvement would increase the child's ability to manage anxiety outside of the clinic setting. METHODS: Seventy-one children aged ten to twelve years were recruited to participate in the anxiety programme. All children were diagnosed with AS and the presence of anxiety symptoms was accepted on parent report via brief interview. Children were randomly assigned to one of three conditions: intervention for child only, intervention for child and parent, wait-list control. RESULTS: The two intervention groups demonstrated significant decreases in parent-reported anxiety symptoms at follow-up and a significant increase in the child's ability to generate positive strategies in an anxiety-provoking situation. There were a number of significant differences between the two interventions to suggest parent involvement as beneficial. CONCLUSIONS: The sample of children with AS in this study presented with a profile of anxiety similar to a sample of clinically diagnosed anxious children. The intervention was endorsed by parents as a useful programme for children diagnosed with Asperger syndrome and exhibiting anxiety symptoms, and active parent involvement enhanced the usefulness of the programme. Limitations of the study and future research are discussed.
