Brief Report: Social Anxiety in Autism Spectrum Disorder is Based on Deficits in Social Competence

The differential diagnosis of autism spectrum disorder in adults

INTRODUCTION

Diagnosing autism spectrum disorder (ASD) in adults is challenging due to its heterogeneity and symptom overlap with other conditions. Making an accurate diagnosis can be difficult and overwhelming but is vital for proper accommodations and interventions while avoiding unproductive or harmful treatments.

AREAS COVERED

The authors have based their review on a comprehensive literature search using PubMed, PsycINFO, and Google Scholar to identify relevant recommendations, diagnostic tools, and common differential diagnoses for adults with ASD. A clinical framework is provided based on the DSM-5 criteria, starting with an evaluation of childhood symptom onset and persistent manifestations of the core criteria - social and communication impairment, along with restricted, repetitive behaviors. Conditions with overlapping presentations, including personality disorders, anxiety, depression, obsessive-compulsive disorder, attention-deficit/hyperactivity disorder, and schizophrenia, are discussed, as well as challenges in differentiating these from ASD.

EXPERT OPINION

Many factors complicate diagnosing ASD in adults - such as skewed public perception or misinformation spread on social media. Existing tools frequently miss subtle or atypical presentations, particularly in underdiagnosed groups like women and older adults. Promising advances in machine learning and artificial intelligence will hopefully improve diagnostic precision in the future. Up-to-date clinician training and large-scale research remain paramount for refining adult ASD diagnosis.

Factor Analysis of the Autism Spectrum Rating Scales Parent Report 6-18 in a Complex Community Sample

There is a need for research on autism questionnaire psychometrics outside of the standardization sample. This study investigated the factor structure of the Autism Spectrum Rating Scales-Parent report for ages 6-18 (ASRSp6) in a well-characterized community sample of 696 children (autism [AUT] n = 231; non-autism [NOT] n = 465; X̄age = 10.03) prospectively evaluated with the Autism Diagnostic Observation Schedule-2, a gold-standard autism diagnostic measure. The original author-identified structure demonstrated poor model fit. Exploratory Factor Analysis with a randomly selected half of the sample (n = 346) suggested retaining 17-items on three factors (Rigid/Sensory, Social, and Executive Function [EF]), explaining 55% of the variance. Confirmatory Factor Analysis with the remaining participants (n = 350) indicated good model fit. Partial measurement invariance was observed for diagnostic (AUT/NOT) and gender (male/female) groups. Correlations with the DSM-5p6 (an ASRSp6 scale) were high. Mean differences were observed between AUT/NOT groups for Social; when controlling for age, marginal differences (p = 0.02 - 0.03) were observed for all factors but EF. Social also demonstrated significant AUC regardless of control variables. However, AUC values for Social and other factors, while significant, were in the poor range; correlations with ADOS-2 scores were weak or non-significant. Despite improving the factor structure, the Total-17 does not appear to measure ASD-specific traits. However, these findings provide a basis for further research on ASD questionnaires.

Browsing problematic social media use in autism spectrum disorder: The role of social anxiety

Accessing the Internet is one of the most frequent free-time activities among autistic and non-autistic adolescents. Autistic individuals may experience communicative benefits from using the Internet. However, they may also be at risk of developing Problematic Social Media Use (PSMU). To date, PSMU in autistic adolescents remains underinvestigated, and no research has analyzed the role of emotional correlates. The present study aims to investigate possible differences in terms of PSMU comparing autistic participants to their non-autistic peers, and examine the role of two dimensions of social anxiety (i.e., humiliation/refusal and performance anxiety) as reported by both children and parents in worsening the levels of PSMU. A total of 183 participants (76 on the autism spectrum), aged (8-17 years) participated in the study. Questionnaires on social media use and on social anxiety were administered. Moreover, parents of the participants were asked to complete a questionnaire related to their children's social anxiety. Results showed similar levels of PSMU across the two groups. However, a different pattern of relationships between PSMU and age, and the two dimensions of social anxiety was observed in autistic adolescents as compared to the non-autistic peers, revealing that individual characteristics and specific social anxiety beliefs might be relevant to understanding PSMU in autism. The clinical and preventive implications of these findings are discussed.

A critical hit: Dungeons and Dragons as a buff for autistic people

LAY ABSTRACT

Tabletop role-playing games (TTRPGs) are popular hobbies that may offer specific social benefits for autistic people. This study investigated the ability of TTRPGs to provide a safe space where autistic adults could develop relationships with other autistic adults while engaging in character and world-building. A group of eight autistic adults were split into two groups and taken through a short-form online Dungeons and Dragons campaign over 6 weeks run by one of the researchers. The researcher then led a series of individual semi-structured interviews discussing how participants felt interacting in and out of the TTRPG. Several key themes were identified as important aspects of why autistic people could benefit from such an environment. Analysis showed that while real-life interactions could be challenging, in TTRPG play, they felt they experienced significantly fewer struggles. Results suggested that TTRPGs can provide a safe space environment where autistic adults can engage in productive social interactions with like-minded individuals. It also may allow autistic participants to experience 'bleed' or the ability to take on a new character that changes the way they feel about themselves outside of the game. Future directions for this work are discussed.

Understanding Mechanisms that Maintain Social Anxiety Disorder in Autistic Individuals Through the Clark and Wells (1995) Model and Beyond: A Systematic Review

Given the high co-occurrence of social anxiety in autism, no reviews to date have explored how cognitive and behavioural mechanisms identified to maintain social anxiety in non-autistic individuals may operate in autistic individuals. This systematic review evaluated: (1) empirical evidence underlying the Clark and Wells (1995) Cognitive Model of Social Anxiety in autistic individuals; (2) how vulnerability factors identified from autism literature (beyond core autistic traits) may be associated with social anxiety beyond the cognitive model. Published peer-reviewed English articles until 27th November 2023 were retrieved from PubMed, EMBASE, Ovid MEDLINE and PsycINFO. Quality appraisal and risk of bias were assessed using The Standard Quality Assessment Criteria for Evaluating Primary Research papers from a Variety of Fields tool. 47 articles met full inclusion criteria and included autistic individuals (with clinical diagnosis), a measure of social anxiety, and a mechanism outlined by either (or both) research questions. The majority of the 3340 participants across studies were male without intellectual disability, White/Caucasian, with 7 studies reporting an average age above 30 years old. Most studies used only self-report measures that may have inflated associations observed between social anxiety and mechanisms. All studies employed cross-sectional design, and no causality inferences could be drawn. Methodological issues around potential construct overlaps between social anxiety and autistic traits are highlighted. Overall, there is evidence in support of the as reported by Clark and Well (in: Heimberg (eds), A cognitive model of social phobia, The Guilford Press, 1995) model, as greater fear of negative evaluation from others, use of safety behaviours and somatic symptoms, and peer victimisation were associated with greater social anxiety. The review contributes evidence in support of autism specific contextual, predisposing/antecedent and maintenance factors of social anxiety beyond the original Clark and Well (in: Heimberg (eds), A cognitive model of social phobia, The Guilford Press, 1995) model. Given the potential for considerable heterogeneity for each highlighted process at an individual level across autistic individuals, clinicians can broaden formulation conversations with autistic clients to understand how autism related factors may influence the development and maintenance of social anxiety symptoms when applying and adapting the Clark and Well (in: Heimberg (eds), A cognitive model of social phobia, The Guilford Press, 1995) model.

A novel screening instrument for the assessment of autism in German language: validation of the German version of the RAADS-R, the RADS-R

The Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R) demonstrated excellent results in its original study, with a sensitivity of 97% and a specificity of 100% (Ritvo et al. in J Autism Dev Disord 41:1076-1089, 2011). As a result, it was included in the National Institute for Health and Care Excellence (NICE) guidelines (Recommendations | Autism spectrum disorder in adults: diagnosis and management | Guidance | NICE, 2022). The questionnaire includes 80 questions across four subcategories (language, social relatedness, circumscribed interests, sensory motor). So far, the subcategory sensory motor has not been addressed in most available instruments, despite being part of the diagnostic criteria specified in DSM-5 (Falkai et al., in Diagnostisches Und Statistisches Manual Psychischer Störungen DSM-5. Hogrefe, 2015) and ICD-11 (ICD-11 for Mortality and Morbidity Statistics, 2022). In our validation study, we tested a translated German version of the questionnaire in 299 individuals (110 persons with ASD according to ICD-10 F84.0, F84.5, 64 persons with an primary mental disorders (PMD), 125 persons with no disorders). To enhance the practical use of the instrument in clinical everyday practice, the questionnaire was completed by the participants without the presence of a clinician-unlike the original study. Psychiatric diagnoses were established following the highest standards, and psychometric properties were calculated using established protocols. The German version of the RADS-R yielded very good results, with a high sensitivity of 92.5% and a high specificity of 93.6%. The area under the curve (AUC = 0.976), indicates a high quality and discriminatory power of RADS-R. Furthermore, the ROC curve analysis showed that the optimal threshold to distinguish between the ASD and non-ASD groups in the German version of the RAADS-R is a score of 81. In comparison to the RADS-R, the co-administered instruments Social Responsiveness Scale (SRS), Autism Spectrum Quotient (AQ), and Empathy Quotient (EQ) each showed slightly better specificity but worse sensitivity in this sample.The study included individuals already diagnosed with ASD according to ICD-10 (F84.0, F84.5), with or without an primary mental disorders, preventing us from identifying the influence of comorbidities on the RADS-R results. In addition, a self-report questionnaire has generally only limited objectivity and may allow for false representation of the symptoms. The RADS-R compares well with other questionnaires and can provide valuable additional information. It could turn out to be a helpful diagnostic tool for patients in Germany. We propose naming the German version RADS-R (Ritvo Autism Diagnostic Scale - rRevised) to reflect the change in terminology.

It is More Anxiousness than Role-playing: Social Camouflaging Conceptualization Among Adults on the Autism Spectrum Compared to Persons with Social Anxiety Disorder

PURPOSE

Autistic individuals consider social camouflaging, e.g., masking autistic traits or social skills compensation, as exhausting and effortful, often leading to diminished well-being or burnout, as well as adaptive for satisfying social interactions. Developing camouflaging may result in isolation, social avoidance, increased self-stigmatization, and misdiagnosis, including social anxiety disorder. The study's objective was to explore and conceptualize social camouflaging, with a particular focus on social anxiety symptoms, autistic burnout, and public stigma, among autistic individuals, with two comparative samples: with social anxiety disorder (SAD) and dual diagnoses (SAD + ASD).

METHODS

254 individuals participated in the study (including 186 females, 148 with ASD diagnosis). CAT-Q, AQ-10, AASPIRE's Autistic Burnout Scale, LSAS-SR, The Perceived Public Stigma Scale were used.

RESULTS

The findings suggest differences in the interrelation dynamics between the samples studied, with autistic burnout and social anxiety symptoms of essential significance in camouflaging strategies, and autistic traits being of secondary importance. Structural equation models showed that the proposed conceptualization, with camouflaging and autistic burnout as the outcome variables, exhibited acceptable fit, implying that this strategy is costly and may result in exhaustion.

CONCLUSION

The total score of camouflaging did not differ between the groups studied, suggesting that a tendency to camouflage is rather transdiagnostic, deriving from anxiousness and negative self-perception, not being autistic per se.

Autistic traits predict social avoidance and distress: The chain mediating role of perceived stress and interpersonal alienation

Social avoidance and distress are the primary aspects of social anxiety. Nonautistic people with high levels of autistic traits are more likely to exhibit social avoidance and distress. However, research has yet to reveal how autistic traits induce social avoidance and distress. To fill this gap, the present study recruited 708 participants to complete the 25-item Autism Spectrum Quotient, Social Avoidance and Distress Scale, Chinese Perceived Stress Scale, and Interpersonal Alienation Subscale. The results indicated that autistic traits significantly predicted social avoidance and distress in nonautistic people. In addition, autistic traits induced social avoidance and distress through perceived stress and interpersonal alienation, respectively. Importantly, perceived stress and interpersonal alienation (including the subdimensions of interpersonal alienation: sense of loneliness, sense of social isolation, and alienation between family members) partially mediated the relationships between autistic traits and social avoidance and distress. Overall, autistic traits predict social avoidance and distress via perceived stress and interpersonal alienation. This finding extends the hypothetical model of clinical anxiety in autism spectrum disorders. Furthermore, reducing perceived stress and interpersonal alienation in nonautistic people with high levels of autistic traits may be a valid intervention method to prevent and eliminate their social avoidance and distress.

Correlations Between the Development of Social Anxiety and Individuals With Autism Spectrum Disorder: A Systematic Review

It is well established that people with autism spectrum disorder (ASD) have significantly higher rates of social anxiety, given that most autistic individuals experience socio-communication impairments, a deficit in social competence, and their experience in social engagement situations often leads to discomfort in social settings. Literature also finds that individuals on the spectrum are often at a higher risk of developing social anxiety, which is often misinterpreted as social anxiety disorder (SAD) leading to delays in the clinical diagnosis of ASD. Hence, an improved understanding of specific factors that put ASD individuals at risk of developing social anxiety will aid research to differentiate between social anxiety among individuals with ASD compared to non-ASD individuals facing social anxiety in general. This systematic review study focuses on empirical literature that provides evidence for reasons contributing to social anxiety among individuals with ASD. Following the systematic review methodology, the study evaluates 10 research papers. The results revealed several correlations that can be useful in helping explain why individuals with ASD are at a higher risk of developing SAD. Individuals with ASD often suffer severe social anxiety because they struggle to understand social cues, maintain eye contact, interpret non-verbal cues like facial expressions or body language, or participate in reciprocal conversation. Other cognitive factors include a preference toward predictable situations, intolerance for uncertainty, and a tendency toward rigid thinking patterns. Unpredictability in social settings often heightens anxiety levels in ASD individuals, making them avoid such situations. Other risk factors include emotional recognition impairments and reduced social competence. These findings serve as a guide to developing better intervention strategies to help individuals with ASD to overcome social anxiety.

'They ask no questions and pass no criticism': A mixed-methods study exploring pet ownership in autism

Many autistic people cite a strong attachment to animals, and some studies suggest they may even show a bias towards animals over people. This mixed-methods study explored companion animal attachment in the adult autistic community. In a quantitative study with 735 people, we found that autistic adults were equally attached to their pets as neurotypicals but were less likely to own them, even though pet ownership corresponded with better mental health outcomes. Substituting pets for people also served as a compensatory mechanism for social contact in the autistic sample. In a second qualitative study, we explored the lived experiences of 16 autistic pet owners. The interpretive phenomenological analysis highlighted the benefits and the barriers to animal companionship. Together these mixed methods findings underline how pets improve the lives of their autistic owners. We conclude with specific recommendations for increasing animal companionship opportunities for autistic adults.

Diagnostic Utility of the Gilliam Autism Rating Scales-3rd Edition Parent Report in Clinically Referred Children

There is limited research regarding the Gilliam Autism Rating Scales-3rd Edition (GARS-3) despite its extensive use. A comprehensive diagnostic evaluation, including the Autism Diagnostic Observation Schedule-2nd Edition (ADOS-2) was provided to 186 clinically referred children suspected of autism ([Formula: see text] age = 8.98; Autism [AUT] n = 87; Not Autism [NOT] n = 99). Mean difference analyses, Logistic Regressions, and ROC analyses were non-significant for both Autism Index scores. The author-suggested cutoff score of 70 correctly classified approximately 47% of participants, with false positive rates = 82.83-87.88%. ADOS-2 correlations were significantly lower vis-à-vis the standardization sample. The Social Interaction subscale demonstrated weak, marginal results, and sensitivity/specificity could not be optimized. In its current form, the GARS-3 does not demonstrate adequate criterion validity for use in assessment of complex community samples.
