Previous work shows that, for autistic people, alexithymia, intolerance of uncertainty (IU), and anxiety mediate the relationship between SP differences and RRB. However, these studies use anxiety measures developed for the general population, and more recent evidence suggests that autistic people may have a different anxiety experience. This study aims to extend previous findings by unpacking the anxiety experience for autistic adults in the relationship between SP differences and RRB, using an autism-specific anxiety measure. Data were available from 426 autistic adults. Serial mediation models tested the relationship between SP differences and RRB, with alexithymia, IU, anxious arousal, and social anxiety as mediators. We identified significant direct effects from SP differences to both repetitive motor behaviors (RMB) and insistence on sameness behaviors (ISB). For RMB, we found indirect effects through anxious arousal, alexithymia-anxious arousal, IU-anxious arousal, and alexithymia-IU-anxious arousal. For ISB, we found indirect effects through IU and alexithymia-IU. Thus, different mechanisms may underpin RMB and ISB. Understanding the anxiety experience of autistic people, alongside the role of SP and RRB, is key to providing tailored support, adjustments, and psychological interventions to autistic people. Future research could benefit from directly investigating the impact of strategies to support SP and anxiety.

A Pilot Randomised Control Trial Exploring the Feasibility and Acceptability of Delivering a Personalised Modular Psychological Intervention for Anxiety Experienced by Autistic Adults: Personalised Anxiety Treatment-Autism (PAT-A) / Jacqui RODGERS in Journal of Autism and Developmental Disorders, 54-11 (November)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-11 (November) . - p.4045-4060 Titre : A Pilot Randomised Control Trial Exploring the Feasibility and Acceptability of Delivering a Personalised Modular Psychological Intervention for Anxiety Experienced by Autistic Adults: Personalised Anxiety Treatment-Autism (PAT-A) Type de document : texte imprimé Auteurs : Jacqui RODGERS, Auteur ; Samuel BRICE, Auteur ; Patrick WELSH, Auteur ; Barry INGHAM, Auteur ; Colin WILSON, Auteur ; Gemma EVANS, Auteur ; Katie STEELE, Auteur ; Emily CROPPER, Auteur ; Ann LE COUTEUR, Auteur ; Mark FREESTON, Auteur ; Jeremy R. PARR, Auteur Article en page(s) : p.4045-4060 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Anxiety is commonly experienced by autistic people and impacts on quality of life and social participation. New anxiety interventions are required to effectively meet the needs of autistic people. Personalised Anxiety Treatment-Autism (PAT-A©) is a bespoke, modular approach to treating anxiety in up to 12 sessions. This study explored the feasibility and acceptability of delivering PAT-A© in the UK National Health Service (NHS). A single-blind randomised controlled trial design. Thirty-four autistic adults were recruited via clinical services and randomised to receive either PAT-A© or enhanced treatment as usual (CCSP). Outcome assessments relating to anxiety, quality of life and related constructs were completed at baseline, immediately post intervention; and at 3 and 12 months. Seventy-one percent of the PAT-A© group and 65% of the CCSP met diagnostic threshold for at least three anxiety disorders. Retention was good across both groups, with 82% (N = 14/17) completing the full course of PAT-A© and 71% (N = 12/17) attending both psychoeducational sessions in CCSP. 94% in PAT-A© and 82% in CCSP completed some follow up assessment 3 months post-intervention. Thematic analysis of interview data revealed that many participants valued the personalised approach, developed transferable skills and experienced positive changes to their anxiety. Participants were willing to be recruited and randomised, PAT-A© was feasible to deliver in the NHS and the trial methods and materials were acceptable. Our findings indicate that a fully powered clinical and cost-effectiveness trial of PAT-A© is warranted.

The Mediating Effects of Alexithymia, Intolerance of Uncertainty, and Anxiety on the Relationship Between Sensory Processing Differences and Restricted and Repetitive Behaviours in Autistic Adults / Heather L. MOORE in Journal of Autism and Developmental Disorders, 52-10 (October 2022)

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