Sensory hyperreactivity may predict both anxiety and intolerance of uncertainty, and anxiety and intolerance of uncertainty may both be mutually important, mediating factors. These findings have implications for early anxiety interventions. But there is a pressing need for objective assessments that can be used with preschool-age autistic children.

Research shows that this may be related to intolerance of uncertainty, which is a tendency to react negatively to uncertain situations. Understanding when, why and how autistic children respond to uncertainty is important in the development of anxiety programmes. We asked 53 (including 3 dyads) parents of autistic children about the types of uncertain situations that cause difficulties for their child and how uncertainty impacts on daily life for them and their families. We found that uncertain situations made autistic children and their families feel sad, worried, frustrated and angry through the themes: child's reactions to uncertainty, trying to reduce uncertainty, the impact of difficulties with uncertainty, the impact of uncertainty on parenting and the impact on parents. There are lots of situations that are anxiety provoking for autistic children because of uncertainty, such as school. Programmes to reduce anxiety and increase autistic children's ability to cope with everyday uncertain situations could improve quality of life for autistic children and their families.

Exploring Alexithymia, Uncertainty, Anxious Arousal, and Social Anxiety as Mediators of the Relationship Between Sensory Processing Differences and Restricted and Repetitive Behaviors in Autistic Adults / Heather L. MOORE in Autism Research, 19-2 (February 2026)  

Public ISBD [article]  inAutism Research > 19-2 (February 2026) . - e70145 Titre : Exploring Alexithymia, Uncertainty, Anxious Arousal, and Social Anxiety as Mediators of the Relationship Between Sensory Processing Differences and Restricted and Repetitive Behaviors in Autistic Adults Type de document : texte imprimé Auteurs : Heather L.

PARR, Auteur ; Jacqui RODGERS, Auteur Article en page(s) : e70145 Langues : Anglais (eng) Mots-clés : alexithymia  anxious arousal  autism  restricted and repetitive behaviors  sensory processing  social anxiety  uncertainty Index. décimale : PER Périodiques Résumé : ABSTRACT Restricted and repetitive behaviors (RRB) are associated with sensory processing (SP) differences for autistic people, and are thought to be a coping strategy to help manage the sensory environment. 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.

Intolerance-of-uncertainty and anxiety as serial mediators between emotional dysregulation and repetitive patterns in young people with autism / Carmen BENEYTEZ in Research in Autism Spectrum Disorders, 102 (April 2023)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 102 (April 2023) . - p.102116 Titre : Intolerance-of-uncertainty and anxiety as serial mediators between emotional dysregulation and repetitive patterns in young people with autism Type de document : texte imprimé Auteurs : Carmen BENEYTEZ, Auteur Article en page(s) : p.102116 Langues : Anglais (eng) Mots-clés : Anxiety  Transdiagnostic factors  Repetitive and restricted patterns  Emotional well-being  Emotional dysregulation  Uncertainty Index. décimale : PER Périodiques Résumé : Background Previous research on anxiety in autism has largely focused on direct relationships. The overlap between symptoms of autism and anxiety and the influence that transdiagnostic variables exert on them make necessary explanatory models that consider all the factors involved in the triggering and maintenance of anxiety and its expression through typical features of autism. Method The main objective of this study was to examine the relationship between two transdiagnostic mechanisms (emotional dysregulation (ED) and intolerance of uncertainty (IU)) and repetitive and restricted patterns (RRP) and the role that anxiety has in this relationship. IU and anxiety were configured as serial mediators between ED and two subtypes of restricted patterns: sameness behaviors and sensory over-responsiveness. The sample included 87 children and adolescents on the autism spectrum aged from 6 to 18 years. Variables were assessed using a number of well-known outcome measures. Results The results of our simple mediation model show that the indirect effect of anxiety is higher between transdiagnostic variables and sensory over-responsiveness than between transdiagnostic variables and sameness behaviors. Our model suggests that ED predicts sameness behaviors and sensory over-responsiveness through the serial indirect effect of IU and anxiety. Conclusions Our findings contribute to clarify the role that anxiety and transdiagnostic mechanisms may play on RRP and may have important implications for the assessment and treatment of anxiety in people with ASD.

"Intolerance of uncertainty" mediates the relationship between social profile and anxiety in both Williams syndrome and autism / Mikle SOUTH in Autism Research, 14-9 (September 2021)  

Public ISBD [article]  inAutism Research > 14-9 (September 2021) . - p.1986-1995 Titre : "Intolerance of uncertainty" mediates the relationship between social profile and anxiety in both Williams syndrome and autism Type de document : texte imprimé Auteurs : Mikle SOUTH, Auteur ; Mary HANLEY, Auteur ; Karys NORMANSELL-MOSSA, Auteur ; Nicholas C.C. RUSSELL, Auteur ; Thomas CAWTHORNE, Auteur ; Deborah M. RIBY, Auteur Article en page(s) : p.1986-1995 Langues : Anglais (eng) Mots-clés : Adolescent  Adult  Anxiety/complications  Autism Spectrum Disorder/complications  Autistic Disorder/complications  Child  Child, Preschool  Cross-Sectional Studies  Humans  Uncertainty  Williams Syndrome/complications  Young Adult  Intolerance of Uncertainty  Williams syndrome  anxiety  autism  children  social function  social profile Index. décimale : PER Périodiques Résumé : Anxiety is the most significant mental health concern for both Williams syndrome (WS) and autism. Whilst WS and autism are characterized by some syndrome-specific social differences, less is known about cross-syndrome profiles of anxiety symptoms. Previous research has shown that Intolerance of Uncertainty (IU) is a core mechanism of anxiety maintenance for clinically anxious populations and for autistic children, adolescents, and adults. The only published study in this area for WS has shown some similar patterns-with an added emphasis on the role of sensory sensitivities-in a sample of older teens and adults (mean age = 24), with the authors highlighting the need for younger samples to consider developmental influences. Here we report a cross-syndrome, cross-sectional mediation analyses of children diagnosed with WS or autism, including data from parent surveys of 90 children with WS (n = 48) or autism (n = 42). Group differences showed higher trait levels on all measures for the autism group. Importantly, the relationship between social profile and anxiety was fully mediated by IU level for both groups. This suggests possible similar core mechanisms underlying anxiety in these conditions, and the possibility of generalized intervention approaches especially related to managing distress related to uncertainty in multiple contexts. LAY SUMMARY: Autism and Williams Syndrome share some similarities in social profile and also in anxiety traits, but there are also some key differences as well. Comparing them side-by-side at the same time improved identification of ways to reduce feelings of anxiety. We found that the intolerance of uncertainty affected the relationship between social profile and anxiety in the same way for young children diagnosed with autism or Williams syndrome, meaning that intervention approaches could be similar for both.
