Sahib A, Chen J, Cárdenas D, Calear AL, Wilson C. Emotion regulation mediates the relation between intolerance of uncertainty and emotion difficulties: A longitudinal investigation.

Abstract
Intolerance of uncertainty has been proposed as a transdiagnostic factor in emotional disorders. Despite comprehensive empirical evidence demonstrating the association between intolerance of uncertainty and emotional disorders, the underlying mechanism remains elusive. Drawing on theoretical frameworks and empirical studies, the current study proposed that emotion regulation emerges as a potential mechanism. We explored the connections among intolerance of uncertainty, eight emotion regulation strategies (both adaptive and maladaptive), and emotional difficulties (specifically anxiety and depression) using a three-wave longitudinal approach (N = 341). Our findings revealed that heightened intolerance of uncertainty predicted increased anxiety but not depression over time. Greater intolerance of uncertainty significantly predicted elevated levels of maladaptive emotion regulation strategies including experiential avoidance, thought suppression, rumination, and reassurance-seeking. Adaptive strategies (i.e., mindfulness, cognitive reappraisal, problem-solving) predicted lower anxiety and/or depression whereas maladaptive emotion regulation strategy rumination predicted greater levels of anxiety and depression. Surprisingly, thought suppression predicted lower levels of anxiety and depression. More importantly, our analysis showed that both rumination and thought suppression served as significant mediators in the relationship between intolerance of uncertainty and both anxiety and depression. These results hold implications for future interventions, emphasising rumination and thought suppression as potential targets for interventions aimed at alleviating emotional difficulties in individuals with intolerance of uncertainty.

Characterising Insistence on Sameness and Circumscribed Interests: A Qualitative Study of Parent Perspectives. J Autism Dev Disord 2024:10.1007/s10803-024-06404-4. [PMID: 38809473 DOI: 10.1007/s10803-024-06404-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/10/2024] [Indexed: 05/30/2024]
Abstract
Manifestations of insistence on sameness (IS) and circumscribed interests (CI) are complex, with individuals varying considerably, not only in the types of behaviours they express, but also in terms of a behaviour's frequency, intensity, trajectory, adaptive benefits, and impacts. However, current quantitative RRB instruments capture only certain aspects of these behaviours (e.g., mostly frequency or general "severity"). Thus, the current study utilised a semi-structured caregiver interview to provide an in-depth, qualitative characterization of different aspects of IS and CI presentation. Caregivers of 27 autistic children and adolescents displaying IS and/or CI behaviours (3-16 years; 18 males; 9 females) participated in a semi-structured interview. Responses were analysed using thematic framework analysis. Framework analysis identified nine different aspects of IS and CI presentation: (1) intensity, (2) frequency, (3) emergence of behaviour, (4) changes over time, (5) day-to-day fluctuations, (6) purpose/adaptive benefit, (7) experiences of distress, (8) challenges for the individual, their family, and their socialisation, and (9) management strategies and their effectiveness. Autistic children and adolescents were reported to vary greatly on each of these dimensions. Findings demonstrate the complexity of IS and CI presentations and highlight the need for more comprehensive quantitative assessments that independently assess the frequency, intensity, and impact of behaviours. Further, findings reported here emphasize the need for ecologically valid measures that assess the contexts in which these behaviours occur and how their presentations can change within and across days.

Abstract
The Anxiety Scale for Autism-Adults (ASA-A) captures the autistic anxiety experience, but we do not know whether it is structurally equivalent for men and women, or non-autistic people. Measurement invariance analysis considered gender and diagnostic status (342 cis-gender autistic men (N = 105) and women (N = 237), 316 cis-gender non-autistic men (N = 104) and women (N = 212)). Strict invariance was achieved between autistic men and women and between non-autistic men and women, but the ASA-A structure is quantitatively different in autistic compared to non-autistic adults. Therefore, this tool cannot be used to directly compare anxiety between these groups. Autistic women scored significantly higher on the ASA-A than autistic men and Uncertainty was the highest scoring factor for autistic participants. Future research should include alternative gender identities.

Abstract
Autistic children are at increased risk of experiencing a range of mental health difficulties, including anxiety. A number of intervention programmes are now available in high-income countries to support autistic children. However, to date there are no evidence-based interventions to support families of such children in South Asia. Based on consultations with clinicians, researchers and parents in Bangladesh and Sri Lanka, we developed a culturally tailored two-session skills-based group programme for parents whose autistic children present with anxiety. This paper describes the process of creating this programme, to be delivered by mental health professionals.

Abstract
Previous research has indicated that autistic individuals report lower quality of life (QoL) than non-autistic people. It is unclear whether it is the autism traits themselves or co-occurring thinking styles or mental health difficulties that most impair QoL. This study tested a hypothesised model to explore how 'intolerance of uncertainty' (IU), alexithymia (difficulty in identifying and describing own emotions), and anxiety play into the association between autistic traits and QoL. Online survey data were analysed from 116 autistic and 51 non-autistic adults who completed six standardised questionnaires measuring autistic traits, alexithymia, IU, anxiety and QoL (physical health, psychological health, social relations, and environment domains). The autistic group reported higher scores for alexithymia, IU and anxiety, and lower scores for QoL across domains, compared to the non-autistic group. Across the entire sample, autistic traits, alexithymia, IU and anxiety were positively correlated with one another, and negatively related to the four domains of QoL. Finally, IU and anxiety partially serially mediated the pathways from autistic traits to physical health and environment domains of QoL, and fully mediated the pathways from autistic traits to psychological health and social relations domains of QoL, across the full sample. The lower QoL experienced by autistic people may be explained in part by the mediating effect of both IU and anxiety (but not alexithymia). This study highlights the need for evidence-based interventions to address both IU and anxiety to improve QoL for autistic people/those with high levels of autistic traits.

Abstract
OBJECTIVE Anxiety is prevalent in young autistic children under 7 years of age. Yet there is a paucity of empirically based interventions for this age group. DINO Strategies for Anxiety and Uncertainty Reduction (DINOSAUR) is an innovative cognitive behavioral intervention that seeks to optimize treatment response in young autistic children by targeting anxiety and the contributing mechanisms of intolerance of uncertainty and parental accommodation using a telehealth delivery model. This pilot, single-arm study examines the preliminary feasibility of DINOSAUR. METHODS Fourteen autistic children ages 4-6 years with average language and cognitive skills and their parents received the intervention. Quantitative and qualitative data pertaining to parent satisfaction and treatment outcomes were collected. RESULTS Attendance, retention, and parent satisfaction ratings offer preliminary support for the feasibility of the treatment model. Change in clinical severity ratings on a semi-structured parent interview of anxiety and parents' qualitative report suggests the potential to benefit young autistic children. CONCLUSIONS Results support future study of the DINOSAUR model in a larger, randomized controlled trial.

Abstract
Mental health difficulties commonly co-occur with autism, especially in autistic people accessing clinic services, impacting substantially on quality-of-life. Alexithymia (difficulty describing/identifying feelings) and sensory processing differences are prevalent traits in autism that have been associated with depression/anxiety in autistic community samples. However, it is important to better understand interrelationships between these traits in clinical populations to improve identification of service-user needs. In this study, 190 autistic adults (65.3% male), seen in a tertiary autism clinic, completed self-report measures of alexithymia (20-item Toronto Alexithymia Scale), sensory processing differences (Adolescent/Adult Sensory Profile) and depression/anxiety (Hospital Anxiety and Depression Scale). Multiple linear regression models and mediation analyses were used to examine associations between alexithymia, sensory processing differences, and depression/anxiety severity. Across the sample, 66.3% of individuals (N = 126) were classified as alexithymic (score ≥ 61). Total alexithymia and difficulty describing/identifying feelings were significantly associated with depression severity (β = 0.30-0.38, highest p < 0.002), and difficulty identifying feelings was significantly associated with anxiety severity (β = 0.36, p < 0.001). Sensory processing differences were also significantly associated with depression severity (β = 0.29, p = 0.002) and anxiety severity across all models (β = 0.34-0.48, highest p < 0.001) Finally, difficulty describing/identifying feelings partially mediated the relationships between sensory processing differences and both depression/anxiety severity. Overall, these results highlight that interventions adapted for and targeting emotional awareness and sensory-related uncertainty may improve mental health outcomes in autistic service-users.

Abstract
Purpose of Review Elevated prevalence of autism characteristics is reported in genetic syndromes associated with intellectual disability. This review summarises recent evidence on the behavioural heterogeneity of autism in the following syndromes: Fragile X, Cornelia de Lange, Williams, Prader-Willi, Angelman, Down, Smith-Magenis, and tuberous sclerosis complex. Key considerations for assessment and support are discussed. Recent Findings The profile and developmental trajectory of autism-related behaviour in these syndromes indicate some degree of syndrome specificity which may interact with broader behavioural phenotypes (e.g. hypersociability), intellectual disability, and mental health (e.g. anxiety). Genetic subtype and co-occurring epilepsy within syndromes contribute to increased significance of autism characteristics. Autism-related strengths and challenges are likely to be overlooked or misunderstood using existing screening/diagnostic tools and criteria, which lack sensitivity and specificity within these populations. Summary Autism characteristics are highly heterogeneous across genetic syndromes and often distinguishable from non-syndromic autism. Autism diagnostic assessment practices in this population should be tailored to specific syndromes. Service provisions must begin to prioritise needs-led support.
