Assessing Restricted and Repetitive Behaviours in Online-Sampled Autistic and Non-autistic Individuals: Factor Structure of the Repetitive Behaviours Questionnaire for Adults (RBQ-2A) / Jack D. BRETT in Journal of Autism and Developmental Disorders, 54-6 (June 2024)

MAYBERY, Auteur Article en page(s) : p.2138-2147 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The Repetitive Behaviours Questionnaire for Adults (RBQ-2A) measures two factors of restricted and repetitive behaviours (RRBs) associated with autism. However, the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) provides four criteria for RRBs: repetitive motor behaviours, insistence on sameness, restricted interests, and interest in sensory aspects of the environment (or atypical sensitivity). The current paper aimed to examine whether the RBQ-2A is a psychometrically sound measure of these four factors. Study 1 had university students (N = 368) complete the RBQ-2A and other related measures online and revealed that the RBQ-2A can assess the factors highlighted in the DSM-5 and that these four factors comprise a general RRB construct. Study 2 had individuals disclosing a diagnosis of autism (N = 283) complete the RBQ-2A and other related measures online and supported that this four-factor structure provided good psychometric properties. While the current paper provides findings for an online autistic population, further research is needed to generalize these findings to autistic individuals less likely to partake in online studies (e.g., those with intellectual or language disabilities). Overall, the results suggest that the RBQ-2A reliably and validly assesses RRBs.

Measuring autistic burnout: A psychometric validation of the AASPIRE Autistic Burnout Measure in autistic adults / Mackenzie BOUGOURE in Autism, 30-1 (January 2026)

BRETT, Auteur ; Murray T. MAYBERY, Auteur ; Michael C. ENGLISH, Auteur ; Diana Weiting TAN, Auteur ; Iliana MAGIATI, Auteur Article en page(s) : p.20-36 Langues : Anglais (eng) Mots-clés : autism  burnout  measurement  psychometric properties  reliability  validity Index. décimale : PER Périodiques Résumé : Autistic burnout is characterised by extreme exhaustion, loss of functioning, and reduced tolerance to stimulus, resulting from the cumulative stress associated with navigating a predominantly non-autistic world. To date, in mostly qualitative studies, autistic burnout has been associated with poorer mental health, well-being and life outcomes in autistic adults. To comprehensively investigate autistic burnout, identify affected individuals and evaluate supports, a valid and reliable measure is required. The current study explored the psychometric properties of the AASPIRE Autistic Burnout Measure. The Autistic Burnout Measure and other related measures (camouflaging, mental health) were completed online by 379 autistic adults. The Autistic Burnout Measure demonstrated a predominantly unidimensional structure, with high loadings across all 27 items, excellent internal consistency (ω = 0.98), and reasonable consistency over 12 months (r = 0.59). It also showed sound construct validity, with medium-to-large positive correlations with autistic traits, camouflaging, occupational burnout, depression and anxiety. The Autistic Burnout Measure also effectively differentiated between autistic participants who reported currently experiencing autistic burnout and those who were not (area under the curve = 0.92; 95% confidence interval = [0.86, 0.97]). Our findings indicate that the Autistic Burnout Measure has promising psychometric properties and may be a useful measure in future autism research and practice. However, further validation is necessary to determine whether the unidimensional structure holds across diverse samples.Lay abstract Autistic people have described autistic burnout as an intense experience of physical, emotional, mental and social exhaustion impacting their ability to complete everyday tasks and contributing to poorer well-being. To identify and measure autistic burnout in practice and research, we need a self-report measure that gives accurate and consistent results. In this study, 379 autistic adults completed a recently developed measure of autistic burnout online, the AASPIRE Autistic Burnout Measure. We analysed their ratings to determine whether the measure is reliable (i.e. ratings are consistent), valid (i.e. the tool measures what it says it measures), correctly identifies those currently experiencing burnout, and is associated with other relevant experiences, such as camouflaging, anxiety and depression. The Autistic Burnout Measure was found to be reliable and valid. Autistic adults reporting greater autistic burnout also reported more camouflaging, autistic traits and greater general burnout, depression, and anxiety. The Autistic Burnout Measure was accurate in identifying individuals who reported currently experiencing autistic burnout and those who did not. Overall, our findings suggest that the Autistic Burnout Measure may be suitable for use in research and practice to identify and better understand experiences of autistic burnout.

Understanding Oneself to Understand Others: The Role of Alexithymia and Anxiety in the Relationships Between Autistic Trait Dimensions and Empathy / Jack D. BRETT in Journal of Autism and Developmental Disorders, 52-5 (May 2022)

The present study examined independent autistic trait dimensions (social difficulties and restricted/repetitive behaviours) and the roles alexithymia and trait anxiety have in explaining this profile of empathy. Results from the general population (n=301) revealed that pronounced social difficulties and not restricted/repetitive behaviours related to reduced cognitive and affective empathy, and heightened personal distress. However, both dimensions, through alexithymia and anxiety, indirectly influenced empathy. Surprisingly, while the dimensions indirectly improved affective empathy, pronounced social difficulties directly reduced affective empathy. This study motivates a nuanced model of empathy by including autistic trait dimensions, anxiety, and alexithymia.
