SISK, Auteur Article en page(s) : p.2288-2301 Mots-clés : adversity controllability dimensional predictability stress trauma-related symptomatology traumatic stress Index. décimale : PER Périodiques Résumé : Key theoretical frameworks have proposed that examining the impact of exposure to specific dimensions of stress at specific developmental periods is likely to yield important insight into processes of risk and resilience. Utilizing a sample of N = 549 young adults who provided a detailed retrospective history of their lifetime exposure to numerous dimensions of traumatic stress and ratings of their current trauma-related symptomatology via completion of an online survey, here we test whether an individual?s perception of their lifetime stress as either controllable or predictable buffered the impact of exposure on trauma-related symptomatology assessed in adulthood. Further, we tested whether this moderation effect differed when evaluated in the context of early childhood, middle childhood, adolescence, and young adulthood stress. Consistent with hypotheses, results highlight both stressor controllability and stressor predictability as buffering the impact of traumatic stress exposure on trauma-related symptomatology and suggest that the potency of this buffering effect varies across unique developmental periods. Leveraging dimensional ratings of lifetime stress exposure to probe heterogeneity in outcomes following stress ? and, critically, considering interactions between dimensions of exposure and the developmental period when stress occurred ? is likely to yield increased understanding of risk and resilience following traumatic stress.

Thus, characterizing specific behavioral manifestations of temper loss along a dimension from normative misbehaviors to clinically significant problems is an important step toward identifying clinical thresholds. Methods: Parent-reported patterns of temper loss were delineated in a diverse community sample of preschoolers (n = 1,490). A developmentally sensitive questionnaire, the Multidimensional Assessment of Preschool Disruptive Behavior (MAP-DB), was used to assess temper loss in terms of tantrum features and anger regulation. Specific aims were: (a) document the normative distribution of temper loss in preschoolers from normative misbehaviors to clinically concerning temper loss behaviors, and test for sociodemographic differences; (b) use Item Response Theory (IRT) to model a Temper Loss dimension; and (c) examine associations of temper loss and concurrent emotional and behavioral problems. Results: Across sociodemographic subgroups, a unidimensional Temper Loss model fit the data well. Nearly all (83.7%) preschoolers had tantrums sometimes but only 8.6% had daily tantrums. Normative misbehaviors occurred more frequently than clinically concerning temper loss behaviors. Milder behaviors tended to reflect frustration in expectable contexts, whereas clinically concerning problem indicators were unpredictable, prolonged, and/or destructive. In multivariate models, Temper Loss was associated with emotional and behavioral problems. Conclusions: Parent reports on a developmentally informed questionnaire, administered to a large and diverse sample, distinguished normative and problematic manifestations of preschool temper loss. A developmental, dimensional approach shows promise for elucidating the boundaries between normative early childhood temper loss and emergent psychopathology.

Titre : Similar overall expression, but different profiles, of autistic traits, sensory processing, and mental health between young adult males and females Type de document : Texte imprimé et/ou numérique Auteurs : Miranda MCQUARRIE, Auteur ; Savanah CALTON, Auteur ; Terisa P. GABRIELSEN, Auteur Article en page(s) : 102263 Langues : Anglais (eng) Mots-clés : Autism Autistic traits Sensory processing Camouflaging Intolerance of uncertainty Anxiety Female Dimensional Index. décimale : PER Périodiques Résumé : Recent trends suggest that autism is more common in females than traditionally held. Additionally, some argue that females express autistic traits differently than males. Dimensional views of autism could shed light on these issues, especially with regards to understudied behavioral areas, such as sensory processing. We examined autistic traits, sensory processing, anxiety, and related behaviors in a large sample of neurotypical young adult males and females (n = 1122; 556 female; ages 19-26). Participants completed an online survey containing questionnaires related to the above. Between groups statistical analyses, as well as within groups correlations and mediation analyses containing these constructs were then computed. We also carried out a cluster analysis to establish groups with behavioral similarities and estimate within-cluster male/female ratios. Results showed modest differences in the overall expression of autistic traits and sensory processing, if any, between males and females. Conversely, more detailed examination of survey subtests and mediation analyses revealed differing profiles between these groups. Cluster analysis uncovered a group comprised of both males (69.8%) and females (30.2%) who exhibited elevated degrees of autism-related behaviors, suggesting a higher proportion of females than would be predicted by traditional ratios. Taken together, these findings suggest that males and females may not differ as much as previously thought in their general levels of autistic traits or sensory processing, but may present with distinct profiles of such behaviors. These novel results add to our understanding of autistic traits in females and have the potential to positively influence diagnostic and support practices.

Titre : Autistic traits and individual brain differences: functional network efficiency reflects attentional and social impairments, structural nodal efficiencies index systemising and theory-of-mind skills Type de document : Texte imprimé et/ou numérique Auteurs : Subhadip PAUL, Auteur ; Aditi ARORA, Auteur ; Rashi MIDHA, Auteur ; Dinh VU, Auteur ; Prasun K. ROY, Auteur ; Matthew K. BELMONTE, Auteur Article en page(s) : 3p. Langues : Anglais (eng) Mots-clés : Attention Autism Dti Dimensional Functional connectivity Graph theory Social Theory-of-mind fMRI Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism is characterised not only by impaired social cognitive 'empathising' but also by superior rule-based 'systemising'. These cognitive domains intertwine within the categorical diagnosis of autism, yet behavioural genetics suggest largely independent heritability, and separable brain mechanisms. We sought to determine whether quantitative behavioural measures of autistic traits are dimensionally associated with structural and functional brain network integrity, and whether brain bases of autistic traits vary independently across individuals. METHODS: Thirty right-handed neurotypical adults (12 females) were administered psychometric (Social Responsiveness Scale, Autism Spectrum Quotient and Systemising Quotient) and behavioural (Attention Network Test and theory-of-mind reaction time) measures of autistic traits, and structurally (diffusion tensor imaging) and functionally (500 s of 2 Hz eyes-closed resting fMRI) derived graph-theoretic measures of efficiency of information integration were computed throughout the brain and within subregions. RESULTS: Social impairment was positively associated with functional efficiency (r = .47, p = .006), globally and within temporo-parietal and prefrontal cortices. Delayed orienting of attention likewise was associated with greater functional efficiency (r = - .46, p = .0133). Systemising was positively associated with global structural efficiency (r = .38, p = 0.018), driven specifically by temporal pole; theory-of-mind reaction time was related to structural efficiency (r = - .40, p = 0.0153) within right supramarginal gyrus. LIMITATIONS: Interpretation of these relationships is complicated by the many senses of the term 'connectivity', including functional, structural and computational; by the approximation inherent in group functional anatomical parcellations when confronted with individual variation in functional anatomy; and by the validity, sensitivity and specificity of the several survey and experimental behavioural measures applied as correlates of brain structure and function. CONCLUSIONS: Functional connectivities highlight distributed networks associated with domain-general properties such as attentional orienting and social cognition broadly, associating more impaired behaviour with more efficient brain networks that may reflect heightened feedforward information flow subserving autistic strengths and deficits alike. Structural connectivity results highlight specific anatomical nodes of convergence, reflecting cognitive and neuroanatomical independence of systemising and theory-of-mind. In addition, this work shows that individual differences in theory-of-mind related to brain structure can be measured behaviourally, and offers neuroanatomical evidence to pin down the slippery construct of 'systemising' as the capacity to construct invariant contextual associations.
