BARANEK, Auteur Article en page(s) : 102035 Langues : Anglais (eng) Mots-clés : Autism  Eye-tracking  Non-social attention  Sensory features Index. décimale : PER Périodiques Résumé : Background Aberrant attention patterns have been commonly reported in autistic children. However, few studies have examined attention to non-social stimuli varying in salience and complexity using eye-tracking technology, as well as their links to clinical sensory features. Method Forty-one children [16 with autism spectrum disorder (ASD), 10 with developmental delay (DD), and 15 neurotypical (NT)] ages 4 to 13 years were included in this cross-sectional study. Children completed a passive-viewing eye-tracking task designed to measure visual attention (e.g., fixation duration and count) to non-social stimuli with sensory qualities involving motion (spinning or non-spinning) and sound. Parents completed a clinical questionnaire about their child’s sensory behaviors. Eye-tracking metrics were compared across stimulus conditions and diagnostic groups, and their associations with parent-report sensory features were examined. Results Overall children showed longer fixation durations and fewer fixation counts to more complex stimuli (e.g., moving or spinning objects), but such facilitatory effects of stimulus properties tended to be less evident in DD versus ASD or NT groups. More clinical sensory features, especially hyperresponsiveness, were moderately to highly associated with quicker initial fixations and longer fixation durations across stimulus conditions in ASD, but not in DD and NT groups. Conclusion The overall attention and initial orientation to non-social stimuli were comparable across autistic children and their non-autistic peers, with some sensory properties such as dynamic motion producing a facilitatory effect (i.e., fewer fixations of longer durations) on attention. However, sensory differences, particularly hyperresponsiveness, might underlie attention patterns as impacted by stimulus properties specifically in autism.

Early developmental profiles of sensory features and links to school-age adaptive and maladaptive outcomes: A birth cohort investigation / Yun-Ju CHEN in Development and Psychopathology, 36-1 (February 2024)

This prospective study aimed to identify subtypes based on trajectories of parent-reported sensory features measured at 6-19 months, 3-4, and 6-7 years of age among a community-based birth cohort (N = 1,517), and to examine their associations with school-age clinical and adaptive/maladaptive outcomes on a subset sample (N = 389). Latent class growth analysis revealed five trajectory subtypes varying in intensity and change rates across three sensory domains. In contrast to an Adaptive-All Improving subtype (35%) with very low sensory features and overall better school-age outcomes, an Elevated-All Worsening subtype (3%), comprised of more boys and children of parents with less education, was associated with most elevated autistic traits and poorest adaptive/maladaptive outcomes. Three other subtypes (62% in total) were generally characterized by stable or improving patterns of sensory features at mild to moderate levels, and challenges in certain outcome domains. Our findings indicate that characterizing children based on early sensory trajectories may contribute to earlier detection of subgroups of children with sensory challenges who are more likely to experience developmental challenges by school age, followed by early targeted interventions for improved long-term outcomes.

Early measurement of autism risk constructs in the general population: A new factor structure of the First Years Inventory (FYIv3.1) for ages 6-16 months / Grace T. BARANEK in Autism Research, 15-5 (May 2022)  

Public ISBD [article]  inAutism Research > 15-5 (May 2022) . - p.915-928 Titre : Early measurement of autism risk constructs in the general population: A new factor structure of the First Years Inventory (FYIv3.1) for ages 6-16 months Type de document : Texte imprimé et/ou numérique Auteurs : Grace T. BARANEK, Auteur ; John SIDERIS, Auteur ; Yun-Ju CHEN, Auteur ; Elizabeth R. CRAIS, Auteur ; Lauren M. TURNER-BROWN, Auteur ; Linda R. WATSON, Auteur Article en page(s) : p.915-928 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/complications/diagnosis/epidemiology  Autistic Disorder/complications/diagnosis/epidemiology  Child  Child, Preschool  Communication  Humans  Infant  Infant Behavior  Parents  autism spectrum disorder  community sample  developmental delay  early identification  infant development  neurodevelopmental risk Index. décimale : PER Périodiques Résumé : Early detection of autism risk in the community is critical to increasing families' access to early intervention, yet few measures have been developed and tested for the general population of infants <16?months to tap a broader range of autism risk constructs. This study aimed to (a) examine the factor structure of the First Years Inventory, version 3.1 (FYIv3.1), with a sample of 6454 infants 6-16?months, and (b) determine the ability of the resulting factors to discriminate clinical outcome groups at 3?years of age. The FYIv3.1 is a parent-report tool designed to detect early behavioral risk signs that may be associated with a later diagnosis of ASD and related neurodevelopmental conditions. Factor analytic models were used to determine the number of constructs and inter-factor correlations. Findings supported a seven-factor structure: communication, imitation and play (CIP); social attention and affective engagement (SAE); sensory hyperresponsiveness (HYPER); sensory hyporesponsiveness (HYPO); self-regulation in daily routines (SREG); sensory interests, repetitions, and seeking behaviors (SIRS); motor coordination and milestones (MCM). Mean comparisons on these factors demonstrated significant discrimination of the three outcome groups at age 3?years including those classified as having an ASD diagnosis and/or high autism symptoms, those classified as having other developmental disorders/conditions/concerns, and those classified with no known conditions/concerns. These findings support the validity and multidimensionality of early ASD risk constructs, as well as the potential use of the FYIv3.1 for phenotypic subtyping in the general population, and early detection in a broader age range of 6-16?months in future clinical studies. LAY SUMMARY: The FYIv3.1 is a 69-item parent-report questionnaire about infant behaviors that may indicate an elevated likelihood for later neurodevelopmental conditions such as autism. Analyses of responses from 6454 parents of infants 6-16 months indicated that items could be grouped reliably into seven categories. Compared to children with or without other developmental conditions, children in the outcome group with autism spectrum disorder and/or high autism symptoms at age three showed more behavioral risk signs in social-communication, sensory, and motor domains during infancy.

Caregiver responsiveness, which has been linked to positive social communication outcomes, has not been adequately examined with regard to infant sensory reactivity. This study examined the multiplicative impact of infant sensory hypo- and hyperreactivity on caregiver responsiveness to sensory reactivity and regulation cues in 43 infants at elevated likelihood of autism. Sensory hyperreactivity was found to moderate the association between sensory hyporeactivity and caregiver responsiveness, such that caregivers of infants with moderately high sensory hypo- and hyperreactivity demonstrated higher responsiveness.

Trajectory research in children with an autism diagnosis: A scoping review / Stephen J. GENTLES in Autism, 28-3 (March 2024)

By assessing developmental or health-related outcome domains at three or more timepoints, trajectory studies can characterize their shape and varying rates of change over time. The purpose of this scoping review was to identify and summarize the published breadth of research that uses a trajectory study design to examine development in children (to age 18?years) diagnosed with autism. Using a systematic search and screening procedure, 103 studies were included. This review summarizes methodological characteristics across studies including the varying statistical approaches used. A series of figures maps where published research is available across 10 outcome domains and the ages over which children have been followed. Evidence gaps, informed by the perspectives of the autistic and caregiver stakeholders that were engaged in this review, are discussed. We recommend that future trajectory research addresses the absence of studies from low- and middle-income countries, considers longitudinal assessment of outcome domains that caregivers and autistic people consider meaningful, and plans follow-up periods with assessment timepoints that cover the gaps in ages where more outcome-specific data are needed. Lay Abstract The types of outcomes studied in children on the autism spectrum include clinical characteristics, such as social functioning, communication, language, or autism symptoms. Research that measures these outcomes at multiple timepoints is useful to improve our understanding of what to expect as children develop. In trajectory studies, researchers assess outcomes at three or more timepoints. This method has advantages over two-timepoint studies because it allows researchers to describe changes in the speed of development, such as accelerations, plateaus, or slowdowns. We identified and reviewed 103 published trajectory studies in children (to age 18?years) with an autism diagnosis. Importantly, we did not include studies of treatments or their effects, nor did we summarize the results of studies. Instead, this review summarizes the characteristics of the available published research, including the methods used, the many different outcomes that have been studied over time and the ages over which they have been studied. This summary may be of interest to autistic people and caregivers (parents) who want to know about the existence of research that provides answers about what to expect during an autistic child?s development. We have recommended that future trajectory research efforts try to make up for the lack of studies from low- and middle-income countries; that more attention is given to the following outcomes that are meaningful to caregivers and autistic people; and to try to fill in the age gaps where more outcome-specific data are needed.
