This longitudinal study builds on this existing work by exploring the continuity of temperament subgroup classifications and their associations with behavioral/clinical phenotypic features from infancy to toddlerhood. 103 infants (68% male) showing early signs of autism were referred to the study by community healthcare professionals and seen for assessments when aged around 12-months (Time 1), 18-months (Time 2), and 24-months (Time 3). Latent profile analysis revealed inhibited/low positive, active/negative reactive, and sociable/well-regulated subgroups at each timepoint, and a unique reactive/regulated subgroup at Time 3. Cross-tabulations indicated a significant likelihood of children having a recurrent subgroup classification from one timepoint to the next, and no apparent patterns to the movement of children who did change from one subgroup to another over time. Temperament subgroups were associated with concurrent child social-emotional functioning and autism traits, but unrelated to child age, sex, or developmental level. These findings suggest that temperament subgroup classifications might represent a reliable and very early indicator of autism characteristics and social-emotional functioning among infants/toddlers with autism traits.

Performance of the Autism Observation Scale for Infants with community-ascertained infants showing early signs of autism / Kristelle HUDRY in Autism, 25-2 (February 2021)  

Public ISBD [article]  inAutism > 25-2 (February 2021) . - p.490-501 Titre : Performance of the Autism Observation Scale for Infants with community-ascertained infants showing early signs of autism Type de document : Texte imprimé et/ou numérique Auteurs : Kristelle HUDRY, Auteur ; Lacey CHETCUTI, Auteur ; Maryam BOUTRUS, Auteur ; Sarah PILLAR, Auteur ; Emma K. BAKER, Auteur ; Stefanie DIMOV, Auteur ; Josephine BARBARO, Auteur ; Jonathan GREEN, Auteur ; Andrew J. O. WHITEHOUSE, Auteur ; Kandice J. VARCIN, Auteur Article en page(s) : p.490-501 Langues : Anglais (eng) Mots-clés : developmental psychology  diagnosis  early signs  individual variability/heterogeneity  infants  psychometrics Index. décimale : PER Périodiques Résumé : We investigated whether a commonly used research assessment - the Autism Observation Scale for Infants (AOSI) - accurately measures autism behaviours among infants showing early signs of autism identified within the community. The AOSI is often included in studies tracking the development of infants at increased likelihood of autism, such as the infant siblings of diagnosed children. However, the suitability of this measure has not previously been tested with community-referred infants. We administered the AOSI with infants when aged 9 to 14 months and again 6?months later. Our researchers - independent of the AOSI development team and newly trained on this measure - were able to administer the brief interactive assessment and score it accurately. The infants' AOSI scores were linked to their scores on other established and validated clinical assessments, particularly at the second visit when average age was 18?months. Stronger correspondence of AOSI and other scores at this second visit suggests early autism behaviours are better established and more consistent by 18?months of age, even though these infants showed clear enough signs of possible autism to prompt referral to our study around 12?months of age. However, the moderate association of AOSI scores over time suggests that, like infant siblings - who mostly do not develop autism - community-identified infants showing early signs may also have variable developmental pathways in early life.
