In the context of infants showing early signs of autism, we investigated prospective bidirectional associations with 6-min free-play interaction samples collected for 103 caregivers and their infants (mean age 12-months; and followed up 6-months later). We anticipated that measures of caregiver sensitivity/language input and infant language would show within-domain temporal stability/continuity, but also that there would be predictive associations from earlier caregiver input to subsequent child language, and vice versa. Caregiver sensitive responsiveness (from the Manchester Assessment of Caregiver-Infant interaction [MACI]) predicted subsequent infant word tokens (i.e., amount of language, coded following the Systematic Analysis of Language Transcripts [SALT]). Further, earlier infant Mean Length of Utterance (MLU; reflecting language complexity, also derived from SALT coding) predicted later caregiver MLU, even when controlling for variability in infant ages and clear within-domain temporal stability/continuity in key measures (i.e., caregiver sensitive responsiveness and infant word tokens; and infant and caregiver MLU). These data add empirical support to theorization on how caregiver input can be both supportive of, and potentially influenced by, infant capacities, when infants have social-communication differences and/or communication/language delays suggestive of possible emerging autism.

Continuity of temperament subgroup classifications from infancy to toddlerhood in the context of early autism traits / Lacey CHETCUTI in Autism Research, 16-3 (March 2023)  

Public ISBD [article]  inAutism Research > 16-3 (March 2023) . - p.591-604 Titre : Continuity of temperament subgroup classifications from infancy to toddlerhood in the context of early autism traits Type de document : Texte imprimé et/ou numérique Auteurs : Lacey CHETCUTI, Auteur ; Mirko ULJAREVI?, Auteur ; Kandice J. VARCIN, Auteur ; Maryam BOUTRUS, Auteur ; Stefanie DIMOV, Auteur ; Sarah PILLAR, Auteur ; Josephine BARBARO, Auteur ; Cheryl DISSANAYAKE, Auteur ; Jonathan GREEN, Auteur ; Andrew J. O. WHITEHOUSE, Auteur ; Kristelle HUDRY, Auteur ; the AICES TEAM, Auteur Article en page(s) : p.591-604 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Our previous cross-sectional investigation (Chetcuti et al., 2020) showed that infants with autism traits could be divided into distinct subgroups based on temperament. 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.
