The MacArthur-Bates Communicative Development Inventory was administered monthly from 8 to 14 months and at 18 and 24 months to caregivers of 14 HR infants diagnosed with ASD (HR-ASD), 27 HR infants with language delay (HR-LD), 51 HR infants with no diagnosis (HR-ND), and 28 LR infants. Few differences were obtained between LR and HR-ND infants, but HR-LD and HR-ASD groups differed in initial skill levels and growth patterns. While HR-LD infants grew at rates comparable to LR and HR-ND infants, growth was attenuated in the HR-ASD group, with trajectories progressively diverging from all other groups.

Observed Social Emotional Behavior at 22 Months Predicts a Later ASD Diagnosis in High-Risk Siblings / Jessie B. NORTHRUP in Journal of Autism and Developmental Disorders, 51-9 (September 2021)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 51-9 (September 2021) . - p.3187-3198 Titre : Observed Social Emotional Behavior at 22 Months Predicts a Later ASD Diagnosis in High-Risk Siblings Type de document : Texte imprimé et/ou numérique Auteurs : Jessie B. NORTHRUP, Auteur ; N. B. LEEZENBAUM, Auteur ; S. B. CAMPBELL, Auteur Article en page(s) : p.3187-3198 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/diagnosis  Child, Preschool  Emotions  Empathy  Humans  Siblings  Social Behavior  Autism spectrum disorder  Empathic concern  High-risk siblings  Pretend play  Social engagement Index. décimale : PER Périodiques Résumé : Social engagement, pretend play, and concern for another's distress represent fundamental features of typical social-emotional development in the second year. Children with autism spectrum disorder (ASD) display delays and deficits in these areas, and research on toddlers at heightened risk for ASD (HR; younger siblings of children with ASD) indicates these deficits may be apparent in toddlerhood. Prior research has examined these aspects of social-emotional development individually in HR toddlers. The present paper examines them jointly as predictors of ASD. We show that social engagement, pretend play, and empathic concern at 22-months each contribute uniquely to predicting later ASD diagnosis with high specificity and moderate sensitivity. Results have important implications for early diagnosis and intervention in young children with ASD.

Trajectories of Posture Development in Infants With and Without Familial Risk for Autism Spectrum Disorder / N. B. LEEZENBAUM in Journal of Autism and Developmental Disorders, 49-8 (August 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-8 (August 2019) . - p.3257-3277 Titre : Trajectories of Posture Development in Infants With and Without Familial Risk for Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : N. B. LEEZENBAUM, Auteur ; J. M. IVERSON, Auteur Article en page(s) : p.3257-3277 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Infant siblings  Motor development  Posture Index. décimale : PER Périodiques Résumé : This study investigated early posture development prospectively in infants at heightened (HR) vs. low risk (Low Risk; LR) for ASD. Fourteen HR infants diagnosed with ASD (HR-ASD), 17 HR infants with language delay (HR-LD), 29 HR infants with no diagnosis (HR-ND), and 25 LR infants were videotaped at home for 25 min during everyday activities and play at 6, 8, 10, 12, and 14 months. All postures were coded and the sustainment source was identified for supported postures. Relative to LR infants, HR-ASD infants and to a lesser extent HR-LD infants exhibited distinct postural trajectories that revealed slower development of more advanced postures. In addition, subtle differences in posture sustainment differentiated HR-ASD from HR-LD infants.
