Longitudinal research on language abilities and social functioning in young children suggests that gains in one domain affect gains in the other. However, few studies have examined inter-relations of language and social functioning jointly among young children diagnosed with autism spectrum disorder (ASD). Pre-verbal toddlers with ASD are a group…

Christopher Lopata; Marcus L. Thomeer; Jonathan D. Rodgers; James P. Donnelly; Jennifer Lodi-Smith – Journal of Autism and Developmental Disorders, 2025
A prior randomized trial found a school social intervention yielded significantly better outcomes (social and autism features) immediately following intervention compared to typical school programming (services-as-usual [SAU]) for children on the autism spectrum. In that study, children in the SAU condition subsequently completed a summer social…

Intelligence (IQ) scores are used in educational and vocational planning for individuals with autism spectrum disorder (ASD) yet little is known about the stability of IQ throughout development. We examined longitudinal age-related IQ stability in 119 individuals with ASD (3-36 years of age at first visit) and 128 typically developing controls.…

Mason, David; Capp, Simone J.; Stewart, Gavin R.; Kempton, Matthew J.; Glaser, Karen; Howlin, Patricia; Happé, Francesca – Journal of Autism and Developmental Disorders, 2021
Longitudinal studies have generally reported poor outcomes in adulthood for the majority of individuals (c.50-60%) with autism. Several factors putatively predict outcome (e.g. IQ), but findings remain mixed. This paper presents an updated meta-analysis of autism outcome studies and extends previous findings with additional analyses (including…

Pasco, Greg; Davies, Kim; Ribeiro, Helena; Tucker, Leslie; Allison, Carrie; Baron-Cohen, Simon; Johnson, Mark H.; Charman, Tony – Journal of Autism and Developmental Disorders, 2021
Parents participating in a prospective longitudinal study of infants with older siblings with autism completed an autism screening questionnaire and were asked about any concerns relating to their child's development, and children were administered an interactive assessment conducted by a researcher at 14 months. Scores on the parent questionnaire…

De Clercq, Lana E.; Dieleman, Lisa M.; van der Kaap-Deeder, Jolene; Soenens, Bart; Prinzie, Peter; De Pauw, Sarah S. W. – Journal of Autism and Developmental Disorders, 2021
This nine-year longitudinal study addresses the joint contribution of parent-rated negative controlling parenting and child personality on psychosocial outcomes in 141 families of children with autism spectrum disorder (83% boys, mean age Time 1 = 10.1). Latent change modeling revealed substantial variation in within-person change in parenting and…

Shire, Stephanie Y.; Shih, Wendy; Chang, Ya-Chih; Bracaglia, Suzanne; Kodjoe, Maria; Kasari, Connie – Journal of Autism and Developmental Disorders, 2019
Intervention research is increasingly conducted in community settings, however it is not clear how well practices are sustained locally or how children progress once external research support is removed. Two school-year cohorts of toddlers with autism (year 1: n = 55, year 2: n = 63) received Joint Attention, Symbolic Play, Engagement, and…

Meyer, Allison T.; Powell, Patrick S.; Butera, Nicole; Klinger, Mark R.; Klinger, Laura G. – Journal of Autism and Developmental Disorders, 2018
Research suggests that individuals with autism spectrum disorder (ASD) have significant difficulties with adaptive behavior skills including daily living and functional communication skills. Few studies have examined the developmental trajectory of adaptive behavior across childhood and adolescence. The present study examined longitudinal…

We integrated multiple behavioural and developmental measures from multiple time-points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n…

Roberts, Jane; Crawford, Hayley; Hogan, Abigail L.; Fairchild, Amanda; Tonnsen, Bridgette; Brewe, Alexis; O'Connor, Shannon; Roberts, Douglas A.; Abbeduto, Leonard – Journal of Autism and Developmental Disorders, 2019
Fragile X syndrome (FXS) is characterized by both social approach and social avoidance. However, the age of emergence and developmental trajectory of social avoidance has not been examined. This study investigates the longitudinal developmental trajectory and dynamic nature of social avoidance in males with FXS from infancy through young adulthood…

Lawson, Lauren P.; Joshi, Rucha; Barbaro, Josephine; Dissanayake, Cheryl – Journal of Autism and Developmental Disorders, 2018
Relatively few studies have examined gender differences in infants and toddlers, and most focus on clinically referred samples or high-risk infant cohorts. The current study aimed to examine gender differences in early autism manifestations and cognitive development in a community-ascertained sample. In total, 46 males and 21 females with ASD were…

Sparaci, Laura; Northrup, Jessie B.; Capirci, Olga; Iverson, Jana M. – Journal of Autism and Developmental Disorders, 2018
Forty-one high-risk infants (HR) with an older sibling with autism spectrum disorder (ASD) were observed longitudinally at 10, 12, 18 and 24 months of age during a tool use task in a play-like scenario. Changes in grasp types and functional actions produced with a spoon were assessed during elicited tool use. Outcome and vocabulary measures were…

Woynaroski, Tiffany; Watson, Linda; Gardner, Elizabeth; Newsom, Cassandra R.; Keceli-Kaysili, Bahar; Yoder, Paul J. – Journal of Autism and Developmental Disorders, 2016
Diversity of key consonants used in communication (DKCC) is a value-added predictor of expressive language growth in initially preverbal children with autism spectrum disorder (ASD). Studying the predictors of DKCC growth in young children with ASD might inform treatment of this under-studied aspect of prelinguistic development. Eighty-seven…

Dynia, Jaclyn M.; Brock, Matthew E.; Logan, Jessica A.; Justice, Laura M.; Kaderavek, Joan N. – Journal of Autism and Developmental Disorders, 2016
Many children with autism spectrum disorder (ASD) struggle with reading. An increased focus on emergent literacy skills--particularly print knowledge--might improve later reading outcomes. We analyzed longitudinal measures of print knowledge (i.e., alphabet knowledge and print-concept knowledge) for 35 preschoolers with ASD relative to a sample of…

Myers, Emily; Davis, Beth Ellen; Stobbe, Gary; Bjornson, Kristie – Journal of Autism and Developmental Disorders, 2015
Individuals with Autism Spectrum Disorders (ASDs) are at increased risk for poor psychosocial outcomes as adults. We described community and social participation in adolescents with ASDs as they transitioned from adolescence to adulthood, and identified adolescent factors associated with community and social participation outcomes in adulthood. We…
