Turner, Lauren M.; Stone, Wendy L. – Journal of Child Psychology and Psychiatry, 2007
Background: Few studies have examined the variability in outcomes of children diagnosed with autism spectrum disorder (ASD) at age 2. Research is needed to understand the children whose symptoms--or diagnoses--change over time. The objectives of this study were to examine the behavioral and diagnostic outcomes of a carefully defined sample of…

Matson, Johnny L.; Wilkins, Jonathan; Sharp, Brenda; Knight, Cheryl; Sevin, Jay A.; Boisjoli, Jessica A. – Research in Autism Spectrum Disorders, 2009
Early identification of autism spectrum disorders (ASD) is now considered best practice in the field of developmental disabilities. Despite calls by national pediatric organizations and others for routine screening in young children, such recommendations have been hard to implement in practice. One of the major unresolved problems is the need for…

Luyster, Rhiannon; Lord, Catherine – Developmental Psychology, 2009
Autism spectrum disorders (ASD) have been gaining attention, partly as an example of unusual developmental trajectories related to early neurobiological differences. The present investigation addressed the process of learning new words to explore mechanisms of language delay and impairment. The sample included 21 typically developing toddlers…

Adamson, Lauren B.; Bakeman, Roger; Deckner, Deborah F.; Romski, MaryAnn – Journal of Autism and Developmental Disorders, 2009
Systematic longitudinal observations were made as typically developing toddlers and young children with autism and with Down syndrome interacted with their caregivers in order to document how joint engagement developed over a year-long period and how variations in joint engagement experiences predicted language outcome. Children with autism…

Boyd, Brian A.; Odom, Samuel L.; Humphreys, Betsy P.; Sam, Ann M. – Journal of Early Intervention, 2010
The increased prevalence of autism spectrum disorder (ASD) and its detection during the first 3 years of life have substantial relevance for early intervention. The purpose of this article is to summarize current scientific and policy information on early identification and early intervention for infants and toddlers with ASD and their families.…

Roos, Elizabeth M.; McDuffie, Andrea S.; Weismer, Susan Ellis; Gernsbacher, Morton Ann – Autism: The International Journal of Research and Practice, 2008
Children on the autism spectrum often demonstrate atypical joint attention, leading some researchers to consider joint attention deficits a core feature of the autism spectrum. Structured measures, such as the Early Social Communication Scales (ESCS), are commonly used to provide a metric of joint attention. To explore the assessment of joint…

Matson, Johnny L.; Mahan, Sara; Sipes, Megan; Kozlowski, Alison M. – Journal of Mental Health Research in Intellectual Disabilities, 2010
Comorbid psychopathology and challenging behaviors often occur among persons with developmental disabilities. However, little attention to this issue has been reported in young children. In this study, individuals 17 through 36 months of age with varying diagnoses, such as intellectual disability, developmental delay, and Down syndrome, among…

Kleinman, Jamie M.; Robins, Diana L.; Ventola, Pamela E.; Pandey, Juhi; Boorstein, Hilary C.; Esser, Emma L.; Wilson, Leandra B.; Rosenthal, Michael A.; Sutera, Saasha; Verbalis, Alyssa D.; Barton, Marianne; Hodgson, Sarah; Green, James; Dumont-Mathieu, Thyde; Volkmar, Fred; Chawarska, Katarzyna; Klin, Ami; Fein, Deborah – Journal of Autism and Developmental Disorders, 2008
Autism spectrum disorders (ASD) often go undetected in toddlers. The Modified Checklist for Autism in Toddlers (M-CHAT) was used to screen 3,793 children aged 16-30 months from low- and high-risk sources; screen positive cases were diagnostically evaluated. Re-screening was performed on 1,416 children aged 42-54 months. Time1 Positive Predictive…

Hartley, Sigan L.; Sikora, Darryn M. – Journal of Autism and Developmental Disorders, 2009
Little is known about the female presentation of autism spectrum disorder (ASD) during early childhood. We investigated sex differences in developmental profiles using the Mullen Scales of Early Learning, autistic symptoms on the ADOS-G, and coexisting behavior problems on the CBCL in 157 boys and 42 girls with ASD aged 1.5-3.9 years. Overall,…

Drew, Auriol; Baird, Gillian; Taylor, Emma; Milne, Elizabeth; Charman, Tony – Journal of Autism and Developmental Disorders, 2007
The Social Communication Assessment for Toddlers with Autism (SCATA) was designed to measure non-verbal communication, including early and atypical communication, in young children with autism spectrum disorder. Each communicative act is scored according to its form, function, role and complexity. The SCATA was used to measure communicative…

Loh, Alvin; Soman, Teesta; Brian, Jessica; Bryson, Susan E.; Roberts, Wendy; Szatmari, Peter; Smith, Isabel M.; Zwaigenbaum, Lonnie – Journal of Autism and Developmental Disorders, 2007
This study examined motor behaviors in a longitudinal cohort of infant siblings of children with autism. Stereotypic movements and postures occurring during standardized observational assessments at 12 and 18 months were coded from videotapes. Participants included eight infant siblings later diagnosed with autism spectrum disorder (ASD), a random…

Snow, Anne V.; Lecavalier, Luc – Autism: The International Journal of Research and Practice, 2008
This study assessed the psychometric properties of the Modified Checklist for Autism in Toddlers (M-CHAT) and the Social Communication Questionnaire (SCQ) in a sample of preschool children referred for possible pervasive developmental disorders (PDDs). The sample consisted of 82 children between the ages of 18 and 70 months (54 with a PDD…

Honda, Hideo; Shimizu, Yasuo; Nitto, Yukari; Imai, Miho; Ozawa, Takeshi; Iwasa, Mitsuaki; Shiga, Keiko; Hira, Tomoko – Journal of Child Psychology and Psychiatry, 2009
Background: For early detection of autism, it is difficult to maintain an efficient level of sensitivity and specificity based on observational data from a single screening. The Extraction and Refinement (E&R) Strategy utilizes a public children's health surveillance program to produce maximum efficacy in early detection of autism. In the…

Chiang, Chung-Hsin; Soong, Wei-Tsuen; Lin, Tzu-Ling; Rogers, Sally J. – Journal of Autism and Developmental Disorders, 2008
Objective: The study was to examine nonverbal communication in young children with autism. Methods: The participants were 23 young children with autism (mean CA = 32.79 months), 23 CA and MA-matched children with developmental delay and 22 18-20-month-old, and 22 13-15-month-old typically developing toddlers and infants. The abbreviated Early…

A diagnosis of autism spectrum disorder (ASD) is usually taken to be permanent. In this study, 13 two-year-old children with ASD lost the diagnosis by age 4, at which time they scored within the normal range on standardized measures of cognitive and adaptive functioning. No differences were found in symptom severity, socialization, or…
