The National Institute of Mental Health created the National Database for Autism Research (NDAR) to accelerate autism knowledge through data sharing and collaboration. However, our experience using NDAR reveals systematic challenges across several aspects of data submission, selection, management, and analysis that limit utility of this resource.…

Joint Attention (JA) and Supported Joint Engagement (Supported JE) have each been reported to predict later language development in typically developing (TD) children and children with Autism Spectrum Disorder (ASD). In this longitudinal study including 33 TD children (20 months at V1) and 30 children with ASD (33 months at V1), the contributions…

This study examined connections between parental quality of life (QoL) and features of children (autism severity, cognitive ability, behavioral profile, and sociodemographic factors). Parents of 97 children attending an autism-specific preschool completed the Quality of Life in Autism, Vineland Adaptive Behavior Scales and Child Behavior…

The Early Learner Curriculum and Achievement Record (ELCAR, Greer et al., 2020) is a criterion-referenced curriculum and assessment of children's development of language and social repertoires from the earliest foundational observing responses to advanced verbal repertoires. The developmental cusps or stages identified in the ELCAR have been…

The establishment of reciprocal friendships is a challenge for many individuals with autism spectrum disorder (ASD). Social interaction difficulties emerge early, persist throughout development, and have widespread functional impact. As such, interventions focused on social functioning are needed in early intervention programs. This two-part study…

The effects of environmental factors [including Socio-Economic Status, Cultural Capital, and Social Capital (Socio-Cultural Level) of both parents] on the Vineland-II adaptive behavior dimensions of toddlers with autism spectrum disorder (ASD), in addition to individual factors, was investigated in 148 Italian toddlers (82% males), aged 18 to…

Most social communication tests used to measure change in young children with autism spectrum disorder have not undergone rigorous psychometric evaluation. Notably, and most relevant to the early intervention literature, there is little information on the sensitivity of these measures to change over time, despite their frequent use. Further, most…

Attending preferentially to social information in the environment is important in developing socio-communicative skills and language. Research using eye tracking to explore how individuals with autism spectrum disorder deploy visual attention has increased exponentially in the past decade; however, studies have typically not included minimally…

Emotional reactivity (e.g. explosive outbursts, tantrums) is a common but understudied challenge for individuals with autism spectrum disorder. Prior research has relied primarily on questionnaire data or observations of very young children. The current study coded emotional reactivity and recovery during a series of standardized frustration tasks…

Reaction to a child's diagnosis can strongly affect the parent, but little is known about the aspects of the diagnostic process associated with such reactions. The pre-diagnostic levels of anxiety, depression, and parenting stress of 67 volunteer mothers of children subsequently diagnosed with autism spectrum disorder were assessed, along with the…

Prenatal exposure to air pollution has been associated with autism spectrum disorder (ASD) risk but no study has examined associations with ASD severity or functioning. Cognitive ability, adaptive functioning, and ASD severity were assessed in 327 children with ASD from the Childhood Autism Risks from Genetics and the Environment study using the…

Although the early behaviors associated with autism spectrum disorder have been well characterized, many behaviors are also commonly observed in young children with other developmental delays and even in those with typical development. Therefore, consideration must be given to whether a child demonstrates sufficient autism spectrum disorder…

We assessed potential factors associated with "current" or "ever" self-injurious behaviors, reported in the Autism Diagnostic Interview-Revised, among children with autism spectrum disorder (n = 692) from the Study to Explore Early Development. Data on factors examined were obtained from questionnaires, standardized clinical…

Individuals with autism spectrum disorder (ASD) tend to have significant delays in adaptive functioning. In this study, the relationship between adaptive behavior and ASD symptomatology was investigated in minimally verbal, school-aged children with ASD (n = 333). Both the social affect (SA) and restricted and repetitive behavior (RRB) domains…

This study explores current reading profiles and concurrent and early predictors of reading in children with autism spectrum disorder. Before the age of 3 years, the study cohort underwent a neurodevelopmental assessment following identification in a population-based autism screening. At age 8 years, reading, language and cognition were assessed.…
