Imitation has an important place in the observational learning process. Children with autism spectrum disorder (ASD) may experience limitations in imitation ability. These limitations are associated with deficits in abilities associated with ASD including understanding intention. In this study, the imitation skills and intention understanding…

Several studies have shown the efficacy and effectiveness of the Early Start Denver Model, both in university and in community-based settings. However, a limited number of studies have investigated predictors of outcomes. In this study, we examined outcomes in 32 children diagnosed with autism spectrum disorder after 1 year of community-based…

Given the importance of parent involvement and parent-implemented interventions in achieving maximum child outcomes, practitioners need valid measures to assess and monitor family outcomes in developing and delivering effective and sustainable interventions. This study examined the structure of the Family Outcomes Survey, Form A, using a sample of…

Trajectories of expressive language development are highly heterogeneous in autism. Yoder et al. found that parental responsiveness, child response to joint attention, child communicative intent and consonant inventory were unique predictors of expressive language growth in minimally verbal preschoolers 16 months later (n = 87). This study applied…

The diagnosis of autism spectrum disorder (ASD) in a child affects family processes, increases parenting stress and marital conflicts, and may lead to parental psychopathology. It may also affect the prognosis for their children. The aim of this study is to determine depression and burnout levels as well as their predictors among parents of…

Purpose: This research explored syntactic growth in children with fragile X syndrome (FXS) over a 5-year period, and variability in growth in relation to autism symptoms, nonverbal cognition, maternal responsivity, and gender. Method: Language samples at 4 time points from 39 children with FXS, 31 boys and 8 girls, were analyzed using the Index of…

In the current study, we investigated the effects of an instructional package (i.e., response prompting, sentence frames) on sentence writing for three middle school participants (ages 12-13) with moderate to severe disabilities. We employed a multiple probe across behaviors design to evaluate the efficacy of the intervention package and also used…

Autism is widely believed to be a heterogeneous disorder; diagnosis is currently based solely on clinical criteria, although genetic, as well as environmental, influences are thought to be prominent factors in the etiology of most forms of autism. Our goal is to determine whether a predictive model based on single-nucleotide polymorphisms (SNPs)…

The transition to adulthood and adulthood itself have been identified as times of stress for parents of individuals with autism spectrum disorder. Longitudinal studies, however, show improvements in the well-being of mothers of adolescents and young adults with autism spectrum disorder. This article presents a cross-sectional study of 102 Spanish…

More than a decade has passed since the National Research Council described the common elements of effective educational programs for young children with autism. Since that time, few studies have attempted to understand the mechanisms of change and factors affecting the effectiveness of research supported interventions implemented in community…
