To explore issues surrounding re-consenting youth in longitudinal studies as they reach legal adulthood interviews were conducted with 46 parents plus 13 autistic teens enrolled in the Simons Foundation Powering Autism Research for Knowledge (SPARK) study. Qualitative analysis focused on family sensitivities regarding guardianship decisions,…

Early intervention for autism spectrum disorder (ASD) tends to focus on enhancing social-communication skills. We report the acceptability, feasibility and impact on child functioning of a new 8 weeks parent-group intervention to manage restricted and repetitive behaviours (RRB) in young children with ASD aged 3-7 years. Forty-five families took…

Many researchers have studied various interventions for individuals with autism spectrum disorder (ASD). Occasionally, siblings will be included in intervention studies, participating in programs designed to address a number of challenges faced by individuals with ASD. Although sibling involvement in such interventions is not a new phenomenon,…

We conducted a meta-analysis of single-subject research studies investigating the effectiveness of antecedent strategies grounded in behavioral momentum for improving compliance and on-task performance for students with autism. First, we assessed the research rigor of those studies meeting our inclusionary criteria. Next, in order to apply a…

This meta-analysis used hierarchical linear modeling to examine 115 single-case studies with 343 participants that examined the effectiveness of social skills interventions for individuals with autism spectrum disorder (ASD). The average effect size of the included studies was 1.40 (SD = 0.43, 95% CL = 1.32-1.48, N = 115). In the further, several…

This paper presents an overview of 5 meta-analyses of early intensive behavioral intervention (EIBI) for young children with autism spectrum disorders (ASDs) published in 2009 and 2010. There were many differences between meta-analyses, leading to different estimates of effect and overall conclusions. The weighted mean effect sizes across…

To address methodological challenges in research on psychosocial interventions for autism spectrum disorder (ASD), a model was developed for systematically validating and disseminating interventions in a sequence of steps. First, initial efficacy studies are conducted to establish interventions as promising. Next, promising interventions are…

This single subject design study examined two models of intervention: Denver Model (which merges behavioral, developmental, and relationship-oriented intervention), and PROMPT (a neuro-developmental approach for speech production disorders). Ten young, nonverbal children with autism were matched in pairs and randomized to treatment. They received…

There has been much research concerning functional assessment over the past 20 years, but several important research considerations have yet to be explained. One is the comparison of different types of functional assessment (e.g., experimental functional analysis and non-experimental functional assessment). The current study aims to compare the…

This paper reviews findings from comprehensive early intervention studies with young children with autism and formulates questions that need to be answered to establish efficacious, accessible early treatment. Results suggest that intensive, very early treatment appears to lessen the debilitating effects of autism. Research questions involve…

Evaluates claims of the Early Intervention Project, an intensive behavioral intervention program for young children with autism. Claims include recovery from autism in 47% of cases and substantial improvement in an additional 42%. The article finds methodological problems affecting internal and external validity of the project's reported results.…
