The school-age outcomes of autistic children who received early interventions (EI) remains limited. Adaptive functioning, social, peer play skills, problem behaviours, and attitudes towards school of 31 autistic children who received community-based group early start Denver model (G-ESDM) were compared to 28 age matched autistic children who…

This study assessed the effects of portable video modeling on social interactions of four children with autism, three boys and one girl, 4- to 5-year-olds, in preschools in Iceland. Participants were shown 1-min videos on a small handheld device where a peer model initiated social interactions and played with two peers. A…

Social engagement, pretend play, and concern for another's distress represent fundamental features of typical social-emotional development in the second year. Children with autism spectrum disorder (ASD) display delays and deficits in these areas, and research on toddlers at heightened risk for ASD (HR; younger siblings of children with ASD)…

This RCT study examined efficacy of a preschool peer social intervention (PPSI) in facilitating social engagement of preschoolers with high-functioning ASD (HFASD; N = 65). HFASD participants were randomly assigned by preschool to a 6-month intervention (play, interaction, or conversation) or a waitlisted-treatment-as-usual control group. Trained…

We compared the effectiveness of two programs for developing social skills, 'Play Time/Social Time' (PT/ST) and 'I Can Problem Solve' (ICPS), in improving the social skills and theory of mind (ToM) of preschoolers with ASD. The experiment took place in a classroom setting. Fifty-two children attended and data were analyzed with latent growth curve…

Despite widespread clinical use of group-based social skills training (SST) for children with autism spectrum disorder (ASD), there remains a lack of follow-up data, generalisation effects, common definition of social skills, and teacher report data. This study evaluated the effectiveness of an 8-week SST intervention with a play component…

Toddlers with an older sibling with autism spectrum disorder (ASD) and low risk (LR) toddlers with typically-developing older siblings were observed during free play with a parent and elicited pretend with an examiner at 22-months. Functional and pretend play, children's social engagement, and parent sensitivity were assessed during free play.…

Children with autism spectrum disorders (ASD) face pervasive challenges in symbolic and social play development. The Integrated Play Groups (IPG) model provides intensive guidance for children with ASD to participate with typical peers in mutually engaging experiences in natural settings. This study examined the effects of a 12-week IPG…

This study examined associations between three parent-child engagement states and social communication, expressive language, and receptive language at 8 month follow-up, in 63 preschool-age children with autism spectrum disorder. We extend the literature on supported joint engagement by dividing this state into higher order (HSJE) and lower order…

The extent to which early social communication behaviors predict later communication and intellectual outcomes was investigated via retrospective video analysis. Joint attention, imitation, and complex object play behaviors were coded from edited home videos featuring scenes of 29 children with ASD at 9-12 and/or 15-18 months. A quantitative…

Past research has focused on pretend play in infants with autism because it is considered an early manifestation of symbolic or imaginative thinking. Contradictory research findings have challenged the meta-representational model. The intent of this paper is to propose that pretend play is the behavioral manifestation of developing imaginative…

Play and social abilities of a group of children diagnosed with high functioning autism were compared to a second group diagnosed with a variety of developmental language disorders (DLD). The children with autism engaged in fewer acts of high level play. The children with autism also had significantly lower social functioning than the DLD group…

We examined social attention and attention shifting during (a) a play interaction between 12-month olds and an examiner and (b) after the examiner pretended to hurt herself. We coded the target and duration of infants' visual fixations and frequency of attention shifts. Siblings of children with autism and controls with no family history of autism…

Children with autism face enormous struggles when attempting to interact with their typically developing peers. More children are educated in integrated settings; however, play skills usually need to be explicitly taught, and play environments must be carefully prepared to support effective social interactions. This study incorporated the…

We piloted a 2-week "Autism-1-2-3" early intervention for children with autism and their parents immediately after diagnosis that targeted at (1) eye contact, (2) gesture and (3) vocalization/words. Seventeen children were randomized into the Intervention (n = 9) and Control (n = 8) groups. Outcome measures included the Autism Diagnostic…
