Evaluation of Social ABCs With Attention Training Intervention for Toddlers With Suspected Autism

Plain-language summary

The Social ABCs is an evidence-based, developmentally informed, caregiver-mediated behavioural intervention for toddlers with suspected or confirmed Autism Spectrum Disorder (ASD). It is based on principles of Pivotal Response Treatment (PRT, grounded in Applied Behaviour Analysis), and responsive parenting. The two key targets of this program are functional verbal communication and positive caregiver-child affect sharing. This intervention takes place in the context of play and daily routines, and in all contexts is made to be fun, natural and motivating for the child. In both a pilot study and a recently completed randomized control trial, toddlers whose caregivers received training in the Social ABCs intervention showed significant gains in early language development (both responsivity and initiations), increased child smiling (mediated by parent smiling), and a trend toward increased social orienting (one important manifestation of social attention). Despite the social-communication benefits demonstrated through the Social ABCs, the research team is also motivated to foster the attentional abilities of toddlers with emerging ASD in response to compelling evidence that early attentional control abilities may play a central role in the emergence of ASD. Based on this knowledge, the current study targets not only social-communication challenges and affect sharing (as per the existing Social ABCs intervention), but also attentional control in toddlers with suspected or confirmed ASD. Using a structured, computerized attention-training protocol, this RCT evaluates the impact of supplementing the standard Social ABCs intervention with pre-intervention attentional control training.
