Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Children receive a minimum of 20 hours a week of intervention using the Early Start Denver Model (ESDM) in a group setting. They also receive 1 hour a week of individual ESDM therapy. The ESDM will be administered for the duration of the children's attendance at the childcare centre. Children will complete assessments on entry to the childcare centre, and then on exit from the centre or at twelve months after entry, whichever occurs first.

The assessments administered at both timepoints will be the Autism Diagnostic Observation Schedule and the Mullen Scales of Early Learning. In addition, parents will be asked to complete a battery of self-report scales: the Social Communication Questionnaire (SCQ), the Vineland Adaptive Behaviour Scale (VABS), the Depression Anxiety and Stress Scale (DASS-21), the Parent Sense of Competence Scale (PSOC), the Quality of Life in Autism Spectrum Disorders Questionnaire (QoLA). These measures are further detailed in the outcome fields of this form.

The ESDM uses teaching strategies that involve interpersonal exchange and positive affect, shared engagement with real-life materials and activities, adult responsivity and sensitivity to child cues, and focus on verbal and nonverbal communication, based on a developmentally informed curriculum that addresses multiple developmental domains, namely Receptive Language, Expressive Language, Social Interaction, Fine/Gross Motor Skills, Imitation, Cognition, Play Skills, and Adaptive Behaviour/Personal Independence.

All therapists are trained on the administration and scoring of the ESDM and must demonstrate and maintain fidelity.

Treatment: Other
Comparator / control treatment
There will be two comparator/control groups:
Typically Developing Control Group: Forty typically developing children attending a mainstream preschool will be recruited and complete the same battery of clinical assessments as the intervention group at baseline and after 12 months.
Treatment as Usual Group: Forty children currently diagnosed with ASD from the community will be recruited and complete the same battery of clinical assessments as the intervention group at baseline and after 12 months.

The assessments administered with the comparator/control groups will be the Autism Diagnostic Observation Schedule and the Mullen Scales of Early Learning. In addition, parents will be asked to complete a battery of self-report scales: the Social Communication Questionnaire (SCQ), the Vineland Adaptive Behaviour Scale (VABS), the Depression Anxiety and Stress Scale (DASS-21), the Parent Sense of Competence Scale (PSOC), the Quality of Life in Autism Spectrum Disorders Questionnaire (QoLA). These measures are further detailed in the outcome fields of this form. While the comparator/control groups will receive the battery of baseline and 12-month assessments, they will not receive the ESDM intervention.

Treatment as usual group will not receive ESDM intervention, but will receive whatever interventions the children and family access of their own accord. We will gather this information about any other treatments received during the study period.
