Study Details
Setting
The study took place in the homes of caregivers of children between the ages 13 and 16 months, located in six central counties in North Carolina.
Study sample
The study was a non-compromised individual-level RCT that included multiple sites. The researchers randomly assigned 45 children (between the ages of 13 and 16 months) to the intervention group and 42 children (between the ages of 13 and 16 months) to the comparison group. A total of 87 children were included in the study. To be eligible for the study, children had to have been identified as high risk for being diagnosed with autism spectrum disorder, have had a birth weight greater than 2,500 grams, had availability of one caregiver to participate in home-based intervention sessions, and live in a household wherein English was the primary language. The researchers also purposefully recruited only non-Hispanic families. Approximately 69% of the children were male and 31% were female; 69% of the sample were White, 21% were Black, and 10% were mixed race or another race; 99% of the sample were non-Hispanic and 1% did not report ethnicity (all were in the comparison condition). The study did not report other demographic information.
Intervention Group
The Adaptive Responsive Teaching (ART) intervention is a program that was tailored by the research team to be appropriate for children at risk of an autism diagnosis and is delivered to parents or caregivers in a home setting. This intervention focused on bolstering skills related social-communication (such as social play, conversation, and vocalization) and sensory regulation (such as self-regulation, attention, and cooperation). The planned dosage was 30 in-home sessions and six additional contacts through phone or email across six to eight months.
Comparison Group
Children in the comparison group received business-as-usual support and were assigned to the Referral to Early Intervention and Monitoring (REIM) group. The caregivers of children assigned to this condition did not receive any intervention services from the intervention team. Caregivers who asked for EI services were supported by the research team to receive contact information for community EI services (caregivers in both the intervention and comparison group had this option available, so access to REIM did not differ by condition).
Support for implementation
Six interventionists supported the implementation of the intervention and had experience in child development, ASD, and EI. The interventionists held education sessions to introduce the ART intervention to caregivers and provide supporting materials on how to use ART in their homes.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.

Study findings for this report.
Based on the direction, magnitude, statistical significance, and sample size of the findings within a domain, the WWC assigns effectiveness ratings as one of the following: Tier 1 (strong evidence), Tier 2 (moderate evidence), Tier 3 (promising evidence), uncertain effects, and negative effects. For more detail, please see the WWC Handbook.
The WWC may review studies for multiple purposes, including different reports and re-reviews using updated standards. Each WWC review of this study is listed in the dropdown. Details on any review may be accessed by making a selection from the drop down list.
Tier 1 Strong indicates strong evidence of effectiveness,
Tier 2 Moderate indicates moderate evidence of effectiveness, and
Tier 3 Promising indicates promising evidence of effectiveness,
as defined in the
non-regulatory guidance for ESSA
and the regulations for ED discretionary grants (EDGAR Part 77).
