Study Details
Setting
The setting for this study was a pre-kindergarten inclusion classroom and an outdoor educational space at a university-based early childhood education center.
Study sample
Three students diagnosed with a developmental disability between the ages of 3 to 5 years old participated in the study. Sutton, age 5, was diagnosed with an Autism Spectrum Disorder. Elliott, age 5, was diagnosed with Downs Syndrome. Simon, age 5, was diagnosed with a cognitive and social delay but was also being monitored for Autism.
Intervention Group
The study used an intervention package that combined three approaches, including visual supports, scripts, and least-to-most prompting. Toys were introduced to the students and then the interventionists used a least-to-most prompting technique to move the student through the play script. As students gained skills with the materials, the prompting was faded. Two different sets of toys and scripts were used throughout the intervention condition based on the students' interests; these were the same toys used with each student during the baseline sessions. For instance, a dinosaur playset included a volcano, trees, and wooly mammoths; the play script provided a narrative of the scene, such as describing the dinosaur and wooly mammoth climbing the volcano and the volcano being hot. Students were allowed to bring in additional materials and deviate from the script as they played. All play sessions were 15 minutes in length for a total of 11 intervention sessions for Elliott, six for Simon, and nine for Sutton.
Comparison Group
There is no comparison group in single-case designs. All play sessions were 15 minutes in length for a total of three baseline sessions for Elliott, four for Simon, and five for Sutton, for each toy set. Two different toy sets were used throughout the baseline condition based on the student's interest. The interventionists provided no prompting to the student to use the toys.
Support for implementation
The study collected data on the fidelity of program implementation via a fidelity checklist. If fidelity fell below 90 percent for more than two consecutive weeks, the study team would provide the interventionist with a booster training. Fidelity never fell below the threshold, so no booster training was needed during the study.
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).
