Abstract
Study objectives: To implement Tier 1 support of school-wide positive behavior support (SWPBS) and to examine its effectiveness and social validity. Design: AB design. Setting: One public elementary school. Participants: All school personnel and all students at the school. Intervention: A positive behavior matrix was developed, and behavior support plans for each target behavior were developed and implemented. Measures: A tally of the number of students engaged in the targeted behaviors, and data obtained using an interval recording method. In addition, a rating scale was administered 3 times, and the average scores of all students at each administration were compared. Social validity data were collected using a questionnaire. Results: The target behaviors increased after the intervention, and scores on the rating scale improved, suggesting a certain social validity. Conclusion: The results suggest that the Tier 1 support implemented in the present study was effective and had acceptable social validity. However, several challenges were identified, including problems with team management and with moving to Tiers 2 and 3 support, as determined by the data and the reliability of the data.
