Preschool aged children's social and emotional adjustment impacts their behavior across settings. Providing high-quality early intervention services that enhance social and emotional skills can help prepare children for formal schooling and improve social and behavioral outcomes. The summer prior to Kindergarten presents a unique opportunity for community-based settings to implement social and emotional learning initiatives. One program that has been found to be efficacious in increasing social and emotional competence and reducing problem behaviors with younger populations is the Preschool Promoting Alternative Thinking Strategies (Preschool PATHS) program. The purpose of this study was to examine implementation fidelity and social validity of the Preschool PATHS program offered in a community-based setting in the summer. Findings suggest that agency staff can independently implement the Preschool PATHS program with fidelity. Furthermore, ratings revealed that the intervention is socially valid and deemed acceptable by agency staff. The results are presented along with implications for future practice.
