Studies demonstrate that discrepancies among leader-follower perceptions of leadership are related to organizational processes that may impact evidence-based practice (EBP) implementation. However, it is unknown whether discrepancies in leadership perceptions also predict EBP use. This study examined the association of principal-staff alignment and discrepancy in perceptions of implementation leadership with the dosage of three Autism-focused school-based EBPs, Discrete Trial Training, Pivotal Response Training (PRT), and Visual Schedules. PRT dosage was higher when principals under-rated their implementation leadership and when it was agreed upon that implementation leadership was low. Findings have implications for leaders support of EBPs implemented in school-based settings.
