Teacher attitudes toward evidence-based practices: Exploratory and confirmatory analyses of the school-adapted evidence-based practice attitude scale

Abstract

Background The Evidence-Based Practice Attitudes Scale (EBPAS) is widely used in implementation research, but it has not been adapted and validated for use among general education teachers, who are most likely to deliver evidence-based prevention programs in schools, the most common setting where youth access social, emotional, and behavioral health services. Method School-based stakeholders and a research team comprised of experts in the implementation of evidence-based practices in schools adapted the EBPAS for teachers (the S-EBPAS). The adapted instrument was administered to a representative sample ( n = 441) of general education teachers (grades K—5) to assess the reliability and internal consistency via factor analyses. The S-EBPAS included two forms (i.e., EBP-agnostic and EBP-specific item referents), therefore, a multiple-group confirmatory factor analysis (CFA) was also performed to establish measurement invariance between the two forms. Results After adaptation and refinement, a 9-item, 3-factor structure was confirmed, with the final model supporting three first-order factors that load onto a second-order factor capturing attitudes toward adopting evidence-based practices. Multiple-group CFA analyses of measurement invariance indicated there were no significant differences between the two forms. Conclusions Overall, this study provides a brief, flexible instrument capturing attitudes toward adopting EBPs that has high reliability and internal consistency, which support its use among general education teachers in school settings implementing evidence-based practices.
