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

The Evidence-Based Practice Attitudes Scale (EBPAS) is a popular instrument for measuring attitudes toward evidence-based practices (EBPs). This instrument provides valuable information during implementation initiatives, such as whether providers or front-line implementers have favorable attitudes toward a given practice. The EBPAS has been used in many different settings, such as in community-based mental health clinics, medical hospitals, and in child welfare. However, it's use in schools has been limited, and it has not yet been tested with general education teachers, who are key implementers of evidence-based practices in schools. In order to trust that the scores from an instrument are accurate, it needs to be evaluated when scaling it out to new populations and settings. One popular method to determine this is to use factor analysis, which was employed in this study. This study fills the identified gap by assessing the reliability (i.e., accuracy) and internal consistency of the EBPAS among a representative sample of general education teachers. Findings from this study indicate that the school-adapted EBPAS (S-EBPAS) is a brief, nine-item instrument that provides a reliable estimate of teachers' attitudes toward evidence-based practices. Our results also provide evidence that the S-EBPAS can be used to capture attitudes toward EBPs as well as attitudes toward EBP This study provides a flexible instrument that can be used by school-based implementation researchers, practitioners, and intermediaries at multiple phases of implementation projects, such as when exploring a new EBP to adopt.
