Objective: This report describes the reliability and validity of the Evidence-Based Practice Process Assessment Scale (EBPPAS)–Short Version, validated with three disciplines (Social Work, Licensed Marriage and Family Therapists (LMFTs), and Psychologists), that assesses practitioners’ perceived familiarity with, attitudes about, and implementation of the evidence-based practice (EBP) process. Method: Social work practitioners, psychologists and LMFTs (N = 1001) were surveyed to assess the scale’s internal consistency reliability and criterion and factorial validity. Results: Findings support the scale’s internal consistency reliability, criterion and factorial validity. Conclusion: These findings support the use of the shorter version of the EBPPAS scale in surveys or to evaluate efforts to educate a wide range of behavioral health practitioners in EBP.
