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.
