This study examined the psychometric properties of the Evidence-Based Practice Questionnaire (EBPQ). The 24-item EBPQ was developed to measure health professionals’ attitudes toward, knowledge of, and use of evidence-based practice (EBP). A confirmatory factor analysis was performed on the EBPQ given to a random sample of National Association of Social Work members (N = 167). The coefficient alpha of the EBPQ was .93. The study supported a 23-item 3-factor model with acceptable model fit indices (χ² = 469.04; RMSEA = .081; SRMR = .068; CFI = .900). This study suggests a slightly modified EBPQ may be a useful tool to assess social workers’ attitudes toward, knowledge of, and use of EBP.
