Evidence-based practice (EBP) is receiving increased attention from vocational rehabilitation (VR) professionals as the demand for accountability in rehabilitation and healthcare systems expands. The purpose of the current study was to determine the level of understanding VR professionals have of EBP with specific attention to perceived self-efficacy, outcome expectancy, barriers, and readiness to use evidence in current practice. Data were collected from 396 rehabilitation counselors, who were recruited from four state VR agencies. Results indicate self-efficacy and outcome expectancy were positively associated with readiness to use EBP, and agency barriers and personal barriers were negatively related to readiness to use EBP. These social-cognitive predictors accounted for 44% of the variance in the stages of change scores, and outcome expectancy was the most significant predictor after controlling for the effect of perceived self-efficacy and barriers. To increase EBP among rehabilitation counselors, efforts should focus on increasing self-efficacy and outcome expectancy of EBP.
