Factors Influencing Undergraduate Students' Intention to Use Evidence-Based Practice After Graduation: Development and Validation of a Theory-Based Prediction Model.

BACKGROUND

Despite curriculum requirements for evidence-based practice (EBP) to be a key component of undergraduate health students' training, few studies have investigated factors influential to students' intention to use EBP after graduation. Self-efficacy is known to mediate and motivate behavior; therefore, it may be a crucial factor linking undergraduate students' EBP education and adoption of positive EBP behaviors.

AIMS

To develop, test, and validate a multivariate, theory-based prediction model with the outcome of students' intention to use EBP after graduation.

METHODS

A correlational study with structural equation modeling was conducted. Model factors were determined from Bandura's self-efficacy theory and previous literature. An online survey comprised of seven validated scales and a demographic tool was distributed to a sample of undergraduate nursing and paramedic students. Two episodes of data collection were conducted to test and validate the model.

RESULTS

Evidence-based practice beliefs directly and significantly influenced student intention to use EBP in both models. Sources of EBP self-efficacy also had significant but indirect influence on the outcome variable. Overall variance for intention to use EBP was 25% for the initial model and 18% for the validated model.

LINKING EVIDENCE TO ACTION

Evidence-based practice curriculum that supports positive EBP beliefs and integrates Bandura's sources of self-efficacy has potential to positively influence students' intention to use EBP after graduation.
