This paper explores the domains of influence affecting practice nurses’ ability to find, evaluate and use clinical evidence. A cross-sectional survey of general practice nurses (n = 590) in Victoria, Australia in 2008 provided data for a principal components analysis. The research replicates a study undertaken in the UK using the Developing Evidence-Based Practice Questionnaire. Five domains of influence on nurses’ translation of evidence were identified: skills in finding/reviewing evidence; barriers to finding/reviewing evidence; knowledge from published sources; knowledge from other sources; and barriers or facilitators to change. Each domain was interpreted as underlying the relationship of nurses with evidence-based practice and was comparable to the original study’s findings when subjected to factor analysis. Findings from this study show that the Developing Evidence-Based Practice Questionnaire—Au is a valid and useful instrument in determining the influences on practice nurses’ ability to effect knowledge translation and conduct practice based on evidence. Given these findings, a new model is proposed that explains the influence of a number of domains on Australian general practice nurses’ translation of knowledge into practice.
