Background: Reliance on moral principles and professional codes has given nurses direction for ethical decision-making. However, rational models do not capture the emotion and reality of human choice. Intuitive response must be considered. Research purpose: Supporting intuition as an important ethical decision-making tool for nurses, the aim of this study was to determine relationships between intuition, years of worked nursing experience, and perceived ethical decision-making ability. A secondary aim explored the relationships between rational thought to years of worked nursing experience (...) and perceived ethical decision-making ability. Research design and context: A non-experimental, correlational research design was used. The Rational Experiential Inventory measured intuition and rational thought. The Clinical Decision Making in Nursing Scale measured perceived ethical decision-making ability. Pearson’s r was the statistical method used to analyze three primary and two secondary research questions. Participants: A sample of 182 emergency nurses was recruited electronically through the Emergency Nurses Association. Participants were self-selected. Ethical considerations: Approval to conduct this study was obtained by the Adelphi University Institutional Review Board. Findings: A relationship between intuition and perceived ethical decision-making ability ( r =.252, p =.001) was a significant finding in this study. Discussion: This study is one of the first of this nature to make a connection between intuition and nurses’ ethical decision-making ability. Conclusion: This investigation contributes to a broader understanding of the different thought processes used by emergency nurses to make ethical decisions. (shrink)
