Ethical decision-making confidence scale for nurse leaders: Psychometric evaluation

Ethical decision-making confidence develops from clinical expertise and is a core competency for nurse leaders. No tool exists to measure confidence levels in nurse leaders based upon an ethical decision-making framework.

The objective of this research was to compare ethical decision-making among nurse leaders in the U.S. and three German-speaking countries in Europe by developing and testing a newly constructed Ethical Decision-Making Confidence (EDMC) scale.

The cross-sectional survey included 18 theory-derived questions on ethical decision-making confidence which were used to develop the scale.

A convenience sample of nurse leaders from the U.S. and three German-speaking countries in Europe who self-identified as holding a leadership position.

Ethical approval was given by the IRB Board of a U.S. university. Participation in the survey implied voluntary consent.

The scale's item structure dimensionality and subscale's reliability were analyzed and compared between nurse leaders from all four countries. A principal component analysis (PCA) produced a 15-item bi-dimensional EDMC scale yielding a skill-related (9-item) and a behavior-related (6-item) confidence dimension. EDMC subscales showed good-to-excellent internal consistency. In both subscales, U.S. nurse leaders rated their mean EDMC score higher than their German-speaking counterparts in Europe.

This exploratory study is the first of its kind to focus on nurse leaders' confidence regarding ethical decision-making in an international context. An overarching factor structure was identified, which is shared by the two samples of nurse leaders and to examine (sub)scales' psychometric properties.

This newly developed scale is an effective tool for measuring ethical decision-making confidence in nurse leaders. The promising results of this study should be replicated to ensure validity and reliability of the EDMC scale measuring skill-related and behavior-related concepts and include nurse leaders from various cultural, social, and demographic groups.
