Background: The current study was conducted to develop and validate an instrument to measure the use of intuition in clinical practice by critical care nurses.
Methods: Item generation and psychometric evaluation were developed. In the psychometric, content validity index and content validity ratio were calculated to establish initial instrument validity through the use of expert ratings, as well as, construct and criterion validity.
Results: The original items reduced to 25. Using principal components analysis and orthogonal varimax rotation, three factors had an eigenvalue >1, with 60.05% variance (Factor 1: 47.9%; Factor 2: 7.56%; and Factor 3: 5.05%). The tool had an acceptable correlation to criterion of the instrument (r = .769, p < .001), a Cronbach alpha consistency of 0.953, and a stability level of r = .945 and p < .001.
Conclusion: In this study, a valid and reliable instrument was developed to measure intuition.
