Background and purpose: The objectives of this study were to develop a National Nursing Core Competency Standards (NNCCS)-based instrument and determine its construct validity and internal consistency reliability.
Methods: A methodologic research design was used to validate the 59-item scale based on the responses of 600 nurses. The scale items were culled from the client care, leadership and management, and research competencies identified in the NNCCS.
Results: The results of the analyses confirmed 53 items and gave rise to a five-factor solution. The five dimensions are leadership, management, research, ethico-legal, and strategic competencies.
Conclusions: The seminal psychometric testing provided an evidence of acceptable validity and reliability of the proposed instrument. Further testing was recommended to accrue the psychometric soundness of the instrument.
