Development and psychometric evaluation of a quality nursing care scale from nurses' perspective.

The EFA extracted six factors including staff characteristics, task-oriented activities, human-oriented activities, physical environment, patient outcomes and precondition. All six factors accounted for 74.78% of the total variance to explain quality nursing care. The modified measurement model of the final version of QNCS was supported by the CFA with 48 items in six dimensions. The internal consistency reliability of final QNCS was acceptable.
