Based on the Revised Nursing Work Index (NWI-R), this research aimed to develop a Korean Hospital General Inpatient Unite-Nursing Work Index (KGU-NWI). This study also aimed to compare the common points and differences between the subfactors of the KGU-NWI and the subfactors from previous studies.
Based on opinions from 3,151 nurses in Korean hospital general inpatient unit, this research used 57 items of NWI-R and the principal axis factor analysis for deriving subfactors. We evaluated the convergent validity through factor analysis and the content validity of KGU-NWI in terms of the association between nurses' job outcome and the subfactors derived.
Six subfactors and 26 items for KGU-NWI were derived from NWI-R. Among them, 'physician-nurse relationship', 'adequate nurse staffing' and 'organizational support and management of hospital' were the same with results from previous studies. In addition, two subfactors, 'participation of decision-making processes' and 'education for improving quality of care', which were similar with results from previous Korean studies, were newly added by using Korean hospital cases. In contrast to previous Korean studies, a unique subfactor this study found was 'nursing processes'. This research confirmed that the six subfactors were highly correlated with job satisfaction, intention to leave, and quality of health care, which represented a nurse's job outcome.
KGU-NWI including six subfactors and 26 items is an applicable instrument to investigate nurse work environment in Korean hospital general inpatient unit.
