RESUMEN
PURPOSE: The purpose of this study was to evaluate the validity and reliability of the Korean Version of the Nurses' Self-Concept Instrument (NSCI) geriatric hospital nurses in Korea. METHODS: Bilingual nursing professionals performed translation and back-translation. Reliability and validity of the content and construction of the instrument were confirmed. Internal consistency reliability was determined. Construction and concurrent validity were verified using factor analysis and correlation coefficients. RESULTS: The total 14 items for the Korean version of the Nurses' Self-Concept Instrument (NSCI) were retained through item analysis. In explanatory factor analysis, four subcategories were proposed with their names of each factor: ‘Leadership’, ‘Staff relation’, ‘Knowledge’, and ‘Care’. The four factors accounted for 78.81% of the variances. The Cronbach's α regarding internal consistency were .77~.91 for the NSCI subscales. Correlation among four subcategories ranged .62~.84. CONCLUSION: The findings show that the Korean version of the Nurses' Self-Concept Instrument is reliable and valid for measuring professional Self-Concept of geriatric hospital nurses in Korea.
