Abstract

Purpose
The aim of this study was to evaluate the validity and reliability of the short-version for clinical nurses on a communication competence scale developed to measure the communication competence of clinical nurses.
Methods
Data were collected from 396 clinical nurses who work at general hospitals in Korea. The original version of the Communication Ability Scale was shorted and content, construct, item-convergent/discriminant, convergent validity and also internal consistency and test-retest reliability were evaluated. Data were analyzed using exploratory and confirmatory factor analyses, Pearsons's correlation coefficient and Cronbach’s ⍺.
Results
As a result of item analysis and exploratory factor analysis, 5 subscales and a total of 20 items were derived. The confirmatory factor analysis showed adequate model fit indices (Normed x²=1.88, RMR=.04, RMSEA=.07, GFI=.87, CFI=.90, TLI=.87, IFI=.89). The items convergence and discrimination validity were verified using the Average Variance Extracted (.50~.56), composite reliability (.76~.86) and Φ±2SE (.42~.99). Convergent validity was demonstrated using Korean Version of Self-Efficacy Questionnaire (r=.59, p<.001). Internal consistency reliability and test-retest reliability were found to be acceptable, as indicated by a Cronbach’s ⍺ of .65~.79 and an intra-class correlation coefficient of .82~.90. The validity and reliability of the scale were verified.
Conclusion
The NACCS is a valid and reliable instrument for measuring communication competence for clinical nurses in Korea.
