Purpose
This study aimed to identify the effects of shared leadership, communication skills, and team effectiveness, as perceived by nurses and nursing assistants in comprehensive nursing service units.
Methods
A cross-sectional research design was adopted, and the sample included 306 nurses, nurse assistants, and caregivers working in nine hospitals with fewer than 500 beds in two South Korean cities. The data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson’s correlation coefficient, and four-step hierarchical regression analysis.
Results
The factors influencing team effectiveness in the hierarchal multiple regression analysis were shared leadership (β=.57, p<.001) and communication skills (β=.18, p<.001). These factors explained 49% of the total variance.
Conclusion
To enhance team effectiveness in compressive nursing service units, educational programs focusing on shared leadership and communication skills among nurses, nursing assistants, and caregivers must be developed.

PURPOSE
The purpose of this study was to develop a Team Effectiveness Scale for Nursing Units (TES-NU) and verify validity and reliability of the developed scale.
METHODS
A preliminary 69 item version of the TES-NU was developed through in-depth interviews. The draft scale was developed using 65 items selected following content validity evaluation. Finally, thirty items with response options on a 5-point Likert scale were selected based on internal consistency reliability and construct validity. Subsequently, convergent validity of the TES-NU was verified.
RESULTS
Six factors, namely, leadership of the head nurse, cohesion, job satisfaction, competency of nurses, productivity, and coordination were identified. These factors explained 64.6% of the total variance. The TES-NU's Cronbach's α for the total scale was .94. The correlation coefficient between the scores of the TES-NU and Ahn's Team Effectiveness scale was .59.
CONCLUSION
Results show that the TES-NU developed in this study has good reliability and validity. Therefore, this TES-NU is recommended as a useful tool for managing team effectiveness for nursing units.
