The Mediating Effects of Team Efficacy between Shared Leadership and Performance

Purpose - The Purpose of this study is to empirically examine the direct effect of the shared leadership on the performance variables, and the mediating role of team efficacy between shared leadership and performances. The result variables were set as organizational performance and financial performance and set as team efficacy as a mediator. In addition, a group with high team efficacy will have a positive effect on various organizational performance. Based on these existing studies, we set hypotheses and demonstrate them positively. Research, design, data and methodology - We hypothesized as follows H1. Shared leadership I s positively related to performance through review previous studies. H2. Group efficacy mediates the positive relationship between shared leadership and performance. To verify the research hypothesis, the study collected a survey targeting 522 employees that is 3 employees each from 174 branches of a financial company. The proportion of males and females was 48.9% and 51.1%, respectively. The distribution of age was 42% in their 30s, 30.7% in their 40s, and 21.6% in their 20s. Finally, the number of years was the highest at 28.0% for less than 5 years. It was considered that measurement items used in this study had reliability. We measured shared leadership with instrument made by Hiller et al.(2006). Group efficacy was measured by questionnaire created by Guzzo, Yost, Campbell, and Shea(1993). Performance variables were measured by 2 items. Results - All variables showed a statistically significant correlation in terms of their relevance. The hypotheses were verified through multiple regression analysis. Conclusions - In the result on the influence of shared leadership, it showed that shared leadership had a positive correlation with team efficacy. It was also indicated that shared leadership had a positive impact on organizational performance and perceived financial performance. In the results of a mediating effect of team efficacy, it was indicated that in a relationship between shared leadership and organizational performance, and there was a mediating effect of team efficacy between shared leadership and perceived financial performance. Based on these findings, theoretical and empirical implications were discussed in details and the limitations and future direction of the study were suggested.
