그룹코칭 프로그램이 중간관리자의 리더십역량 향상에 미치는 효과: 코칭리더십 역량과 긍정리더십 역량을 중심으로

The purpose of this study was to test the effectiveness of a group coaching program for improving team leaders’ leadership competency(coaching leadership competency and positive leadership competency) in organizations. For this purpose, we sampled 10 team leaders as an experimental group and 7 as a control group from "A" company in Seoul, and included 44 subordinates under the team leaders of the experimental group for objective measures of team leaders' leadership. The group coaching program was designed based on interviews with the executives of the company, literature research, and applied to the experimental group, which was divided into two sub-groups in consideration of the similarity of works and interactions. The program consisted of 8 sessions and 1 follow-up session. In this study, data were collected through a pretest, a posttest, and a follow-up test. The results showed that based on team members’ perceptions, generally team leaders' coaching and positive leadership significantly improved whereas team leaders’ perceptions of their leadership behaviors did not change significantly. Lastly, based on the results of this study, implications, limitations and suggestions for future research were discussed.
