본 연구는 상사의 변혁적 리더십이 부하의 역할행동, 조직시민행동 및 혁신행동에 미치는 영향과 함께 개인적 동일시와 사회적 동일시가 상사의 변혁적 리더십과 역할행동, 조직시민행동 및 혁신행동 사이의 관계를 매개하는지를 밝히고자 하였다. 연구 수행을 위한 자료는 11개 조직 300명의 직원을 대상으로 설문조사를 통해 수집하였고, 최종 분석에는 213명의 설문자료를 이용하였다. 연구결과, 상사의 변혁적 리더십은 개인적 동일시와 사회적 동일시에 정의 유의한 영향을 미치고 있으며, 변혁적 리더십은 역할행동, 조직시민행동 및 혁신행동 모두에 유의한 정의 영향을 미치고 있는 것으로 나타났다. 그리고 개인적 동일시와 사회적 동일시는 변혁적 리더십과 역할행동, 조직시민행동 및 혁신행동 간의 관계를 완전혹은 부분 매개하고 있는 것으로 나타났다. 하지만, 변혁적 리더십, 개인적 동일시, 사회적 동일시를 동시에 투입한 분석결과에서 사회적 동일시는 변혁적 리더십과 역할행동, 조직시민행동 및 혁신행동 간의 관계를 완전 혹은 부분 매개하고 있는 것으로 나타난 반면 개인적 동일시는 변혁적 리더십과 OCBO 간의 관계만을 매개하는 것으로 나타났다. 따라서 조직 전반에 대한 부하들의 긍정적인 행동을 이끌어 내기 위해서는 부하들로 하여금 사회적 동일시를 경험하게 만들어야 한다는 것을 제시하고 있다. 연구결과를 토대로 연구의 시사점과 한계점 및 향후 연구 과제를 제시하였다.
The purpose of this study is to examine the influence of a leader`s transformational leadership on follower`s in-role behavior, organizational citizenship behavior(OCB), and innovative behavior. In addition, we attempt to verify the mediating effect of social identification with the work unit and personal identification with the leader on the relationships between a leader`s transformational leadership and in-role behavior, OCB, and innovative behavior. While prior studies have usually tackled the relationship between transformational leadership and follower`s in-role behavior, OCB, and innovative behavior, they have rarely examined the mediating effects of social identification and personal identification on these relationships. Based on prior literature, this study derives following hypotheses. H1: Transformational leadership will be positively related to social identification of subordinates. H2: Transformational leadership will be positively related to personal identification of subordinates. H3: Transformational leadership will be positively related to in-role behavior of subordinates. H4: Transformational leadership will be positively related to OCB of subordinates. H5: Transformational leadership will be positively related to innovative behavior of subordinates. H6: Social identification will mediate the relationship between transformational leadership and in-role behavior, OCB, and innovative behavior. H7: Personal identification will mediate the relationship between transformational leadership and in-role behavior, OCB, and innovative behavior. To test the proposed hypotheses in our study, we collected data via a survey on data 300 employees in 11 organizations, and after excluding unanswered items questionnaires, total of 213 employees data is used for analysis. Hierarchical regression analysis is used to test the proposed hypotheses. Sobel test is used to test the significance of the mediating effects of social identification and personal identification. The major findings are as follows: First, as predicted, a leader`s transformational leadership were positively associated with social identification and personal identification. thus providing evidence that transformational leaders are likely to exert their influence on followers by affecting their feelings of identification. Second, transformational leadership is closely related to in-role behavior, OCB, and innovative behavior. Third, personal identification and social identification have turned out to have a full or partial mediation effect on the relationship between transformation leadership and in-role behavior, between transformation leadership and OCB, and between transformation leadership and innovative behavior. That is, this result indicated that a leader`s transformation leadership indirectly effects on in-role behavior, OCB, and innovative behavior through social identification and personal identification. Finally, however, when we entered transformational leadership, personal identification and social identification simultaneously into the equations, social identification fully or partially mediates the relationship between transformational leadership and in-role behavior, OCB and innovative behavior, whereas personal identification only mediates the relationship between transformational leadership and OCBO. Consistent with Kark, Shamir and Chen(2003), results also suggested that different mechanisms (personal or social identification) could, at least partially, account for these different outcomes (in-role behavior, organizational citizenship behavior, and innovative behavior of followers) of transformational leadership. Given the small number of samples, this study constitutes an exploratory attempt in nature. Caution must be exercised in attempting to interpret findings and to generalize the recommendations. The results proposed in this study must be validated by further research in diverse research settings. The results of this study are limited by its cross-sectional design and by the use of a single method of data collection. Causality could not be claimed due to the cross-sectional nature of the data. Longitudinal and experimental designs are needed to settle the dynamic relationships between transformation leadership and in-role behavior, organizational citizenship behavior, and innovative behavior. Additionally, although the hypothesized model was consistent with the data, there may be other, untested variables that might reflect a more complex process than is depicted in our model. For a comprehensive model of transformational leadership, future research must consider other variables, which may have complementary or substitute relationships with personal or social identification. Despite its limitations, the study has made several tentative contributions to the literature on transformational leadership in organizations. In general, the results of the study provide fairly strong support for the hypothesized relationships between transformational leadership, followers` identification with the leader and the organizational unit, in-role behavior, organizational citizenship behavior, and innovative behavior. Furthermore, support was also found for the hypothesized differential roles of personal and social identification in mediating the relationships between transformational leadership and followers` in-role behavior, organizational citizenship behavior, and innovative behavior.
