A Study on Double Mediating Effect of Organizational Culture & Empowerment on the Relationship between Transformational Leadership and Organizational Effectiveness perceived by Social Workers

The purpose of this study was to evaluate the double mediating effect of organizational culture and empowerment on the relationship between transformational leadership and organizational effectiveness perceived by social workers. A questionnaire survey was conducted from Aug. 1st to 30th, 2019 for 358 social workers working at social welfare centers located in Daegu City or Gyeongsangbuk-do. The data were analyzed using SPSS and AMOS. The results were as follows: First, the transformational leadership perceived by social workers was shown to have a positive (+) effect on organizational effectiveness. Second, organizational culture and empowerment were shown to have a double mediating effect on the relationship between transformational leadership and organizational effectiveness perceived by social workers. These results suggested that the establishment of philosophy and vision reflecting transformational leadership that pursues organizational change and innovation, and the creation of a flexible culture that allows the development of the social workers’ abilities and competencies are included in the methods to enhance the organizational effectiveness of social welfare centers. In addition, action plans are presented to delegate decision-making authority to social workers through decentralization of the organization and to guarantee their autonomy. Further studies investigating the organizational effectiveness under the classification of social welfare facilities according to the service delivery method and the presence of residential service provision are needed.
