PurposeBased on a resulting typing model, this paper focuses on four types of leaders (Approachables on the sidelines, Distanced overseers, Realistic succeeders and Dedicated sensitives), who differ in the analytical core category of “development of awareness.”Design/methodology/approachInternal team coaching is intended to strengthen leaders in the health care system. The Team Leader Coaching Programme (TLCP) was implemented as an internal coaching instrument at rehabilitation centers using a train-the-trainer format. Twenty-one team leaders were surveyed on their experience of the coaching process they implemented in their teams. The interviews were analyzed using the grounded theory method (GTM) as theoretically discussed by representatives of second-generation GTM (Charmaz, 2014).FindingsUse of the TLCP proved to be an intervention for initiating and enhancing an awareness development process regarding team leaders' reflections on their own position and leadership role, regardless of their profession. This process was found to be a prerequisite for implementing the learned content. The typing model is discussed given current contextual conditions in the rehabilitation system and their connectivity in practice for integrating coaching elements into daily management.Originality/valueThis article presents a typology of healthcare leaders. Thanks to the reconstructive approach using grounded theory methodology, this article presents an in-depth analysis of the implementation process of a coaching program. The findings are both connectable to applied leadership research and useable for further development of training and interventions to strengthen team leaders in clinical settings.
