To understand how tensions caused by the multidisciplinary nature of executive coaching are perceived and overcome, this modified ethnographic study was conducted at an executive coaching program and leadership center at a prestigious European business school. This study is built on prolonged discussions on the role of psychology in executive coaching (mostly in America). According to Ozkan (2008), tribal conflicts between psychologist-coaches and non-psychologist-coaches exist, and debates continue concerning qualification and formal training. In this context, many coach preparation programs have entered the academic community with collaboration from experts of various disciplines (Starr, 2008). This study examines how psychology and organizational study are incorporated in a coaching program for coaches, using an integrated model, within an academic setting. The integration of psychology and organizational studies is thought to be a great success among study participants, and, after a decade, the structured business school recently approved their executive master's degree in clinical organizational psychology, a new discipline incorporating clinical psychology and organizational studies, for the program. Tensions are found only in the past and outside of the program in: (1) a past failure with psychologists and a continuing success with business people, (2) personal careers of multidisciplinary faculty members, (3) practical and disciplinary conflicts with other parts of school. The tensions are mostly overcome, and the tribal conflict was not found since faculty members and most coaches have both identities. Successful management of tension is attributed to leadership and organizational culture of the program. Thematic analysis is used for data analysis. Conclusions include: (1) fits between training targets and program orientation should be considered in coach preparation, and (2) business-oriented mind would help integrate multiple disciplines in executive coaching. Follow-up studies are recommended after the degree program is offered and after the founder's retirement. [The dissertation citations contained here are published with the permission of ProQuest LLC.
