Clarissa Schöller examines PR consulting in the context of communicator research and the professionalization debate within the field of public relations. She presents the interaction between PR consultants and their clients from the perspective of consulting theory concepts and summarizes it in a theoretical building block model. In a quantitative survey of PR consultants and clients, the author compares the perspectives of both groups on their interaction relationship and measures constructs such as power, understanding of success, and willingness to cooperate. From the data, she generates real types for clients and consultants that allow for a reference back to the theoretical foundation in the first part of the work.
