Integrating measurement of control and affiliation in studies of physician-patient interaction: the interpersonal circumplex.
Following a brief overview and commentary on the physician-patient communication literature, this article summarizes and evaluates research on the relationship between physician-patient control (dominant-submissive) and affiliation (friendly hostile) behaviors as they relate to medical outcomes. Findings for both verbal and nonverbal control and affiliation measures are included. The interpersonal circumplex (together with the important interactional principles that it incorporates) is then introduced as an heuristic guide for future medical interaction research. The circumplex was constructed as a conceptual and empirical model to integrate the numerous studies that have established control and affiliation as universal dimensions of human interpersonal behavior and relationships. Next, the small group of studies that have applied circumplex inventories to analyses of practitioner-patient transactions are reviewed with emphasis on their strengths and unique aspects of their findings. The concluding section enumerates advantages and innovations that the interpersonal circumplex and its measures can provide to facilitate more heuristic studies of physician-patient interactions.
