This qualitative study explores how roles are constructed within interprofessional health care teams. It focuses on elucidating the different types of role boundaries, the influences on role construction and the implications for professionals and patients. A comparative case study was conducted with two interprofessional primary health care teams. The data collection included a total of 26 interviews (13 with each team) and non-participant observations of team meetings (2-3 meetings at each site). Thematic analysis was used to analyze the data and a model was developed to represent the emergent findings. The role boundaries are organized around interprofessional interactions (autonomous-collaborative boundaries) and the distribution of tasks (interchangeable-differentiated boundaries). Salient influences are categorized as structural, interpersonal and individual dynamics. The implications of role construction include professional satisfaction and more favourable wait times for patients. The elements in this conceptual model may be transferable to other interprofessional primary health care teams. It may benefit these teams by raising awareness of the potential impact of various within-team influences on role construction.
