Interprofessional collaboration has been described both as an opportunity to meet the demands of a complex society, but also as a potential threat to professional autonomy. Interprofessional relationships are central in collaborative efforts, and there is a need to investigate the psychosocial processes involved. In the present study, we have investigated how professionals in a collaborative effort perceive collaboration, and how these perceptions are organized. We have used an adaptation of the Perception of Interprofessional Collaboration Model Questionnaire—PINCOM-Q—to develop and test a model of collaboration perceptions in a sample of professionals working within local crime prevention at the community level. Using a confirmatory factor analysis approach, we have found support for a three-dimensional conceptualisation of how interprofessional collaboration is perceived. We have labelled the dimensions in the model as follows: Group Climate, Influence, and Personal Motivation. Our results implicate that the development of interprofessional collaboration should emphasize supportive group communication, an equal distribution of group influence, and finally, a personal value outcome gained from participating in the collaboration.
