Researchers within PABR are those who are involved in the whole research process from beginning to end and are responsible for the shape and progression of the process.

Co-researchers are invited to collaborate and join the research process for shorter or longer periods of time.

Participants are invited to join the research only at certain points, for instance during its public presentation, and are involved in different ways. In order to organise participation on equal terms, it is crucial to recognise and acknowledge the different questions, interests, responsibilities, capacities and availabilities of the different co-researchers and participants and to define their role within the process.
