Staff in the caring professions often have to contain troubling and unpredictable communications (projections) from those they work with. It is usual and expected for staff to have feelings in response to these communications – this is part of the process of emotional containment. If reflected on, the professional’s feelings and inner responses (countertransference) can be a vital source of information about the relational dynamics the service user carries with them and how the staff member is responding to these. However, if staff members do not reflect on and process their countertransference, there is the potential for increased stress for the staff member, and to inadvertently re-enact the patient’s relational difficulties rather than provide containment for them. A reflective practice (RP) group brings a whole clinical team together with the primary task being to reflect on and process staff-patient, teamm and organisational dynamics, to sustain caring relationships with patients and reduce the stresses of the work for staff. This chapter offers an introduction to psychodynamic RP groups, aimed at both participants and group facilitators. We discuss the theory of RP groups and their intended purpose, outline a process of starting a group, and consider what is expected for both participants and facilitators.
