ABSTRACT
This chapter focuses on the interventions that are classified on four levels of abstraction: epistemological and ethical, mandated, strategic, tactical/technical. Most people's epistemologies can be classified into three categories: common sense, scientific, and metaphysical. In psychotherapy, the term mandate means the power and the responsibility that clients hand over to the therapist, and vice versa. The therapeutic mandate consists of the expectations that the different actors of the therapeutic process bring with them, and of the constraints to which they are subjected. There are different types of mandates: official mandates and personal mandates. Following and joining the clients are two movements that are essential for establishing a circular mandate. The Bruges Model focuses on the therapeutic alliance, and the circularity of the mandates is essential. Communication science postulates that all communication implies a power relationship. This comes in two types: symmetrical and complementary.
