EAP 2009 Definition of Psychotherapy 
- The exercise of psychotherapy shall be the comprehensive deliberate and planned treatment or therapeutic intervention on the basis of a general and special training of disturbances of behaviour and states of disordered condition, or wider personal developmental need, connected with psycho-social and also psychosomatic factors and causes, by means of scientific psychotherapeutic methods, in an interaction between one or several treated persons, and one or several psychotherapists, with the objective of mitigating or eliminating the established symptoms, to change disturbed patterns of behaviour and attitudes, and to promote a process of maturing, development, sanity and well-being in the treated person.
- The independent exercise of psychotherapy shall consist in the practical implementation, at the therapist's sole responsibility, of the activities described in paragraph 1, irrespective of whether the activities are exercised on a self-employed basis or in the framework of an employment relationship.
