Integrative therapy refers to therapy in which elements from different types of therapy may be used. Therapists 'integrate' two or more therapeutic styles (e.g. Cognitive and Family Systems) to bring about a personalized and practical approach to healing.
Also known as Holistic Therapy.
Additionally, integrative therapy (with a small 'i') may also refer to the process of 'integrating' the personality by taking disowned or unresolved aspects of the self and making them part of a cohesive personality whole. It reduces the use of defense mechanisms that inhibit spontaneity and allows flexibility in solving emotional problems.
