Transcending Therapy Models and Managing Complexity: Suggestions from Integrative Systemic Therapy.

Integrative Systemic Therapy (IST) is a metatheoretical perspective for the conduct of individual, couple, and family therapy. Following a brief description of IST, this article presents developments in IST and their implication for psychotherapy integration. The nature of problem solving in IST is clarified, and the relationship between IST's essential problem-solving tasks and its core decision-making process is defined. Particular attention is paid to two dimensions of IST that have given it its name: integration and systems theory. The advantages of a therapy that is client system-centered and not model-driven are discussed, and a justification for "good enough" execution of interventions abstracted from specific models is provided. A procedure for balancing pragmatic demands of therapy with a commitment to account, as needed, for broader or deeper systemic issues is presented.
