What it is

Integrative Therapy (IT; German Integrative Therapie) is a broad framework for psychotherapy that works across schools (schulenübergreifend), not one single technique. Hilarion Petzold developed it from the mid-1960s with Johanna Sieper and Ilse Orth. It is taught at the Fritz Perls Institut (FPI)…

Format

• Structure of the approach. IT has no fixed session-by-session protocol. Instead the therapist works with a set of nested frameworks: a process model (the tetradic system), a diagnostic model (IPD plus ongoing process diagnosis), a choice of modalities, styles and settings, the four ways of healing,…
• Scope: the four phases are commonly applied to a single session, to a sequence of sessions, and to the whole course of therapy.

Who practises it, and how they are trained or regulated

• Übungszentriert-funktional (exercise-centred, functional): training skills, relaxation, movement. Use for deficits and symptom management.
• Levels of depth (Ebenen der Tiefung). These are a named component. The usual four-level form is: (1) reflection; (2) images, memories and affects; (3) involvement, meaning partial regression and intense emotional re-experiencing; (4) autonomous bodily reactions, meaning deep regression with vegetative responses. The therapist chooses and regulates depth on purpose.

Evidence status, as the guide reports it

• The theory is organised as a "Tree of Science": metatheory (philosophy, anthropology), realexplicative theories (personality, development, health and illness), and praxeology (process, intervention and method theory). The core idea of change runs as follows. The person is an embodied subject…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• How do you and the practitioner understand what is happening, in spiritual or cultural terms? Is that a source of comfort, worry, or both?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• spreading thin across all factors. Prioritise by the IPD.
• relaxation-induced anxiety. Offer eyes-open and movement-based options.
• the therapist imposing their own political views. The patient's values lead.
• confidentiality outdoors, physical limits, allergies, animal-safety training.
• overwhelming re-enactment. Use puppets or a distanced observer position for fragile patients.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
