A.P.P.I. is a professional membership organisation comprised of members whose clinical work is based upon the practice of psychoanalysis and/or psychoanalytic psychotherapy.

Membership of the organisation is open to those whose practice work is in conformity with the code of ethics and practice of the organisation. Membership categories, academic qualifications and application deadlines can be found on the Membership page.

All psychoanalytically-informed theories and therapies (some of them also called psychodynamic) are based on the work of Sigmund Freud.
