APPI aims to advance Lacanian and Freudian psychoanalysis and psychotherapy as means and practice by which the individual may address the difficulties and questions that arise in his or her life, in relationships, and in the field of work.

The task that APPI undertakes is to provide and regulate the training of psychoanalysts and psychotherapists within a particular discipline based on the theories and tenets set out by Sigmund Freud and later by Jaques Lacan. This involves establishing structures so as to maintain the highest standards of training and of ethical practice, along with maintaining a register of suitably qualified psychotherapists and psychoanalysts. As a professional body, the responsibility of APPI also extends to establishing a Code of Ethics and Practice and maintaining Procedures in the Event of Complaint or Grievance.

In furtherance of the aim of advancing psychoanalysis, APPI also organises seminars and an Annual Congress and provides other structured forums through which members may continue their studies throughout their career. These events often involve eminent psychoanalysts and psychoanalytic psychotherapists from France, Spain, UK, Italy, USA and elsewhere coming to present their work in Ireland.

A.P.P.I. also publishes a bi-annual blind peer-reviewed Journal entitled ‘Lacunae – Lacanian Journal of Psychoanalysis’.
