The International Association for Group Psychotherapy and Group Processes, IAGP, is a network of professionals engaged in the development and study of group psychotherapy and group processes applied to clinical practice, consulting, education, scientific research, and socio-cultural contexts. Our network provides opportunities to connect with others – professions, theories, and cultures – that are exploring the applications of group processes in small, medium, and large groups within clinical, organizational, and political contexts. IAGP is a truly international and global organization.

Founded in 1973, the International Association for Group Psychotherapy and Group Processes, IAGP is a worldwide network of professionals involved in the development of group psychotherapy and group processes, in the areas of theory, clinical practice, training, education research and consultancy.

On 12th August, 2003, the IAGP was incorporated in Switzerland, and on 10th October, 2003, it was granted the status of a Swiss tax-exempt charity (Reg. no. 409/2003).

In June 2006, the members voted to change the name of the IAGP from ‘The International Association of Group Psychotherapy’ to ‘The International Association for Group Psychotherapy and Group Processes.’ This was done to reflect the expansion of our members’ interests. Despite the name change, the acronym ‘IAGP’ will remain the same.

In addition to acting as an umbrella for its own affiliate organisations and running events with organisational partners throughout the world, the IAGP is seeking to further its mission through cooperation with carefully selected international umbrella organisations.
