Process Group Therapy
Process Group Therapy is a humanistic psychotherapy developed by Irvin Yalom in 1970. Its core mechanism: interpersonal learning through here-and-now group interaction: the group becomes a social microcosm where relational patterns emerge and can be examined and changed in real time. This catalogue links it to depression, personality disorders and relationship distress, typically in group format, long-term.

How Process Group Therapy works
Interpersonal learning through here-and-now group interaction: the group becomes a social microcosm where relational patterns emerge and can be examined and changed in real time
Ontology
Humans are fundamentally interpersonal beings; psychological distress often reflects distorted or impoverished relational patterns that developed in the family of origin
Therapeutic Voice
"What just happened between you two right now? Can we look at that together?"
View of the Person
The self is fundamentally relational: we become who we are through our patterns of connection with others. The group reveals these patterns and provides a laboratory for experimenting with new ways of being.

Moderate evidence base; strong clinical tradition
Burlingame et al. (2003); Yalom & Leszcz (2020)
One of the most widely taught group therapy models. Evidence base is mixed due to difficulty standardizing process-oriented groups for RCTs, but the therapeutic factors framework remains foundational.

Clinical cautions and blind spots
Assessment and precautions
Active psychosis, severe antisocial personality traits with predatory behavior, active substance intoxication, acute suicidality requiring individual safety management, clients whose presence would be harmful to other group members
Blind spots
Can be destabilizing for clients with severe personality pathology or active psychosis. The emphasis on interpersonal feedback may be harmful without sufficient group safety and therapist skill.
Philosophical roots
The social-microcosm premise comes from Harry Stack Sullivan's interpersonal theory: a person's characteristic relational distortions will reappear in any group they join, where they can be observed directly rather than reported. Yalom's existential psychology (Heidegger, Tillich, Rank) supplies the rest, including the existential factors among the therapeutic factors and the stance toward death, freedom, isolation, and meaning.
