Process Group Therapy

Irvin Yalom · 1970
Key text: The Theory and Practice of Group Psychotherapy (1970)
Existential-Humanistic Focus: Relational + Experiential Long-term Group

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

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.


Evidence

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.

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.

Contraindications

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
