Condition-specific assessments
Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.
Personality Disorders
Population and scope: One 33-year-old man described as having borderline personality disorder, receiving individual psychodrama with an auxiliary ego.
Limited evidence
The 2025 hermeneutic single-case study followed 54 sessions over 17 months. It reported improvements in distress, emotional regulation, work-related stress and substance use, with fluctuations. A single case cannot establish comparative efficacy, broad safety, or applicability to group psychodrama and other personality disorders.

How they work
Process Group Therapy
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
Psychodrama
Core mechanism: Enacting unresolved scenes on the psychodrama stage with group members as auxiliary egos allows emotional expression, new perspective (role reversal), and corrective experience in surplus reality
Ontology: Spontaneity and creativity are blocked by rigid role patterns (cultural conserves); suffering arises from relational role constrictions that limit flexible responding

What each assumes — and misses
Process Group Therapy
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.
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.
Therapeutic voice: What just happened between you two right now? Can we look at that together?
Psychodrama
Philosophical roots: Buber (I-Thou encounter, meeting); Bergson (élan vital, spontaneity, creative evolution); Aristotle (catharsis through drama); existentialism (action reveals being); theater traditions; Moreno was explicit about philosophy
Blind spots: Limited controlled research; high emotional intensity can overwhelm; requires skilled direction; cathartic model questioned by modern trauma theory; group format limits confidentiality
Therapeutic voice: Who would you like to say this to? Choose someone in the group to play that person. Show us the scene.
Choosing between them
Process Group Therapy (Humanistic) and Psychodrama (Expressive) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
