- Depression in adults: treatment and management (NG222)
Discussed in the source
NICE includes group CBT, behavioral activation and related structured approaches. Group format alone does not establish a recommendation for interpersonal process group therapy.
Scope: Specific structured group interventions for adult depression.
- Generalised anxiety disorder and panic disorder in adults (CG113)
Discussed in the source
NICE’s group option is a defined CBT-based intervention. It should not be treated as a recommendation for any process-oriented therapy delivered in a group.
Scope: CBT-based psychoeducational groups for adults with GAD at step 2.

The guideline discusses psychodrama among expressive adjuncts within structured treatment. This is expert practice guidance, not a separately graded recommendation for other conditions.
Scope: Adults with dissociative identity disorder or closely related dissociative presentations.

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
Interpersonal Process Group Therapy
Core mechanism: The group becomes a social microcosm where interpersonal patterns emerge in the here-and-now; feedback, cohesion, and corrective emotional experience produce interpersonal learning
Ontology: Psychopathology is fundamentally interpersonal: distorted patterns of relating are both the cause and consequence of suffering, and the group reveals them in real time
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
Interpersonal Process Group Therapy
Philosophical roots: Sullivan (interpersonal psychiatry); Buber (I-Thou encounter in group); existentialism (Yalom: ultimate concerns); Rogers (encounter group tradition); Lewin (group dynamics, field theory)
Blind spots: Requires skilled facilitation; group composition can determine outcomes more than technique; here-and-now focus may frustrate members wanting symptom relief; less suited for acute conditions
Therapeutic voice: Something just happened in the room. Did anyone else notice the shift when Maria said that?
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
Interpersonal 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.
