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
Therapeutic Voice
"Something just happened in the room. Did anyone else notice the shift when Maria said that?"
View of the Person
An interpersonal being whose patterns of relating — revealed in the group microcosm — are both the source of distress and the vehicle of change
Evidence
Group therapy included in multiple guidelines (NICE depression, anxiety)
Extensive research on group therapy generally; Burlingame meta-analyses
Burlingame et al. (2016) group therapy meta-analysis
The dominant model of process-oriented group therapy. Yalom's textbook is the standard. Therapeutic factors framework is widely used across group modalities. Existential orientation underlies the model.
