Interpersonal Therapy (IPT) addresses cluster b through its strong evidence base: most cluster b is connected to relationship problems, and improving relationships improves cluster b.
The Four IPT Focus Areas for Cluster B
IPT targets one of four interpersonal problem areas that typically accompany cluster b:
- Grief: Loss and bereavement contributing to cluster b
- Role disputes: Conflicts in important relationships driving cluster b
- Role transitions: Life changes creating adjustment-related cluster b
- Interpersonal deficits: Limited social skills or relationships sustaining cluster b
IPT vs. CBT for Cluster B
While CBT targets thoughts and behaviors, IPT targets relationships and communication. Both are highly effective for cluster b — the best choice depends on the primary driver.
What IPT for Cluster B Looks Like
IPT for cluster b typically runs 12-20 sessions, with early sessions identifying the interpersonal focus area, middle sessions working on it, and later sessions consolidating gains.
