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