How they work
IPT
Core mechanism: Improving interpersonal functioning in one of four problem areas (grief, disputes, transitions, deficits) alleviates depression
Ontology: Depression occurs in an interpersonal context; improving relationships and social roles improves mood
Relational-Cultural Therapy
Core mechanism: Growth-fostering relationships characterized by mutual empathy counter isolation and internalized oppression
Ontology: Disconnection and isolation (often driven by social marginalization and power dynamics) are the source of suffering, not internal pathology

What each assumes — and misses
IPT
Philosophical roots: Sullivan (interpersonal psychiatry — personality is the pattern of interpersonal situations); Meyer (psychobiology); Durkheim (social integration and anomie); Bowlby (attachment/loss)
Blind spots: Focused scope (4 problem areas) may miss broader personality patterns; less suited for complex or chronic presentations
Therapeutic voice: It sounds like this grief hasn't had a place to go since your mother died. Let's make room for it here.
Relational-Cultural Therapy
Philosophical roots: Jean Baker Miller (relational model of development); Jordan (mutual empathy); Beauvoir (situated freedom); bell hooks (love as political practice); Fanon (internalized oppression); feminist standpoint epistemology
Blind spots: Very limited controlled research; political framing may not suit all contexts; less structured than manualized alternatives
Therapeutic voice: You've learned to keep people at a distance to protect yourself. What would it mean to let someone in here?
Choosing between them
IPT (Integrative) and Relational-Cultural Therapy (Social Justice) 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.
