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
Supportive Psychotherapy
Core mechanism: Strengthening adaptive defenses, reinforcing reality testing, and providing a stable therapeutic relationship supports ego functioning
Ontology: Vulnerability in ego functioning requiring support rather than uncovering; defenses need strengthening, not interpretation

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.
Supportive Psychotherapy
Philosophical roots: Ego psychology (Hartmann — autonomous ego functions); Winnicott (holding); common factors tradition (Wampold); pragmatic eclecticism
Blind spots: May maintain status quo rather than promote growth; can be used as excuse to avoid learning structured treatments
Therapeutic voice: You've been through an incredibly difficult week, and you're still here. That matters.
Choosing between them
IPT (Integrative) and Supportive Psychotherapy (Psychoanalytic) 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.
