Grief & Loss

What each assumes — and misses

CBT

Philosophical roots: Epictetus, Marcus Aurelius (Stoic appraisal theory — it is not things that disturb us but our judgments); Kant (rational autonomy); Popper (falsifiability as therapeutic method); Ellis cited Stoics explicitly

Blind spots: May underemphasize attachment history, relational dynamics, and the therapeutic relationship itself as mechanism of change

Therapeutic voice: What evidence do you have for the thought that nobody cares about you?

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.

Choosing between them

CBT (Cognitive-Behavioral) and IPT (Integrative) 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.
