Internal Family Systems (IFS)

preliminary evidence

Listed on SAMHSA's evidence-based registry, with a 2017 randomized trial and several pilot studies; a 2025 review found depression is the indication with the most repeated positive results, while larger trials are still needed.

Who it tends to fit
People drawn to working with their inner conflict as 'parts' — the self-critic, the protector, the wounded younger one — rather than as symptoms.
Who it may not fit
Anyone wanting a purely body-based approach, or in need of acute clinical care.
Cost & access
$100–250 per session; many IFS practitioners are also licensed therapists, but the IFS directory lists trained practitioners who may not be — check.
Credentials
Certified, but not necessarily licensed — check both

Internal Family Systems, developed by Richard Schwartz, works from the idea that the mind is naturally made of “parts” — and that underneath them all is a calm, curious core it calls the Self. The parts aren’t problems to remove; they’re seen as protectors doing their best, often stuck in the role they took on during a hard time.

In practice, you turn toward a part with curiosity instead of judgment — the anxious planner, the harsh critic, the one that numbs out — and get to know what it’s afraid would happen if it stopped. A lot of people find it a gentler, less shaming way to meet the stuff they’d usually fight with themselves about.

It’s mostly talk-based, though it pairs naturally with body awareness.
