How to practice FAST
- Ask: what would I tell a friend to do here, to stay solid?
- **Fair** to yourself — what's your real position, not the polite version?
- **Don't over-apologize** — if you didn't do harm, don't pretend you did.
- **Stick to values + Truthful** — say what's true for you, even if it's not what they want.
Tracking FAST on a diary card
Whether a client used FAST — and whether it helped — is exactly what a DBT diary card captures. Recording skill use day by day is how you see, in session, whether interpersonal effectiveness skills are generalizing.
