Purpose & objective.
Phase 1 builds the stability that makes Phase 2 possible. Without it, processing trauma is at best impossible and at worst retraumatizing.
That stability is concrete: internal and external safety, regulation skills the client can use with or without you in the room, internal resources strong enough to hold them through the memory, and an alliance solid enough that they'll tell you when they're losing ground. The capacity that gates processing is dual awareness ~ the client can stay in contact with you and the present room while also making contact with the traumatic material. When that capacity isn't there, the client doesn't process the memory ~ they relive it.
Across this site, Phase 1 / Phase 2 / Phase 3 refers to Herman's tri-phasic model. Inside Herman's Phase 1, Shapiro's History-Taking (Phase 1) and Preparation (Phase 2) do their preparatory work. See the Stabilization page for the full framework map.
Skills-building and therapeutic alliance.
Phase 1 is two tracks running at once: skills-building and the therapeutic alliance. Neither is sufficient alone. A client with skills and no relationship will not bring you the material that needs working. A client with relationship and no skills will be flooded the moment you do.
Skills-building is the regulation, distress-tolerance, and dual-awareness curriculum the client can carry out of the room ~ the floor under everything Phase 2 will ask of them. DBT is the canonical, well-tested version of this curriculum (see below); other regulation work, somatic anchors, parts language, and resourcing all belong here too. The full toolkit is on the Stabilization page.
Therapeutic alliance is the relationship robust enough that the client will tell you when they're losing ground, take a corrective when you misattune, and keep showing up across rupture and repair. For trauma clients with attachment injury, the alliance is a treatment ingredient, not a precondition for one.
What clinicians skip ~ and what it costs.
The most common Phase 1 errors are time errors: insufficient time spent on resourcing, insufficient time spent screening, insufficient time spent on the alliance. Often these errors are pressured by external constraints (managed care, training expectations, productivity targets). They are still errors.
Pre-treatment screenings ~ DES-II, ITQ, sensitivity, and attachment ~ are on the Screenings page with downloadable PDFs. The cost of not screening is iatrogenic destabilization that can take months to repair. The math is not close.
Do not begin Phase 2 if…
…the client cannot reliably exit a difficult emotional state with a tool you have practiced together. …the client has unscreened or active dissociation. …the alliance is fragile. …life circumstances make destabilization dangerous (active SUD relapse risk, unsafe housing, ongoing abuse). When in doubt, stay in Phase 1 longer.
DBT is all Phase 1.
DBT is Marsha Linehan's modality ~ CBT plus mindfulness. The DBT skills package is, functionally, a stabilization curriculum: distress tolerance, emotion regulation, interpersonal effectiveness, and mindfulness. All four sit inside Phase 1.
If you are EMDR-trained and your client has DBT skills already on board, you have a Phase 1 head start. If they don't, the DBT skills modules are a clean, well-tested way to build what Phase 1 requires before you go anywhere near Phase 2.
The four DBT skills modules ~ as Phase 1 stabilization
- Mindfulness. Present-moment attention; observing without merging. The dual-awareness substrate everything else rests on.
- Distress tolerance. Surviving a wave without making it worse. Crisis-survival skills that keep clients out of behaviors that re-traumatize them.
- Emotion regulation. Naming, modulating, and acting opposite when indicated. Builds the regulation Phase 2 will demand.
- Interpersonal effectiveness. Asking, refusing, repairing, leaving. The relational floor under stable therapy and stable life.
Linehan named the goal of the work creating a life worth living ~ a phrase that maps onto Herman's Phase 3 (Reconnection). DBT, however, lives in Phase 1: it builds the conditions that make Phase 2 possible and Phase 3 reachable.
Reconnection work starts here ~ not in Phase 3.
This is my clinical position, and I want it stated plainly: I do not move a client from Phase 1 to Phase 2 until the relational work usually filed under Herman's Phase 3 (Reconnection) is already underway. Two reconnection tasks in particular belong in Phase 1 and, in my work, gate the move to processing:
- Tracking attachment patterns as they show up in current relationships, not only in history. How the client does closeness, conflict, and rupture now ~ with you, with the people in their life ~ is data you need before you open memory, not after.
- Naming and rehearsing relational risks ~ disclosure, repair, boundary-setting, exit ~ in a measured way. The client who cannot yet disclose, repair a rupture, set a boundary, or leave a situation safely has no relational floor to stand on once processing destabilizes them.
Why this gates Phase 2
Deferring this work to a post-processing “Phase 3” is backward. The client with no current-relationship tracking and no rehearsed way to handle disclosure, rupture, or exit is precisely the client most likely to destabilize when memory work opens. Build the relational floor first. See the full reconnection stage on Phase 3.
When to stay in Phase 1.
When in doubt, stay. Stabilization is not a phase you finish; it's a foundation you keep returning to. Many clients live primarily in Phase 1 for months and that is appropriate work. The pressure to "get to processing" is a clinician problem, not a client problem.
The client who needs Phase 2 most is the client who can least afford to leave Phase 1 early.
