Use this background section to understand when the tool fits, how practitioners use it, and what to consider before sharing it with clients.

When It Is Used

Use it during relapse-prevention work when a client can discuss a recent use, near-use, or high-risk pathway and the practitioner wants the sequence to guide follow-up.

What It Does Not Do

It does not calculate relapse risk, assign diagnoses, generate clinical conclusions, or create a full relapse-prevention plan unless those details are entered by the practitioner and client.

Does this tool produce a score?

No. It produces a chain formulation, not a questionnaire score or relapse-risk level.

Can a partial chain be saved?

Yes. Unknown or unresolved links can remain blank and the chain is shown as incomplete.

Is there a separate client-only version?

No separate independent client experience is required. The supported mode is practitioner and client completing the chain together.
