Standardized Clinical Cutoff
The standardized clinical cutoff approach, developed by Jacobson and Truax, judges whether an individual client's change on a standardized measure is both statistically reliable and clinically meaningful. It pairs a Reliable Change Index — which asks whether a pre-to-post change is larger than the measurement error of the instrument — with a cutoff score that marks the boundary between the dysfunctional and functional (normal) populations. A client who moves reliably across that cutoff is counted as recovered, giving practice and research a defensible, individual-level definition of meaningful improvement.

Curated claims
Claims persisted in the evidence ledger, each with its own assessment.
This view does not invent a claim assessment when the ledger has none.
