सारांश	The Reliable Change Index (RCI) is a statistic that tells whether the change in an individual client's score on a measure, from before to after an intervention, is large enough that it is unlikely to be an artifact of the instrument's measurement error. Introduced by Neil Jacobson and Paula Truax in 1991 as one half of their two-part definition of clinically significant change, it converts a pre-post difference into a standardized value and compares it against a critical cutoff, typically 1.96, so that practitioners and researchers can classify each client as reliably improved, unchanged, or reliably deteriorated.	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.
