สรุป	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.	Goal Attainment Scaling (GAS) is a method for measuring the outcomes of an individualized intervention by writing, in advance, a small set of client-specific goals and defining for each a graded scale of possible outcomes from much worse than expected to much better than expected. After the intervention, the actual outcome on each goal is scored on this scale and the scores are combined into a single standardized index, allowing idiosyncratic, personally meaningful goals to be aggregated and compared across clients and programs. It was introduced by Thomas Kiresuk and Robert Sherman in 1968 to evaluate community mental health programs.	A single-system design is a time-series approach to evaluating practice in which a single client system — an individual, family, group, or organization — is measured repeatedly on a clearly defined target before and during (and sometimes after) an intervention. By tracking the same system over time rather than comparing a treatment group to a control group, it lets a practitioner judge whether their own intervention is associated with change in the people they actually serve. It is the methodological backbone of the 'accountable professional' tradition codified by Bloom, Fischer, and Orme.
