摘要	A self-anchored rating scale (SARS) is an individualized measurement tool in which a client rates a personally relevant target — a feeling, thought, or behavior that may not be captured by any standardized instrument — on a fixed numeric scale whose points the client and worker have anchored in advance with concrete, individually meaningful descriptions. Widely taught in social-work practice evaluation through Bloom, Fischer, and Orme's work, it lets a worker measure highly idiosyncratic internal states repeatedly and reliably, supplying the data for single-system designs when no off-the-shelf scale fits.	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.
