สรุป	A rapid assessment instrument (RAI) is a short, standardized, self-report measure designed to be completed quickly and repeatedly so that a social worker can assess the magnitude of a client's problem, compare it against a validated clinical cutoff, and monitor change over the course of an intervention. The format was championed by Walter Hudson, whose Clinical Measurement Package scales set the template, and was systematized for practitioners by Springer, Abell, and Hudson, who laid out how to create and validate such instruments for practice and research.	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.
