概要	The evidence-based practice (EBP) process is a structured, five-step way of making practice decisions by integrating the best available research evidence with professional expertise and the client's values and circumstances. Originating in evidence-based medicine as defined by Sackett and colleagues and translated into social work by Eileen Gambrill and others, it reframes EBP not as a fixed list of approved programs but as a transparent decision process — ask, acquire, appraise, apply, assess — that an individual practitioner carries out with and for a particular client.	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.
