Pragmatic AB Design
The Pragmatic AB Design is a single-case experimental design that collects repeated measurements of one individual or unit across two consecutive phases: a baseline phase (A) with no intervention, followed by an intervention phase (B). Deployed in real-world, clinically feasible conditions rather than tightly controlled laboratory settings, it is widely used in behavioral health, rehabilitation, education, and applied psychology to generate actionable evidence about individual-level treatment effects.
