The alternating treatments design is the single-subject research design that manipulates multiple treatments one at a time, to determine their effect. This design involves rapidly alternating between two (or more) treatments while measuring the effect on the behavior of the individual. This allows for comparisons to be made between different treatments and for the identification of which treatment is most effective for a particular behavior.
