single-subject experimental design

single-subject experimental design

An experimental design involving the manipulation of an independent (treatment) variable across a pre-intervention baseline phase, an intervention phase, and commonly a post-intervention phase, thus offering repeated measures of the outcome over time and providing data regarding the effects of the introduction, continuation, alteration and withdrawal of treatment. Single-subject experimental design studies can involve more than one subject.
