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.

An Overview on Current Quality Appraisal Tools for Single-Subject Experimental Designs
Single-subject experimental designs use participants (individuals or groups) as their own control and collect repeated measures of dependent variables over time to test the effects of a practice manipulated by the researcher.
