This study design is typical of a single-case experimental design. This design involves observing a single subject or small group of subjects over time, with repeated measures taken at various points. In this specific design, the subject is observed for several weeks with no treatment (baseline), followed by a treatment phase, a withdrawal phase, and a second treatment phase. This allows for the examination of the effects of the treatment and the withdrawal of treatment, as well as the potential for comparing the effects of the first and second treatments.
