In the recent years, Single-Case Experimental Design (SCED), which has for long been used in various fields of psychology as a design to evaluate the effects of psychosocial interventions, has received renewed attention. This paper discusses the reasons for the renewed interest in SCED by reevaluating the level of evidence and the development of research methods. Then, I focused on using the index based on the non-overlap rate as a statistical analysis method and explained the calculation method. Specifically, the calculation methods of PND, PEM, IRD, NAP, and Tau-U are explained. The criteria for interpreting the measures are also explained.
