McMillan Reference McMillan 2004 identified five defining characteristics of single-subject designs that rendered them an appropriate method for research within this field.

Despite their limited use single-subject research designs have significant methodological advantages over large-sample research designs that could be used to facilitate more rapid clinical research advances.

In design of experiments single-subject curriculum or single-case research design SCED is a research design most often used in applied fields of psychology education and human behavior in which the subject serves as hisher own control rather than using another individualgroup.

Some participants are assigned to a control group while others are in a treatment group. The same behavior is measured repeatedly. These designs provide a framework for a quantitative scientifically rigorous approach where each participant provides his or her own experimental control.

Between-Subjects Design Examples Pros Cons. First single-subject designs are focused on individual level and do not require populations. The basic argument is to establish an operator level to introduce the independent variable to focus on any change in the response.

Benefits of Single Subject Design Study low incidence populations and behaviors Cost effective Evaluate intervention prior to large scale study Flexible design is adaptable to situation Can be conducted in practice settings Test clinical hypotheses Monitor progress in applied settings Limitations of Single Subject Design.

Single subject research designs are weak when it comes to external validityStudies involving single-subject designs that show a particular treatment to be effective in changing behavior must rely on replicationacross individuals rather than groupsif such results are be found worthy of generalization Fraenkel Wallen 2006 p.
