Single Subject Research Design

Single subject research design refers to a unique type of research methodology that facilitates intervention evaluation through an individual case. Single subject research design is a type of research methodology characterized by repeated assessment of a particular phenomenon often a behavior over time and is generally used to evaluate interventions [ 2 ]. Repeated measurement across time differentiates single subject research design from case studies and group designs, as it facilitates the examination of client change in response to an intervention. Although the use of single subject research design has generally been limited to research, it is also appropriate and useful in applied practice. Single subject research designs differ in structure and purpose and typically fall into one of three categories: within-series designs, between-series designs and Skip to main content Skip to table of contents.

This research design is useful when the researcher is attempting to change the behavior of an individual or a small group of individuals and wishes to document that change. Unlike true experiments where the researcher randomly assigns participants to a control and treatment group, in single subject research the participant serves as both the control and treatment group. The researcher uses line graphs to show the effects of a particular intervention or treatment. An important factor of single subject research is that only one variable is changed at a time.
