Single-Case Experimental Designs to Evaluate Novel Technology-Based Health Interventions

Single-Case Experimental Designs to Evaluate Novel Technology-Based Health Interventions

First, single-case does not mean “n of 1”. The number of participants in a typical study is always more than 1, usually around 6 but sometimes as many as 20, 40, or more participants [11,22]. Also, the unit of analysis, or “case”, could be individual participants, clinics, group homes, hospitals, or health care agencies. Given that the unit of analysis is each case, a single study could be conceptualized as a series of single-case experiments.
