Review Comparative StudySingle case studies in psychology and psychiatry.
Single-case experimental designs are presented and discussed from several points of view: Historical antecedents, assessment of the dependent variable, internal and external validity and pre-experimental vs experimental single-case designs. In addition, general characteristics of experimental single-case designs are presented along with examples of the most common design types. ⋯ It is argued that single-case experimental designs are well suited for medical research as well as clinical practice. They provide tools for testing causal hypotheses concerning the effects of interventions in the single case.
