Component analyses using single-subject experimental designs: a review.

A component analysis is a systematic assessment of 2 or more independent variables or components that comprise a treatment package. Component analyses are important for the analysis of behavior; however, previous research provides only cursory descriptions of the topic. Therefore, in this review the definition of component analysis is discussed, and a notation system for evaluating the experimental designs of component analyses is described. Thirty articles that included a component analysis were identified via a literature search. The majority of the studies successfully identified a necessary component; however, most of these studies did not evaluate the sufficiency of the necessary component. The notation system may be helpful in developing experimental designs that best suit the purpose of studies aimed at conducting component analyses of treatment packages.
