Treatment Integrity in Single-Subject Research


The empirical demonstration that changes in behavior are functionally related to manipulated changes in the environment is a fundamental principle of behavior analytic research (Baer, Wolf, & Risley, 1968). In other words, researchers must demonstrate that changes in a dependent variable are functionally related to systematic, controlled, and measur­ able changes in an independent variable. This demonstration requires the representation of the independent variable by known physical pa­ rameters of an environmental event. Without clear and unambiguous specification of the independent variable, there can be no definitive conclusions regarding a functional analysis of behavior (Johnston & Pennypacker, 1980; Sidman, 1960).
