“…The following summarizes foundational research on DBR instrumentation and procedures to emphasize how the defining features (i.e., direct, behavior, and rating) and guiding principles (i.e., defensible, flexible, repeatable, and efficient) provide direction for development and evaluation. Although future research is likely to yield support for alternate versions of DBR, this review emphasizes the development and evaluation of a singleitem scale DBR (SIS-DBR) approach rather than a multiitem scale DBR (MIS-DBR) approach (see Fabiano, Vujnovic, Naylor, Pariseau, & Robins, 2009). The SIS-DBR approach emphasizes the potential interpretation of ratings for individual items, which is distinct from multiitem scales that depend on summated ratings across multiple items.…”
