What Is Clinical Evidence in Speech-Language Pathology? A Scoping Review.

Purpose: Two disparate models drive American speech-language pathologists' views of evidence-based practice (EBP): the American Speech-Language-Hearing Association's (2004a, 2004b) and Dollaghan's (2007). These models discuss evidence derived from clinical practice but differ in the terms used, the definitions, and discussions of its role. These concepts, which we unify as , are an important part of EBP but lack consistent terminology and clear definitions in the literature.
