Three theses are developed in this article. First, although they share the common goal of striving toward the best intervention services possible, clinical practice and experimental intervention research are different in fundamental and practically significant ways. Second, nonexperimental research, some of which can be implemented by clinicians, provides an essential bridge between experimental investigation and clinical application. Third, professional and academic bodies governing speech-language pathology must take steps to ensure that speech-language professionals in research and clinical practice work in a complementary manner to develop and test the most effective intervention methods possible.
