1. Are you interested in "clinical practices" in general, that is, the set of all clinical practices?
2. Are you interested in only a small subset of "clinical practices?"
3. If you are interested in (2.), name and define that subset of clinical practices you are interested in, e.g., the clinical practice of medicine, the clinical practice of psychology, among others.
4. Are you interested in "clinical practices" of very different types that suggested by the examples in (3.).
Look to their school of training, recent CPD courses, and references to the method developed from theoretical frameworks in their clinician reporting/protocols.
