There is no national standard for certification of competence in Cognitive Behavioral Therapy (CBT). Patients and families can find this frustrating. The Beck Institute is developing a certification for release in 2019, but it is not clear how this will impact the field. Expertise with CBT is important for many issues like anxiety and depression, and new literature indicates its applicability in treatment of psychosis. California is among the first states to implement this efficacious and well-researched treatment model.
Be clear with people if CBT is a skill set you have and what your practice history is with this technique. CBT is not for every patient, every problem or every practitioner. If you are not trained in this modality, be transparent so that the person seeking CBT can locate the appropriate intervention.
