OCD can be diagnosed by any of the professionals listed previously who have a master’s degree or higher, as long as they are licensed.
All of these individuals have received specific training in the diagnosis and treatment of mental disorders. Again, just be sure to check that the therapist is licensed in the state that you are in or is working under the supervision of someone who is licensed.
Licensure assures that the therapist has had a specific level of training. Depending on the training or educational degree, therapists are required to take specific exams to assure their basic competence.
These exams may be about specific treatments or disorders, basic knowledge of psychology, medication, or laws and ethics. Without passing these exams, a person cannot be licensed and therefore cannot practice without being under the supervision of someone who is licensed.
Having someone who is licensed either administer your care or supervise and sign off on the work of your treatment provider can help ensure that your treatment is appropriate.
