Absolutely. There is no reason by regulation. Psychologists are regulated in our jurisdictions to deliver care. They can accept self-referrals. It is a requirement of some insurance programs and not others. It's a gatekeeping requirement. It's not a requirement that's at all tied to the scope of practice of the psychologist.
I agree with you. Not only does it create a barrier of access for the client or the patient, it also burdens the public health system, which is burdened enough.
