Pros for this therapy
Safety (in the sense of being very low risk) and the sense that a co-counseling session is a safe space is important to the methods. There are strict rules of confidentiality. In most circumstances, the counselor may not talk about a client's session without explicit and specific permission by the client. This is stricter than in other practices where practitioners discuss clients with supervisors, colleagues and sometimes with all sorts of other people. The peer relationship makes a considerable contribution to a sense of trust.
Cons for this therapy
May not be sufficient to treat organic mental illnesses such as MDD, GAD, or psychoses.
