Co-therapy or conjoint therapy is a kind of psychotherapy conducted with more than one therapist present.[1][2] This kind of therapy is especially applied during couple therapy.[3][4][5]Carl Whitaker and Virginia Satir are credited as the founders of co-therapy.[6][7] Co-therapy dates back to the early twentieth century in Vienna, where psychoanalytic practices were first taking place.[8] It was originally named "multiple therapy" by Alfred Alder, and later introduced separately as "co-therapy" in the 1940s.[9] Co-therapy began with two therapists of differing abilities, one essentially learning from the other, and providing the opportunity to hear feedback on their work.
