“What type of psychotherapy is used for schizophrenia?”

This typically depends on the symptoms of treatment focus, level psychosis and/or delusional thought processes, intellectual abilities, presence of trauma, and any additional individual conditions which would impact a person's capacity to participate in treatment.

In my experience, psychotherapy isn't used for schizophrenia, but for people with schizophrenia. Having and living with that brain dysfunction is very challenging. It also doesn't exempt you from other psychological problems, like anxiety, aftereffects of trauma, and depression. The therapy may also address the importance of medication consistency, accepting and working with side effects, developing coping skills, finding meaningful activities, having some kind of social intimate relationships, and generally having someone to talk to who isn't judgmental.

There are a variety of psychotherapy approaches ranging from traditional psychoanalysis to cognitive behavioral therapy. It is important to talk to your provider to determine your goals and tailor the approach to goals.

While numerous types of psychotherapy, or talk-therapy, methods have been attempted, cognitive-behavioral therapy is used in most cases. In addition, group therapy is also helpful as another level of emotional support.
