I have a special interest in psychotherapy for psychosis. I have worked with patients with "schizophrenia", prodromal psychosis, bipolar disorder, psychotic depression and catatonia. This includes intensive psychotherapy. I have treated one patient with psychotic depression with 5x week psychodynamic psychotherapy. There is a tendency for psychiatrists to invoke the severe-end"rhetorical device and claim that psychiatric drugs work benefit those with the most severe illness. Actually this is a leap from the data which really show that the more severely ill someone is, the less anything works and the less of a placebo response there is and the less regression to the mean. It is not really that our drugs work better in the more severely ill patients. In my experience even hospitalized patients can benefit from psychotherapy that is supportive in nature. I do not find using explicit CBT interventions to be all that helpful and interpretations are not well tolerated by most patients though Elyn Saks in discussing her own illness calls them "detoxifying". Really psychotherapy helps with anxiety in psychosis, feelings of isolation, disconnection, and despair. I think these are worthy goals.
In contrast, in acute and transient psychotic disorder psychotherapy alone can be effective for the psychotic symptosm and I would avoid using medications if at all possible. I have successfully treated to 2 patients with brief psychotherapeutic intervention and no neuroleptics at all very early in the course of their psychotic attack. In prodromal psychosis/at-risk mental state there is data supporting the use of both supportive psychotherapy and CBT reducing the number of people becoming schizophrenic by 50%.
Most people don't have the stomach for working therapeutically with psychotic patients but there is certainly data that shows it can be helpful. The Chestnut Lodge studies show that for most schizophrenic patients expressive psychoanalytic treatment is not helpful but supportive psychoanalytic therapy is helpful. Carl Rogers did work with hospitalized psychotic patients in the 1950s and 60s and showed there was some benefit. R.D. Laing, Leon Redler, Morty Schatzman etc showed that you could indeed use psychotherapy and alternatives to hospitalization in frankly psychotic patients. Loren Mosher's Soteria House studies showed that psychotic patients who would end up hospitalized otherwise could be effectively treated by non-medically trained individuals without drugs or low-dose neuroleptics. Burn out is high however.
Working effectively therapeutically with psychotic patients is indeed possible but is it is labor-intensive, draining, with high potential for burn out, and highly dependent on the skill of the therapist and desire to work with such individuals. Most psychotherapists are not interesting in doing such work or find it too frightening. Winnicott's famous paper "hate in the counter-transference" largely refers to the hateful countertransference elicited by psychotic patients.
I have found my most satisfying and meaningful work to be in working therapeutically and deeply with psychotic individuals. my friends would argue I am a bit on the psychotic side myself, but I do not believe patients with psychosis cannot benefit from psychotherapy. If they have no insight, even better. If they are hospitalized, better still. I would also hasten to add some commentators have overstated the case for psychotherapy. I do not believe it is going to lead to cure of psychosis in the majority of cases but it can certainly help in other ways and help people live better with psychotic symptoms. At the same time, the medical model has failed people experiencing psychosis. We expose too many people to toxic neuroleptic drugs, too many drugs, at too high doses for too long. The prognosis for schizophrenia is no better than it was a 100 years ago. The US is one of the worst places in the world to become psychotic in terms of recovery. Our patients deserve better than what is the standard of care.
