CBT does not improve relapse rates in people with recently relapsed psychosis

Secondary outcomes: psychotic symptom measures (PANSS); delusions (Psychotic Symptom Rating Scale (PSYRATS)); hallucinations (PSYRATS); depression (Beck Depression Inventory Second Edition (BDI-II)); and social functioning (SOFAS score). The limitations of CBT are most clearly evident in individual CBT in which well trained and experienced therapists were judged to have delivered competent therapy that adhered to the treatment manual. [...]although individual CBT for persistent psychotic symptoms when added to medication may confer some modest benefits in reducing emotional distress, 2 and should continue to be offered, it is not efficacious in preventing further relapse among those recovering from a recent relapse.
