Schizophrenia is a heterogeneous disorder that affects behavioral, affective, and cognitive domains and consists of positive and negative psychotic symptoms. Antipsychotic therapy is the first-line treatment for schizophrenia. However, treatment adherence levels are low. Even if there is good treatment compliance, residual symptoms and treatment resistance can be seen. As a result, recent schizophrenia treatment guidelines suggest Cognitive Behavioral Therapy (CBT) as adjunctive to antipsychotic therapy. CBT is known effective, especially on positive symptoms. This paper aims to review CBT practices and their effectiveness in schizophrenia.
