Cognitive Behavioral Therapy Compared with Non-specialized Therapy for Alleviating the Effect of Auditory Hallucinations in People with Reoccurring Schizophrenia: A Systematic Review and Meta-analysis.
Cognitive behavioral therapy (CBT) is recommended as a psychological intervention for those diagnosed with schizophrenia. The prevalence of auditory hallucinations is high among this group, many of whom are cared for by community mental health teams that may not have easy access to qualified CBT practitioners. This systematic review examined the evidence for the superiority of CBT compared to non-specialized therapy in alleviating auditory hallucinations in community patients with schizophrenia. Two RCTs met the inclusion criteria totaling 105 participants. The Positive and Negative Syndrome Scale (PANSS)-Positive Scale was the outcome measure examined. A meta-analysis revealed a pooled mean difference of -0.86 [95 % CI -2.38, 0.65] in favor of CBT, although this did not reach statistical significance. This systematic review concluded there is no clinically significant difference in the reduction of positive symptoms of schizophrenia when treated by CBT compared to a non-specialized therapy for adults experiencing auditory hallucinations.
