Meta-analyses examining the efficacy of psychological treatments for schizophrenia revealed a beneficial effect of CBT on positive symptoms (i.e., delusions and/or hallucinations) of schizophrenia (Gould et al., 2001; Rector & Beck, 2001). There was also evidence (Zimmerman et al., 2005) that CBT is a particularly promising adjunct to pharmacotherapy for schizophrenia patients who suffer from an acute episode of psychosis rather than a more chronic condition.
