Schizophrenia | Bulimia Nervosa | Personality Disorders
CBT has only been studied as an adjunctive treatment to pharmacotherapy
for schizophrenia. Gould et al. (2001) conducted a
meta-analysis of the effects of cognitive therapy (combined with
pharmacotherapy) on decreasing psychotic symptoms (hallucinations
and delusions) and modifying core dysfunctional beliefs in patients
with schizophrenia, schizoaffective disorder, or delusional disorder.
They found large acute treatment effects for cognitive therapy across seven
controlled studies, and these effects were maintained, and even
increased in some cases, over time. When compared with a control
condition (waiting list, TAU, or psychological placebo), cognitive
therapy was superior in five of the seven studies, but no significant
differences between cognitive therapy and control conditions were
seen in two of these studies.
