Abstract
Objective: There is evidence from the literature that Cognitive Behavioral
Therapy for psychosis (CBTp) might have a positive effect on depressive
symptoms. The aim of this paper is to examine how treatment using CBTp for
patients experiencing psychosis effects depressive symptoms associated with
schizophrenia.
Methods: 17 trials of CBTp that reported depressive symptoms were
selected for this literature review.
Results: Six out of 17 trials reported beneits for the depressive symptoms.
In 3 of these trials CBT for anxiety and low self esteem was used that did not
target psychotic symptoms as primary targets. In two trials effects on depression
became statistically signiicant at followup only.
Conclusion: CBTp can reduce depressive symptoms in patients with
schizophrenia. However, there is a need for improving reporting of these
symptoms in future studies.

in the UK and the United States [6-8]. here is evidence from meta
analyses too, that it is efective; for example [3]. his review reported
overall beneicial efects of the target symptom 0.40 (95% CI= 0.252,
0.548) from 33 studies. he same meta analysis reported an efect size
of 0.363 [95% CI=0.079, 0.647] for its efect on depressive symptoms,
on the basis of 15 studies. his latter inding has an intuitive appeal,
in that CBT was originally developed for depressive symptoms, and
both CBT for anxiety and depression and the CBT for psychosis use
broadly similar principles. It is therefore important to examine this
efect of CBTp on depressive symptoms.
he aim of the current article is to investigate the number of
studies that include or address changes in depressive symptoms in
the course of CBT treatment for psychosis.

Searched source
On March, 10, 2015, we searched the Embase, Medline, Current
Contents, Web of Science, PsychInfo, and the Cochrane Collaborative
Register of Trials. Additionally we hand searched grey literature, and
cotacted leaders in the ield.
Search strategy
We performed our search using the following search terms either
as key terms or as key words:
(SCHIZO* or SCHIZOPHRENIA or SCHIZOAFFECTIVE
DISORDER) AND (COGNITIVE
THERAPY or COGNITIVE BEHAVIOUR THERAPY or
COGNITIVE BEHAVIOR THERAPY) AND (RANDOM or
RANDOMISED CONTROL TRIAL or CLINICAL TRIAL).
Background
Approximately one third of those diagnosed with schizophrenia
have concurrent depression, with these prevalence rates remaining
highly consistent over time, study population, phase of the illness,
and measures of depression. Comorbid depression has a considerable
impact on the diagnosis, progression, and treatment of schizophrenia
[1,2]. Depressive symptoms are associated with considerable long-
term hindrance on the treatment of schizophrenia; those with
depressive symptoms are more likely to use relapse-related mental
health services, have poor social and family relationships, pose a
greater danger to self and others, and have a lower quality of life,
motivation, mental and physical health, lower level of functioning,
and lower level of medication adherence [1,2].
Since the 1980s, Cognitive Behavioural herapy (CBT) has been
used as a method of treatment for afective disorders and has been
integrated into common practice [3]. CBT was initially developed
based on Beck’s priniciples of cognitive therapy for depression [4].
Although, Beck described use of CBT for psychosis [5], the irst
controlled studies on Cognitive Behaviour herapy For Psychosis
(CBTp) emerged in the early 1990s in the United Kingdom, and
this treatment has developed and included some of the theoretical
underpinnings of CBT from other disorders. he irst controlled
studies on Cognitive Behaviour herapy For Psychosis (CBTp)
emerged in the early 1990s in the United Kingdom, and this treatment

Reviews of studies of CBTp have suggested that they are useful
for the treatment of schizophrenia, and CBT for psychosis is now
recognised as an intervention for schizophrenia in clinical guidelines
