Treating Depressive Symptoms in Psychosis: A Network Meta-Analysis on the Effects of Non-Verbal Therapies.

ABSTRACT:

Aims

The aim of this study was to examine whether non-verbal therapies are effective in treating depressive symptoms in psychotic disorders.

Material and methods

A systematic literature search was performed in PubMed, Psychinfo, Picarta, Embase and ISI Web of Science, up to January 2015. Randomized controlled trials (RCTs) comparing a non-verbal intervention to a control condition in patients with psychotic disorders, whilst measuring depressive symptoms as a primary or secondary outcome, were included. The quality of studies was assessed using the 'Clinical Trials Assessment Measure for psychological treatments' (CTAM) scale. Cohen's d was calculated as a measure of effect size. Using a Network Meta-analysis, both direct and indirect evidence was investigated.
