Psychosis: Psychotherapy vs. Control

General Description

The data-psychosis-psyctr dataset is a meta-analytic research domain MARD which is part of the Metapsy project. The dataset contains study information and effect size data of randomized trials on psychological interventions for schizophrenia and psychosis. The date of the last search update is provided here. More details about a larger version of this dataset can be accessed in the published network meta-analysis.

This dataset includes psychological interventions vs. control (psy vs ctr) comparisons. Effect sizes are provided for three types of outcomes at post-test: total symptoms, negative symptoms, and positive symptoms. It includes one type of effect size calculation per study, giving priority to change scores, followed by means and standard deviations at post-test.

The dataset follows the Metapsy data standard.
