Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This clinical trial tests the effectiveness of cognitive therapy (CT) to improve outcomes in outpatients diagnosed with schizophrenia or schizoaffective disorder who manifest prominent negative symptoms. It is hypothesized that patients receiving cognitive therapy will manifest lower negative symptom levels and improved engagement in constructive activity relative to patients who receive treatment-as-usual. Further, it is predicted that these differences between CT and TAU will be larger when patients are assessed 6 and 12 months after the end of treatment (18 and 24 months after study entry).
