The relationship between childhood trauma, psychotic symptoms, and cognitive schemas in patients with schizophrenia, their siblings, and healthy controls: results from the EU-GEI study.

The relationship between CT and positive symptoms seems to be mediated by negative cognitive schemas about self in schizophrenia.
