Neurophysiological Correlate of Emotion Regulation by Cognitive Reappraisal and Its Association With Psychotic Symptoms in Early Psychosis.

ABSTRACT:

Background

Emotion dysregulation is crucial to both poor social functioning and psychotic symptom formation in patients with schizophrenia. The efficient use of emotion regulation strategies, such as cognitive reappraisal, has been less frequently observed in the early phases of psychotic disorder. It is unknown whether neurophysiological responses related to emotion regulation by cognitive reappraisal are altered in early psychosis.

Methods

Fifty-four patients with first-episode psychosis (FEP), 34 subjects at clinical high risk (CHR) for psychosis, and 30 healthy controls (HCs) participated in event-related potential recordings during a validated emotion regulation paradigm to measure the effect of cognitive reappraisal on emotion regulation. Late positive potentials (LPPs
