Abstract
AIMS:
Recent research has shown emotion recognition to be impaired in individuals at ultra-high risk (UHR) for developing a psychotic disorder compared to healthy controls. This longitudinal study aimed to examine whether disturbed emotion recognition measured in UHR participants at baseline predicts transition to a psychotic disorder within 12months.
METHODS:
Thirty-seven UHR participants aged 13-22years participated in the study. At baseline participants completed face and prosody emotion recognition tasks, as well as measures of psychopathology, functioning, and IQ. Transition to a psychotic disorder over 12months was the primary outcome. A series of Cox regressions was performed with emotion recognition as the predictor variable, while controlling for covariates, with time to transition to a psychotic disorder as the dependent variable.
RESULTS:
Eleven (29.7%) of the 37 participants transitioned to a psychotic disorder over the 12-month follow-up period. Total face or prosody emotion recognition accuracy was not predictive of transition to a psychotic disorder. However, examination of recognition of specific emotions, while controlling for positive, negative and global symptoms and functioning, revealed that accuracy in identifying neutral (p=.037) and fearful (p=.015) emotion predicted transition to a psychotic disorder. Specifically, lower accuracy in identifying neutral emotion and higher accuracy in identifying fearful emotion were predictive of transition to a psychotic disorder within 12months. Examination of the separate modalities revealed that this finding held for face but not for prosody emotion recognition.
CONCLUSION:
These findings suggest that emotion recognition abilities may be prognostic for the development of psychotic disorders, but further studies are needed.
