Abstract

OBJECTIVE: Neurocognitive impairments observed in psychotic disorder may impact on emotion recognition and theory of mind, resulting in altered understanding of the social world. Early intervention efforts would be served by further elucidation of this mechanism.

METHOD: Patients with a psychotic disorder (n=30) and a reference control group (n=310) were asked to offer emotional appraisals of images of social situations (EASS task). The degree to which case-control differences in appraisals were mediated by neurocognitive alterations was analyzed.

RESULTS: The EASS task displayed convergent and discriminant validity. Compared to controls, patients displayed blunted emotional appraisal of social situations (B=0.52, 95% CI: 0.30, 0.74, P<0.001; adjusted for age, sex and number of years of education: B=0.44, 95% CI: 0.20, 0.68, P<0.001), a difference of 0.88 (adjusted: 0.75) standard deviation. After adjustment for neurocognitive variables, the case-control difference was reduced by nearly 75% and was non-significant (B=0.12, 95% CI: -0.14, 0.39, P=0.37).

CONCLUSIONS: Neurocognitive impairments observed in patients with psychotic disorder may underlie misrepresentation of the social world, mediated by altered emotion recognition. A task assessing the social impact of cognitive alterations in clinical practice may be useful in detecting key alterations very early in the course of psychotic illness.
