Social cognition in patients with first episode of psychosis in remission.

AIM

The present study aimed to compare the social cognition (SC) deficits in patients with first-episode psychosis (FEP) and healthy controls and evaluate the association of SC deficits with socio-occupational functioning, insight, quality of life, and stigma.

METHODS

This study included 30 patients with FEP in remission phase and 26 healthy controls matched for age, gender, education, and intelligent quotient. SC was assessed on the domains of theory of mind (ToM), social perception, and attributional bias.

RESULTS

Compared to healthy controls, patients with FEP had significantly higher deficits in the domains of second-order ToM (unpaired = 4.447, < 0.001) and Faux Pas Composite Index (unpaired = 2.824, = 0.007). In the correlation analysis, higher age of patients with FEP was significantly associated with more externalizing bias (Pearson's correlation coefficient = 0.38, = 0.039) and those with lower level of education had more social cognitive deficits in the domains of Faux Pas Composite Index (Pearson's correlation coefficient = 0.43, = 0.018), Social Perception Index (Pearson's correlation coefficient = 0.38, = 0.04), and Nonsocial Perception Index (Pearson's correlation coefficient = 0.5, = 0.005). Duration of untreated psychosis was associated with higher deficits in the first-order ToM (Pearson's correlation coefficient = -0.38, = 0.04) and Externalizing Bias Index (Pearson's correlation coefficient = -0.49, = 0.006). Longer duration of treatment was associated with higher impairment in first-order ToM index (Pearson's correlation coefficient = -0.42, = 0.02). General psychopathology and total Positive and Negative Syndrome Scale total score correlated significantly with externalizing bias, with a higher level of psychopathology associated with more severe deficits in this domain. There was no correlation of SC with the quality of life, cognitive insight, and stigma (except for occasional correlation of stereotype endorsement and externalizing bias).

CONCLUSION

The present study suggests that compared to healthy controls, patients with FEP have impairment in the domains of second-order ToM and Faux Pas Composite Index. However, social cognitive deficits have only a few correlations with various psychosocial outcomes of FEP.
