Abstract

Objective: Patients with schizophrenia perform generally worse on various nonverbal emotional measures than healthy participants. But inconsistency of emotion-specific difficulties has been observed among different ethnicities and
cultures. Using native stimuli may help minimize these potential confounding factors. Thus, the objective of this study was to apply a culturally suitable, dual modality nonverbal instrument with native stimuli to examine emotional recognition
deficits in Han Chinese patients with schizophrenia in Taiwan.

Method: We developed the Diagnostic Analysis of Non-verbal Aaccuracy-2-Taiwan to evaluate nonverbal emotion recognition accuracy. We compared emotion cognition and cognitive reservoir between 26 patients with schizophrenia and 39 healthy study participants.

Results: Patients with schizophrenia displayed less accuracy in negative emotion recognition, especially significantly less anger for both facial (p <0.01) and prosodic (p < 0.01) emotions, and significantly less fear expression (p < 0.05) for prosodic modality compared to healthy study participants.

Conclusion: Emotion-specific deficits might present across different cultures. Prosodic emotion recognition deficit, and specifically anger rather than fear or else recognition, may be a more culture-specific deficit for in schizophrenia in ethnic Han population. Culturally suitable stimuli might provide a more delicate measurement of emotion recognition deficits.
