Pleasure Experience and Emotion Expression in Patients with Schizophrenia

Abstract

Background: Impairments in emotional experience and expression have been observed in patients with schizophrenia. However, most previous studies have been limited to either emotional experience (especially anhedonia) or expression. Few studies have examined both the experience and expression of emotion in schizophrenia patients at the same time. Aims: The present study aimed to examine pleasure experience and emotion expression in patients with schizophrenia. In particular, we specifically examined the relationship between emotion impairments (both pleasure experience and expression) and negative symptoms. Methods: One hundred and fifty patients completed the Temporal Experience of Pleasure Scale and Emotional Expressivity Scale. Results: Schizophrenia patients exhibited deficits in experiencing pleasure, but showed intact reported emotion expression. Patients with prominent negative symptoms showed reduced anticipatory pleasure, especially in abstract anticipatory pleasure. Conclusion: The present findings suggest that patients with schizophrenia have deficits in pleasure experience, while their abilities to express emotion appear intact. Such deficits are more severe in patients with prominent negative symptoms.
