Emotional impairments have been observed in schizophrenia (SCZ)，major depressive disorder (MDD) and bipolar disorder (BD). The extant literature suggests that patients with SCZ exhibit a general deficit in experiential pleasure (especially in anticipatory pleasure) and emotion expression and regulation. patients with MDD and BD also exhibit different severity of the same impairments. However, little is known about the similarity and difference of emotional impairments shown by patients with SCZ, MDD and BD. The purpose of this study was to adopt a traps-diagnostic approach to systematically examine experiential pleasure, emotion expression and regulation in these three clinical groups.
We administered a set of self-reported measures to examine experiential pleasure, emotion expression and emotion regulation in 100 patients with SCZ, 100 patients with MDD, 100 patients with BD, and 80 demographically matched healthy controls. Moreover, given that self-reported data might be confounded by memory functions, we also administered tests to examine logical memory and visual reproduction, and controlled these performances as covariates for comparison between groups.
The results from ANCOVAs after controlling for IQ and depressive symptoms showed that:
(1) In emotional experience, patients with SCZ, MDD, and BD reported significantly lower total score on the Temporal Experience of Pleasure Scale (TEPS) than healthy controls. Only patients with SCZ and MDD reported significantly lower consummatory pleasure subscale score than healthy controls, and only patients with SCZ reported significantly lower anticipatory pleasure subscale score than healthy controls.
(2) In emotion regulation, patients with SCZ and BD both reported significantly lower cognitive reappraisal subscale score and total score on the Emotional Regulation Questionnaire (ERQ,) than healthy controls. Patients with BD also reported significantly lower suppression subscale score on the ERC2 than patients with SCZ, MDD and healthy controls.
In emotion expression, only patients with MDD reported a significantly higher total score an the Toronto Alexithymia Scale (TAS) than healthy controls. Patients with MDD and BD also reported significantly more difficulty in identifying and describing feelings than patients with SCZ and healthy controls. Only patients with SCZ reported significantly less externally-oriented thinking than healthy controls. In summary, significant differences were found in experiential pleasure, emotion expression and regulation between patients with SCZ, MDD, BD and healthy controls. Patients with SCZ exhibited impairments in experiential pleasure, emotion regulation and reappraisal, but not in emotion expression. Patients with MDD exhibited impairments in experiential pleasure (particularly in consummatory pleasure), emotion expression, but were intact in emotion regulation. Patients with BD exhibited impairments in experiential pleasure (consummatory pleasure) emotion regulation and emotion expression. These findings bridge the Knowledge gap in understanding the similarities and differences in experiential pleasure, emotion expression and regulation observed in these three diagnostic groups. These findings also provide insights for clinicians to formulate appropriate intervention and treatment.
