Emotional abnormalities are prominent features of schizophrenia. While the capacity for emotions is essential to social adaptation, little is known about the role of emotional experience in the social dysfunction observed in schizophrenia.
This study examined the contribution of emotional experience, neurocognition, and social cognition to functional outcome in schizophrenia.
Self-reported emotional experience (anhedonia, affect intensity, and emotion frequency) was assessed in 33 stable schizophrenic/schizoaffective patients and 33 healthy controls. Symptoms, neurocognition, social cognition, and functional outcome were also assessed.
Patients and controls exhibited good internal reliability on all self-report scales, except for negative affect intensity. Patients reported equally intense but less frequent positive emotions, more intense and frequent negative emotions, and more anhedonia. Results of hierarchical regression analyses showed that emotional experience accounted for significant amounts of variance of social adjustment independent of neurocognition and social cognition.
These data show that emotional experience can be reliably assessed and is an important determinant of functional outcome in schizophrenia.
情绪异常是精神分裂症的突出特征。虽然情绪能力对于社会适应至关重要,但对于精神分裂症患者观察到的社会功能障碍中情绪体验的作用知之甚少。
本研究探讨了情绪体验、神经认知和社会认知对精神分裂症患者功能结局的贡献。
对 33 名稳定的精神分裂症/分裂情感障碍患者和 33 名健康对照者进行了自我报告的情绪体验(快感缺失、情绪强度和情绪频率)评估。还评估了症状、神经认知、社会认知和功能结局。
患者和对照组在所有自我报告量表上均表现出良好的内部一致性,除了负性情绪强度。患者报告说,积极情绪的强度相同但频率较低,消极情绪的强度和频率更高,快感缺失更严重。分层回归分析的结果表明,情绪体验在独立于神经认知和社会认知的情况下,对社会适应有显著的可变性解释。
这些数据表明,情绪体验可以可靠地评估,并且是精神分裂症患者功能结局的重要决定因素。
