长期以来，情感体验的缺失一直被视为精神分裂症的核心特征。许多研究表明，精神分裂症患者报告的快乐比控制时，报告非当前的感觉，使用特质，假设，前瞻性和回顾性的情绪自我报告格式，然而，目前的研究表明，精神分裂症患者和对照组没有不同的主观反应，情绪刺激在大多数实验室研究。虽然大量的注意力已经支付给精神分裂症的自我报告效价的研究，唤醒情感刺激反应的主观报告已被忽视。了解唤醒在精神分裂症中的作用是必要的，因为效价和唤醒与生理和行为反应有差异。为了了解自我报告唤醒的作用，对精神分裂症患者和健康对照者采用实验室情绪诱导范式的26项已发表研究进行了荟萃分析。Medline、PsycINFO、Web of Science和PubMed电子数据库和已识别文章的参考文献列表用作数据源。使用随机效应模型，分析表明，对照组和精神分裂症患者报告了相似的主观唤醒水平，以应对愉快和不愉快的刺激;然而，精神分裂症患者报告说，经历了更大的唤醒比对照组在中性刺激。此外，主持人的分析表明，性别和方法的因素，如评级规模和刺激类型，可能会影响这些模式的结果，并发挥关键作用，确定患者和对照组是否有不同的自我报告的觉醒。
Abnormalities in emotional experience have long been viewed as core features of schizophrenia. Numerous studies indicate that people with schizophrenia report less pleasure than controls when reporting non-current feelings using trait, hypothetical, prospective, and retrospective emotional self-report formats; however, current research has demonstrated that schizophrenia patients and controls do not differ in their subjective reactions to emotional stimuli in most laboratory studies. Although substantial attention has been paid to studies examining self-reported valence in schizophrenia, subjective reports of arousal in response to affective stimuli have been neglected. Understanding the role of arousal in schizophrenia is imperative given that valence and arousal are differentially associated with physiological and behavioral responses. To understand the role of self-reported arousal, a meta-analysis of 26 published studies employing laboratory emotion induction paradigms in patients with schizophrenia and healthy controls was conducted. Medline, PsycINFO, Web of Science, and PubMed electronic databases and reference lists from identified articles were used as data sources. Using a random effects model, analyses demonstrated that controls and people with schizophrenia reported similar levels of subjective arousal in response to pleasant and unpleasant stimuli; however, people with schizophrenia reported experiencing greater arousal than controls in response to neutral stimuli. Furthermore, moderator analyses suggested that gender and methodological factors, such as rating scale and stimulus type, may affect these patterns of results and play a key role in determining whether patients and controls differ in self-reported arousal.
