对效价刺激的情绪体验的研究一直表明，精神分裂症患者有体验情绪的能力。具体来说，精神分裂症患者对积极和消极情绪诱发刺激的经历与正常人相似。然而，尚不清楚精神分裂症患者在标准化实验室环境之外是否经历了类似水平的积极情绪和消极情绪，就像他们在日常生活中一样。评估精神分裂症患者情绪体验的一种可靠方法是体验抽样法（ESM）或生态瞬时评估（EMA）。使用PRISMA荟萃分析指南，我们回顾了所有研究的文献，这些研究包括精神分裂症患者和非精神分裂症患者，以及参与者日常生活中的积极或消极情绪评估。目前的研究是对12项情绪体验EMA研究的荟萃分析，其中包括619名精神分裂症患者和730名健康对照。结果表明，精神分裂症患者一贯报告更多的消极情绪和积极情绪比健康对照组参与者少。这些发现不同于基于实验室的研究，这可能是由于几个因素，包括环境差异，在日常生活中更明显地出现的障碍的影响，或其他问题，如抑郁症，已被证明与精神分裂症的负面情绪有关。重要的是，这些发现与基于情绪体验的测量方法一致，为它们在研究和临床环境中的使用提供了一些支持。(C)© 2016 Elsevier B.V.版权所有。
Research on emotion experience in response to valenced stimuli has consistently shown that people with schizophrenia have the capacity to experience emotion. Specifically, people with schizophrenia report similar experiences to both positive and negative emotion-eliciting stimuli as individuals without the disorder. However, it is less clear if people with schizophrenia experience similar levels of positive emotion and negative emotion outside of standardized laboratory contexts, as in their daily lives. One reliable method for assessing emotion experience in schizophrenia has been the Experience Sampling Method (ESM), or Ecological Momentary Assessment (EMA). Using the PRISMA guidelines for meta-analysis, we reviewed the literature for all studies that included people with and without schizophrenia, and that included a positive or negative emotion assessment during participants' daily lives. The current study is a meta-analysis of 12 EMA studies of emotion experience, which included a total of 619 people with schizophrenia and 730 healthy controls. Results indicate that people with schizophrenia consistently report more negative and less positive emotion than healthy control participants. These findings differ from laboratory-based studies, which may be due to several factors, including environmental differences, effects of the disorder that appear more clearly in daily life, or additional concerns, such as depression, which has been shown to be related to negative emotion in schizophrenia. Importantly, these findings are in line with questionnaire-based measures of emotion experience, lending some support for their use in research and clinical settings. (C) 2016 Elsevier B.V.
