Researchers have recently hypothesized that negative emotion in positive situations may be one mechanism for understanding emotion dysfunction in schizophrenia. Using ecological momentary assessment, we examined the relationship between emotion experience and environmental context in the daily lives of participants with and without schizophrenia. Participants with (n=47) and without schizophrenia (n=41) were provided a cellular telephone and called four times a day for one week. During each call participants rated their emotion experiences, described their current activities, and rated enjoyment from those activities. In line with previous research, participants with schizophrenia reported higher negative emotion overall relative to participants without schizophrenia, but equivalent levels of positive emotion and activity enjoyment. In line with the environment-incongruent negative emotion hypothesis, participants with schizophrenia evidenced a weaker relationship between reported enjoyment of current activities and current negative emotion compared to participants without schizophrenia. In addition, lower neurocognition predicted this weak relationship between negative emotion and context in the schizophrenia group. These findings provide ecologically valid support for environment-incongruent negative emotion in schizophrenia, and suggest that people with schizophrenia with more impaired neurocognition may have more difficulties regulating negative emotion.
研究人员最近提出假设，认为积极情境中的负面情绪可能是理解精神分裂症情绪功能障碍的一种机制。我们采用生态瞬时评估法，研究了精神分裂症患者与非精神分裂症患者日常生活中情绪体验与环境背景之间的关系。为47名精神分裂症患者和41名非精神分裂症患者提供了手机，并在一周内每天给他们打4次电话。每次通话时，参与者对自己的情绪体验进行评分，描述当前的活动，并对这些活动的愉悦程度进行评分。与之前的研究一致，精神分裂症患者总体上比非精神分裂症患者报告的负面情绪更高，但积极情绪和活动愉悦程度相当。与环境不一致的负面情绪假设一致，与非精神分裂症患者相比，精神分裂症患者报告的当前活动愉悦程度与当前负面情绪之间的关系较弱。此外，较低的神经认知能力预示着精神分裂症组中负面情绪与情境之间的这种弱关系。这些发现为精神分裂症中环境不一致的负面情绪提供了生态学上有效的支持，并表明神经认知受损更严重的精神分裂症患者在调节负面情绪方面可能有更多困难。
