背景：计算机化的生态瞬时评估（EMAc）技术允许日常生活行为和经验的评估。本研究旨在探讨此评估方法在门诊精神分裂症患者中的可行性和有效性。研究方法：门诊精神分裂症或情感性精神障碍患者（n = 54）接受了一系列标准的实验室临床和功能结局指标，然后在个人数字助理（PDA）微型计算机上完成电子问卷，每天4次，持续1周。结果：一般情况下，良好的依从性（87%）与EMAc被发现，参与者积极评价他们的经验与研究。在日常生活中收集的数据显示了整个评估周的预期模式，并与测量类似结构的标准实验室仪器的评分显著相关。结论：EMAc是一个可行的和有效的方法来收集社区居住的精神分裂症患者的数据，它可以提供重要的信息，是无法通过标准的临床和功能结果的措施，在实验室管理。
Background: Computerized Ecological Momentary Assessment (EMAc) techniques permit the assessment of daily life behaviors and experiences. The present investigation examined the feasibility and validity of this assessment methodology in outpatients with schizophrenia. Methods: Outpatients with schizophrenia or schizoaffective disorder (n = 54) received a battery of standard laboratory clinical and functional outcome measures and then completed electronic questionnaires on a personal digital assistant (PDA) microcomputer 4 times per day for 1 week. Results: Generally good compliance (87%) with EMAc was found, and participants rated their experience with the study positively. The data collected in daily life demonstrated expected patterns across the assessment week and were significantly associated with scores from standard laboratory instruments measuring similar constructs. Conclusions: EMAc is a feasible and valid approach to data collection in community-dwelling people with schizophrenia, and it may provide important information that is inaccessible via standard clinical and functional outcome measures administered in the laboratory.
