经验抽样方法（ESM）涉及在日常生活中填写问卷，并已广泛用于精神分裂症患者，以评估症状和行为。尽管与访谈方法相比有相当大的优势，但关于其外部有效性的信息有限。我们的目的是调查精神分裂症患者和健康个体的ESM方案实施是否受到情绪、药物和症状等因素的不同影响，这些因素可能对有效性有影响。来自普通人群的53名精神分裂症患者和58名对照者连续6天每天完成7份ESM问卷。记录依从性和可接受性，包括总体经验、培训和正常程序的中断。精神分裂症患者的总体问卷完成率与对照组相当（即超过70%）。精神分裂症患者在早上完成的问卷数量明显减少，但在体验抽样期间没有表现出疲劳的影响。排除上午的问卷调查并没有显著改变调查结果。在精神分裂症组中，药物水平和症状对依从性没有影响。然而，在这一组中，更高的干扰与更少的问卷完成度相关。这些发现表明，尽量减少干扰可能会提高有效性和完成率。ESM是一种有效的方法，适用于精神分裂症患者。2016爱思唯尔爱尔兰有限公司版权所有。
Experience sampling methodology (ESM) involves completing questionnaires during daily life and has been used extensively in people with schizophrenia to assess symptoms and behaviours. Despite considerable advantages over interview measures, there is limited information about its external validity. Our aim is to investigate whether ESM protocol implementation is affected differentially in people with schizophrenia and healthy individuals by factors such as mood, medication and symptoms which would have implications for validity. Fifty-three people with schizophrenia and fifty-eight controls from the general population completed seven ESM questionnaires per day for six consecutive days. Compliance and acceptability, including overall experience, training and disruption of normal routines, were recorded. Overall questionnaire completion rate in people with schizophrenia was comparable to controls (i.e. over 70%). People with schizophrenia completed significantly fewer questionnaires in the morning but did not show fatigue effects over the experience sampling period. Excluding questionnaires in the morning did not significantly alter the findings. In the schizophrenia group medication level and symptoms did not influence adherence. However, higher disruption was associated with reduced questionnaire completion in this group. These findings suggest that minimising disruption may enhance validity and completion rates. ESM is a valid methodology, to use with people with schizophrenia. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
