Ecological momentary assessment (EMA) is gaining importance in psychiatry. This article assesses the characteristics of patients who used a new electronic EMA tool: the MEmind Wellness Tracker. Over one year, 13811 adult outpatients in our Psychiatry Department were asked to use MEmind. We collected information about socio-demographic data, psychiatric diagnoses, illness severity, stressful life events and suicidal thoughts/behavior. We compared active users (N = 2838) and non-active users (N = 10,973) of MEmind and performed a Random Forest analysis to assess which variables could predict its use. Univariate analyses revealed that MEmind-users were younger (42.2 ± 13.5 years versus 48.5 ± 16.3 years; χ = 18.85; P < 0.001) and more frequently diagnosed with anxiety related disorders (57.9% versus 46.7%; χ = 105.92; P = 0.000) than non-active users. They were more likely to report thoughts about death and suicide (up to 24% of active users expressed wish for death) and had experienced more stressful life events than non-active users (57% versus 48.5%; χ = 64.65; P < 0.001). In the Random Forest analysis, 31 variables showed mean decrease accuracy values higher than zero with a 95% confidence interval (CI), including sex, age, suicidal thoughts, life threatening events and several diagnoses. In the light of these results, strategies to improve EMA and e-Mental Health adherence are discussed.
生态瞬时评估（EMA）在精神病学领域正变得越来越重要。本文评估了使用一种新型电子EMA工具——MEmind健康追踪器的患者的特征。在一年多的时间里，我们精神科的13811名成年门诊患者被要求使用MEmind。我们收集了有关社会人口统计学数据、精神疾病诊断、疾病严重程度、应激性生活事件以及自杀想法/行为的信息。我们比较了MEmind的活跃用户（N = 2838）和非活跃用户（N = 10973），并进行了随机森林分析，以评估哪些变量可以预测其使用情况。单因素分析显示，与非活跃用户相比，MEmind用户更年轻（42.2±13.5岁对48.5±16.3岁；χ = 18.85；P < 0.001），被诊断患有焦虑相关障碍的频率更高（57.9%对46.7%；χ = 105.92；P = 0.000）。他们更有可能报告有关死亡和自杀的想法（多达24%的活跃用户表达了想死的愿望），并且比非活跃用户经历了更多的应激性生活事件（57%对48.5%；χ = 64.65；P < 0.001）。在随机森林分析中，31个变量显示平均降低准确度值高于零，且95%置信区间（CI）包含该值，这些变量包括性别、年龄、自杀想法、危及生命的事件以及几种诊断。鉴于这些结果，本文讨论了改善EMA和电子心理健康依从性的策略。
