使用了生态瞬时评估（EMA; Stone & Shiffman，1994）。描述和量化边缘型人格障碍（BPD）的动态过程-情感不稳定性。60例门诊患者（34例BPD和情感不稳定; 26例目前患有抑郁症，但没有BPD或情感不稳定）进行了大约1个月的电子日记，并随机提示他们的情绪状态，每天6次。结果表明，BPD患者（a）没有报告显著不同的积极或消极情绪平均水平;（B）随着时间的推移，他们的积极和消极情绪评分显示出显著更大的变异性;（c）在连续评分上表现出显著更大的不稳定性（即，与抑郁症患者相比，在敌意、恐惧和悲伤方面有较大的变化）;（d）在敌意评分方面，更有可能在连续的情况下报告极端的变化（参与者之间的变化评分>= 90百分位数）。结果说明不同的分析方法来量化的可变性和不稳定性的影响密集的纵向数据的基础上。此外，结果表明，电子日记的承诺，从个人在其自然环境中收集数据的临床研究和评估的目的。
Ecological momentary assessment (EMA; Stone & Shiffman, 1994) was used. to characterize and quantify a dynamic process-affective instability in borderline personality disorder (BPD). Sixty outpatients (34 with BPD and affective instability; 26 with current depressive disorder but not with BPD or affective instability) carried electronic diaries for approximately 1 month and were randomly prompted to rate their mood state up to 6 times a day. Results indicated that BPD patients (a) did not report significantly different mean levels of positive or negative affect; (b) displayed significantly more variability over time in their positive and negative affect scores; (c) demonstrated significantly more instability on successive scores (i.e., large changes) for hostility, fear, and sadness than did patients with depressive disorders; and (d) were more likely to report extreme changes across successive occasions (>= 90th percentile of change scores across participants) for hostility scores. Results illustrate different analytic approaches to quantifying variability and instability of affect based on intensive longitudinal data. Further, results suggest the promise of electronic diaries for collecting data from individuals in their natural environment for purposes of clinical research and assessment.
