Abstract

Objective: Affective dysregulation is a core feature of borderline personality disorder (BPD), and some patients report dissociative symptoms. The present study investigated temporal dynamic relations between affective states and current experiences of depersonalization and derealization in daily life to test key theoretical premises of trauma models of dissociation.

Method: Patients with BPD (n = 42) or depressive disorders (n = 40), and nonclinical controls (n = 39) were assessed every 15 min for 13 hr within a single day using smartphone-based diaries.

Results: As expected, dynamic structural equation modeling results show the highest levels of average daily affective arousal, negative affective valence, and dissociation in the BPD group. As hypothesized, arousal and subsequent dissociation were significantly linked only in the BPD group, implying that momentary arousal above a person's daily average is followed by higher dissociation in the next measurement (∼15 min later). In addition, some patients with BPD reported less negative affective valence following dissociation.

Conclusions: Our findings suggest that changes in affective states play an important role at the onset of dissociation in patients with BPD. Subsequent relief from distress may explain maintenance. We recommend that clinicians provide means to regulate affect when dealing with dissociation. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

情感唤醒在时间上先于边缘型人格障碍患者的解离：初步经验取样研究。

目的：情感失调是边缘型人格障碍（BPD）的一个核心特征，部分患者会出现分离症状。本研究调查了情感状态与当前日常生活中人格解体和去人格化体验之间的时间动态关系，以检验创伤解离模型的关键理论前提：方法：使用基于智能手机的日记，对BPD（42人）或抑郁障碍患者（40人）和非临床对照组（39人）在一天13小时内每15分钟进行一次评估：正如预期的那样，动态结构方程建模结果显示，BPD 组的日均情感唤醒水平、负情感价位和分离度最高。正如假设的那样，只有在 BPD 组中，唤醒和随后的解离有明显的联系，这意味着瞬间的唤醒超过了一个人的日平均水平，随后在下一次测量中（15 分钟以后），解离会更高。此外，一些BPD患者在解离后的负性情感价位较低：我们的研究结果表明，情感状态的变化在 BPD 患者开始解离时起着重要作用。随后的痛苦缓解可能是维持解离的原因。我们建议临床医生在处理解离时提供调节情感的方法。(PsycInfo Database Record (c) 2024 APA，保留所有权利）。

期刊介绍： Psychological Trauma: Theory, Research, Practice, and Policy publishes empirical research on the psychological effects of trauma. The journal is intended to be a forum for an interdisciplinary discussion on trauma, blending science, theory, practice, and policy. The journal publishes empirical research on a wide range of trauma-related topics, including: -Psychological treatments and effects -Promotion of education about effects of and treatment for trauma -Assessment and diagnosis of trauma -Pathophysiology of trauma reactions -Health services (delivery of services to trauma populations) -Epidemiological studies and risk factor studies -Neuroimaging studies -Trauma and cultural competence
