Borderline personality disorder (BPD) and depression are characterized by negative emotionality, yet BPD is also theorized to be linked with emotional variability. The present study extends past work to a larger time scale and notes the degree to which stress-related emotional responses are variable or persistent across stressors using novel analytic models. Participants (N = 164) were undergraduate students who completed daily assessments of negative emotional responses to interpersonal stressors for 2 weeks. BPD and depression were associated with greater negative emotional intensity and greater emotional variability in response to nonsocial stressors. Only BPD features were associated with greater emotional variability in response to social stressors. This study is limited by its reliance on self-report in a nonclinical sample and limited within-person assessments. Data point to distinct constellations of emotional dysfunction in BPD and depression. Pending replication, these data may inform targeting of emotional dysfunction in treatment.

日常生活中的情绪变化和惯性：与边缘人格和抑郁症状的联系。

边缘型人格障碍 (BPD) 和抑郁症的特征是负面情绪，但理论上 BPD 也与情绪变化有关。本研究将过去的工作扩展到更大的时间尺度，并使用新颖的分析模型记录了与压力相关的情绪反应在压力源中可变或持续的程度。参与者 (N = 164) 是本科生，他们在 2 周内完成了对人际压力源的负面情绪反应的日常评估。BPD 和抑郁症与更大的负面情绪强度和更大的情绪变化有关，以应对非社会压力源。只有 BPD 特征与对社会压力源的更大情绪变化有关。这项研究因依赖非临床样本中的自我报告和有限的个人评估而受到限制。数据指出 BPD 和抑郁症中情绪功能障碍的不同星座。在复制之前，这些数据可能会告知治疗中情绪功能障碍的目标。
