Borderline personality disorder (BPD) and persistent depressive disorder (PDD) are related to interpersonal dysfunction which might become particularly apparent in situations of social exclusion (SE). While emotional responses to SE have been widely explored, behavioral data in clinical samples are lacking. In this cross-diagnostic study, we applied a variant of the Cyberball paradigm to investigate the dynamic behavioral response to partial SE in BPD and PDD. BPD patients (n = 36), PDD patients (n = 34) and age and gender matched healthy controls (HC) (total n = 70) played experimental (i.e. partial SE Cyberball) and control (i.e. inclusion only) conditions in randomized order. While all groups tended to increase ball tosses towards the excluder in response to SE, this behavioral turn was significantly lower in PDD (p = .03, d = -.30) and trendwise in BPD patients (p = .06, d = -.28). Thus, an altered immediate response to partial SE was observed in BPD and PDD, in addition to the emotional reactions. This study supports the hypothesis of a behavioral coping with SE in BPD and PDD that might be problematic in the long run and provides an experimental paradigm for future research on interpersonal dysfunction.
边缘型人格障碍（BPD）和持续性抑郁障碍（PDD）与人际功能障碍有关，而人际功能障碍在社会排斥（SE）的情况下可能会变得尤为明显。虽然人们已经广泛研究了对 SE 的情绪反应，但在临床样本中缺乏行为数据。在这项跨诊断研究中，我们应用了一种变体的 Cyberball 范式来研究 BPD 和 PDD 患者对部分 SE 的动态行为反应。将 BPD 患者（n=36）、PDD 患者（n=34）和年龄、性别匹配的健康对照组（HC）（总 n=70）随机分为实验组（即部分 SE Cyberball）和对照组（即仅包含）。虽然所有组在 SE 下都倾向于增加对排斥者的投球次数，但 PDD 组的这种行为转变明显较低（p=0.03，d=-0.30），BPD 患者的趋势也较低（p=0.06，d=-0.28）。因此，除了情绪反应外，还观察到 BPD 和 PDD 对部分 SE 的即时反应发生了改变。这项研究支持了在 BPD 和 PDD 中存在对 SE 的行为应对的假设，这在长期内可能会有问题，并为未来研究人际功能障碍提供了一个实验范式。
