BPD Compass is a transdiagnostic psychotherapy that includes cognitive, behavioral, and mindfulness skills targeting the personality dimensions of negative affectivity, disinhibition, and antagonism. Given considerable symptom comorbidity and overlap in etiology between borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD), this study investigated whether BPD Compass holds promise as an integrated approach to simultaneously treating co‐occurring BPD features and PTSD symptoms. Participants included 84 trauma‐exposed adults who participated in a two‐phase clinical trial (Phase 1: randomized controlled trial of BPD Compass vs. waitlist [n = 43]; Phase 2: open trial of BPD Compass [n = 41]). Compared to waitlist, BPD Compass led to medium‐to‐large–sized, significant improvements in BPD features, βs = −.57 −.44, and facets of neuroticism, βs < −.55–−.73, as well as small, nonsignificant improvements in self‐reported, β = −.20, and clinician‐rated PTSD symptom severity, β = −.19. During treatment, within‐person improvements in PTSD symptoms predicted subsequent improvements in BPD features, β = .13, but not vice versa, β = .07. Within‐person PTSD symptom reduction also predicted subsequent improvement in all personality dimensions, whereas only within‐person improvement in despondence, β = .12, affective dysregulation, β = .11, and dissociative tendencies, β = .12, predicted PTSD symptom reductions. Findings offer preliminary support for the potential of BPD Compass to target BPD features and aspects of neuroticism and agreeableness among trauma‐exposed adults. Moreover, PTSD symptom change predicting subsequent improvement in BPD features runs counter to current stage‐based treatment models that emphasize BPD feature stabilization before engaging in trauma‐focused therapy.

BPD Compass：使用精神病理学的维度模型来治疗同时发生的边缘性人格障碍和创伤后应激症状

BPD Compass 是一种跨诊断心理疗法，包括针对消极情感、去抑制和对抗等人格维度的认知、行为和正念技能。鉴于边缘性人格障碍 (BPD) 和创伤后应激障碍 (PTSD) 之间存在相当多的症状共病和病因学重叠，本研究调查了 BPD Compass 是否有望成为同时治疗同时出现的 BPD 特征和 PTSD 症状的综合方法。参与者包括 84 名经历过创伤的成年人，他们参加了两阶段临床试验（第一阶段：BPD Compass 与候补名单的随机对照试验[n= 43]；第 2 阶段：BPD Compass 公开试用 [n =41]）。与候补名单相比，BPD Compass 带来了中型到大型的 BPD 特征显着改善，βs = −.57 −.44，以及神经质方面，βs < −.55–−.73，以及小，自我报告的无显着改善，β = -.20，以及临床医生评定的 PTSD 症状严重程度，β = -.19。在治疗期间，PTSD 症状的个人改善预示着 BPD 特征的后续改善，β = 0.13，但反之则不然，β = 0.07。人体内 PTSD 症状的减轻也预示着所有人格维度的后续改善，而只有人体内的抑郁改善（β = .12）、情感失调（β = .11）和解离倾向（β = .12）预测 PTSD 症状减轻。研究结果为 BPD Compass 针对遭受创伤的成年人的 BPD 特征以及神经质和宜人性方面的潜力提供了初步支持。此外，预测 BPD 特征随后改善的 PTSD 症状变化与当前基于阶段的治疗模型背道而驰，该治疗模型在进行创伤聚焦治疗之前强调 BPD 特征稳定。
