Abstract

Objective

The aim of this study was to explore the effectiveness of schema therapy (ST) in older adults with borderline personality disorder (BPD).

Methods

Multiple baseline case series design with five BPD patients, with a mean age of 66. After a baseline phase with random length, patients received weekly ST sessions for a year, followed by follow-up sessions during 6 months. Participants rated the credibility of negative core beliefs weekly; various secondary outcome measures were assessed every 6 months (severity of BPD, early maladaptive schemas, schema modes, personality functioning, maladaptive personality traits, psychological distress and quality of life), and BPD diagnosis was assessed before baseline and after follow-up. Data were analysed with mixed regression analyses and paired t-tests.

Results

Results revealed that ST led to a significant decrease in credibility of negative core beliefs, with high effect sizes. All participants remitted from their BPD diagnosis.

Conclusion

This is the first study exploring the effectiveness of ST for BPD in older adults, and it suggests that ST can be a powerful intervention for this group of patients.

个人模式疗法对患有边缘型人格障碍的老年人的疗效：多基线病例系列设计。

研究目的本研究旨在探讨图式疗法（ST）对患有边缘型人格障碍（BPD）的老年人的疗效：方法：采用多基线病例系列设计，研究对象为五名 BPD 患者，平均年龄为 66 岁。在随机长度的基线阶段后，患者每周接受一次 ST 治疗，为期一年，然后在 6 个月内接受随访。参与者每周对负面核心信念的可信度进行评分；每 6 个月对各种次要结果进行评估（BPD 严重程度、早期适应不良图式、图式模式、人格功能、适应不良人格特质、心理困扰和生活质量），并在基线前和随访后对 BPD 诊断进行评估。数据采用混合回归分析和配对 t 检验进行分析：结果表明，ST 能显著降低负面核心信念的可信度，并具有较高的效应大小。所有参与者的 BPD 诊断均有所缓解：这是第一项探索 ST 对老年人 BPD 有效性的研究，它表明 ST 对这部分患者来说是一种有效的干预措施。
