Abstract

Background

Mentalization-based treatment (MBT) is an evidence based treatment for patients diagnosed with borderline personality disorder (BPD). Although MBT is effective, on average, for individuals with BPD, there are large individual differences in treatment outcomes. Research on predictors of the treatment effect of MBT, such as intelligence, is needed to determine which treatment is most effective for which ‘category’ of BPD patients, providing more knowledge about optimal indications.

Objective

The study aimed to investigate whether intelligence is associated with MBT outcomes in patients with BPD and exploratively studying the difference between two variants of MBT.

Methods and Procedures

A pre-post intervention design was used to examine the effects of MBT on BPD severity. Personal and social recovery were measured as secondary outcome measures. The association between intelligence and the degree of recovery was examined.

Results

No significant correlation was found between intelligence level and treatment efficacy. In addition, a negative correlation between IQ and personal and social recovery was found, indicating that, as IQ increased, the level of recovery decreased. Secondary subanalyses showed the treatment effect of MBT was large and significant in reducing BPD symptoms (Cohen's d = 1.5) and that there was no significant difference between the 2-day MBT and 3-day MBT programmes in terms of a decrease in BPD severity. However, a significant medium positive correlational relationship was found between intelligence and a decrease in BPD severity level for the 3-day MBT, which was not found for the 2-day MBT programme. This indicates that in the 3-day MBT programme, the higher the IQ, the higher the decrease in BPD severity level.

Conclusions and Implications

This study is the first to examine the association between intelligence and the outcome of MBT in BPD patients. It shows that patients with a wide range of intelligence (72–124) can equally benefit from MBT and that effectiveness of MBT was not influenced negatively by lower intelligence. Secondary subanalyses showed that this was particularly evident when the intervention was delivered within the context of a 2-day MBT programme. Nevertheless, further randomized studies are required to ascertain the relationship between IQ and treatment effectiveness, as well as other predictors of MBT outcomes.

边缘型人格障碍患者的智力和基于心智化治疗的治疗效果。

背景：心智化治疗（MBT）是针对被诊断为边缘型人格障碍（BPD）患者的一种循证治疗方法。虽然基于心智的治疗对边缘型人格障碍患者平均有效，但治疗结果存在很大的个体差异。需要对预测MBT治疗效果的因素（如智力）进行研究，以确定哪种治疗方法对哪 "类 "BPD患者最有效，从而为最佳适应症提供更多知识：本研究旨在调查智力是否与 BPD 患者的 MBT 治疗效果相关，并探索性地研究 MBT 两种变体之间的差异：方法和程序：采用前后干预设计来研究 MBT 对 BPD 严重程度的影响。个人和社会康复作为次要结果测量。对智力与康复程度之间的关系进行了研究：结果：智力水平与治疗效果之间没有发现明显的相关性。此外，智商与个人和社会康复之间呈负相关，表明随着智商的提高，康复程度也会降低。二级子分析表明，MBT 在减少 BPD 症状方面的治疗效果显著（Cohen's d = 1.5），在降低 BPD 严重程度方面，2 天 MBT 和 3 天 MBT 方案没有显著差异。然而，在为期 3 天的 MBT 方案中，智力与 BPD 严重程度的下降之间存在着明显的中正向相关关系，而在为期 2 天的 MBT 方案中却没有发现这种关系。这表明，在为期 3 天的 MBT 方案中，智商越高，BPD 严重程度的下降幅度就越大：本研究首次探讨了BPD患者的智力与MBT结果之间的关系。研究表明，智力范围广泛（72-124）的患者同样可以从MBT中获益，而且智力较低不会对MBT的效果产生负面影响。二次子分析表明，在为期 2 天的 MBT 计划中进行干预时，这一点尤为明显。不过，还需要进一步开展随机研究，以确定智商与治疗效果之间的关系，以及其他预测甲基溴治疗效果的因素。

期刊介绍： Clinical Psychology & Psychotherapy aims to keep clinical psychologists and psychotherapists up to date with new developments in their fields. The Journal will provide an integrative impetus both between theory and practice and between different orientations within clinical psychology and psychotherapy. Clinical Psychology & Psychotherapy will be a forum in which practitioners can present their wealth of expertise and innovations in order to make these available to a wider audience. Equally, the Journal will contain reports from researchers who want to address a larger clinical audience with clinically relevant issues and clinically valid research.
