边缘型人格障碍(borderline personality disorder，BPD)以情绪调节、人际关系、自我形象和冲动控制不稳定为主要特征，是一种发病率高、死亡率高、治疗难度大的精神障碍。该疾病治疗主要以心理治疗为主，但目前主流的心理治疗如辩证行为疗法(dialectical behavior therapy，DBT)都存在一定局限性，因此有必要寻找一种更加方便有效的治疗方法。接纳承诺疗法(acceptance and commitment therapy，ACT)作为第三代认知疗法中的代表疗法，旨在使个体接纳无法避免的痛苦，发现自身价值所在并承诺行动，最终提高心理灵活性过上富有意义的生活。接纳承诺疗法目前已被应用在多种精神障碍的治疗中，且疗效显著。文章通过阐述边缘型人格障碍的发病机制及接纳承诺疗法的理论模型，分别从接纳承诺疗法的病理模型和治疗模型分析了接纳承诺疗法干预边缘型人格障碍的合理性和可行性。最后综述了近年来接纳承诺疗法治疗边缘型人格障碍的研究结果，结果表明接纳承诺疗法为边缘型人格患者的治疗提供了一种有希望的方法，但还需要更多的研究来证明它在边缘型人格障碍群体中的使用及其具体的作用机制。“,”Borderline personality disorder (BPD) is characterized by emotional regulation, interpersonal relationship, self-image and impulse control instability. It is a mental disorder with high morbidity, high mortality and difficult treatment. Psychotherapy is the main treatment for this disease. However, current mainstream psychotherapy, such as dialectical behavior therapy (DBT), has certain limitations, so it is necessary to find a more convenient and effective treatment method. Acceptance and commitment therapy (ACT), as the representative therapy of the third generation of cognitive therapy, aims to make individuals accept inevitable pain, find their own value and commit to action, and finally improve their psychological flexibility to live a meaningful life. ACT has been used in the treatment of a variety of mental disorders, and the effect is significant. By expounding the pathogenesis of BPD and the theoretical model of ACT, this paper analyzed the rationality and feasibility of ACT intervention in BPD from the pathological model and treatment model of ACT. Finally, the research results of ACT treating BPD in recent years were summarized. The results show that ACT provides a promising method for the treatment of BPD patients, however, more studies are needed to prove its use in this group and its specific mechanism.
