Dialectical behavior therapy (DBT) has been found to be an efficacious treatment for disorders characterized by high levels of emotional instability. In view of the multifaceted applications of DBT and the extent to which mental disorders can incapacitate cognitive functions, the current systematic review aimed to investigate the effect of DBT in strengthening cognitive functions across various mental health conditions. Original research studies employing both experimental and quasi-experimental designs were included in the review. The literature search was done using different electronic databases, from the first available literature until June 2022, that covered an approximate period of ten years. Joanna Briggs Institute checklist was used to assess the methodological rigor of the studies. Twelve studies conducted on adolescents with emotional dysregulation, and adults with borderline personality disorder, bipolar disorder, attention deficit hyperactivity disorder, and multiple sclerosis were selected. Results indicate that DBT has the potential to improve key cognitive functions such as attention, memory, fluency, response inhibition, planning, set shifting, tolerance for delayed rewards and time perception, as assessed by neuropsychological tests, self-report of cognitive functions, and neuroimaging techniques. Considering the review's findings that showcase the effectiveness of DBT in fostering improvements in cognitive functions, DBT may possibly be chosen as a preferred treatment to ensure that patients reach optimal levels of cognitive functioning. Limitations include lack of sufficient studies encompassing all the common mental health conditions, usage of neuroimaging techniques as only an indirect measure of cognitive functioning and nuances related to the quality of individual studies.
辩证行为疗法（DBT）已被发现是治疗以情绪高度不稳定为特征的疾病的一种有效疗法。鉴于DBT的多方面应用以及精神障碍对认知功能的致残程度，当前的系统评价旨在研究DBT在各种心理健康状况下增强认知功能的效果。纳入评价的原始研究采用了实验性和准实验性设计。文献检索使用了不同的电子数据库，涵盖从最早可得文献到2022年6月这大约十年的时间。采用乔安娜·布里格斯研究所清单来评估研究的方法学严谨性。选取了12项针对情绪调节障碍青少年以及患有边缘性人格障碍、双相情感障碍、注意力缺陷多动障碍和多发性硬化症的成年人开展的研究。结果表明，通过神经心理学测试、认知功能的自我报告以及神经影像学技术评估，DBT有潜力改善关键认知功能，如注意力、记忆力、流畅性、反应抑制、计划、任务切换、对延迟奖励的耐受性和时间感知。考虑到该评价结果显示DBT在促进认知功能改善方面的有效性，DBT可能会被选为首选治疗方法，以确保患者达到最佳认知功能水平。局限性包括缺乏涵盖所有常见心理健康状况的足够研究、将神经影像学技术仅用作认知功能的间接测量方法以及与个别研究质量相关的细微差别。
