Background: Borderline personality disorder is a debilitating and prevalent mental health disorder, with often inaccessible treatment options. Electronically delivered dialectical behavioral therapy could be an efficacious and more accessible intervention. Objective: We aimed to evaluate the efficacy of electronic delivery of dialectical behavioral therapy in the treatment of individuals with symptoms of borderline personality disorder. Methods: Study participants diagnosed with borderline personality disorder were offered either an email-based or in-person group format dialectical behavioral therapy skill-building program. During each session, participants were provided with both the material and feedback regarding their previous week’s homework. Electronically delivered dialectical behavioral therapy protocol and content were designed to mirror in-person content. Participants were assessed using the Self-Assessment Questionnaire (SAQ) and Difficulties in Emotion Regulation Scale (DERS). Results: There were significant increases in SAQ scores from pre- to posttreatment in the electronic delivery group (F_1,92=69.32, P<.001) and in-person group (F_1,92=60.97, P<.001). There were no significant differences observed between the groups at pre- and posttreatment for SAQ scores (F_1,92=.05, P=.83). There were significant decreases in DERS scores observed between pre- and posttreatment in the electronic delivery group (F_1,91=30.15, P<.001) and the in-person group (F_1,91=58.18, P<.001). There were no significant differences observed between the groups for DERS scores pre- and posttreatment (F_1,91=.24, P=.63). There was no significant difference in treatment efficacy observed between the 2 treatment arms (P<.001). Conclusions: Despite the proven efficacy of in-person dialectical behavioral therapy in the treatment of borderline personality disorder, there are barriers to receiving this treatment. With the prevalence of internet access continuing to rise globally, delivering dialectical behavioral therapy with email may provide a more accessible alternative to treatment for individuals with borderline personality disorder without sacrificing the quality of care.

通过电子邮件在边缘性人格障碍患者中提供辩证行为治疗技术的有效性：非随机对照试验

背景：边缘型人格障碍是一种令人衰弱的普遍性心理健康障碍，通常无法获得治疗选择。以电子方式进行的辩证行为疗法可能是一种有效且更容易获得的干预措施。目的：我们旨在评估辩证行为疗法的电子递送对边缘性人格障碍症状患者的疗效。方法：为被诊断为边缘性人格障碍的研究参与者提供基于电子邮件或面对面小组形式的辩证行为疗法技能培养计划。在每节课中，都向参与者提供了有关他们前一周家庭作业的材料和反馈。电子提供的辩证行为疗法协议和内容旨在反映个人内容。使用自我评估问卷（SAQ）和情绪调节困难量表（DERS）对参与者进行评估。结果：在电子治疗组（F _1,92 = 69.32，P <.001）和当面治疗组（F _1,92），从治疗前到治疗后的SAQ得分均显着增加。= 60.97，P <.001）。治疗前和治疗后SAQ评分在两组之间没有显着差异（F _1,92 = .05，P = .83）。电子治疗组（F _1,91 = 30.15，P <.001）和面对面治疗组（F _1,91 = 58.18，P <.001）之间在治疗前和治疗后观察到的DERS得分显着降低。。治疗前后DERS评分在两组之间没有显着差异（F _1,91 = .24，P = .63）。在两个治疗组之间，观察到的治疗效果没有显着差异（P <.001）。结论：尽管亲自辩证行为疗法在治疗边缘型人格障碍方面已证明有效，但仍存在接受该疗法的障碍。随着全球互联网访问率的持续上升，在不牺牲护理质量的情况下，通过电子邮件提供辩证行为疗法可能为边缘性人格障碍患者提供更容易获得的替代治疗方法。试用注册： ClinicalTrials.gov NCT04493580；https://clinicaltrials.gov/ct2/show/NCT04493580
