Dialectical behavior therapy (DBT) is an evidence-based treatment for disorders characterized by recurrent binge eating. Yet, access to specialized treatment like DBT remains limited. To increase the accessibility of DBT, we developed a DBT skills training app (Resilience: eDBT) for the management of eating disorder (ED) symptoms. This paper delineates the developmental process of Resilience and tests its usability.
Descriptive information on the development and features of Resilience is provided, including its framework, content structure and delivery formats, functionality, data storage procedure, and privacy protocols. Usability was assessed via a mixed methods approach in 10 symptomatic individuals. Qualitative data were organized based on an existing framework, which included six themes: usability, visual design, user engagement, content, therapeutic persuasiveness, and therapeutic alliance.
Resilience demonstrated good usability via a Systems Usability Scale score of 85.5, which exceeded the recommended cutoff of 68. Positive aspects of the app, according to interview data, were the ease of use and the visual design, while the addition of peer support was suggested as an opportunity for improvement.
A novel DBT-based app may serve as an acceptable, low-intensity option or adjunct to traditional treatment for targeting ED symptoms that emerge in daily life. However, notable limitations include the small sample size and the single time point at which the usability assessment was conducted.
辩证行为疗法（DBT）是一种针对以反复暴食为特征的疾病的循证治疗方法。然而，获得像 DBT 这样的专业治疗仍然有限。为了增加 DBT 的可及性，我们开发了一款名为 Resilience 的 DBT 技能训练应用程序（Resilience：eDBT），用于治疗饮食障碍（ED）症状。本文阐述了 Resilience 的开发过程，并对其可用性进行了测试。
提供了关于 Resilience 的开发和功能的描述性信息，包括其框架、内容结构和交付格式、功能、数据存储程序和隐私协议。通过对 10 名有症状的个体进行混合方法评估，评估了可用性。定性数据根据现有的框架进行了组织，该框架包括六个主题：可用性、视觉设计、用户参与度、内容、治疗说服力和治疗联盟。
Resilience 的系统可用性量表得分为 85.5，超过了 68 的建议临界值，表明其具有良好的可用性。根据访谈数据，该应用程序的优点是易于使用和视觉设计，而添加同伴支持被认为是一个改进的机会。
一种新的基于 DBT 的应用程序可以作为针对日常生活中出现的 ED 症状的传统治疗的可接受、低强度的选择或辅助手段。然而，值得注意的是，样本量小和仅在一个时间点进行可用性评估是其明显的局限性。
