Abstract

Objective

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.

Methods

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.

Results

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.

Discussion

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.

复原力 eDBT：针对进食障碍的辩证行为疗法技能培训应用程序的开发和可用性评估。

目的：辩证行为疗法（DBT）是一种针对以反复暴饮暴食为特征的疾病的循证治疗方法。然而，获得像 DBT 这样的专业治疗的机会仍然有限。为了提高 DBT 的可及性，我们开发了一款 DBT 技能培训应用程序（Resilience：eDBT），用于控制饮食失调（ED）症状。本文描述了 Resilience 的开发过程，并测试了其可用性：方法：本文提供了有关 Resilience 开发和特点的描述性信息，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。通过混合方法对 10 名有症状的人进行了可用性评估。定性数据以现有框架为基础进行整理，其中包括六个主题：可用性、视觉设计、用户参与、内容、治疗说服力和治疗联盟：Resilience 的系统可用性量表得分高达 85.5 分，超过了建议的 68 分。根据访谈数据，该应用程序的积极方面是易用性和可视化设计，而增加同伴支持被认为是一个改进的机会：讨论：基于 DBT 的新型应用程序可作为一种可接受的低强度选择或传统治疗的辅助手段，用于治疗日常生活中出现的 ED 症状。然而，其显著的局限性包括样本量较小，以及进行可用性评估的时间点单一。

期刊介绍： Articles featured in the journal describe state-of-the-art scientific research on theory, methodology, etiology, clinical practice, and policy related to eating disorders, as well as contributions that facilitate scholarly critique and discussion of science and practice in the field. Theoretical and empirical work on obesity or healthy eating falls within the journal’s scope inasmuch as it facilitates the advancement of efforts to describe and understand, prevent, or treat eating disorders. IJED welcomes submissions from all regions of the world and representing all levels of inquiry (including basic science, clinical trials, implementation research, and dissemination studies), and across a full range of scientific methods, disciplines, and approaches.
