Abstract

Purpose: Evidence shows that dialectical behavioural therapy (DBT) is efficacious for eating disorders (ED), yet few people have access to specialized treatments like DBT. Translating key DBT skills for delivery via a smartphone application may broaden the dissemination of evidence-based interventions. However, prior to developing a DBT-based app, it is crucial to gather information on target-user needs and preferences. Assessing overall acceptance and identifying predictors of acceptance, informed by the UTAUT framework, is also important. This process ensures not only a demand for such an app, but also that users receive content and features tailored to their needs.

Method: This study aimed to understand target-user preferences of DBT-based apps for EDs by assessing willingness to engage, overall acceptance levels, and preferred functionality/content delivery modes (n = 326 symptomatic participants).

Results: Eighty-eight percent indicated they would be willing to use a DBT-based ED app if it were available. Acceptance levels of a DBT app were high (64%), which was uniquely predicted by performance expectancy (perceptions of how beneficial an intervention is) and facilitating conditions (expectations of technological infrastructure and support in interventions) in path analysis. Content perceived as important to contain were emotion regulation techniques, tailored intervention strategies, and psychoeducation.

Conclusion: Findings generate important information about target-user preferences of a DBT-based app for EDs, highlighting necessary design principles for apps of this kind. Level of evidence Level V, cross-sectional descriptive study.

针对饮食失调的辩证行为疗法智能手机应用程序的目标用户偏好、动机和接受度。
目的:有证据表明,辩证行为疗法(DBT)对进食障碍(ED)有疗效,但很少有人能获得像 DBT 这样的专业治疗。将关键的 DBT 技能转化为智能手机应用程序,可以扩大循证干预的传播范围。然而,在开发基于 DBT 的应用程序之前,收集有关目标用户需求和偏好的信息至关重要。根据UTAUT框架评估总体接受度并确定接受度的预测因素也很重要。这一过程不仅能确保对此类应用程序的需求,还能确保用户获得符合其需求的内容和功能:本研究旨在通过评估参与意愿、总体接受程度以及首选功能/内容交付模式(n = 326 名有症状的参与者),了解目标用户对基于 DBT 的 ED 应用程序的偏好:结果:88%的人表示,如果有基于 DBT 的 ED 应用程序,他们愿意使用。对 DBT 应用程序的接受程度很高(64%),在路径分析中,性能预期(对干预有多大益处的认知)和便利条件(对干预中的技术基础设施和支持的预期)对其进行了独特的预测。被认为重要的内容包括情绪调节技巧、量身定制的干预策略和心理教育:结论:研究结果提供了有关目标用户对基于 DBT 的 ED 应用程序偏好的重要信息,强调了此类应用程序的必要设计原则。证据等级 V 级,横断面描述性研究。

期刊介绍: Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity is a scientific journal whose main purpose is to create an international forum devoted to the several sectors of eating disorders and obesity and the significant relations between them. The journal publishes basic research, clinical and theoretical articles on eating disorders and weight-related problems: anorexia nervosa, bulimia nervosa, subthreshold eating disorders, obesity, atypical patterns of eating behaviour and body weight regulation in clinical and non-clinical populations.
