Bulimia nervosa is an eating disorder characterised by marked impairment to one's physical health and social functioning, as well as high rates of chronicity and comorbidity. This literature review aims to summarise existing academic research related to the symptom profile of BN, the costs and burden imposed by the illness, barriers to the receipt of care, and the evidence base for available psychological treatments. As a consequence of well-documented difficulties in accessing evidence-based treatments for eating disorders, efforts have been made towards developing innovative, diverse channels to deliver treatment, with several of these attempting to harness the potential of digital platforms. In response to the increasing number of trials investigating the utility of online treatments, this paper provides a critical review of previous attempts to examine digital interventions in the treatment of eating disorders. The results of a focused literature review are presented, including a detailed synthesis of a knowledgeable selection of high-quality articles with the aim of providing an update on the current state of research in the field. The results of the review highlight the potential for online self-help treatments to produce moderately sized reductions in core behavioural and cognitive symptoms of eating disorders. However, concern is raised regarding the methodological limitations of previous research in the field, as well as the high rates of dropout and poor adherence reported across most studies. The review suggests directions for future research, including the need to replicate previous findings using rigorous study design and methodology, as well as further investigation regarding the utility of clinician support and interactive digital features as potential mechanisms for offsetting low rates of engagement with online treatments.
神经性贪食症是一种饮食失调症，其特征是明显损害身体健康和社会功能，以及高慢性和共病率。本文献综述旨在总结有关 BN 症状特征、疾病带来的成本和负担、获得护理的障碍以及现有心理治疗证据基础的现有学术研究。由于获得饮食失调症循证治疗的困难众所周知，人们努力开发创新的、多样化的治疗途径，其中一些途径试图利用数字平台的潜力。鉴于越来越多的试验研究在线治疗的效用，本文对以前尝试检查数字干预治疗饮食失调症的尝试进行了批判性回顾。提出了一项重点文献综述的结果，包括对高质量文章的精心选择进行详细综合，旨在提供该领域当前研究状况的最新信息。审查结果突出了在线自助治疗在减少饮食失调症的核心行为和认知症状方面可能产生适度效果。然而，人们对该领域以前研究中的方法学局限性以及大多数研究报告的高辍学率和低依从性表示关注。审查提出了未来研究的方向，包括需要使用严格的研究设计和方法复制以前的发现，以及进一步研究临床医生支持和互动数字功能的效用，作为抵消在线治疗低参与率的潜在机制。
