Abstract

Network theory and analysis is an emerging approach in psychopathology research that has received increasing attention across fields of study. In contrast to medical models or latent variable approaches, network theory suggests that psychiatric syndromes result from systems of causal and reciprocal symptom relationships. Despite the promise of this approach to elucidate key mechanisms contributing to the development and maintenance of eating disorders (EDs), thus far, few applications of network analysis have been tested in ED samples. We first present an overview of network theory, review the existing findings in the ED literature, and discuss the limitations of this literature to date. In particular, the reliance on cross-sectional designs, use of single-item self-reports of symptoms, and instability of results have raised concern about the inferences that can be made from network analyses. We outline several areas to address in future ED network analytic research, which include the use of prospective designs and adoption of multimodal assessment methods. Doing so will provide a clearer understanding of whether network analysis can enhance our current understanding of ED psychopathology and inform clinical interventions.

网络分析:理解饮食失调精神病理的创新框架
网络理论和分析是一种新兴的精神病理学研究方法,在各个研究领域受到越来越多的关注。与医学模型或潜在变量方法相反,网络理论认为精神症状是由因果和相互症状关系系统引起的。尽管这种方法有望阐明促进饮食失调(EDs)发展和维持的关键机制,但到目前为止,很少有网络分析在ED样本中的应用。我们首先概述了网络理论,回顾了ED文献中的现有发现,并讨论了迄今为止这些文献的局限性。特别是,对横断面设计的依赖,使用单项症状自我报告,以及结果的不稳定性,引起了人们对网络分析可以得出的推论的关注。我们概述了未来ED网络分析研究中需要解决的几个领域,包括前瞻性设计的使用和多模式评估方法的采用。这样做将更清楚地了解网络分析是否可以提高我们目前对ED精神病理学的理解,并为临床干预提供信息。

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.
