Emerging evidence suggests that loss of control (LOC) may present as a common feature across disordered eating behaviours. However, there has been limited research on the transdiagnostic nature of LOC in this area. The primary aim of this study was to systematically review disordered eating behaviours and measures of LOC in clinical and non-clinical populations.
Electronic searches of the relevant databases were conducted. Selected articles were screened for eligibility and assessed for methodological quality.
Thirty-four studies met inclusion criteria. Findings demonstrated that LOC was associated with disordered eating behaviours across bariatric populations, eating disorder populations, and community populations. Specifically, LOC was associated with binge eating (subjective and objective episodes), grazing, night eating, and emotional or stress eating. Findings also revealed that LOC was inconsistently operationalised across studies, with varied approaches to measuring the construct.
Overall, the findings from this review provide support for LOC as a transdiagnostic feature of disordered eating behaviours. Future studies should utilise robust multi-method assessments to measure the severity of LOC, which may provide greater insight into how LOC manifests across different eating disorder presentations.
新出现的证据表明，失控（LOC）可能是饮食失调行为的共同特征。然而，在这一领域，关于 LOC 的跨诊断性质的研究有限。本研究的主要目的是系统地综述临床和非临床人群中饮食失调行为和 LOC 测量。
对相关数据库进行电子检索。对入选的文章进行筛查，以确定其是否符合纳入标准并评估其方法学质量。
34 项研究符合纳入标准。研究结果表明，LOC 与肥胖人群、饮食失调人群和社区人群中的饮食失调行为有关。具体而言，LOC 与暴食（主观和客观发作）、贪食、夜间进食、情绪或应激进食有关。研究结果还表明，LOC 在不同的研究中被不一致地操作化，对该结构的测量方法也各不相同。
总的来说，本综述的研究结果为 LOC 作为饮食失调行为的跨诊断特征提供了支持。未来的研究应采用可靠的多方法评估来测量 LOC 的严重程度，这可能更深入地了解 LOC 在不同饮食失调表现中的表现。
