Dysregulated eating behaviors, comprising subthreshold and clinical binge-eating disorder (BED) and bulimia nervosa (BN), are increasing among the general population, with a consequent negative impact on one's health and well-being. Despite the severity of these outcomes, people with BED and BN often face a delay in receiving a diagnosis or treatment, often due to difficulties in accessing care. Hence, evidence-based and sustainable interventions for eating symptomatology are needed. The present study aims to assess the effectiveness of a web-based 10-session multidisciplinary group intervention based on Dialectical Behavior Therapy (DBT) for BED and BN, aimed at reducing psychological distress and binge-eating-related symptomatology in a sample of patients with dysregulated eating behaviors and including one session of nutritional therapeutic education. A total of 65 participants (84.6% F; age M = 38.5 ± 13.2; experimental group, N = 43; treatment-as-usual group, TAU, N = 22) took part in the study. The results show, after the 9 weekly sessions, a significant reduction in binge-eating-related symptomatology and general psychopathology and an increased self-esteem and eating self-efficacy in social contexts in the experimental group compared to the treatment-as-usual group (T0 vs. T1). Improvements in the experimental group were significantly maintained after one month from the end of the intervention (T2) in terms of binge-eating symptoms, general psychopathology, and eating self-efficacy in social contexts. This study supports the effectiveness of a brief web-based multidisciplinary group intervention in reducing eating symptomatology and psychological distress and enhancing self-esteem and eating self-efficacy in a group of people with dysregulated eating behaviors. Brief web-based interventions could represent an accessible and sustainable resource to address binge-eating-related symptomatology in public clinical settings.
失调的进食行为，包括阈下和临床暴食障碍（BED）和神经性贪食症（BN），在普通人群中日益增多，对个人的健康和福祉产生了相应的负面影响。尽管这些后果很严重，但 BED 和 BN 患者通常会延迟获得诊断或治疗，这通常是由于难以获得护理。因此，需要基于循证的、可持续的干预措施来治疗进食症状。本研究旨在评估基于辩证行为疗法（DBT）的 10 节网络多学科小组干预措施对 BED 和 BN 的有效性，该措施旨在减少心理困扰和与暴食相关的症状，适用于一组有失调进食行为的患者，并包括一节营养治疗教育课程。共有 65 名参与者（84.6%为女性；年龄 M = 38.5 ± 13.2；实验组 N = 43；常规治疗组 TAU，N = 22）参加了这项研究。结果显示，在 9 周的课程后，实验组与常规治疗组相比，与暴食相关的症状、一般心理病理学以及在社交环境中的自尊和进食自我效能感均显著降低（T0 与 T1）。实验组在干预结束后一个月（T2）时，在暴食症状、一般心理病理学和社交环境中的进食自我效能感方面的改善仍显著保持。本研究支持了一种简短的基于网络的多学科小组干预措施在减少进食症状和心理困扰以及增强失调进食行为患者的自尊和进食自我效能感方面的有效性。简短的基于网络的干预措施可能是公共临床环境中解决与暴食相关的症状的一种可行且可持续的资源。
