背景 先前的研究表明，饮食失调患者的改变动机低与不良治疗结果之间存在关联。因此，各种研究探讨了动机增强疗法（MET）对饮食失调的改变动机和治疗结果的影响。在每项研究中，MET 都是在面对面的环境中进行的。然而，由于其匿名性和易于访问性，互联网作为此类干预的形式提供了多种优势。因此，本研究调查了基于互联网的计划（ESS-KIMO'）对增强改变饮食失调的动力的效果。 方法 总共 212 名女性被接受参与，并随机分配到干预条件（n = 103）或等待列表控制条件（n = 109）。干预包括六次在线 MET 会议。参与者分别在干预或等待期之前和之后完成了饮食失调检查问卷（EDE-Q）、饮食失调变化阶段问卷（SOCQ-ED）、饮食失调利弊量表（P-CED）、自我效能量表（SES）和罗森伯格自尊量表（RSES）。共有 125 名参与者完成了治疗后评估。进行了更完整的分析和意向治疗分析。结果发现了显着的时间组相互作用，表明与对照组相比，干预组从治疗前到治疗后的一些措施的症状有更强的减轻，动机方面和自尊方面有更强的增加。结论基于互联网的方法可以被认为有助于增强改变饮食失调的动机和产生初步症状改善。
Background Previous research has demonstrated an association between low motivation to change and an unfavorable treatment outcome in patients with an eating disorder. Consequently, various studies have examined the effects of motivational enhancement therapy (MET) on motivation to change and treatment outcome in eating disorders. In each of these studies, MET was administered in a face-to-face setting. However, because of its anonymity and ease of access, the internet provides several advantages as the format for such an intervention. Therefore, the current study investigated the effects of an internet-based program (ESS-KIMO') to enhance motivation to change in eating disorders.Method In total, 212 females were accepted for participation and assigned randomly to the intervention condition (n=103) or waiting-list control condition (n=109). The intervention consisted of six online MET sessions. Before and after the intervention or waiting period respectively, participants completed the Eating Disorder Examination Questionnaire (EDE-Q), the Stages of Change Questionnaire for Eating Disorders (SOCQ-ED), the Pros and Cons of Eating Disorders Scale (P-CED), the Self-Efficacy Scale (SES), and the Rosenberg Self-Esteem Scale (RSES). A total of 125 participants completed the assessment post-treatment. Completer analyses and intent-to-treat analyses were performed.Results Significant timexgroup interactions were found, indicating a stronger increase in motivational aspects and self-esteem, in addition to a stronger symptom reduction on some measures from pre- to post-treatment in the intervention group compared to the control group.Conclusions Internet-based approaches can be considered as useful for enhancing motivation to change in eating disorders and for yielding initial symptomatic improvement.
