The available treatments for people with excess weight have shown small effects. Cognitive training has shown promising results, but most of the research focused on normal-weight university students and reported immediate results after a single training session. This parallel group, randomized, controlled trial aims to study the efficacy of a program for the comprehensive cognitive treatment of excess weight.
Participants will be 150 people with excess weight recruited through social media, who will be randomized into three groups: cognitive intervention, sham cognitive intervention, and treatment as usual. All assessment and intervention sessions will be online in groups of 5-6 participants. The three groups will attend a motivational interviewing session, and they will receive individualized diet and physical exercise guidelines throughout the program. The cognitive training will consist of four weekly sessions of approximately 60-90 min, each based on approach-avoidance bias training, inhibitory control training, implementation of intentions, and episodic future thinking, respectively. The main outcome measure will be a change in Body Mass Index (kg/m). Secondary outcomes include changes in cognitive measures, eating and physical exercise behaviors, and anthropometric measures. Assessments will be conducted up to 6 months after the end of the program. In addition, data on the use of the health system will be collected to analyze the cost-effectiveness and the cost-utility of training. Linear mixed models will be used for statistical analysis. Findings of this study will expand the available evidence on cognitive interventions to reduce excess weight.
现有的超重人群治疗方法效果甚微。认知训练显示出了良好的效果，但大多数研究都集中在正常体重的大学生身上，并且只报告了单次训练后的即时结果。本平行组、随机、对照试验旨在研究超重人群综合认知治疗方案的疗效。
参与者将是通过社交媒体招募的 150 名超重者，他们将被随机分为三组：认知干预组、假认知干预组和常规治疗组。所有评估和干预都将以 5-6 人的小组形式在线进行。三组都将参加动机访谈，并且在整个计划中，他们将获得个性化的饮食和体育锻炼指南。认知训练将包括每周四次，每次约 60-90 分钟，分别基于接近回避偏见训练、抑制控制训练、意图的实施和情景性未来思维。主要结局指标是体重指数（kg/m）的变化。次要结局包括认知测量、饮食和体育锻炼行为以及人体测量学测量的变化。评估将在计划结束后 6 个月内进行。此外，还将收集关于使用卫生系统的数据，以分析培训的成本效益和成本效用。将使用线性混合模型进行统计分析。本研究的结果将扩大现有的认知干预措施来减轻超重的证据。
