There is substantial variability in weight loss outcomes. Psychosocial characteristics underlying outcomes require better understanding, particularly on self-managed digital programs. This cross-sectional study examines differences in psychosocial characteristics by weight loss and engagement outcome, and which characteristics are most associated with weight loss, on a self-managed digital weight loss program. Some underexplored psychosocial characteristics are included, such as flourishing, or a sense of meaning and purpose in life. A questionnaire was emailed to a random sample of 10,000 current users at week 5 in the program and 10,000 current users at week 17. The questionnaire was completed by 2225 users, and their self-reported weight and recorded program engagement data were extracted from the program's database. Multiple comparison tests indicated that mental health quality of life, depression, anxiety, work-life balance, and flourishing differed by weight loss outcome at program end (week 17; ≥5%, 2-5%, below 2%) and by engagement tertile at program beginning and end (weeks 5 and 17). Only anxiety was associated with weight loss in a backward stepwise regression controlling for engagement and sociodemographic characteristics. Flourishing did not predict weight loss overall but predicted the weight loss outcome group. Our findings have implications for creating more effective interventions for individuals based on psychosocial characteristics and highlight the potential importance of anxiety in underexplored self-managed digital programs.
减肥效果存在很大差异。需要更好地了解导致这种差异的心理社会特征，尤其是在自我管理的数字项目中。本横断面研究通过自我管理数字减肥计划，检查了减肥和参与结果的心理社会特征差异，以及哪些特征与减肥最相关。研究纳入了一些尚未充分探讨的心理社会特征，如繁荣，或对生活意义和目标的感知。在该计划的第 5 周和第 17 周，向 10000 名当前用户随机发送了一份电子邮件调查问卷，共有 10000 名当前用户参与。2225 名用户完成了问卷，他们的自我报告体重和记录的程序参与数据从程序数据库中提取。多项比较测试表明，心理健康生活质量、抑郁、焦虑、工作-生活平衡和繁荣在项目结束时（第 17 周；减重≥5%、2-5%、<2%）和项目开始和结束时的参与三分位数（第 5 周和第 17 周）存在差异。只有焦虑在控制参与度和社会人口学特征的情况下，与减重呈显著相关。在整体减重中，繁荣并未预测减重结果，但预测了减重结果的组别。我们的研究结果为基于心理社会特征为个人创造更有效的干预措施提供了依据，并强调了焦虑在自我管理的数字项目中具有潜在的重要性。
