目标：尽管人们对制定个性化体重管理计划的兴趣日益浓厚，但对于哪些因素最能预测体重变化却知之甚少。方法：本研究调查了 74 名成年人在为期 3 个月的基于互联网的行为减肥计划和随后的 9 个月的“维持”期（在此期间不提供额外干预）中体重减轻和恢复的近端（每周）预测因素。参与者被要求每天使用通过蜂窝网络传输体重的秤进行自我称重，并每周回答一份简短的问卷，询问假设与体重减轻和恢复有关的情绪、行为和认知。结果：纵向多层次模型表明，初始干预期间的体重减轻可以通过以下因素近乎预测：（a）自我监测体重和热量摄入的频率更高，饮食选择和减肥目标之间的一致性，以及“保持正轨”实现这些目标的重要性，以及（b）更少的负面情绪，对体重控制努力的厌倦，饥饿和吃“不按计划”食物的诱惑（ps）
Objectives: Despite increased interest in the development of individually tailored weight management programs, little is known about what factors proximally predict weight change. Method: The current study investigated proximal (week-to-week) predictors of weight loss and regain in 74 adults during a 3-month, Internet-based behavioral weight loss program followed by a 9-month "maintenance" period (during which no additional intervention was provided). Participants were asked to self-weigh daily using scales that transmitted weight via the cellular network and to answer a brief questionnaire each week querying mood, behaviors, and cognitions hypothesized to be associated with weight loss and regain. Results: Longitudinal multilevel models demonstrated that weight loss during initial intervention was proximally predicted by (a) greater frequency of self-monitoring weight and caloric intake, consistency between eating choices and weight loss goals, and importance of "staying on track" with these goals and (b) less negative mood, boredom with weight control efforts, hunger, and temptation to eat foods "not on plan" (ps
