方法采用生态瞬时评估（EMA）方法，通过移动的手机日记，记录一组节食者的饮食失误发生情况（N=80; M-age=41.21+/-15.60 years; M-BMI=30.78+/-7.26）。结果分析表明，饮食诱惑的强度、他人的存在、应对反应和环境与失误呈正相关（暴露于食物线索）;失误更有可能发生在晚上，并与应对机制的使用呈负相关。此外，失效的发生被发现调解上述预测因素之间的关系的失效和自我效能，以抵御未来的饮食temptations.Conclusions结果提供了一个深入了解的发生失误的节食者，并有影响的干预措施，侧重于减肥维护和复发预防。
Purpose The aim of this study is to investigate the factors related to dietary lapse occurrence in a community sample of dieters.Methods An ecological momentary assessment (EMA) methodology, via mobile phone-based diaries, was employed to record dietary lapse occurrences in a group of dieters (N=80; M-age=41.21+/-15.60 years; M-BMI=30.78+/-7.26) over 7 days.Results Analyses indicated that lapses were positively associated with the strength of dietary temptation, presence of others, coping responses, and the environment (exposure to food cues) in which the dieters were in; lapses were more likely to occur in the evening and were negatively associated with the use of coping mechanisms. Additionally, lapse occurrence was found to mediate the relationships among the above predictors of lapse and the self-efficacy to resist future dietary temptations.Conclusions Results provide an insight into the occurrence of lapses in dieters and have implications for interventions focusing on weight loss maintenance and relapse prevention.
