目的越来越多的研究试图了解情绪和饮食行为之间的关系。生态瞬时评估（EMA）方法提供了一种在自然环境中评估这些过程的方法。我们使用 EMA 来检查患有亚临床饮食行为失调的女性的日常生活中情绪与饮食行为之间的关系。方法参与者（N = 127，年龄 M = 19.6 岁，BMI M = 25.5）在掌上电脑上完成了 1 周的 5 份每日 EMA 报告。评估包括进食期间的负面情绪（NA）和进食相关行为（吃大量食物、对进食失去控制和限制食物摄入量）和不进食发作（不进食以控制体重/体型）。时滞多级模型测试了情绪与饮食行为之间的关系。结果较高的 NA 并不先于任何不健康的饮食和体重控制行为。然而，当女性报告在最近的饮食期间吃了大量食物、失去对饮食的控制和限制食物摄入时，NA 较高，但在不吃东西以控制体重/体形后则NA 较高。讨论这些发现阐明了日常生活中可能影响不健康饮食和体重控制行为的发展和维持的过程，反过来，这些过程可以为干预措施提供信息。 (c) 2014 年 Wiley periodicals, Inc.（Int J Eat Disord 2014；47:853-859）
ObjectiveA growing body of research seeks to understand the relationship between mood and eating behaviors. Ecological Momentary Assessment (EMA) methods provide a method for assessing these processes in natural settings. We used EMA to examine the relationship between mood and eating behaviors in everyday life among women with subclinical disordered eating behaviors.MethodParticipants (N=127, age M=19.6 years, BMI M=25.5) completed five daily EMA reports on palmtop computers for 1 week. Assessments included measures of negative affect (NA) and eating-related behavior during eating (eating large amounts of food, loss of control over eating, and restricting food intake) and noneating episodes (skip eating to control weight/shape). Time-lagged multilevel models tested mood-eating behavior relationships.ResultsHigher NA did not precede any unhealthy eating and weight control behaviors. However, NA was higher when women reported eating large quantities of food, losing control over eating, and restricting food intake during their most recent eating episode, but not after skipping eating to control weight/shape.DiscussionThese findings elucidate the processes in daily life that may influence the development and maintenance of unhealthy eating and weight control behaviors that, in turn, can inform interventions.
