目标:在青少年中,抑制饮食和焦虑通常同时发生。因此,针对导致饮食抑制和焦虑的独特机械脆弱性的精确干预方法可能会有所帮助。然而,这种干预措施的有效性取决于与不节制饮食有关的人与人之间的联系的知识,焦虑,和相关的过程。
方法:对39名焦虑升高且体重高于平均水平(BMI%ile≥75)的青春期女性(12-17岁)的样本完成了理论驱动的社会和认知行为变量的测量,禁止进食,通过7天以上的生态瞬时评估和焦虑。使用混合效应模型分析数据。
结果:社会压力源的人与人之间的差异与情绪饮食有关,在没有饥饿的情况下吃饭,和焦虑,而人与人之间消极想法的差异与所有不受抑制的饮食变量和焦虑有关。避免的人之间的差异与任何结果无关。此外,社会压力源和消极想法的人与人之间的差异,以及社会压力源的人与人之间的偏差(与人的平均水平),消极的想法,和回避-与焦虑有关。反过来,在没有饥饿和情绪饮食的情况下,人与人之间的焦虑差异预测了饮食,在任何给定的时间点,人内焦虑的偏差与情绪饮食有关。
结论:研究结果支持了抑制进食的人际关系和认知行为模型。对焦虑的不同触发效应,无论是在人与人之间,焦虑和所有饮食相关结果之间的显著关联,强调针对个体对焦虑触发因素敏感性差异的干预措施的潜在效用。
■研究结果为抑制饮食的人际和认知行为模型提供了支持,强调焦虑是一种突出的脆弱性和潜在的机制因素,是抑制饮食的基础。社会,认知,行为变量与参与者的焦虑有差异,根据青少年对焦虑的敏感性,提出未来干预调整和干预选择的可能性,以作为抑制饮食行为的触发因素。
OBJECTIVE: Among adolescents, disinhibited eating and anxiety commonly co-occur. Precision intervention approaches targeting unique mechanistic vulnerabilities that contribute to disinhibited eating and anxiety may therefore be helpful. However, the effectiveness of such interventions hinges on knowledge of between- and within-person associations related to disinhibited eating, anxiety, and related processes.
METHODS: A sample of 39 adolescent females (12-17 years) with elevated anxiety and above-average weight (BMI %ile ≥ 75th) completed measures of theoretically driven social and cognitive-behavioral variables, disinhibited eating, and anxiety via ecological momentary assessment over 7 days. Data were analyzed using mixed-effects models.
RESULTS: Between-person differences in social stressors were linked to emotional eating, eating in the absence of hunger, and anxiety, whereas between-person differences in negative thoughts were associated with all disinhibited eating variables and anxiety. Between-person differences in avoidance were not related to any outcome. Additionally, between-person differences in social stressors and negative thoughts-as well as within-person deviations (from person-average levels) of social stressors, negative thoughts, and avoidance-were associated with anxiety. In turn, between-person differences in anxiety predicted eating in the absence of hunger and emotional eating, and within-person deviations in anxiety were associated with emotional eating at any given time point.
CONCLUSIONS: Findings support elements of both the
interpersonal and cognitive-behavioral models of disinhibited eating. Differential trigger effects on anxiety, both at the between- and within-person levels, and significant associations between anxiety and all eating-related outcomes, highlight the potential utility of interventions targeting individual differences in sensitivity to anxiety triggers.
UNASSIGNED: Findings provide support for the
interpersonal and cognitive-behavioral models of disinhibited eating, highlighting anxiety as a salient vulnerability and potential mechanistic factor underlying disinhibited eating. Social, cognitive, and behavioral variables were differentially related to anxiety across participants, suggesting potential for future intervention tailoring and intervention selection based on adolescents\' sensitivity to anxiety as a trigger for disinhibited eating behavior.
