目的：在体重指数（BMI）较高的青少年中，失控和暴饮暴食很常见。正念可能影响消极情绪，两者都可能与失控和暴饮暴食有关。然而，在青少年的日常生活中，人们对这些联系的了解有限。方法45名体重高的青少年（77%为女性，年龄= 14.4岁，年龄= 1.7岁）（92% BMI [kg/m2]≥85百分位数的年龄/性别）每天重复测量正念、负面情绪、失控和暴饮暴食约7天（M= 5.6天，范围= 1-13天）。进行多水平混合建模，以测试当日（并发）和次日（时间顺序/预期）的人内（个体内）和人间（个体间）关联。结果在同一天和第二天，较高的正念与较低的负性情绪存在人内部和人之间的关联。更大的人间正念与青少年发生失控（同一天）的几率较低相关，相反，对饮食的控制更强（同一天和第二天）。更大的人内正念与第二天暴饮暴食的可能性有关。讨论正念、负面情绪和饮食之间存在动态关系，这些关系存在于体重增加风险的青少年中。正念可能是失控和暴饮暴食的一个重要因素。在实验设计中使用瞬时数据的未来工作将有助于解开增加正念/减少对饮食失调的负面影响的个人内部影响。失去控制和暴饮暴食在高体重青少年中很常见。更多的正念——当下，非评判性的注意力——和更少的负面情绪可能与更健康的饮食有关，但我们不知道这些过程如何在青少年的日常生活中发挥作用。为了解决这一知识差距，目前的研究结果表明，更大的日常正念，而不是负面影响，与更少的失控/暴饮暴食有关，这表明正念对青少年日常生活中饮食模式的重要性。
ObjectiveLoss‐of‐control and overeating are common in adolescents with high body mass index (BMI). Mindfulness may affect negative affect, and both may relate to loss‐of‐control and overeating. Yet, there is limited understanding of these associations in adolescents' daily lives.MethodsForty‐five adolescents (77% female;Mage= 14.4 years,SDage= 1.7 years) with high weight (92% with BMI [kg/m2] ≥85th percentile for age/sex) provided daily, repeated measurements of mindfulness, negative affect, loss‐of‐control, and overeating for ~7 days (M= 5.6 days; range = 1–13). Multilevel mixed modeling was conducted to test within‐person (intraindividual) and between‐person (interindividual) associations for the same‐day (concurrent) and next‐day (time‐ordered/prospective).ResultsThere were within‐person and between‐person associations of higher mindfulness with lower negative affect on the same‐day and next‐day. Greater between‐person mindfulness related to lower odds of adolescents' loss‐of‐control occurrence (same‐day) and conversely, more perceived control over eating (same‐day and next‐day). Greater within‐person mindfulness related to less odds of next‐day overeating.DiscussionDynamic relations exist among mindfulness, negative affect, and eating in adolescents at‐risk for excess weight gain. Mindfulness may be an important element to consider in loss‐of‐control and overeating. Future work using momentary‐data within an experimental design would help disentangle the intraindividual effects of increasing mindfulness/decreasing negative affect on disordered eating.Public SignificanceLoss‐of‐control and overeating are common in teenagers with high weight. Greater mindfulness—present‐moment, non‐judgmental attention—and less negative emotions may relate to healthier eating, but we do not know how these processes play out in teenagers' daily lives. Addressing this knowledge gap, the current findings showed that greater daily mindfulness, but not negative affect, related to less loss‐of‐control/overeating, suggesting the importance of mindfulness for eating patterns in teenagers' daily lives.
