Disordered eating cognitions and behaviours in childhood and adolescence have been identified as precursors for the development of eating disorders. Another important contributor to eating disorder risk is maladaptive emotion regulation. However, while the regulation of negative affect has been the focus of much research, the literature on the role of positive emotion regulation in eating pathology is extremely limited. The present study extends previous research by examining the regulation of both positive and negative affect in disordered eating using two waves of a daily diary design.
Every evening for 21 days, 139 youths (8-15 years) reported their use of rumination, dampening, and disordered eating cognitions and behaviours. 1 year later, during the onset of the COVID-19 pandemic, 115 of these youths were followed-up.
As predicted, higher levels of rumination and dampening were found to be associated with a higher frequency of weight concerns and restrictive eating on person-level (both Waves) and day-level (Wave 2). Further, a higher frequency of rumination at Wave 1 predicted increases in the frequency of restrictive eating 1 year later.
Our findings underline the importance of examining regulation of both positive and negative emotion in order to understand eating disorder risk.
儿童和青少年时期的饮食失调认知和行为已被确定为饮食失调发展的前兆。另一个导致饮食失调风险的重要因素是适应不良的情绪调节。然而，尽管负面情绪的调节一直是许多研究的重点，但关于积极情绪调节在饮食病理学中的作用的文献却极为有限。本研究通过使用每日日记设计的两个波次来扩展之前关于使用失调饮食来调节积极和消极情绪的研究。
在 21 天的时间里，每天晚上，139 名青少年（8-15 岁）报告了他们的反刍、抑制和饮食失调认知和行为的使用情况。1 年后，在 COVID-19 大流行开始时，其中 115 名青少年接受了随访。
正如预测的那样，较高的反刍和抑制水平与个体水平（两个波次）和日水平（波次 2）上更高的体重担忧和限制进食频率相关。此外，波次 1 时更高的反刍频率预测了 1 年后限制进食频率的增加。
我们的发现强调了检查积极和消极情绪调节的重要性，以了解饮食失调风险。
