情感不稳定在青春期很常见，但在高水平上它与各种内化和外化障碍有关，包括饮食失调。尽管大多数模型都将情感强度作为解释成人饮食失调的机制，但情感不稳定在预测青少年饮食行为方面可能更具发展相关性。本手稿利用生态瞬时评估，在两项独立的研究中探讨了饮食失控（LOC）（青少年饮食失调的关键组成部分）与超重/肥胖青少年的情感不稳定之间的关联，其中一项针对儿童中期和青春期早期的青少年（研究 1：8 至 13 岁），另一项针对青春期早期至中期的青少年（研究 2：12-17 岁）。总体而言，研究 1 中情感不稳定与 LOC 之间没有关联，但在研究 2 中，年龄调节了积极情感不稳定与 LOC 之间的关联，因此，人与人之间积极情感不稳定（即相对于同龄人）越大，青春期早期青少年的平均 LOC 越低，而青春期后期青少年的平均 LOC 越高。在研究 2 中，消极情感不稳定也与 LOC 相关，因此，当青少年报告的人内消极情感不稳定（即相对于他们自己的平均水平）较少的日子里，他们也报告了较高的平均 LOC。这两项研究的结果表明，情感不稳定与 LOC 之间的关联可能要到青春期才会出现，而当出现这种关联时，积极和消极的情感不稳定可能都是需要考虑的重要因素。
Affective instability is common during adolescence, but at high levels it is associated with a variety of internalizing and externalizing disorders, including eating disorders. Although most models focus on affective intensity as a mechanism for explaining eating disorders in adults, affective instability may be more developmentally relevant at predicting eating behaviors in youth. Using ecological momentary assessment, this manuscript explored the association between loss of control over eating (LOC), a key component of dysregulated eating in youth, and affective instability in youth with overweight/obesity in two separate studies, one with youth in middle childhood and early adolescence (Study 1: ages eight to 13) and one in youth in early through middle adolescence (Study 2: ages 12–17). Overall, there was no association between affective instability and LOC in Study 1, but in Study 2, age moderated the association between positive affective instability and LOC, such that greater between-person positive affective instability (i.e., relative to peers) was associated with lower average LOC for youth earlier in adolescence and higher average LOC for those later in adolescence. Negative affective instability was also associated with LOC in Study 2, such that on days when youth reported less within-person negative affective instability (i.e., relative to their own average), they also reported greater average LOC. Findings across the two studies indicate that the association between affective instability and LOC may not emerge until adolescence, and when it does, both positive and negative affective instability may be important to consider.
