Emotions and self-esteem are critical components of well-being and adaptation during adolescence. People differ in their average levels of affect and self-esteem, as well as in how much their affect and self-esteem fluctuate from moment to moment. Fluctuations in affect in particular have not been extensively examined in relation to adolescent-relevant variables. The present study investigates internalizing symptoms, social functioning, and overt and relational aggression as correlates of average levels and within-person variability in daily positive and negative affect (PA and NA) and self-esteem. Crucially, unique association were examined controlling for the other variables. Early adolescents (mean age 10.8 years, N = 94) completed daily diaries across four days on PA, NA, and self-esteem. They also completed general questionnaires, as did peers. Some key findings were that more internalizing symptoms were significantly associated with more variability in NA. The importance of peer relationships for adolescents’ daily mean levels of PA and NA were shown. Peer-perceived social functioning was associated with less fluctuations in self-esteem. Some unexpected, non-significant, findings for aggression appeared. Finally, higher mean NA were associated with more NA fluctuations, whereas higher mean PA and self-esteem were associated with less fluctuations.

青春期早期的日常情感和自尊：平均水平和人内变异性的相关性

情绪和自尊是青春期幸福和适应的重要组成部分。人们在情感和自尊的平均水平以及他们的情感和自尊的波动程度方面存在差异。与青少年相关的变量相关的情感波动尚未得到广泛研究。本研究调查内化症状、社会功能以及公开和关系攻击性与日常积极和消极影响（PA 和 NA）和自尊的平均水平和人内变异性的相关性。至关重要的是，检查了控制其他变量的独特关联。早期青少年（平均年龄 10.8 岁，N = 94）在四天内完成了关于 PA、NA 和自尊的每日日记。他们还完成了一般问卷，同龄人也是如此。一些关键发现是，更多的内化症状与 NA 的更多变异性显着相关。显示了同伴关系对青少年每日平均 PA 和 NA 水平的重要性。同伴感知的社会功能与自尊的波动较小有关。出现了一些出乎意料的、不重要的侵略性发现。最后，更高的平均 NA 与更多的 NA 波动相关，而更高的平均 PA 和自尊与更少的波动相关。不显着，出现了侵略的结果。最后，较高的平均 NA 与更多的 NA 波动相关，而较高的平均 PA 和自尊与较少的波动相关。不显着，出现了侵略的结果。最后，更高的平均 NA 与更多的 NA 波动相关，而更高的平均 PA 和自尊与更少的波动相关。
