The current study examined whether individual differences in depressive and anxious symptoms relate to level of daily self-esteem and instability of daily self-esteem in adolescence. Participants were a racially and ethnically diverse sample of adolescents (79 girls, 65 boys; M age = 13.53 years). Adolescents reported on their depressive and anxious symptoms during a baseline home visit. Then, adolescents reported on their daily self-esteem over the course of 12 consecutive days. Using hierarchical linear modeling analyses, level of daily self-esteem was negatively associated with depressive but not anxious symptoms. In addition, a positive relation emerged between instability of daily self-esteem and depressive symptoms when controlling for level of self-esteem; a similar relation did not emerge for anxious symptoms. The differential findings that emerged between both level and instability of daily self-esteem and depressive versus anxious symptoms may be linked to differences in the temporal orientation of these two types of internalizing symptoms; specifically, depressive symptoms result from backward-looking rumination over previous experiences, whereas anxious symptoms emerge from forward-looking worry about future events (Wenze et al., 2012).

目前的研究检查了抑郁和焦虑症状的个体差异是否与青春期的日常自尊水平和日常自尊的不稳定有关。参与者是不同种族和民族的青少年样本（79 名女孩，65 名男孩；M年龄 = 13.53 岁）。青少年在基线家访期间报告了他们的抑郁和焦虑症状。然后，青少年在连续 12 天的过程中报告了他们的日常自尊。使用分层线性模型分析，日常自尊水平与抑郁症状呈负相关，但与焦虑症状无关。此外，当控制自尊水平时，日常自尊的不稳定性与抑郁症状之间出现了正相关；焦虑症状没有出现类似的关系。日常自尊的水平和不稳定性以及抑郁与焦虑症状之间出现的差异发现可能与这两种内化症状的时间取向差异有关。具体来说，
