This study examined daily links between sibling warmth and negativity and positive and negative mood in middle childhood and the moderating role of enculturation. Participants were 326 Latinx children from 163 families in the United States (M_age = 10.63 and 8.58 years for older and younger siblings, 48.5% female, 89.3% Mexican-origin). Children reported their days’ experiences during seven nightly phone interviews conducted in 2018–2019. Multilevel analyses revealed within-person, positive associations between daily sibling warmth and positive mood $\begin{array}{c}(\mathrm{OR}=1.81,95\%\mathrm{CI}=[1.25,2.62])\hfill \end{array}$, and sibling negativity and negative mood $(\mathrm{OR}=3.21,95\%\mathrm{CI}=[2.12,4.86])$. Moreover, for more enculturated children, odds of positive mood were lower on days when they experienced more sibling negativity than usual. Findings document the significance of Latinx children's daily sibling experiences.

拉丁裔兄弟姐妹的关系质量和情绪之间的日常联系

这项研究探讨了童年中期兄弟姐妹的温暖与消极、积极与消极情绪之间的日常联系以及文化适应的调节作用。参与者是来自美国 163 个家庭的 326 名拉丁裔儿童（中_号 = 10.63 岁，年长和年幼的兄弟姐妹为 8.58 岁，其中 48.5% 为女性，89.3% 为墨西哥裔）。孩子们在 2018 年至 2019 年进行的七次夜间电话采访中报告了他们一天的经历。多层次分析揭示了日常兄弟姐妹温暖与积极情绪之间的人与人之间的积极联系$\begin{array}{c}（\mathrm{或者}=1.81,95\%\mathrm{CI}=[1.25,2.62]）\hfill \end{array}$，以及兄弟姐妹的消极情绪和消极情绪$（\mathrm{或者}=3.21,95\%\mathrm{CI}=[2.12,4.86]）$。此外，对于文化程度较高的孩子来说，当他们比平时经历更多的兄弟姐妹消极情绪时，他们保持积极情绪的几率就会降低。研究结果记录了拉丁裔儿童日常兄弟姐妹经历的重要性。
