Latinx students experience stress at higher rates than European-American college-students in the U.S. and report the highest levels of anxiety among all other college-students, which can be a potential barrier to success. However, family members are identified as important sources of support by Latinx young-adults, and feeling support from family indicates a higher likelihood to remain enrolled in college. Few studies have explored the role of siblings in this relationship. This study examined whether positive and negative relationship qualities (RQ) between Latinx siblings may interact with level of anxiety, predicting academic stress (AS) and future aspirations (FA). Findings indicated that younger siblings with high anxiety and high negative RQ experienced higher levels of AS, while older siblings with low or mean-level anxiety and high negative RQ experienced high AS. Younger siblings with low anxiety, and high negative RQ with older siblings experienced low FA. The findings provide evidence that sibling relationship quality in Latinx students moderates the associations with anxiety, academic stress, and future aspirations, and that the presence of negative relationship qualities carried particular implications for future aspirations and academic stress. Understanding the influence of Latinx sibling RQ on mental health and AS can offer insight into the role of sibling relationships in the context of health, academic retention, and success in Latinx young people.

在美国，拉丁裔学生比欧洲裔美国大学生承受压力的比例更高，并且在所有其他大学生中焦虑程度最高，这可能是成功的潜在障碍。然而，家庭成员被拉丁裔年轻人视为重要的支持来源，感受到家庭的支持表明继续上大学的可能性更高。很少有研究探讨兄弟姐妹在这种关系中的作用。这项研究探讨了拉丁裔兄弟姐妹之间的积极和消极关系质量（RQ）是​​否可能与焦虑水平相互作用，从而预测学业压力（AS）和未来愿望（FA）。研究结果表明，具有高度焦虑和高负 RQ 的弟弟妹妹经历了较高水平的 AS，而具有低或平均水平焦虑和高负 RQ 的年长兄弟姐妹经历了高 AS。焦虑程度较低且与年长兄弟姐妹的负 RQ 较高的弟弟妹妹的 FA 较低。研究结果证明，拉丁裔学生的兄弟姐妹关系质量可以调节与焦虑、学业压力和未来愿望的关联，并且消极关系质量的存在对未来愿望和学业压力具有特殊的影响。了解拉丁裔兄弟姐妹的 RQ 对心理健康和 AS 的影响可以帮助我们深入了解兄弟姐妹关系在拉丁裔年轻人的健康、学业保留和成功方面的作用。
