Internalizing symptoms are the most prevalent mental health problem in adolescents, with sharp increases seen, particularly for girls, and evidence that young people today report more problems than previous generations. It is therefore critical to measure and monitor these states on a large scale and consider correlates. We used novel panel network methodology to explore relationships between internalizing symptoms, well-being, and inter/intrapersonal indicators. A multiverse design was used with 32 conditions to consider the stability of results across arbitrary researcher decisions in a large community sample over three years (N = 15,843, aged 11–12 at Time 1). Networks were consistently similar for girls and boys. Stable trait-like effects within anxiety, attentional, and social indicators were found. Within-person networks were densely connected and suggested mental health and inter/intrapersonal correlates related to one another in similar complex ways. The multiverse design suggested the particular operationalization of items can substantially influence conclusions. Nevertheless, indicators such as thinking clearly, unhappiness, dealing with stress, and worry showed more consistent centrality, suggesting these indicators may play particularly important roles in the development of mental health in adolescence.

内化症状是青少年中最普遍的心理健康问题，出现了急剧增加，尤其是对女孩而言，并且有证据表明，今天的年轻人比前几代人报告的问题更多。因此，大规模测量和监控这些状态并考虑相关性至关重要。我们使用新颖的面板网络方法来探索内化症状、幸福感和人际/内在指标之间的关系。使用具有 32 个条件的多元宇宙设计来考虑三年内大型社区样本中任意研究人员决策的结果稳定性（N= 15,843，时间 1 为 11-12 岁）。女孩和男孩的网络始终相似。在焦虑、注意力和社交指标中发现了稳定的特质效应。人际网络紧密相连，表明心理健康和人际/人际关联以类似的复杂方式相互关联。多元宇宙设计表明，项目的特定操作化可以极大地影响结论。然而，清晰思考、不快乐、应对压力和担忧等指标显示出更加一致的中心性，这表明这些指标可能在青春期心理健康的发展中发挥特别重要的作用。
