智利儿童队列：疫情前后3至6岁心理健康的多轨迹与风险因素
Early childhood mental health in the wake of COVID-19: Multitrajectories and risk factors from a longitudinal Chilean cohort
一项智利儿童纵向队列研究（N=468，48.9%为女孩，19.2%的母亲为移民）追踪了3至6岁儿童在新冠疫情前、中、后三个时期的心理健康轨迹，依据摘要，基于组别的多轨迹模型识别出五种特征：三类低症状组（82.9%）和两类较高风险组（17.1%），后者表现为持续或不断升级的内化与外化问题共现。
This longitudinal study examined mental health trajectories in a Chilean child cohort ( N = 468, 48.9% girls; 19.2% children of migrant mothers) from ages three to six, spanning the pre-, during-, and post-COVID-19 periods. Group-based multitrajectory modeling identified five profiles: three lower-symptom (82.9%) and two higher-risk groups (17.1%), characterized by persistent or escalating co-occurring internalizing and externalizing problems. Early high symptoms predicted continued difficulties through age 6. Prepandemic negative affect and maternal depressive symptoms were early risk factors, while COVID-related stressors—hostile parenting and income loss—predicted higher-risk group membership. Maternal mental health deterioration further contributed to symptom escalation. Findings highlight the heterogeneity of early childhood mental health postpandemic and the need for early identification of psychosocial risk factors.
