Despite abundant evidence of the detrimental effects of childhood adversity, its nature and underlying mechanisms remain contested. One influential theory, the , proposes deprivation and threat as distinct dimensions of early experience. In this preregistered analysis of data from the Avon Longitudinal Study of Parents and Children (ALSPAC), we used a network and clustering approach to assess the dimensionality of relationships between childhood adversity and adolescent cognition and emotional functioning, and we used recursive partitioning to identify timing effects. We found evidence that deprivation and threat are separate dimensions of adversity and that early experiences of deprivation cluster with later measures of cognition and emotional functioning. This cluster varies by age of exposure; it includes fewer forms of deprivation as children grow from infancy to middle childhood. Our measures did not form a specific cluster linking threat to emotional functioning.
尽管有大量证据表明儿童逆境的不良影响,但它的性质和潜在机制仍存在争议。一个有影响力的理论,即,提出剥夺和威胁是早期经验的两个不同维度。在对父母和孩子纵向研究(ALSPAC)的数据进行预先注册的分析中,我们使用网络和聚类方法来评估儿童逆境与青少年认知和情绪功能之间关系的维度,并使用递归分区来识别时间效应。我们有证据表明,剥夺和威胁是逆境的两个不同维度,而且早期的剥夺经历与后来的认知和情绪功能测量结果相关。这个集群因暴露年龄而异;随着儿童从婴儿期到儿童中期的成长,它包含的剥夺形式较少。我们的测量方法没有形成一个特定的集群,将威胁与情绪功能联系起来。
