To better understand early etiological pathways to trajectories of child exposure to community violence (CECV), we used person-centered latent class growth analysis (LCGA) to examine chronicity of CECV from early school age through early adolescence, and examined early risks of the identified CECV trajectories (i.e., prenatal cocaine exposure, harsh parenting and caregiving instability across infancy and early childhood, and child activity level and inhibitory control at kindergarten age).
An at-risk sample (N = 216; 110 girls) of primarily low-income participants (76% on Temporary Assistance for Needy Families) with high rates of prenatal substance exposure was used. The majority of the mothers were African American (72%), had high school or below education (70%), and were single (86%). Postnatal assessments occurred at eight time points during infancy and toddlerhood, early childhood through early school age, and early adolescence.
We identified two distinct linearly increasing CECV trajectories (high-exposure and low-exposure). An interaction between child activity level and maternal harshness emerged, such that children with high activity levels and experiencing high harshness had the highest probabilities of being in the high exposure-increasing trajectory, in addition to early caregiving instability (conditional effect).
The current findings not only have important theoretical implications but also provide insights into early intervention.
为了更好地理解儿童接触社区暴力(CECV)轨迹的早期病因途径,我们采用以人为中心的潜在类别增长分析(LCGA)来研究从学龄早期到青春期早期CECV的慢性情况,并研究已确定的CECV轨迹的早期风险(即产前可卡因暴露、婴儿期和幼儿期的严厉养育和照料不稳定,以及幼儿园年龄时的儿童活动水平和抑制控制)。
使用了一个高危样本(N = 216;110名女孩),主要是低收入参与者(76%领取贫困家庭临时援助),产前物质暴露率很高。大多数母亲是非裔美国人(72%),教育程度为高中或以下(70%),且为单身(86%)。产后评估在婴儿期和幼儿期、幼儿期到学龄早期以及青春期早期的八个时间点进行。
我们确定了两条不同的线性增加的CECV轨迹(高暴露和低暴露)。儿童活动水平与母亲严厉程度之间出现了一种相互作用,即活动水平高且经历高严厉程度的儿童除了早期照料不稳定外(条件效应),处于高暴露增加轨迹的概率最高。
当前研究结果不仅具有重要的理论意义,还为早期干预提供了见解。
