Although childhood maltreatment is a well-established risk factor for a multitude of poor psychosocial outcomes, considerably less is known about mechanisms driving this risk transmission. Recent theoretical models posit that types of childhood maltreatment (deprivation vs. threat) may lead to alterations in reward and emotional processing that confer risk for later psychosocial problems. However, empirical examination of these theories is currently limited. We used a person-centered approach to identify profiles of reward and emotional processing in a sample of 758 adults reporting elevated childhood maltreatment. Latent profile analysis indicated a 3-class solution best fit the data: a blunted reward class ( = 220; 29.0%) characterized by low reward processing and average emotional processing; a disrupted emotional processing class ( = 242; 31.9%) marked by normative levels of reward processing but high emotional pain and experiential avoidance and low distress tolerance; and an emotional resilience class (n = 296; 39.1%) characterized by normative reward and emotional processing. Consistent with theoretical models, the specificity of disruption was differentially associated with dimensions of childhood maltreatment, with individuals in the blunted reward class reporting more childhood neglect and individuals in the disrupted emotional processing class reporting more childhood physical/sexual abuse. These profiles of disrupted reward and emotional processing also showed differential relations with the frequency and affective motivations for lifetime substance use. Findings provide empirical support for novel conceptual models of childhood maltreatment that focus on the consequences that may represent mechanisms for problematic behaviors like substance use.

尽管童年期受虐是众多不良心理社会后果的一个既定风险因素,但对于驱动这种风险传递的机制,我们所知甚少。最近的理论模型认为,童年期受虐的类型(剥夺与威胁)可能会导致奖赏和情绪加工的改变,从而带来日后出现心理社会问题的风险。然而,目前对这些理论的实证检验还很有限。我们采用以个体为中心的方法,在758名报告童年期受虐程度较高的成年人样本中,确定奖赏和情绪加工的特征。潜在类别分析表明,三类解决方案最适合这些数据:一类是奖赏钝化型(n = 220;29.0%),其特征是奖赏加工水平低,情绪加工水平中等;一类是情绪加工紊乱型(n = 242;31.9%),其特点是奖赏加工水平正常,但情绪痛苦程度高、存在经验性回避且痛苦耐受力低;还有一类是情绪复原型(n = 296;39.1%),其特征是奖赏和情绪加工水平正常。与理论模型一致,破坏的特异性与童年期受虐的维度存在差异关联,奖赏钝化型的个体报告更多童年期忽视,而情绪加工紊乱型的个体报告更多童年期身体虐待/性虐待。这些奖赏和情绪加工受损的特征还与终生物质使用的频率和情感动机存在差异关系。研究结果为童年期受虐的新理论模型提供了实证支持,这些模型关注的后果可能是物质使用等问题行为的机制。(《心理学文摘数据库记录》(c)2022美国心理学会,保留所有权利)
