Foster children are exposed to high levels of abuse, violence, and other adverse events throughout their childhood and adolescent years. Forms of brain injury, notably traumatic brain injury (TBI), are understudied in the foster child population. This study aimed to explore different forms of brain injury and their cognitive, behavioral, and psychological/emotional effects on current and former foster children using a life course perspective. A thematic analysis with a life course perspective was used to examine semi-structured, open-ended interviews conducted with current and previous foster children between the ages of 16 and 29 years. The study included 47 participants: 25 males (53%) and 22 females (47%) with an average age of 21 years and an average of 11.2 years of education. Of 47 current and previous foster children between the ages of 16 and 29, two-thirds had sustained one or more TBIs. Through a thematic analysis, four overarching and inter-related themes emerged from the data: frequent TBI, normalization (of abuse, violence, injury, and neglect), emotional trauma, and dangerous coping methods such as alcohol use in 94% and recreational drug use in 81%. Normalization of adverse events, emotional trauma, and the use of dangerous coping methods occurred in 66%, 81%, and 49% of participants, respectively, and are the cumulative toxic long-term effects of early negative life experiences and repeated forms of brain injury. Early and continued exposure to TBI, abuse, violence, and/or neglect with continued maladaptive behaviors suggests that the participants may have experienced changes in brain structure and function over their lives that provided the milieu for continued vulnerability to personal and future injury to future generations. These behavioral and perceptual changes point to a toxic combination of injuries that result in continued vulnerability to repeated injury through contextual exposure to risks and maladaptive normalization, emotional trauma, and risky coping styles.
寄养儿童在整个童年和青少年时期都面临着高度的虐待、暴力和其他不良事件。脑损伤的形式,尤其是创伤性脑损伤(TBI),在寄养儿童群体中研究不足。本研究旨在从生命历程的角度探讨不同形式的脑损伤及其对当前和以前的寄养儿童的认知、行为和心理/情感影响。采用生命历程视角的主题分析方法,对16至29岁的当前和以前的寄养儿童进行的半结构化、开放式访谈进行了研究。该研究包括47名参与者:25名男性(53%)和22名女性(47%),平均年龄为21岁,平均受教育年限为11.2年。在47名年龄在16至29岁之间的当前和以前的寄养儿童中,三分之二曾遭受过一次或多次创伤性脑损伤。通过主题分析,数据中出现了四个总体且相互关联的主题:频繁的创伤性脑损伤、(虐待、暴力、伤害和忽视的)常态化、情感创伤以及危险的应对方式,如94%的人饮酒和81%的人使用消遣性药物。不良事件的常态化、情感创伤以及危险应对方式的使用分别发生在66%、81%和49%的参与者中,并且是早期负面生活经历和反复脑损伤形式的累积长期毒性影响。早期和持续暴露于创伤性脑损伤、虐待、暴力和/或忽视以及持续的适应不良行为表明,参与者在其一生中可能经历了大脑结构和功能的变化,这为他们持续易受个人伤害以及对后代未来伤害提供了环境。这些行为和感知变化表明,多种损伤的有害组合导致通过接触风险的情境、适应不良的常态化、情感创伤和危险的应对方式而持续易受反复伤害。
