Abstract
Child maltreatment, which includes abuse, neglect, and witnessing violence, has severe consequences on the development and psychological well-being of the young child. This literature review aims to systematically integrate the knowledge from the identified articles, which examines the effects of early trauma on individuals’ cognitive, emotional, and social development, as well as their overall psychosocial outcomes. The historical and emerging perspective on trauma and treatment in early childhood can be viewed from the paper by Buss, Warren, and Horton (2015); it necessitates early childhood intervention. Two other pieces of research evidence, Kuzminskaite et al. (2021) and Strathearn et al. (2020) provide valuable systematic evidence of the psychological, biological, and health correlates of childhood trauma.
Studying the NESDA dataset, Kuzminskaite et al. (2021) examine the psychological and biological pathways by which childhood trauma predicts adult depressive and anxiety disorders. They highlighted the importance of inflammation and HPA axis function in these outcomes. In their study, Child Abuse and Neglect: Long-term Consequences in Adulthood for Cognitive, psychological, and Health Outcomes, by Strathearn et al. (2020), the researchers employed the Mater–-University of Queensland Study of Pregnancy. They demonstrate dose-response relations, which support the hypothesis that higher levels of trauma are associated with worse cognitive performance, more psychiatric symptoms, and health problems. Altogether, these findings indicate a strong positive relationship between childhood trauma and subsequent psychiatric disorders, behavioral and emotional disturbances, and interpersonal relationship dysfunction.
Introduction
This paper focuses on child abuse and neglect, well-known problems that have long-lasting consequences on a person’s physical, psychological, and social growth. Developmentalists stress that trauma is most dangerous during early childhood and is a time when brain organization and the development of attachment relationships occur (Buss et al., 2015). Maltreatment might have adverse effects on children’s cognitive, emotional, and social development and was associated with specific psychosocial adjustment. This literature review aims to investigate the effects of early childhood trauma on brain development and later psychosocial outcomes, focusing on two primary research questions: This literature review aims to investigate the effects of early childhood trauma on brain development and later psychosocial outcomes, focusing on two primary research questions:
- What are the consequences of early childhood trauma on brain growth by regions relevant to learning, feeling, and interacting?
- The following are the probable adverse psychosocial factors connected with early childhood trauma: Mental illnesses, behavior issues, and interpersonal relationship challenges.
Focused Empirical Study Review
The historical and emerging literature on trauma and treatment in early childhood is systematically discussed by Buss, Warren & Horton (2015). They point out the effects of early stress on the subsequent development of the child and underscore the importance of trauma for socio-developmental results. The authors describe the various therapeutic modalities and emphasize the timely identification of the child and individualized care for traumatized children. In their review, they mention areas of the brain that are susceptible to changes by trauma, such as areas related to emotion, memory, and stress. The paper also looks at other factors, such as genetics and the environment, that regulate the effects of trauma.
Kuzminskaite et al. (2021) employed a cross-sectional design in the NESDA sample to analyze the associations between CTS and AD and depression and anxiety disorders. Their research is a conjunction of both psychological and biological aspects to study how childhood trauma affects mental health in adulthood. The study used a systematic review approach aimed at obtaining a large sample of assessments regarding childhood trauma, psychopathological ratings, and biological measures of inflammation and the HPA axis. Some of the main results obtained show a significant connection between childhood victimization and the presence of anxiety disorders, emotional dysregulation, and attachment disorders. This study also reports variable biological alterations such as inflammation and HPA axis abnormalities in subjects with a history of childhood trauma and their consequent psychopathology.
Strathearn et al. (2020) designed and executed a cohort investigation within the framework of the Mater–University of Queensland Study of Pregnancy to determine the persistence of child abuse and neglect in cognition, psychopathology, and health. The research involved people from birth to 30 years, with childhood abuse determined via maternal or the subject’s account. Cognitive traits were assessed with tests, while psychological traits, including depression, were assessed with self-report and biological measures. The research showed that people who received one or multiple forms of childhood abuse were likely to be characterized by lower cognitive functioning, higher rates of depression and anxiety, and physical health problems. The dose-response relationship emphasized that increased trauma severity was associated with compromised cognitive status, psychological well-being, and physical wellbeing.
Discussion
The present research findings illustrate the detrimental effects of ECPT on child brain development and subsequent psychosocial adjustment. Buss et al. (2015) note that the treatment of traumatized children must include early intervention and therapeutic goals and methods. Kuzminskaite et al., 2021 further substantiate childhood trauma as an inherent risk factor for adulthood mental health disorders and focus on aspects like inflammation and HPA axis dysregulation. Building on this research, Strathearn et al. (2020) further explain the long-term outcomes of childhood abuse and neglect on children’s cognitive, psychological, and health domains.
In combination, these studies consider essential elements of the research questions, proposing how early trauma impacts brain maturation and results in sustained psychosocial difficulties. However, several limitations and questions are left unresolved. For example, future research might explore the moderators of the dose-response where trauma severity is concerned and psychosocial outcomes. Further, more has to be done about understanding how different types of therapeutic practices can help to reduce the impact of early trauma.
Overall, the sequelae of early childhood trauma involve changes in the developing brain and later psychological wellbeing. It also highlights the importance of timely detection and intervention to enable children with trauma to be provided with care as early as possible to close the gap and promote their healthy development.
