1.1 Introduction
Domestic violence is defined as a pattern of behavior in any relationship that is used to gain or maintain power and control over an intimate partner or family member and it includes physical, emotional, psychological, sexual, and economic abuse (World Health Organization, 2021). In many households, children are not only passive observers but also active victims of the emotional consequences of such violence, which places them at significant risk of mental and behavioral health challenges.
The family environment is expected to serve as a primary source of safety, emotional support, and social development for children. However, when domestic violence occurs within the home, this foundation of stability is disrupted, exposing children to fear, insecurity, and chronic stress. According to Evans, Davies, and DiLillo (2008), children who are exposed to domestic violence often experience long-term psychological difficulties such as anxiety, depression, and post-traumatic stress symptoms, which interfere with normal emotional and cognitive development.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Domestic violence is a widespread social and public health issue that continues to affect millions of families globally and its impact extends beyond the immediate victims to children who grow up in such environments. According to the World Health Organization (2021), domestic violence is a pattern of behavior in intimate or family relationships that is used to gain or maintain power and control over another person and it includes physical, emotional, psychological, sexual, and economic abuse. Children who are exposed to such environments often experience emotional instability and developmental challenges that may persist throughout their lives.
Evans, Davies, and DiLillo (2008) reported that children who are exposed to domestic violence are at higher risk of developing psychological problems such as anxiety, depression, and post-traumatic stress symptoms. They further stated that exposure to violence in the home disrupts normal emotional development and affects how children perceive safety and trust in relationships. In many cases, these children grow up in environments characterized by fear, unpredictability, and emotional neglect, which significantly shape their mental health outcomes.
Felitti et al. (1998) asserted that adverse childhood experiences, including exposure to domestic violence, are strongly linked to long-term health consequences such as mental illness, substance abuse, and chronic diseases in adulthood. They emphasized that early exposure to traumatic events interferes with brain development and stress regulation systems, making affected children more vulnerable to emotional and behavioral disorders later in life.
UNICEF (2017) stated that children living in violent households often struggle with emotional regulation and social interaction, which affects their performance in school and relationships with peers. The organization further affirmed that such children are more likely to exhibit aggressive behavior, withdrawal from social activities, and low self-esteem. These behavioral patterns are often misunderstood, leading to labeling and further marginalization of affected children within school and community settings.
According to Kitzmann et al. (2003), exposure to interparental violence is associated with both internalizing and externalizing behavioral problems in children. They reported that internalizing problems include depression, anxiety, and fearfulness, while externalizing problems include aggression and disruptive behavior. This dual impact shows that domestic violence affects children in complex ways that influence both their emotional state and outward behavior.
WHO (2021) further contended that domestic violence creates a cycle of trauma within families, where children who grow up in violent homes are more likely to either become victims or perpetrators of violence in adulthood. This intergenerational transmission of violence suggests that the effects of domestic violence are not limited to the present but extend into future generations, thereby perpetuating a cycle of psychological and social dysfunction. Moreover, Hughes et al. (2017) reported that prolonged exposure to domestic violence affects brain development, particularly in areas responsible for emotional regulation, memory, and decision-making. They emphasized that toxic stress caused by chronic exposure to violence disrupts normal neurological development, leading to long-term cognitive and emotional difficulties.
In many developing countries, including Nigeria, domestic violence remains underreported due to cultural norms, stigma, and fear of retaliation. According to the National Population Commission (NPC, 2019), a significant number of women and children experience violence in their homes but do not report it due to social pressures and lack of institutional support. Furthermore, mental health services for children in many regions remain inadequate, making it difficult to identify and treat psychological disorders resulting from exposure to domestic violence. Early intervention is crucial, yet many children suffer in silence without access to professional support or counseling services. This study is set against the backdrop of the growing need to understand how domestic violence affects child mental health, particularly in environments where awareness, prevention, and intervention mechanisms remain inadequate.
1.3 Statement of Problems
In many households, children are not only indirect witnesses but are also direct victims of the emotional consequences that arise from such violence, which places them at significant risk of mental health disturbances. Research has shown that children who witness domestic violence are more likely to experience low self-esteem and social withdrawal, and they may also exhibit violent or antisocial behavior as they grow older (UNICEF, 2017). These outcomes create a cycle of violence that may persist across generations if not properly addressed. In many cases, mental health issues among affected children remain unrecognized or untreated due to stigma, lack of awareness, and limited access to mental health services, especially in developing regions.
Furthermore, some children exposed to domestic violence may display resilience due to protective factors such as supportive caregivers, stable school environments, or access to counseling services. However, such protective factors are not always present, particularly in low-income households where stressors are already high and access to professional mental health support is limited. It is against this backdrop that this study seeks to understand the effects of domestic violence on child mental health.
1.4 Aim and Objectives of Study
The aim of this study is to assess the effects of domestic violence on child mental health in Lagos State, Nigeria.

1.7 Significance of Study
It is believed that at the completion of the study, the findings will support mental health professionals in identifying early psychological symptoms in children exposed to domestic violence. The research will also assist policymakers in strengthening child protection and mental health intervention programs.
Furthermore, the findings will help school administrators in developing early detection and referral systems for affected students.
Lastly, the outcome of this research will contribute to academic literature on domestic violence and child psychological development.
1.8 Scope and Limitations of the Study
This study focuses on the effects of domestic violence on child mental health in Lagos State, Nigeria, with specific attention to selected secondary schools and child welfare institutions within Lagos Mainland Local Government Area.
The study was limited to Lagos State due to accessibility and time constraints, which restricted wider generalization across other Nigerian states.
