Project – School Bullying and Psychological Well-Being among Secondary School Students: A Socio-Psychological Study of Selected Secondary Schools in Lagos State

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Education is not limited to the transmission of academic knowledge and intellectual skills. It also involves the development of learners’ emotional, social, psychological and moral capacities. For students to learn effectively, the school environment must provide a sense of safety, belonging, acceptance and support. A school environment characterised by intimidation, aggression, humiliation or exclusion can undermine these conditions and negatively affect students’ development. Consequently, school bullying has become an important educational and socio-psychological concern because of its potential implications for students’ emotional well-being, social relationships, academic engagement and overall development.

Bullying is generally understood as repeated aggressive behaviour involving a power imbalance between the perpetrator and the victim. It can take physical, verbal, relational or psychological forms and may also occur through digital technologies as cyberbullying. The World Health Organization (WHO) identifies bullying as a form of violence against children involving deliberate and unwanted aggressive behaviour, repeated harm and an imbalance of power. It may be physical, psychological or social and can occur in schools as well as online environments. Bullying therefore differs from an ordinary disagreement between students because it involves patterns of harmful behaviour and an unequal capacity to defend oneself.

School bullying can occur in different forms. Physical bullying includes hitting, kicking, pushing, fighting or damaging another student’s belongings. Verbal bullying involves insults, threats, ridicule, name-calling and humiliating comments. Relational or social bullying involves deliberately excluding a student from a peer group, spreading rumours or damaging the person’s social reputation. Cyberbullying occurs through mobile phones, social networking platforms, messaging applications and other digital technologies. These different forms may produce different experiences, but all have the potential to undermine students’ psychological well-being.

Adolescence is an especially important developmental period in which bullying can have serious consequences. Secondary school students are experiencing significant physical, emotional and social changes while simultaneously developing their identities, self-esteem, interpersonal relationships and sense of belonging. Peer acceptance becomes particularly important during this period. Consequently, repeated rejection, humiliation or intimidation by peers may affect how students perceive themselves and their relationships with others.

Psychological well-being refers broadly to an individual’s positive psychological functioning and capacity to experience meaning, self-acceptance, positive relationships, personal growth, autonomy and effective management of the environment. Ryff (1989) conceptualised psychological well-being through dimensions including self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life and personal growth. From this perspective, psychological well-being is broader than the absence of mental illness; it concerns whether individuals are functioning positively and experiencing a meaningful and satisfying psychological life.

The psychological well-being of adolescents is particularly important because experiences during adolescence can influence later development. The WHO (2025) reports that approximately one in seven adolescents aged 10–19 experiences a mental health condition globally and identifies exposure to violence and bullying among recognised risks to adolescent mental health. The organisation further emphasises that supportive environments in families, schools and communities are important protective factors for adolescent mental health.

The school environment is consequently an important social context for adolescent psychological development. Students spend a substantial proportion of their formative years in schools, where they interact with teachers and peers and develop social competencies. A supportive school environment can strengthen students’ sense of belonging and emotional security, whereas hostile peer relationships may produce fear, isolation and emotional distress.

Bullying can interfere with this supportive function of the school. A student who repeatedly experiences intimidation may begin to associate school with fear rather than learning and personal development. Victims may avoid particular locations within the school, withdraw from classmates, become reluctant to participate in classroom activities or experience anxiety about attending school. Such experiences may consequently affect both psychological well-being and educational outcomes.

International evidence has established that school violence and bullying constitute significant threats to children’s educational and psychological development. UNESCO’s work on school violence and bullying has highlighted the widespread nature of the problem and the need for education systems to create safe, inclusive and supportive learning environments. WHO similarly identifies bullying as part of youth violence and notes its association with emotional distress, loneliness, anxiety, depression and other adverse outcomes.

The effects of bullying may extend beyond immediate emotional discomfort. Repeated exposure to humiliation, threats or social rejection may affect students’ self-esteem and confidence. Students who perceive themselves as powerless may develop negative beliefs about their abilities and social worth. Where bullying persists without appropriate intervention, victims may also become increasingly isolated from peers and school activities.

The relationship between bullying and psychological well-being is therefore important from a socio-psychological perspective. Bullying is not simply an individual behavioural problem; it occurs within social relationships and group structures. Peer groups can determine who is accepted, rejected, respected or ridiculed. Social status, friendship networks and group norms can therefore influence both the occurrence of bullying and the way victims respond to it.

The social environment can also influence whether students report bullying. Some students may fear retaliation from bullies, rejection by peers or being labelled as weak. Others may believe that teachers or school authorities will not take their complaints seriously. UNICEF’s national evidence on violence against children in Nigeria found that many children do not report violence because of fear, shame, stigma and inadequate knowledge about where to seek help. Although the UNICEF evidence covers violence against children more broadly than school bullying alone, it illustrates the importance of under-reporting when examining violence affecting Nigerian children.

Nigeria has a substantial population of children and adolescents, making the protection and psychological well-being of school-age children a significant national development issue. The 2024 Nigeria Situation Analysis of Children and Adolescents reports that children and adolescents aged 0–17 constitute almost half of Nigeria’s population and identifies violence affecting children as one of the country’s continuing challenges. This demographic reality makes the creation of safe school environments essential for Nigeria’s educational and human-capital development.

Evidence from Nigeria indicates that violence against children can occur in places where children are expected to be safe, including schools and routes to and from school. The national Violence Against Children Survey reported that six in ten Nigerian children experienced at least one form of physical, sexual or emotional violence before age 18, with many experiencing violence repeatedly. While not all such experiences constitute bullying, the findings demonstrate the wider environment of violence and vulnerability within which Nigerian children develop.

The problem has also received increasing attention from Nigerian education authorities. The Federal Ministry of Education’s Managing Violence in Schools: Handbook for Schools and Learning Centres identifies school-based violence as a threat to learners’ well-being, academic success, emotional development and future opportunities. The handbook provides practical guidance for teachers, school administrators and other stakeholders on preventing and responding to violence in educational settings.

The Nigerian school environment is influenced by broader social factors that may affect peer relationships. Family circumstances, socioeconomic inequalities, parenting practices, community violence, peer-group norms, school discipline and exposure to aggressive behaviour can all contribute to the development or reinforcement of bullying behaviours. The WHO identifies poor parental supervision, harsh or inconsistent discipline, low attachment, association with delinquent peers, poverty and exposure to violence as factors associated with youth violence.

Bullying may also be reinforced by peer observation. In some situations, students who witness bullying may laugh, encourage the aggressor, remain silent or intervene on behalf of the victim. These responses can influence whether bullying continues. From a social learning perspective, behaviour that appears to produce social status or peer approval may be repeated, while behaviour that is discouraged by peers and authorities may become less attractive.

Teachers and school administrators therefore have an important role in preventing bullying. Effective school management involves more than academic supervision; it includes creating rules and procedures that protect students from violence and intimidation. Schools need mechanisms through which students can safely report bullying and receive appropriate support. Teachers also need to recognise less visible forms of bullying, such as social exclusion, humiliation and online harassment.

The relationship between bullying and academic life is another important consideration. Students experiencing persistent bullying may have difficulty concentrating in class, become reluctant to attend school or lose interest in academic activities. WHO notes that violence affecting young people is associated with school dropout and negative effects on cognitive development and educational opportunities. Therefore, bullying has implications not only for students’ psychological well-being but also for the broader educational objectives of schools.

Psychological well-being can also influence how students respond to stressful social experiences. Students with strong social support, positive self-esteem and effective coping skills may be better able to manage difficult peer relationships. Conversely, students who lack supportive relationships may be more vulnerable to the psychological consequences of bullying. This makes peer support, teacher support and family support important components of school-based approaches to bullying prevention.

The increasing use of digital technology has introduced another dimension to the problem. Cyberbullying can extend harmful peer interactions beyond the physical boundaries of the school. A student who is bullied at school may continue to encounter insults, embarrassing images, threats or exclusion through social media and messaging platforms after school hours. This can make psychological recovery more difficult because the student may feel that there is no safe environment away from the aggressor.

At the same time, technology can be used as a tool for prevention and support. Schools can educate students about responsible digital citizenship, online safety and appropriate ways of reporting cyberbullying. Teachers and parents can also monitor patterns of online abuse while respecting appropriate privacy and safeguarding principles.

An important feature of bullying research is the recognition that students may occupy different roles. Some are direct victims, some are perpetrators, while others may be both victims and perpetrators. There are also bystanders who observe bullying without directly participating. Each role may have different psychological and social implications. Consequently, school interventions should not focus only on punishing individual bullies but should address the broader peer culture that allows harmful behaviour to occur.

The Lagos State context is particularly relevant to this study. Lagos is Nigeria’s most populous state and has a large and diverse population of secondary school students. Schools in the state operate within highly varied socioeconomic and cultural environments. Differences in school type, neighbourhood characteristics, family backgrounds and access to educational resources may influence students’ experiences of peer relationships and school safety.

Recent Nigerian research provides particularly relevant evidence from Lagos State. A 2026 study by Azuka-Obieke examined bullying and psychological well-being among senior secondary school students in Eti-Osa Local Government Area of Lagos State and reported a significant relationship between bullying and students’ psychological well-being, including a significant relationship involving verbal bullying. This recent evidence strengthens the importance of investigating the subject within Lagos State while also demonstrating the need for continued research across different school contexts.

However, findings from one local government area cannot automatically be generalised to all secondary schools in Lagos State. Schools differ in their student populations, management structures, disciplinary systems, teacher-student relationships and socioeconomic environments. A study involving selected secondary schools can therefore provide additional evidence about how bullying relates to students’ psychological well-being within the broader Lagos educational context.

The socio-psychological approach adopted in this study is important because it recognises that students’ psychological experiences are shaped by their social environments. Bullying occurs through relationships between students and is influenced by peer groups, school culture and broader social norms. At the same time, the effects of bullying are experienced psychologically through changes in self-esteem, emotional stability, social confidence, sense of belonging and general well-being.

The importance of addressing the problem extends beyond individual students. A school where bullying is widespread may develop an atmosphere of fear and insecurity that affects students who are not directly victimised. Students who witness bullying may also experience anxiety or feel unsafe. Teachers may spend more time dealing with behavioural conflicts, while parents may become concerned about their children’s safety.

Preventing bullying is therefore consistent with the broader objective of creating safe and supportive learning environments. WHO recommends school-based violence-prevention approaches, including whole-school strategies, life-skills education and programmes designed to strengthen social and emotional skills. Such approaches are relevant because bullying is a social problem requiring coordinated responses rather than isolated disciplinary measures.

Against this background, this study investigates the relationship between school bullying and psychological well-being among secondary school students in selected secondary schools in Lagos State. The study focuses on the forms and extent of bullying experienced by students and examines how such experiences relate to their psychological well-being. It is expected that the findings will provide useful evidence for teachers, school administrators, parents, counsellors, policymakers and other stakeholders concerned with creating safe and psychologically supportive school environments.

1.2 Statement of the Problem

School bullying remains a serious concern because schools are expected to provide environments where students can learn, develop social relationships and achieve their potential in safety. However, repeated physical, verbal, relational and psychological aggression among students can undermine this expectation. When students are mocked, threatened, intimidated, excluded or physically attacked by peers, the school environment may become a source of fear rather than a place of learning and personal development.

The problem is particularly important because adolescence is a sensitive period of psychological and social development. Secondary school students are developing their self-concepts, identities, interpersonal relationships and emotional regulation skills. Persistent bullying during this period may interfere with positive development by exposing students to repeated humiliation, rejection, fear and social isolation.

One major concern is the possible effect of bullying on students’ psychological well-being. Students who experience repeated bullying may develop reduced self-esteem, anxiety, loneliness, emotional distress and negative perceptions of themselves and others. WHO recognises bullying and other forms of violence as risks to adolescent mental health and notes that exposure to violence can contribute to anxiety, depression and other psychological difficulties.

The Nigerian context makes the problem particularly significant. National evidence shows that violence against children is widespread and that children may experience violence in places where they should be protected, including schools. The Federal Ministry of Education has consequently recognised school-based violence as a threat to students’ well-being, emotional development and academic success.

Despite the seriousness of the problem, bullying may remain hidden within schools. Some students do not report bullying because they fear retaliation, embarrassment or rejection. Others may consider bullying a normal part of growing up or may believe that reporting it will not result in meaningful intervention. This under-reporting can make the actual extent of the problem difficult for school administrators and parents to determine.

Another problem is that bullying is not always physical or easily observable. Physical attacks may be noticed by teachers, but verbal insults, social exclusion, spreading rumours, humiliation and cyberbullying can occur without immediate detection. Consequently, a school may appear orderly while some students are experiencing serious psychological distress caused by peer victimisation.

The increasing use of digital communication has further complicated the problem. Cyberbullying can occur through social networking sites and messaging platforms and may continue outside school hours. This means that students may experience bullying across both physical and digital environments, increasing the potential for continuous exposure to harmful peer interactions.

There is also concern about the possible effects of bullying on students’ educational engagement. A student who feels unsafe may avoid particular classes, locations or social activities within the school. Persistent anxiety or fear may reduce concentration and motivation. WHO identifies violence among young people as being associated with school dropout and negative effects on educational opportunities.

The problem is not limited to victims alone. Students who bully others may also experience behavioural and social difficulties, while bystanders may become desensitised to aggression or fearful of becoming victims themselves. Consequently, bullying can negatively affect the broader school climate.

Evidence from Lagos State further demonstrates the need for investigation. Recent research conducted among senior secondary school students in Eti-Osa Local Government Area reported a significant relationship between bullying and psychological well-being. While this finding is important, there remains a need for further investigation among students in other selected secondary schools and school environments in Lagos State.

The existence of evidence from Eti-Osa also raises an important research question concerning whether similar relationships can be observed in other school contexts. Differences in school management, student composition, socioeconomic background, teacher supervision and peer culture may influence both the prevalence of bullying and its psychological consequences.

The central problem addressed by this study is therefore the insufficient understanding of the extent to which school bullying affects the psychological well-being of secondary school students in selected schools in Lagos State. Although bullying is recognised as an important child-protection and educational issue, the experiences of students within particular school environments require continued empirical investigation.

This study consequently seeks to determine whether school bullying is significantly related to psychological well-being among secondary school students in selected secondary schools in Lagos State. Establishing this relationship can provide evidence for the development of appropriate counselling, school-based prevention and student-support strategies.

1.3 Aim of the Study

The main aim of this study is to examine the influence of school bullying on the psychological well-being of secondary school students in selected secondary schools in Lagos State.

1.4 Objectives of the Study

The specific objectives are to:

1. examine the prevalence and forms of bullying experienced by secondary school students in selected schools in Lagos State;
2. assess the level of psychological well-being among secondary school students in the selected schools;
3. examine the relationship between physical bullying and students’ psychological well-being;
4. determine the relationship between verbal bullying and students’ psychological well-being; and
5. examine the relationship between relational/social bullying and students’ psychological well-being.

1.5 Research Questions

The study will be guided by the following research questions:

1. What forms of bullying are experienced by secondary school students in selected schools in Lagos State?
2. What is the level of psychological well-being among secondary school students in the selected schools?
3. What relationship exists between physical bullying and students’ psychological well-being?
4. What relationship exists between verbal bullying and students’ psychological well-being?
5. What relationship exists between relational/social bullying and students’ psychological well-being?

1.6 Research Hypothesis

The following null hypothesis will be tested at the 0.05 level of significance:

H₀: There is no significant relationship between school bullying and psychological well-being among secondary school students in selected secondary schools in Lagos State.

1.7 Significance of the Study

The study will be significant to secondary school administrators because it will provide empirical evidence about the relationship between bullying and students’ psychological well-being. The findings may assist school administrators in strengthening anti-bullying policies, reporting procedures, supervision and student-support systems.

Teachers will also benefit from the study. Understanding the psychological implications of bullying may enable teachers to recognise warning signs and respond appropriately to students experiencing peer victimisation. Teachers can also contribute to prevention by promoting respectful peer relationships and discouraging aggressive behaviour.

School counsellors will be important beneficiaries of the study. The findings may help counsellors design interventions aimed at strengthening students’ self-esteem, coping skills, interpersonal relationships and emotional resilience. Counselling programmes can also provide safe channels through which students can disclose bullying experiences.

Parents and guardians may benefit from the findings because they may become more aware of the possible psychological effects of bullying. The study may encourage parents to pay attention to changes in their children’s behaviour, school attendance, social relationships and emotional state.

The study will also be useful to students. By highlighting the consequences of bullying, it may encourage students to reject aggressive behaviour, support victims and report serious incidents to appropriate adults. Students may also become more aware of the importance of creating respectful and inclusive peer environments.

Educational policymakers in Lagos State may use the findings to strengthen policies and programmes designed to prevent school-based violence and promote student well-being. This is consistent with the broader emphasis on safe and supportive learning environments in Nigeria’s education system.

Child-protection agencies and non-governmental organisations may also find the study useful in designing school-based interventions. Evidence concerning the relationship between bullying and psychological well-being can help organisations target their prevention and support programmes more effectively.

Finally, the study will contribute to the literature in educational psychology, sociology of education and socio-psychology of education. It will provide a basis for further studies on bullying, peer relationships, school climate, psychological well-being and academic outcomes among Nigerian students.

1.8 Scope of the Study

The study focuses on school bullying and psychological well-being among secondary school students in selected secondary schools in Lagos State.

The study will examine major forms of bullying, particularly physical, verbal and relational/social bullying. Where relevant, cyberbullying will also be considered as part of the contemporary school bullying environment.

The dependent variable is students’ psychological well-being, while school bullying constitutes the major independent variable. Psychological well-being will be considered in relation to dimensions such as self-acceptance, positive relationships, emotional functioning, sense of purpose and general psychological adjustment.

Geographically, the study will be restricted to selected secondary schools in Lagos State. The study will therefore not claim that the findings represent every secondary school student in Nigeria.
