Peer victimization refers to aggressive behavior directed at children by their peers, which can include both physical and non-physical forms. Smith (1991) characterizes it as unprovoked attacks causing psychological, social, or physical harm. Olweus (1994) emphasizes the repetitive nature of these negative actions and the presence of a power imbalance between the victim and the aggressor (Coloroso, 2002). Peer victimization can manifest physically through acts like fighting or assault, or non-physically through verbal abuse, emotional intimidation, and social exclusion (Hanish and Guerra, 2000; Mishna, 2003).
Research has indicated that victims of peer victimization are at risk for serious psychosocial issues, including anxiety, depression, and low self-esteem, with potential implications extending into adulthood (Olweus, 1978, 1993; Hawker and Boulton, 2000). Studies suggest that bullying is more common in younger children, although findings related to age and victimization experiences remain inconsistent (Nansel et al., 2001; Sourander et al., 2000). Gender differences in peer victimization are similarly complex; while some studies report higher rates of overt victimization among boys, others find that girls experience more relational victimization (Olweus, 1994; Crick and Grotpeter, 1995).
In Nigeria, there is a lack of reliable data on peer victimization among secondary school students, highlighting the need for further research in this field. This study aims to explore the prevalence of peer victimization in Nigeria to raise awareness among researchers about this important issue.
