This study investigates bullying incidence among post primary adolescents to ascertain if a correlation exists between bullying, self-esteem, health complaints and mood/affect. It is expected that bully/victims will show lower signs of self-esteem, a lower affect and a higher level of physical complaints than those who are not involved in bullying. The report predicted that there would be a statistically significant relationship between bullying, self-esteem, health complaints and mood. The physical complaints scale, items 4 and 24, from the revised Olweus Bully/Victim questionnaire, Rosenberg Self-Esteem Scale and the Positive and Negative Affect Scale were distributed to 113 mixed sex post primary school students. Analysis was conducted through examining Pearson Correlations and ANOVA procedures. The data collected for this study could help to design an anti-bullying programme for the schools involved.
