Objective: School bullying in Malaysia is on the rise. While efforts are put together to combat the problem, the psychiatric aspect has been neglected. This is a cross-sectional study aimed to determine the association between the symptoms of ADHD and bully/victim problems among Malaysian sixth-graders attending primary schools in Kuala Lumpur. Methods: A total of 410 sixth-graders from seven randomly selected schools were assessed with regards to bully/victim problems and ADHD symptoms using self-reported questionnaires. Malaysian Bullying Questionnaire was used to rate bully/victim problems while ADHD symptoms were assessed using Conners-Wells’ Adolescent Self-report Scale (CASS). Teachers and parents also assessed students’ ADHD symptoms using Conner’s Teachers Rating Scale (CTRS) and Conner’s Parents Rating Scale (CPRS), respectively. Results: Self-reported questionnaires showed that 61.2% of the children were involved in bully/victim problems. The ADHD symptoms were found significant in relation to bully/victim problems as tested by multiple logistic regression. Only students and parents reported significant ADHD symptoms among the bully/victim groups. The ADHD symptoms reported by students were significant among bullies(OR=0.59,CI=0.42-0.83, p<0.01) and bully-victims(OR=0.55 CI=0.37-0.81,p<0.00). Parents reported significant ADHD symptoms only in victims(OR=1.260,CI=1.02-1.56,p=0.03). Conclusion: The ADHD symptoms were significantly present among bullies, victims and bully-victims. These findings open a new perspective of managing bully/victim problems since effective treatment is available for ADHD.
