A past experience of childhood trauma remains a major predictor of violent conduct amongst adolescents in low income and or developing countries as exemplified by Uganda, Kampala in particular. About the effects of emotional and physical abuse, neglect and witnessing domestic violence toward adolescent violent behaviour, this study employed a correlational research design. Two hundred and fourteen adolescents were interviewed through administration of assessment questionnaires measuring the level of trauma exposure and the presence of violent behaviours. Multiple correlation and regression analysis procedures were used in treating the data. The result showed that there was significant positive correlation between violent behavior and being emotionally or physically abused (0.486, p<.01), and witnessing domestic violence (0.447 p<.01). The degree of association explained by abuse was higher than that by neglect, and the results of the regression analysis further confirmed that emotional and physical abuse emerged as the strongest predictors (Coefficients = 0.316, p<.01), followed by, witnessing domestic violence (Coefficients = 0.185, p<.01), while neglect did not significantly predict adulthood dating violence (Coefficients = 0.059, p Overall, the seven independent variables explained 24.7% of the violent behaviour, (R² = .258; F (7, 92) = 23.093, p <. 01); this shows that there are other variables that may influence the violent behaviour. From these results it is pointed out that child maltreatment is significantly associated with violence in youths and therefore calls for the incorporation of trauma-sensitive approaches. Some of the possible recommendations, include: Schools, policies, and mental health workers should use programs addressing the impact of abuse and domestic violence; child protection laws should be reinforced, and there should be increased access to mental health for adolescents in a bid to curb violence among youngsters and enhance better development.
