The study examined psychosocial factors predisposing aggressive behaviour among secondary schools students in Edo State, Nigeria. Three research questions and two hypotheses were answered and tested in the study. The study adopted the descriptive survey research design. The population of this study covered all  sixteen thousand three hundred and seventy two (16,372) Senior Secondary School one (SSS 1) students in Edo State.  A sample of one hundred and sixty three (163) representing 1 percent of secondary school students was drawn using the simple sampling technique. The instrument used was titled: Psycho-social Factors Predisposing Aggressive Behaviour Questionnaire (PFPBQ). The mean and standard deviation was used to analyse the research question 1. Hypotheses were tested with the t-test for two independent sample means respectively. The test of hypotheses was carried out at 0.05 level of significance. The result from the analyses showed that the psychosocial factors (parental discipline, parental role modelling and parental substance abuse) were positively perceived as predisposers of aggressive behaviours among students in secondary schools in Edo State. It was recommended that parents should be affectionate, accepting and helpful to their children; schools should have regular parent awareness programs based on their experiences and research.
