It has become so worrisome that it has gained prominence in social discourse. The prevalence rate of conflicts between parent and adolescents in different parts of the world gives room for concern. Despite these researches, factors that predict the occurrence adequately investigated in this part of the world. This study therefore investigates the dispositional and environmental factor as predictor of parent-adolescent conflict among students in Ibadan. This study adopted a descriptive survey research design. Three hundred participants were selected from two secondary school in the metropolis using multi-stage sampling technique. The ages of the participants ranged between 11 and 20 years with a mean of 12.0 years (SD= 18.16). Three research questions were tested using multiple regression analysis and Pearson Product Moment Correlation. The findings revealed a significant positive relationships between emotional intelligence (r = 0.203**, p < 0.05); personality trait (r = 0.371**, P < 0.05). However aggression (r = -.313**, p < 0.05); parenting styles (r = -0.067, P< 0.05) was not significant. The three variables jointly accounted for 17.9% variance in the prediction of parent-adolescent conflict among the participants. The independent variables made positive relative contribution to parent-adolescent conflict in the following order: personality contributed most to the prediction of parent-adolescent conflict among secondary school adolescents in Ibadan (? = 0.314, t = 4.770, p < 0.05) followed by aggression (? = -.191, t = -3.320, p < 0.05). However, emotional intelligence is not a potent predictor of parent-adolescent conflict (? = 0.047, t = .726; p < 0.05) and parenting styles (? = -.096, t = -1.557; p < 0.05). Based on this finding, it is recommended that positive emotional intelligence and personality training should be organized to curb parent-adolescents conflict. Positive use of aggression should be encouraged among adolescents. Also, School Counsellor should intensify their efforts on the training of adolescent's moral uprightness so as to curb parent-adolescents conflict.
