The aim of this research is to investigate interparental conflict, peer and media effects and its direct relationship with the violence behaviour of adolescents and the mediator role of attitudes towards violence. 2120 students, 964 girls and 1156 boys chosen from 7th and 8th grades of one private and eleven public elementary schools in Adana have made up the sampling group of this study. In this research, Attitudes towards Violence Scale, Aggression Questionnaire, Perceived Multidimensional Violence Sources Inventory and Children's Perception of Interparental Conflict Scale have been administered to the students. Research data have been tested by using Structural Equation Modeling. The results reveal that variables except interparental conflict have positive effect on this model. It has been found that attitudes towards violence have partial mediator role in the relationship between media-peer effects and physical violence while they have entire mediator role in the relationship between media-peer effects and verbal violence. The research findings have been discussed within social cognitive model context.
