Violence is today recognized as one of the major problemshumanity faces. The solution of this problem entails detailed evaluation of individual and social features and identification of their causes. Adolescence is a period during which violent behaviour occurs more frequently.individuals strive to be independent and find their identity. Violent behaviour coming to the forefront in such confusion may adversely affect the lives of individuals and may lead to irrecoverable situations. This study aimed to examine adolescents' attitudes toward violence with respect to such variables asgender, birth order, parents' level of education, andexposure to violence from parents. The research sample consisted of 436 ninth- and tenth- grade adolescents (220 girls and 216 boys),with ages ranging from 14 to 17, studying in an anatolian high school in Canik district of Samsun city in 2011-2012 training and education year. The research was carried out using the descriptive survey model. “Personal Information Form” and “the Attitudes toward Violence Scale” adapted to Turkish by Bulus, Duru and Balkis (2005) were used as data collection tools. In the analysis of data, "t-test" and "one-way analysis of variance" was used. The study discovered that violent tendencies of the boys were greater than those of the girls; violent tendencies of the firstborns were greater than those of the middleborns, lastborns or only child; violent tendencies of the adolescents with university-graduate mother were greater than those of the adolescents with elementary- or high-school-graduate mother; father’s level of education was not a predictor of attitudes towards violence; and the adolescents exposed to violence from their parents had greater violent tendencies. In accordance with the findings, it is suggested to extend educational activities for parents, to provide psychological support services rehabilitating adolescents, and to organize trainings to help adolescents utilize effective problem-solving methods
