This study investigated the experience of physical violence among adolescents and the domestic variables explaining sibling violence. Data were collected from 501 adolescents in 2007 and analyzed using SPSS 16.0. The statistics used for analysis were the T-Test, two-way ANOVA, and regression. Findings indicated that 45% of the sample population had experienced sibling violence and the most common acts were "hit with hand or objects". The violence of parents toward their children, gender, and the frequency of conflict between siblings were associated with sibling violence. From these results, the study proposed that education about sibling violence should be included in social work programs.
