The present study applied the social-ecological framework to explore factors associated with adolescents' experiences in bullying victimization in Taiwanese middle schools. Data include a random sample of 1,262 students, ages 13-15, from 43 middle schools in Taiwan's New Taipei City. Hierarchical generalized linear modeling was utilized to analyze the data, which included hierarchical and nested structures, such as individual and area level variables. Descriptive statistics and basic inferential analysis were conducted to test the hypotheses that individual (delinquency), family (parental monitoring), school (teacher support and teacher/staff punishment), community (community environment), and area levels (poverty rate) were associated with bullying victimization. Findings reveal that individual (Grade 7, conduct problems), school (teacher/staff punishment), community environment, and criminal activities had significant effects on bullying victimization in Taiwan. Implications for practice are discussed.
