The goal of this study was to describe the strength-based bullying prevention program, "Strengths in Motion," and to evaluate the program utilizing a mixed-method design. Participants included students in Grades 4 to 8 from an intervention (n = 50) and a comparison (n = 53) school in Northern Ontario. Measures of bullying, strengths, and classroom climate were completed at three time points: One month prior to the start of the program (baseline), and at 3 and 8 months after the program had started. Quantitative analyses revealed that there was a significant decrease in students' bullying victimization over time, an increase in classroom climate, and students' personal awareness of their strengths. Semistructured interviews conducted 20 months after the start of the program with various stakeholders, including parents and school staff, complemented these findings and provided additional information on the efficacy of the program and the strength-based approach. Study findings are discussed in terms of the implications for future research. (Contains 1 table and 2 figures.)
