Negative coefficients indicate that boys reported higher scores; positive coefficients indicate that girls reported higher scores. Coefficient for gender at 14.4 is the coefficient of gender at the mean of age. Interaction terms for fear perpetration, injury perpetration, sexual victimization, and injury victimization were significant at P < .05. Interaction terms for physical perpetration, physical victimization, and fear victimization were significant at P < .10.

Statistically significant.
