The sample size in the life-course-persistent group was large enough to allow comparisons separately by gender, and the significance of these comparisons is indicated in each cell as well. The lack of significance for females in these comparisons needs to be interpreted with caution because of the much smaller number of females in the life-course-persistent group (11 females versus 31 males). Given the small sample size, it is particularly notable that divorce, poor health outcomes, and problem drinking are significantly more likely for life-course-persistent aggressive females than for the non-aggressive females.
