Finally, the late-onset adult aggression group displayed a number of more negative outcomes than the low-aggressive group though not nearly as many as those displayed by the life-course-persistent aggressives. These are participants who were below average on aggressiveness through the end of their teen years, and then suddenly started behaving aggressively in young adulthood. Despite the late onset of this aggression, they show significantly higher problem drinking, depression, and spouse aggression, and significantly poorer health than their peers who remained below average on aggression into their 40s.
