Children who showed a higher degree of social competence in nursery school were more likely to have succeeded in all five categories. "For every one-point decrease in the child's score, he or she had a 67 percent higher chance of having been arrested and an 82 percent higher chance of being in or on a waiting list for public housing at age 25."
The study examined and took into account the effects of poverty, race, having teenage parents, family stress, neighborhood crime, and aggression and reading level of the child while in nursery school.
Now of course this study doesn't mean or prove that just because a child does not interact high on a social scale with others they are destined to a life a crime. However, if you combine this research with other research existing, it stresses the importance of helping children develop these social skills early on to increase their chance of success in school, work and life.
This is why pre-school is so important for all children, not just those lucky enough to have parents who figure out a way to pay for it.
