The first study dealt with children who were in the sixth, seventh, and eighth grades. Researchers gave a survey to the 163 participants, (72 males and 91 females). The survey listed 23 antisocial behaviours, and the young adolescents reported whether they had ever participated in each activity. Then each subject reported how frequently he or she had engaged in these activities over the past year. Because of the significant differences between how males and females answered 33% of the yes/no questions, researchers conducted factor analyses by gender.

This study found that there are many different reasons for adolescent antisocial behaviour. The researchers found that male adolescents tended to be more violent than females. Females who did exhibit violence did not direct their aggression at individuals as males did. Antisocial females tended to engage in other types of deviant behaviours, such as class cutting and drunkenness, more than their male counterparts.

The second study had similar results; however, it went further in explaining the causes of adolescent antisocial behaviours. Researchers conducted a longitudinal study where they studied 314 third, forth, and fifth graders. Later, when these children entered the ninth and tenth grade, the researchers returned to conduct further evaluations. Eighty-five percent of the original participants did not take part in the second half of the study; however, the researchers conducted analyses and discovered that these dropouts did not throw off their results.

In this article, I learned that there is clearly a gender difference in adolescent antisocial behaviour. The studies, however, bring up a couple of questions. First, how much does nature influence the gender difference, and what kind of a role does nurture play? In addition, I wonder why poor academic performance causes females to behave antisocially, and why academic performance does not effect their male counterparts in the same way.

If I were to conduct research based on the findings of these two studies, I would perform another longitudinal study. Because I have more questions about female antisocial behaviour, I can focus my study on just girls. I could take a sample of girls who are younger than those studied previously, evaluating them before they go to school. I can observe each girl's playtime behaviours and give the mothers surveys to evaluate their daughters' behaviours. In this longitudinal study, I would take measures more often than twice. I understand that morality in this type of study may suffer; therefore, I would take a sample of one thousand girls initially. I can evaluate these girls maybe every two years, using the methods I used with the preschoolers, as well as additional methods such as participant and teacher surveys. There
