Background and Purpose: Overt aggression has been of particular interest among relevant researchers because it is one of the major predictors of peer rejection, substance abuse, juvenile delinquency, criminal behavior, school maladjustments, and severe violent behaviors. Previous studies indicate that overt aggression develops in the early developmental stage and increases during adolescence. Based on these studies, it is important to prevent or reduces overt aggression during adolescence. In addition, it has been argued that there are gender differences in overt aggression trajectory during adolescence. For effective prevention or alleviation of overt aggression, it is required to examine what developmental changes in overt aggression are and whether overt aggression of boys and girls changes differently or not over time. The purpose of this study is to examine the trajectory of overt aggression and the gender differences in the trajectory among Korean adolescents. Methods: The data from Korean Youth Panel Survey (KYPS) of the fourth graders who were followed for five years (from 2004 to 2008) were analyzed using Hierarchical Linear Modeling (HLM). The final samples were composed of 2,844 fourth-grade students, and 2,448 adolescents participated in the fifth-year survey, resulting in a sample persistency rate of 86.1%. Among the 2,844 participants, 53.6% were male and 46.4% were female. The average age of the participants was 10.9 years. Overt aggression was measured using 6 items developed by KYPS and validated in Korean studies. Across the five years of data collection, internal consistency (Cronbach’s a) ranged from .757 to .807. Hierarchical analyses were conducted using HLM 6.02, and descriptive analyses were implemented using SPSS 20.0. Results: First, the results of an unconditional model indicate that overt aggression changed in a quadratic pattern. Specifically, overt aggression had a significant and positive slope mean coefficient (ß10 = .113, p < .001) and negative quadratic mean coefficient (ß20 = -.012, p < .001). It suggests that there was a significant average increase followed by a slight decrease in overt aggression. Second, the results of a conditional model indicate that there were gender differences in overt aggression trajectory. Specifically, gender 0=girls, 1=boys) had significant effects on the intercept (ß01 = .184, p < .001) and linear slope (ß11 = -.069, p < .001) of overt aggression. It means that boys’ initial level of over aggression was higher than girls, and overt aggression of girls increased more rapidly than boys for the five years. Conclusion: The results suggest that it is necessary to make deliberate efforts to alleviate overt aggression during adolescence and to consider gender differences in planning preventive and/or interventive programs for overt aggression. Based on the results that there were gender differences in the initial level and change rate of overt aggression, the prevention and/or intervention reflected with gender differences is expected to exert more effectiveness..
