The purpose of this study is to examine the relation among adolescents' perception of parental overprotection, goal-seeking orientation, self-handicapping and academic procrastination. Questionnaires were administered to 1200 male and female high school students in Gyeonggi Province. A total of 942 questionnaires were statistically analyzed through mean, standard deviation, frequency analysis, one-way analysis of variance, Pearson‘s correlation analysis, and multiple regression analysis. The major results of the study are as follows: First, adolescents’ academic procrastination differed by school grades. Second, for the high-performing group, self-handicapping, goal-seeking orientation and parental overprotection were significant predictors of their academic procrastination. For the mid-level performing group, self-handicapping and goal-seeking orientation were significant predictors of their academic procrastination. For the low-performing group, self-handicapping was the only predictor of their academic procrastination. Third, for the high-performing group, self-handicapping meditated the relation between parental overprotection and academic procrastination. Those results provide useful information regarding proactive support or intervention for adolescents’ academic procrastination.
