The main objective of the study was to explore the main predictors that influence academic stress among fourth-grade elementary school students using data from the Panel Study on Korean Children via a least absolute shrinkage and selection operator (LASSO) regularized penalty regression model. The study examined 280 explanatory variables using the LASSO model. After preprocessing the data, it finally selected 21 variables. Out of them, the study found that children’s persistence, peer attachment, bullying, parental achievement pressure, and subjective socioeconomic status as significant predictors, which is consistent with previous studies. However, several variables, including children’s overall happiness, frequency of using slang, preference for mathematics, school life preference, daily time spent for homework and study, average monthly cost of private education, parents’ participation in school events, marital conflict, and residential area, which were newly explored in the study, were also significant. Finally, we presented the significance and implications of the results in relation to decreasing academic stress among fourth-grade elementary school children.

该研究的主要目的是利用韩国儿童小组研究的数据，通过最小绝对收缩和选择算子（LASSO）正则化惩罚回归模型，探讨影响四年级小学生学业压力的主要预测因素。该研究使用 LASSO 模型检查了 280 个解释变量。经过数据预处理后，最终选择了21个变量。其中，研究发现儿童的坚持、同伴依恋、欺凌、父母的成就压力和主观社会经济地位是重要的预测因素，这与之前的研究一致。然而，有几个变量，包括孩子的整体幸福感、使用俚语的频率、对数学的偏好、学校生活的偏好、每天花在家庭作业和学习上的时间、私立教育的平均每月费用、父母对学校活动的参与、婚姻冲突和居住情况该研究中新探索的领域也很重要。最后，我们提出了该结果对于减轻四年级小学生学业压力的意义和影响。
