China, which is deeply influenced by Confucianism, places special emphasis on students' test scores. Previous studies have shown that neuroticism is associated with irritable bowel syndrome (IBS) in adolescents. However, the mechanisms underlying this association before exams in female secondary school students are unknown. The present study sought to ascertain whether IU mediates the association between neuroticism and pre-exam IBS, and to determine whether exercise duration moderates the relationship between neuroticism and pre-exam IBS.
The sample consisted of 685 Chinese female middle school students (M = 14.81, SD = 1.55, range = 11-18) who completed paper questionnaires, including the neuroticism subscale of the Chinese Neuroticism Extraversion Openness Five-Factor Inventory, the IBS Symptom Severity Scale, a simplified version of the Intolerance of Uncertainty Scale, and a movement time questionnaire. Independent samples t-test was used to compare differences between groups and Pearson correlation coefficient was used to investigate the bivariate correlation. The SPSS PROCESS 4.1 plug-in was then used to examine the mediating role of IU as well as the moderating role of movement time between neuroticism and pre-exam IBS.
Neuroticism and IU were significantly correlated with pre-exam IBS ( = 0.39, 0.30, respectively; all < 0.01), and neuroticism was significantly correlated with IU ( = 0.46, < 0.01). Neuroticism had a direct predictive effect on pre-exam IBS in Chinese female middle school students ( = 0.32, < 0.001), and IU also had a positive effect on pre-exam IBS ( = 0.15, < 0.001). The mediating effect value of IU on the total effect was 18.09%. The relationship between neuroticism and pre-exam IBS was moderated by movement time ( = -0.23, < 0.05).
IU plays a mediating role between neuroticism and pre-exam IBS, and exercise time plays a moderating role between neuroticism and pre-exam IBS. These findings provide an evidence for neuroticism intervention, IU management, and pre-exam IBS improvement in female middle school students.
深受儒家思想影响的中国特别重视学生的考试成绩。以往研究表明，神经质与青少年肠易激综合征（IBS）有关。然而，女中学生考试前这种关联的潜在机制尚不清楚。本研究旨在确定不确定性不耐受（IU）是否介导神经质与考试前IBS之间的关联，并确定运动时长是否调节神经质与考试前IBS之间的关系。
样本包括685名中国女中学生（M = 14.81，SD = 1.55，范围 = 11 - 18岁），她们完成了纸质问卷，包括中国神经质外向开放性五因素量表的神经质分量表、IBS症状严重程度量表、不确定性不耐受量表简版和运动时间问卷。采用独立样本t检验比较组间差异，采用Pearson相关系数研究双变量相关性。然后使用SPSS PROCESS 4.1插件来检验IU的中介作用以及运动时间在神经质与考试前IBS之间的调节作用。
神经质和IU与考试前IBS显著相关（分别为 = 0.39、0.30；均 < 0.01），神经质与IU显著相关（ = 0.46， < 0.01）。神经质对中国女中学生考试前IBS有直接预测作用（ = 0.32， < 0.001），IU对考试前IBS也有正向作用（ = 0.15， < 0.001）。IU对总效应的中介效应值为18.09%。神经质与考试前IBS之间的关系受运动时间调节（ = -0.23， < 0.05）。
IU在神经质与考试前IBS之间起中介作用，运动时间在神经质与考试前IBS之间起调节作用。这些发现为女中学生的神经质干预、IU管理和考试前IBS改善提供了证据。
