The objectives are to explore the relationship between study stress and anxiety in high school students and the mediating role of physical activity and mobile phone addiction.
A cross-sectional study.
129 high schools were randomly selected in 13 cities of Jiangsu province, China.
High school students aged 16-19 years, age and gender balance. A total of 40 000 questionnaires were distributed, with 32 974 effectively recovered.
Questionnaires were administered offline, covering four parts: General Demographics, Learning Stress Scale, International Physical Activity Questionnaire, Mobile Phone Addiction Scale and Generalized Anxiety Scale-7. Data analysis included path analysis and correlation analysis, along with descriptive statistics, independent sample t-test, correlation analysis and structural equation model.
In this study, the proportions of anxiety, high academic pressure, low physical activity level and high mobile phone addiction were 58.18%, 46.48%, 36.40% and 39.26%, respectively. Study stress was positively correlated with anxiety (r=0.130, p<0.01) and mobile phone addiction (r=0.049, p<0.01). Physical activity was negatively correlated with learning stress (r=-0.352, p<0.01), anxiety (r=-0.105, p<0.01) and mobile phone addiction (r=-0.040, p<0.01). The findings were tested by mediating effect analysis that the indirect effect size value of the path 'learning stress → physical activity level → anxiety path' was 0.461, 95% CI of Bootstrap (0.367, 0.554), the mediating effect was significant. The indirect effect size value of the path 'learning stress → mobile phone addiction → anxiety' was 0.072, 95% CI of Bootstrap (0.042, 0.102), and the mediating effect was significant. The indirect effect size value of the path 'learning stress → physical activity level → mobile phone addiction → anxiety' was 0.072, and the 95% CI of Bootstrap (0.226, 0.400), and the mediating effect was significant.
High school students' learning stress can significantly positively predict anxiety levels. High school students learning stress indirectly predicts anxiety through the independent mediating effect of physical activity and mobile phone addiction, as well as the chain mediating effect of physical activity and mobile phone addiction.
探讨高中生学习压力与焦虑的关系，以及身体活动和手机成瘾在其中的中介作用。
横断面研究。
中国江苏省 13 个城市的 129 所高中。
年龄在 16-19 岁的高中生，年龄和性别均衡。共发放 40000 份问卷，有效回收 32974 份。
问卷采用线下方式进行，涵盖四个部分：一般人口统计学、学习压力量表、国际体力活动问卷、手机成瘾量表和广泛性焦虑量表-7。数据分析包括路径分析和相关分析，以及描述性统计、独立样本 t 检验、相关分析和结构方程模型。
本研究中，焦虑、高学业压力、低身体活动水平和高手机成瘾的比例分别为 58.18%、46.48%、36.40%和 39.26%。学习压力与焦虑（r=0.130，p<0.01）和手机成瘾（r=0.049，p<0.01）呈正相关。身体活动与学习压力（r=-0.352，p<0.01）、焦虑（r=-0.105，p<0.01）和手机成瘾（r=-0.040，p<0.01）呈负相关。通过中介效应分析检验发现，路径“学习压力→身体活动水平→焦虑路径”的间接效应大小值为 0.461，Bootstrap 的 95%置信区间（0.367，0.554），中介效应显著。路径“学习压力→手机成瘾→焦虑”的间接效应大小值为 0.072，Bootstrap 的 95%置信区间（0.042，0.102），中介效应显著。路径“学习压力→身体活动水平→手机成瘾→焦虑”的间接效应大小值为 0.072，Bootstrap 的 95%置信区间（0.226，0.400），中介效应显著。
高中生的学习压力可显著正向预测焦虑水平。高中生学习压力通过身体活动和手机成瘾的独立中介效应以及身体活动和手机成瘾的链式中介效应间接预测焦虑。
