■大学生的负面情绪是影响心理健康的重要因素,消极情绪引起的自杀行为呈逐年上升趋势。现有研究表明,体育锻炼对缓解负面情绪至关重要,然而,它影响负面情绪的内在机制尚未完全揭示。
■大学生的负面情绪是影响心理健康的重要问题。本研究调查了大学生体育锻炼与负性情绪的关系,以睡眠质量和自测健康(SRH)为中介,分析体育锻炼影响学生负面情绪的途径机制。
■采用了横断面研究设计,采用在线问卷进行调查。量表包括身体活动评定量表-3(PARS-3),抑郁焦虑应激量表-21(DASS-21),匹兹堡睡眠质量指数(PSQI)和12项简式健康调查(SF-12),共收集有效问卷30475份,的有效性为91%。采用链式调解试验和Bootstrap方法进行效果分析。
■从事大学生的比例低,中等,高水平的体育锻炼分别为77.6、13.1和9.3%,分别。经历“非常严重”压力水平的学生比例,焦虑,抑郁症分别为4.5%、10.9%和3.6%,分别。体育锻炼与自测健康呈显著正相关(r=0.194,p<0.01),与睡眠质量呈显著负相关(r=-0.035,p<0.01),与压力显著负相关,焦虑,和抑郁(r=-0.03,p<0.01;r=-0.058,p<0.01;r=-0.055,p<0.01)。睡眠质量与自测健康呈显著负相关(r=-0.242,p<0.01)。中介效应测试表明,睡眠质量和自评健康部分介导了体育锻炼和负面情绪之间的关系,总效应,总的直接效应,和总间接效应值分别为-1.702、-0.426和-1.277。
■大学生主要从事低强度体力活动。睡眠质量和自测健康是体育锻炼对学生负面情绪影响的中介。一定程度的体育锻炼可以直接影响学生的情绪状态,并通过睡眠和自我评估的健康状况间接影响他们的负面情绪。定期参加体育活动主要通过增强情绪稳定性和整体情绪韧性来积极影响情绪状态。
UNASSIGNED: Negative emotions in college students are a significant factor affecting mental health, with suicide behaviors caused by negative emotions showing an annual increasing trend. Existing studies suggest that physical exercise is essential to alleviate negative feelings, yet the intrinsic mechanisms by which it affects negative emotions have not been fully revealed.
UNASSIGNED: Negative emotions in college students represent a significant issue affecting mental health. This study investigates the relationship between physical exercise and negative emotions among college students, incorporating sleep quality and self-rated health (SRH) as mediators to analyze the pathway mechanism of how physical exercise affects students\' negative emotions.
UNASSIGNED: A cross-sectional study design was utilized, employing online questionnaires for investigation. The scales included the Physical Activity Rating Scale-3 (PARS-3), the Depression Anxiety Stress Scales-21 (DASS-21), the Pittsburgh Sleep Quality Index (PSQI), and the 12-Item Short Form Health Survey (SF-12), resulting in the collection of 30,475 valid questionnaires, with a validity rate of 91%. Chain mediation tests and Bootstrap methods were applied for effect analysis.
UNASSIGNED: The proportions of university students engaged in low, medium, and high levels of physical exercise were 77.6, 13.1, and 9.3%, respectively. The proportions of students experiencing \"very severe\" levels of stress, anxiety, and depression were 4.5, 10.9, and 3.6%, respectively. Physical exercise was significantly positively correlated with self-rated health (r = 0.194, p < 0.01), significantly negatively correlated with sleep quality (r = -0.035, p < 0.01), and significantly negatively correlated with stress, anxiety, and depression (r = -0.03, p < 0.01; r = -0.058, p < 0.01; r = -0.055, p < 0.01). Sleep quality was significantly negatively correlated with self-rated health (r = -0.242, p < 0.01). Mediation effect testing indicated that sleep quality and self-rated health partially mediated the relationship between physical exercise and negative emotions, with total effect, total direct effect, and total indirect effect values of -1.702, -0.426, and - 1.277, respectively.
UNASSIGNED: College students primarily engage in low-intensity physical activity. Sleep quality and self-rated health mediate the impact of physical exercise on students\' negative emotions. A certain level of physical activity can directly affect students\' emotional states and indirectly influence their negative emotions via sleep and self-rated health. Regular engagement in physical activities primarily positively impacts emotional states by enhancing mood stability and overall emotional resilience.
