■大学生表现出很高的压力,焦虑,和抑郁症,医学和护理学生的心理健康挑战水平特别高。乐观通过促进健康的生活方式和认知反应来显着影响整体幸福感。然而,乐观与睡眠质量的关系,压力,大学生的心理健康仍有待探索。本研究旨在(1)探讨乐观情绪与睡眠质量的关系,压力,(2)确定睡眠质量和压力是否介导大学生乐观与心理健康之间的关系。
■2022年9月至12月,对美国东北部一所公立大学的健康科学专业学生进行了一项横断面研究。共有222名学生参加了这项研究,提供社会人口统计数据,乐观,睡眠质量,压力,焦虑,和抑郁症。使用并行和串行调解模型来检查睡眠质量和压力在乐观与心理健康之间的关联中的潜在中介作用。
■研究发现,乐观通过直接和间接途径影响焦虑和抑郁。根据预测,平行中介分析显示,乐观情绪对焦虑(βtotal=-0.598,95%置信区间[CI]:-0.778~-0.392)和抑郁(βtotal=-0.724,95%CI:-0.919~-0.519)的影响是由压力和睡眠质量介导的.此外,系列中介模型显示,压力和睡眠质量共同介导了乐观与焦虑(间接效应[IE]=-0.074,95%CI:-0.135~-0.029)或抑郁(IE=-0.084,95%CI:-0.142~-0.036)之间的关系。
■乐观与睡眠质量差呈负相关,压力,焦虑,和抑郁症。增强的乐观情绪与高睡眠质量和较少的压力有关,焦虑,和抑郁症。这些见解强调了以学校为基础的乐观干预措施改善睡眠质量的潜力。改善与压力相关的问题,缓解大学生的心理健康挑战。
UNASSIGNED: College students showed a high prevalence of stress, anxiety, and depression, with medical and nursing students experiencing particularly elevated levels of mental health challenges.Optimism significantly influences overall well-being by promoting a healthy lifestyle and cognitive responses. However, the association of
optimism with sleep quality, stress, and mental health in college students remains unexplored. This study aimed to (1) explore the associations of
optimism with sleep quality, stress, and mental health and (2) ascertain whether sleep quality and stress mediate the association between
optimism and mental health among college students.
UNASSIGNED: A cross-sectional study was conducted using online surveys with students from health science majors at a public university in the northeast United States from September to December 2022. A total of 222 students participated in the study, providing data on sociodemographics,
optimism, sleep quality, stress, anxiety, and depression. Parallel and serial mediation models were utilized to examine the potential mediating roles of sleep quality and stress in the association between optimism and mental health.
UNASSIGNED: The study found that optimism influences anxiety and depression through both direct and indirect pathways. In line with predictions, the parallel mediation analysis revealed that the impact of optimism on anxiety (βtotal = -0.598, 95% confident interval [CI]: -0.778 to -0.392) and depression (βtotal = -0.724, 95% CI: -0.919 to -0.519) was mediated by stress and sleep quality. Furthermore, the serial mediation models revealed that stress and sleep quality co-mediated the relationship betweenoptimism and anxiety (indirect effect [IE] = -0.074, 95% CI: -0.135 to -0.029) or depression (IE = -0.084, 95% CI: -0.142 to -0.036) in a sequential manner.
UNASSIGNED: Optimism was negatively correlated with poor sleep quality, stress, anxiety, and depression. Enhanced
optimism was linked to high sleep quality and less stress, anxiety, and depression. These insights emphasize the potential for school-based optimism interventions to improve sleep quality, ameliorate stress-related concerns, and alleviate mental health challenges in college students.
