This study investigated how perceived stress, social support, and home-based physical activity affected older adults' fatigue, loneliness, and depression. We also explored whether social support and physical activity mediated the relationships between stress and mental health problems. The data of 163 older participants were analyzed in this study. Structural equation modeling using LISREL 8.71 was performed to assess the effects of stress, support, and physical activity on mental health. The findings indicate that perceived stress predicted higher levels of depression, social support predicted lower levels of loneliness and fatigue, and physical activity predicted lower levels of fatigue among older adults. Social support and physical activity mediated the relationships between stress and mental health, except depression. In conclusion, the relative impacts of perceived stress, social support, and physical activity on types of mental health (e.g., fatigue, loneliness, and depression) were different. Furthermore, stress had direct and indirect effects on each construct of mental health (e.g., fatigue, loneliness, and depression).
本研究调查了感知压力、社会支持和居家体育活动如何影响老年人的疲劳、孤独感和抑郁情绪。我们还探讨了社会支持和体育活动是否介导了压力与心理健康问题之间的关系。本研究分析了163名老年参与者的数据。使用LISREL 8.71进行结构方程建模，以评估压力、支持和体育活动对心理健康的影响。研究结果表明，感知压力预示着老年人抑郁水平较高，社会支持预示着孤独感和疲劳水平较低，体育活动预示着老年人疲劳水平较低。社会支持和体育活动介导了压力与心理健康（抑郁除外）之间的关系。总之，感知压力、社会支持和体育活动对心理健康类型（如疲劳、孤独感和抑郁）的相对影响各不相同。此外，压力对心理健康的各个构成要素（如疲劳、孤独感和抑郁）有直接和间接影响。
