While literature has displayed a link between psychological well-being (i.e. depression, hopelessness, and life satisfaction) and health-risk behaviors (i.e. smoking, drinking, suicide, and physical inactivity), the mechanisms underlying this relationship have received little empirical attention. This study examines the mediation effects of social support (from family, friends, and significant others) that accounted for the link. Participants were 2023 university students (47.7% male). Structural equation modeling showed partial mediation effect of social support between psychological well-being and health-risk behaviors. In particular, social support from family and friends jointly mediated about 80 percent of the effect of life satisfaction and hopelessness on drinking. These results offered novel evidence that helps improve theorizing the mechanisms of the relationship between psychological well-being and health-risk behaviors. They also highlighted the potential benefits of social support for university students to help them stay healthy. The implications of these results are discussed.
虽然文献表明心理健康（即抑郁、绝望和生活满意度）与健康风险行为（即吸烟、饮酒、自杀和缺乏体育锻炼）之间存在联系，但这种关系背后的机制很少受到实证关注。本研究考察了社会支持（来自家人、朋友和重要他人）在这种联系中所起的中介作用。参与者为2023名大学生（47.7%为男性）。结构方程模型显示社会支持在心理健康与健康风险行为之间存在部分中介作用。具体而言，来自家人和朋友的社会支持共同介导了生活满意度和绝望感对饮酒影响的约80%。这些结果提供了新的证据，有助于完善对心理健康与健康风险行为之间关系机制的理论阐释。它们还凸显了社会支持对大学生保持健康的潜在益处。本文讨论了这些结果的意义。
