The purpose of this study is to examine the effects of motives for volunteering on respondents' mortality risk 4 years later.
Logistic regression analysis was used to examine whether motives for volunteering predicted later mortality risk, above and beyond volunteering itself, in older adults from the Wisconsin Longitudinal Study. Covariates included age, gender, socioeconomic variables, physical, mental, and cognitive health, health risk behaviors, personality traits, received social support, and actual volunteering behavior.
Replicating prior work, respondents who volunteered were at lower risk for mortality 4 years later, especially those who volunteered more regularly and frequently. However, volunteering behavior was not always beneficially related to mortality risk: Those who volunteered for self-oriented reasons had a mortality risk similar to nonvolunteers. Those who volunteered for other-oriented reasons had a decreased mortality risk, even in adjusted models.
This study adds to the existing literature on the powerful effects of social interactions on health and is the first study to our knowledge to examine the effect of motives on volunteers' subsequent mortality. Volunteers live longer than nonvolunteers, but this is only true if they volunteer for other-oriented reasons.
本研究旨在探讨志愿者动机对 4 年后受访者死亡率的影响。
采用逻辑回归分析,检验在威斯康星纵向研究中,志愿者动机是否能预测老年人在参与志愿服务之外的未来死亡率风险。协变量包括年龄、性别、社会经济变量、身体、精神和认知健康、健康风险行为、人格特质、获得的社会支持以及实际的志愿服务行为。
与之前的研究结果一致,志愿者在 4 年后的死亡率风险较低,特别是那些更经常、更频繁地参与志愿服务的志愿者。然而,志愿服务行为并不总是与死亡率风险呈有益关系:出于自我导向原因参与志愿服务的志愿者的死亡率风险与非志愿者相似。出于其他导向原因参与志愿服务的志愿者的死亡率风险降低,即使在调整后的模型中也是如此。
本研究增加了关于社会互动对健康的强大影响的现有文献,并首次研究了动机对志愿者随后死亡率的影响。志愿者的寿命比非志愿者长,但前提是他们出于其他导向原因参与志愿服务。
