Research concerned with the relationship between volunteer activity and psychological well-being has typically reported higher levels of well-being among older adult volunteers relative to nonvolunteers. However, few studies have examined nonlinear associations between frequency of volunteer activity and well-being. We examined nonlinear associations between hours spent volunteering and psychological well-being, controlling for employment status, partner status, physical health, and education. We also investigated associations between different domains of volunteer activity and well-being, along with the possible moderating effects of gender on these relationships.
We used data from the PATH Through Life Project, a population-based study of Australian adults. Participants consisted of 2,136 older adults aged 64 to 68.
Nonlinear associations between hours spent volunteering and psychological well-being were evident, with these associations characterized by inverted U shapes, with nonvolunteers and those volunteering at high levels producing lower well-being scores relative to those volunteering at moderate levels. Few associations between specific domains of volunteer activity and well-being were evident, and no notable gender interactions emerged.
The results point toward optimal frequency of engagement in volunteer activity for psychological well-being as being bounded by upper and lower levels, outside of which benefits to well-being diminish.
有关志愿活动与心理健康之间关系的研究通常表明,相对于非志愿者,老年志愿者的幸福感水平更高。然而,很少有研究探讨志愿活动频率与幸福感之间的非线性关联。我们研究了志愿服务时长与心理健康之间的非线性关联,并控制了就业状况、伴侣状况、身体健康和教育程度等因素。我们还调查了志愿活动不同领域与幸福感之间的关联,以及性别对这些关系可能产生的调节作用。
我们使用了“人生之路项目”的数据,这是一项针对澳大利亚成年人的基于人群的研究。参与者包括2136名年龄在64至68岁之间的老年人。
志愿服务时长与心理健康之间存在明显的非线性关联,这些关联呈倒U形,非志愿者和高频率志愿者的幸福感得分低于中等频率志愿者。志愿活动特定领域与幸福感之间的关联不明显,也没有显著的性别交互作用出现。
研究结果表明,参与志愿活动以促进心理健康的最佳频率存在上下限,超出这个范围,对幸福感的益处就会减少。
