Internet usage buffers the effect of loneliness on subjective health among informal caregivers of older adults.

Abstract

Informal caregivers of older adults usually suffer from loneliness, which makes them vulnerable to reduced health outcomes. This study attempted to explore whether internet usage mitigates the effects of loneliness on subjective health among informal caregivers of older adults. A sample of 1089 informal caregivers (mean age = 58.0 ± 15.7 years, 60.3% females) providing unpaid cares for older adults in the United States were investigated. Their loneliness, subjective health, and utilization of caregiving-related online resources were measured. Descriptive statistics and correlation analyses were conducted to summarize the sample's characteristics and determine the relationships among the study variables, respectively. Finally, a multivariate regression analysis with an interaction term was performed to test the moderating effect of internet usage. Results indicated that loneliness was significantly negatively associated with subjective health. Furthermore, after controlling for demographic and caregiving-related factors, the moderating effect of internet usage on the link between loneliness and subjective health was significant, namely, the negative association between loneliness and subjective health was less pronounced at higher levels of internet usage. Hence, in addition to alleviating loneliness, providing caregiving-related online services and promoting positive utilization of resources on the internet may be potential intervention targets to improve informal caregivers' health.
