Marital-history differences in increased loneliness during the COVID-19 pandemic: A European study among older adults living alone

The COVID-19 pandemic and related physical distancing measures have disproportionally affected older adults living alone due to their greater social isolation. Unlike previous studies on the subject, the current research recognizes the diversity amongst older adults living alone by considering the impact of marital history. Combining information from Wave 8 of the Survey of Health Ageing and Retirement (SHARE), with data of SHARELIFE and the SHARE Corona survey, we investigated the differential impact of the COVID-19 pandemic on loneliness in older men (N = 1504) and women (N = 4822) living alone. Logistic multilevel analyses were performed on data from 26 European countries and Israel. For men, we found that the short-term widowed were more likely to report increased loneliness than the medium- and long-term widowed and those living apart together (LAT). For women, the results indicated that the short- and medium-term widowed and the divorced were at greater risk for increased loneliness than those in a LAT relationship. Also, medium-term widowed women were more likely to report increased loneliness than their long-term widowed counterparts. The three hypothesized underlying mechanisms - i.e., (i) the opportunity mechanism, (ii) the expectation mechanism, and (iii) the vulnerability mechanism - only played a small role in explaining the observed differences. In sum, our study highlights the importance of recognizing the diversity within the group of older adults living alone when investigating the effects of the pandemic on loneliness, yet the mechanisms behind the stratifying role of marital history are not fully understood.
