Combating Loneliness in Older Adults during the COVID-19 Pandemic: Findings from a Volunteer-Based Program in Greece

The COVID-19 pandemic has exacerbated the feeling of loneliness, especially among older adults. This study aims to investigate any association between COVID-19 cases in Greece and the number of Loneliness Helpline calls at the Friendship at Every Age program and to assess whether the interconnection part of the program, which interconnects older adults with volunteers, can combat loneliness/social isolation in older adults. This is a supportive, volunteer-based, social intervention program. A total of 4033 calls were collected from July 2020 to November 2022, in Greece. Older adults who participated in the interconnection part completed baseline (n = 275) and follow-up questionnaires (n = 168), including the UCLA Loneliness Scale. A time-series analysis revealed a positive association in the number of calls with COVID-19 cases (Incidence Rate Ratio per 100 new COVID-19 cases = 1.012; Confidence Interval (95% CI) [1.002, 1.022]). A significant decrease in the Loneliness Scale was observed at follow-up [difference = −0.85; 95% CI (−1.16, −0.54)], with similar results by sex, educational level, and area of living. Loneliness Helpline calls increased during COVID-19 outbreaks, while the interconnection part had a positive impact on older adults, reducing their feeling of loneliness. Similar initiatives are required to better address the needs of the ageing population during and after health crises.
