Bereavement and grief are frequently experienced during the COVID-19 pandemic given widespread mortality. However, losses extend beyond deaths to include cancelled plans and routines, separation from family and friends, and unemployment. It is essential to better understand the multifaceted and complex losses experienced by older adults throughout the pandemic. We analysed 2,587 open-ended survey responses collected online in May to July 2020 from the COVID-19 Coping Study, a mixed-methods study of US adults aged 55 and older. Participants were on average 67 years old (standard deviation = 7.2), over two-thirds female and largely white. Qualitative thematic analysis identified diverse sources of grief, sadness and loss. Themes ranged from death and bereavement to anticipatory grief, loss of agency, cancelled plans and missed milestones, losing social contact and physical touch, health struggles, loss of normalcy and daily routines, and societal and economic woes. The results highlight the varied and highly personal nature of everyday grief and loss among ageing adults during the COVID-19 pandemic. Sources of grief extended beyond death to include both tangible and intangible losses with expectations of long-term consequences. These findings may inform the development of family and community supports, including mental health services, to address complex subjective experiences of grief and loss since the pandemic onset. Interventions are needed to support healing and hope in vulnerable and resilient ageing populations.
