A new study from the University of Toronto identifies three key factors linked to strong mental health in older adults. The findings were published in the journal PLOS One.
Researchers analyzed data from over 2,000 respondents aged 65 and older from Statistics Canada’s 2022 Mental Health and Access to Care Survey. They aimed to understand what constitutes “complete mental health.” The study defines this as a combination of three things: the absence of a psychiatric disorder, experiencing happiness or life satisfaction almost daily for the past month, and having social and psychological well-being almost daily for the past month.
Daniyal Rahim, the first study author and a Ph.D. candidate, stated that the findings shift the focus from mental illness alone to understanding what helps older adults flourish. He said complete mental health reflects not just the absence of disorders, but the presence of meaning, satisfaction, and strong social connections.
Social Connections
Strong social connections were a major factor. The data showed that older adults who were married and had strong social support were more likely to experience complete mental health. In fact, having social support doubled the odds.
Study co-author Shannon Halls said social relationships appear to be a cornerstone of mental well-being in later life. She added that having people to rely on during stressful times may help buffer against psychological distress and promote resilience, happiness, and a sense of purpose.
Good Physical Health
Good physical health was another important factor. Adults who rated their physical health as fair or better, and who reported no chronic pain, sleep problems, or limitations in daily activities, were more likely to have complete mental health.
The study also found that living in a rural area was more strongly associated with complete mental health than living in an urban area.
A Strong Sense of Spirituality
Spirituality was a third significant factor. Participants who said religion or spirituality was important in their daily lives were much more likely to achieve complete mental health.
Study co-author and epidemiologist Ying Jiang said spiritual beliefs may help older adults cope with adversity by providing meaning, hope, and a sense of community. She noted these factors can be particularly relevant during periods of declining health or major life changes.
The study authors hope the results can lead to more targeted interventions, such as social programs or pain-management support, to improve mental health in aging populations. They suggest that focusing on physical health, community engagement, and spirituality can contribute to well-being.
The research builds on a growing body of work examining holistic well-being in older demographics. Previous studies have often highlighted the interconnectedness of physical and mental health, but this analysis specifically quantifies the combined impact of social, physical, and spiritual factors on a state of complete mental health in seniors.
