Key Takeaways

  • Loneliness impacts 20 million older adults and can go hand in hand with social isolation.

  • Lack of social connection can be more harmful to a person's health than smoking 15 cigarettes a day.

  • Health promotion workshops can help minimize social isolation and loneliness. Measuring such programs can help pinpoint what's working well.

Loneliness and social isolation are growing problems that can be particularly hard to combat in our pandemic-era world.

Yet a growing body of research shows small group programs, either online or in person, can go a long way toward improving people's sense of social connectedness.  And fostering social connectedness is important for everyone's overall health and well-being.

What's the difference between loneliness and social isolation?

Social isolation is an objective measure—defined as “a state in which the individual lacks a sense of belonging socially, lacks engagement with others, has a minimal number of social contacts, and [is] deficient in fulfilling and quality relationships.”1 It speaks to the existence and structure of interpersonal connections and social relationships in one’s life, such as a partner or spouse, a group of friends, or a room/house mate.

Loneliness, commonly defined as “a state of solitude or being alone”2 impacts approximately 20 million older adults. While many people associate loneliness with literally being alone, it is actually about someone's subjective feelings of being alone or isolated.

When discussed together, social isolation and loneliness fit under a larger umbrella concept of “social connectedness.”

Why pay attention to social connectedness for older adults?

Social disconnectedness is a serious and growing public health concern in the United States. Many factors contribute to rising rates of loneliness and social isolation, which negatively impact more people over time and drive up the cost of addressing social connectedness in terms of medical costs and health outcomes. When compared to other leading health indicators in the United States, loneliness impacts a greater number of adults than those classified as obese, severely obese, inactive, and smokers.3

Social disconnectedness has emerged as a substantial predictor of death in the United States, surpassing deaths associated with smoking 15 cigarettes a day, alcohol consumption, obesity, and air pollution.3 

Simply put, social disconnectedness puts adults at greater risk for underlying health issues such as dementia, heart disease, and even premature death.

How can I improve social connectedness for older adults?

Reducing social isolation and loneliness among older adults was the focus of a pre-pandemic study we conducted in Washington state with several partners. That study of adults ages 60-101 found up to half of them felt isolated, and one in five did not have the desired amount of contact with trusted people they feel close to.

Some tips we can all follow to improve social connectedness:

  • Take time to listen to older adults. Even if someone doesn’t have a large group of family or friends, it only takes one person to make them feel valued, connected, and supported.
  • Encourage older adults to be open to new activities and new people. Identifying common interests can form bonds, create purpose, and develop positive relationships.
  • Identify ways to introduce meaningful interactions in different settings. Consider phone and online services to bring people together.

How can small groups help with loneliness and social isolation?

Evidence-based health promotion programs have been extensively studied and shown to help older adults better manage their chronic conditions, improve quality of life, and lower health care costs. Just a few examples:

Beyond the well-documented health benefits, though, participating in small group, evidence-based health promotion programs connects older adults with others who may be experiencing similar health conditions or concerns so they don’t feel alone in their health journey. Many of the workshop activities, such as brainstorming how to create a healthier lifestyle, goal-setting together, and opening up about barriers to pursing healthy behaviors, can create a level of sharing that may not naturally happen in other venues.

How do you know if a program is effective against loneliness and social isolation?

To better understand the positive impact these health promotion programs might have on older adults’ loneliness and/or social isolation, measurement is key. Some reliable scales for measuring aspects of social connectedness:4

When selecting a measurement tool, be sure to consider the tool's:

  1.  appropriateness for the audience
  2. ability to identify the type of risk the organization is interested in addressing
  3. relevance to the programs and services being offered to address the risk

The thought of adding yet another task to already-streatched organization staff can be daunting. But gaining this level of understanding through data can add to an organization’s value proposition and improve efforts to secure more funding and expand partnerships. Stronger value  propositions can open doors for working with health care providers who are increasinglly shifting their focus to include social determinants of health.
