The natural state of human beings is to live together and function as organized groups. The beginnings of communities have primeval origins; evolutionarily, societies that worked together were more productive, efficient and—probably most important—safer. Thousands of years of evolution have ingrained these behaviors as part of our genetic constitution and developmental process. Social integration and acceptance thus are an integral part of basic human behavior and provide a sense of protection, pleasure, and purpose in life.
Unfortunately, the social isolation necessary to address the coronavirus disease 2019 (COVID-19) pandemic is preventing this integration, and is likely to worsen what some have called an epidemic of loneliness. As mental health clinicians, we need to use technology to strengthen our patients’ social support systems.
Loneliness: A growing problem
Changes in society over the last few decades have led to increased isolation. In the last 50 years, there has been a rise in single-person households in the United States. This is most common in large cities, where the prevalence is approximately 40%.1 The average number of confidants or the size of an American’s social network reduced by more than one-third from 1985 to 2009.2 In a study published in 2018, the health service company Cigna used the UCLA Loneliness Scale to survey >20,000 American adults.3 Nearly half of respondents reported always feeling alone (46%) or left out (47%), and individuals age 18 to 22 were the loneliest age group and claimed to be in worse health than older age groups. Furthermore, the results suggested that people who felt lonelier were more likely to have poor sleep and be less physically active. Americans who lived with others were less likely to report feeling lonely, except for single parents living only with their children. The results also showed that people who engage in meaningful interactions with others had lower loneliness scores and perceived that they were in better overall health.3
Studies have consistently demonstrated a link between loneliness and health problems such as cardiovascular disease, substance use disorders (SUDs), and mood disorders. A 2010 meta-analysis of 148 prospective studies with 308,849 participants found that the influence of social relationships on the risk of mortality is comparable to well-established risk factors for mortality such as smoking and alcohol consumption.4 These findings were confirmed in a 2015 meta-analysis that included 70 studies with 3.4 million participants followed for an average of 7 years. 5
Loneliness has been identified as a social determinant of health and is considered by many to be epidemic in proportion in developed countries. According to a 2019 Business Insider survey, almost 20% of US health care leaders planned to address social isolation in the next 12 months.6
Increased vulnerability during COVID-19 isolation
The forced quarantines and social distancing imposed by the COVID-19 crisis are likely to further exacerbate the loneliness epidemic. Hopefully, this increased isolation will not last more than several months, and its effect on chronic medical illnesses will be minor. However, for patients with mental illness, this further isolation, in conjunction with rising societal anxiety and fear of the potentially devastating financial consequences, could worsen their illness, and might even lead to suicidal ideation or behavior.
Individuals with SUDs are particularly vulnerable to the social limitations required by COVID-19. While social isolation is essential to limit the spread of COVID-19, this restriction poses unique challenges for these patients because connection and social support are important aspects of achieving and maintaining sobriety.7
