Not only do people with cognitive impairment experience poor quality of life when anxiety is present, their family caregivers also experience more stress. Findings from prior research suggests that poor social relationships with partners, poor social support, and fewer social activities contribute to anxiety in older adults.Ī high anxiety prevalence is also reported in older adults with cognitive impairment. According to previous literature, a leading factor associated with anxiety in older adults is feeling of isolation. It is reported that up to 52.3% of older adults living at home experience anxiety. Īnxiety is extremely common in older adults. Older adults experiencing social isolation may often show signs of negative responses, such as anxiety. However, approximately a quarter of community-dwelling older adults living in the United States are socially isolated. Maintaining social relationships and a social support system is especially important in older adults as it is considered as part of successful aging.

When there is a discrepancy between desired and actual interpersonal relationships, people tend to perceive social isolation. Tailored interventions targeting both people with or without cognitive impairment are needed to lessen social isolation and anxiety.Ī lack of one’s social resources, such as companionship and social support, is known as social isolation. The relationship between social isolation and anxiety was a universal phenomenon regardless of cognitive status. Regression analyses showed that increased social isolation over time was related to increased anxiety over 5 years regardless of cognitive status after controlling for covariates ( p = 0.017). ResultsĪt the 5-year follow up, there were statistically significant differences in social isolation between the three groups ( p = 0.043). Weighted linear regression analyses with a group interaction were used to examine the moderating effect of cognitive impairment on the relationship between changes in social isolation and anxiety. The participants were categorized into three groups: Participants who developed probable dementia over 5 years (4.3%), developed probable MCI (19.1%), or maintained normal cognitive function (76.6%). MethodsĪ secondary data analysis was conducted using the National Social Life, Health, and Aging Project (NSHAP): Wave 2 (2010–2011) and Wave 3 (2015–2016). Therefore, this study was conducted to (1) compare the level of social isolation and anxiety in older adults who developed probable dementia and mild cognitive impairment (MCI) to those who maintained normal cognitive function over 5 years and (2) determine if cognitive impairment moderates the relationship between changes in social isolation and changes in anxiety over 5 years. However, what is unknown is how the relationship between social isolation and anxiety differs by cognitive status.

Anxiety is common in older adults and social isolation is one of the leading factors associated with their anxiety.
