Psychosocial Determinants of Loneliness in the Era of the COVID-19 Pandemic-Cross-Sectional Study

Loneliness and depression in older adults with multimorbidity: the role of self-efficacy and social support

Introduction

As relatively little is known about self-efficacy and social support in individuals aged 65 years and older and whether they are facing a decline in life due to multimorbidity and previous COVID-19 infection, this study investigated hypotheses based on Social Cognitive Theory.

Methods

It was tested whether depressive symptoms in multimorbid patients who were hospitalized for COVID-19 infection, and recover post infection during their hospital stay, do not differ from those of multimorbid patients hospitalized for other conditions. Furthermore, we tested whether depressive symptoms are associated with increased loneliness scores, low self-efficacy beliefs, and poorly perceived social support. Additionally, it was investigated whether self-efficacy is a mediator variable, and social support is a moderator variable between loneliness and depression. N = 135 patients with or without previous COVID-19 infection (mean age 64.76) were recruited. Paper questionnaires were collected at the time of inpatient hospital admission in the year 2021 and in a cross-sectional study design. The study compared n = 45 multimorbid patients who survived COVID-19 infection with those n = 90 who were not infected before.

Results

No significant difference in depressive symptomology between these two groups revealed [t(133) = 130, p = 0.90, d = 0.024); F(3, 122) = 0.255, p = 0.86]. The study found a positive correlation between loneliness and anxiety and depression in both groups (rdepression = 0.419 and ranxiety = 0.496). Self-efficacy mediated the relation between loneliness and depression. The completely standardized indirect effect was β = 0.111, percentile Bootstrap 95% CI 0.027-0.201.

Discussion

The research findings suggest the importance of self-efficacy, and loneliness in the development of depressive symptoms, and have several practical implications for improving the mental health of multimorbid patients: Prospectively, treatment should not only focus on physical and cognitive health, but also on promoting self-efficacy and perceived social support, as well as address loneliness with psychoeducational interventions. Replication of the findings and conducting interventional research also employing lifestyle components should follow up, as this study tested associations but no causal relationships.

Differences in Loneliness and Social Isolation among Community-Dwelling Older Adults by Household Type: A Nationwide Survey in Japan

(1) Background: Social isolation and loneliness are determinants of healthy longevity. However, previous research has focused on either social isolation or loneliness and has not considered household types. This study sought to clarify loneliness and social isolation among older adults using single-person (ST) or multi-person (MT) household types. (2) Methods: We administered a national, anonymous, self-administered survey to 5351 Japanese older adults aged 65 years or older. The survey included subjects' demographic characteristics and scores for loneliness (University of California Los Angeles (UCLA) Loneliness Scale version 3 (Cronbach's α = 0.790)), social isolation (Lubben Social Network Scale (LSNS-6) (Cronbach's α = 0.82)), and self-efficacy (GSES). (3) Results: After adjusting for age and gender, ST individuals had significantly lower LSNS-6 and significantly higher UCLA scores than MT individuals (p < 0.001). Lower LSNS-6 and higher UCLA scores were significantly associated with lower GSES scores, and the effect of GSES was greater for ST than for MT (LSNS-6, ST (β = 0.358, p < 0.001); MT (β = 0.295, p < 0.001)) (UCLA, ST (β = -0.476, p < 0.001); MT (β = -0.381, p < 0.001)). (4) Conclusions: Specific healthcare systems and programs based on self-efficacy should be developed by household type to reduce both social isolation and loneliness.
