A Psychometric Analysis of the 20-item Revised University of California Los Angeles Loneliness Scale Among Korean Older Adults Living Alone

Relationship between qualitative and quantitative loneliness and suicidal ideation by occupational classification in the working-age population: a nationally-representative survey

BACKGROUND

Rising digitalization and individualism in the workplace after the COVID-19 pandemic have increased loneliness and related problems in the working-age population. The potential effects of various forms of loneliness on suicidal ideation may differ depending on employment status.

METHOD

This is a cross-sectional study based on a national survey of mental health in the general Korean population. We classified occupations as "employed," "self-employed," or "unemployed." Loneliness was assessed using the UCLA Loneliness Scale, which measures both qualitative and quantitative aspects of loneliness. Suicidal ideation was evaluated using the Patient Health Questionnaire-9.

RESULTS

A total of 1770 participants aged 30-65 years (mean age: 47.7 years) were included. The mean loneliness score was 43.9 (SD = 10.4), and 28% of the participants experienced a high level of loneliness. The prevalence ratio for suicidal ideation in the group with high levels of loneliness was 3.06 (95% CI 2.57, 3.63) compared to the group with low levels of loneliness. In our subgroup analysis, we consistently observed an association between loneliness and suicidal ideation across the employed group; however, the employed was more related with qualitative loneliness, the self-employed and the unemployed were more related with quantitative loneliness.

CONCLUSIONS

Loneliness was associated with suicidal ideation. According to employment status, the associations were consistent, but there were interactions between type of loneliness and employment status. These findings suggest that interventions to reduce loneliness and prevent suicidal ideation should be tailored to specific employment groups, focusing on qualitative aspects for employed individuals and quantitative aspects for self-employed and unemployed individuals.

Addressing adolescent social and emotional concerns: Insights from loneliness, burnout, and preferred conversation topics in Asian and UK contexts post-pandemic

This study investigated relationships between social and emotional concerns, loneliness, and school burnout, as these factors are associated with adaptive functioning during adolescence residence in Asia (i.e., China, Hong Kong) and the UK. Analysis of data from 2849 participants illuminated compelling insights. The participants reported a high level of loneliness, notably among girls in the UK. The research generated 11 preferred conversation topics (i.e., future and aspirations, anything, learning, nothing, mental health, personal interests, health, relationships, psychosocial issues, social issues, feelings). Among them, future and aspirations lead the way, aligning with developmental needs. A desire for mental health discussions coexisted with heightened loneliness and burnout among participants who pursued such conversations. The low achievers tended to talk about mental health issues or have nothing to say. High achievers were drawn to social issues, emphasizing their distinct socio-emotional needs. Forging a connection between personal interests and mitigated school burnout underscores the potential for individual passions to harmonize with educational experience. These findings underscore the exigency for bespoke interventions addressing the evolving emotional terrain of adolescents, especially in the pandemic's aftermath. The study's implications underscore the importance of empathetic listening and proactive engagement between adolescents and supportive adults. This research enriches the comprehension of pandemic-induced adolescent experiences and suggests avenues for future investigations into long-term emotional well-being.

Exploring Loneliness, Trust, and Psychosocial Meanings Among Primary Care Attendees: A Cross-Sectional Study From a General Practice Setting in Crete, Greece

INTRODUCTION

Loneliness is often associated with behavioral, psychological, social, and mental and physical health aspects, while the relationship between trust and loneliness is still challenging in terms of research. The present study aimed to investigate to what extent loneliness and trust interact and if there is any association between loneliness and routine events or behaviors that affect overall well-being.

METHODS

This cross-sectional sample of 120 participants, aged between 40 and 75 years, was collected from an urban Primary Health Care Unit, between May and July 2023, in a consecutive manner, after criteria application. The University of California, Los Angeles (UCLA) Loneliness Scale (Version 3) and the Personal Trust and Connections Scale (PerTC) were completed. Hierarchical multiple linear regression analysis in steps and multiple logistic regression analysis were performed.

RESULTS

The mean age of the participants was 59.8 years and the majority were females (73.3%). Only 10.8% were found to have no Behavioral Risk Factors (BRFs). A higher sense of loneliness was associated with being widowed/unmarried/divorced (unstandardized β=-4.10, p=0.045), not having children (β=-2.80, p=0.038), having more BRFs (β=2.03, p=0.032), or being in contact with fewer friends (β=-0.56, p<0.001). A higher sense of loneliness was related to lower levels of trust (β=-1.29, p=0.032). Lower odds of demonstrating high levels of loneliness were found among married individuals (odds ratio (OR): 0.38; 95% confidence interval (CI) 0.15, 0.95; p=0.039) and those who reported six or more routine contacts or meetings with friends (OR: 0.31; 95% CI 0.13, 0.74; p=0.008). A lower score on the total PerTC scale was related to higher odds of increased loneliness (OR: 2.78; 95%CI 1.01, 7.62; p=0.048).

CONCLUSION

Being married and coming in contact or meeting with more friends was associated with lower odds of reporting high feelings of loneliness, while lower trust was correlated with increased odds of loneliness. Also, persons with more BRFs were found to have a higher loneliness score. Given their inverse correlation, tools that measure levels of loneliness and trust, like the UCLA and PerTC scales, may be used within primary care consultation to offer new insights on health risk behaviors and their possible synergistic influences.

Association between Levels of Loneliness, Laboratory Measurements, and Behavioral Aspects in a Primary Care Setting in Crete, Greece

This paper examines potential associations of loneliness with laboratory data and specific psychosocial and behavioral attitudes. The sample collection took place in an urban Primary Health Care unit between May and July 2023, consecutively, and once exclusion criteria were implemented. Participants were aged between 40 and 75 years. Routine laboratory test results upon study initiation and six months before were used. The University of California, Los Angeles (UCLA), Loneliness Scale (Version 3), blood glucose, serum lipids, Fibrosis-4 index, and Creatinine Clearance (CrCl) were assessed through hierarchical multiple logistic regression analysis. Based on full model (3rd) analysis, those who were engaged in an individual sport or activity or had contacts with more friends presented significantly lower odds for increased loneliness levels (odds ratio (OR): 0.28 [95% confidence interval (CI) 0.09-0.91], p = 0.034 and OR: 0.76 [95%CI 0.66-0.88], p < 0.001, respectively). The consumption of alcohol was associated with increased loneliness (OR: 5.55 [95%CI 1.42-21.63], p = 0.014). Elevated triglyceride levels were linked with moderate or no loneliness (OR: 0.20 [95%CI 0.05-0.83], p = 0.026), while an increased LDL/HDL atherosclerotic index was related to increased subjective loneliness (OR: 4.50 [95%CI 1.12-18.13], p = 0.035). The need for holistic approaches-involving primary care personnel-in understanding and addressing loneliness, recognizing its multifaceted nature as well as the diverse factors that contribute to this issue, is considered challenging.

Exploring the Use of Socially Assistive Robot Among Socially Isolated Korean American Older Adults

This pilot study explored whether a socially assistive robot (SAR) would have positive effects on Korean American immigrant older adults' health behaviors and emotional well-being and whether the older adults would be receptive to the SAR. A total of 30 participants (age 65+) in a large metropolitan area participated in the study, and each participant was provided a SAR named Hyodol for 4 months and interacted with it in ways that they saw appropriate. We used one-group pre- and post-test design to assess changes between baseline and follow-up in medication adherence, depressive symptoms, loneliness, and disability. Additionally, we employed in-depth qualitative interviews to explore participants' perceptions about the SAR. At post-test, participants showed improved medication adherence, reduced depressive symptoms, and a slightly and statistically nonsignificant decrease in loneliness scores. Qualitative data suggested high adoptability of this particular SAR among the participants.

Association of loneliness with suicide risk and depression in individuals with schizophrenia: moderating effects of self-esteem and perceived support from families and friends

Loneliness is prevalent among individuals with mental illnesses. This cross-sectional survey study examined the moderating effects of self-esteem and perceived support from families and friends on the association of loneliness with suicide risk and depression in individuals with schizophrenia. In total, 300 participants (267 with schizophrenia and 33 with schizoaffective disorder) completed the University of California, Los Angeles, Loneliness Scale (Version 3); suicide module of the Mini International Neuropsychiatric Interview; Center for Epidemiologic Studies Depression Scale; Family and Friend Adaptability, Partnership, Growth, Affection, and Resolve Index; and Rosenberg Self-Esteem Scale. Moderation analysis was performed to examine the moderating effects of self-esteem and perceived support from families and friends on the association of loneliness with suicide risk and depression. The results found that self-esteem was significantly associated with a reduced magnitude of depression in participants with loneliness. In addition, perceived support from friends was significantly associated with a reduced magnitude of suicide risk in participants with loneliness. Our findings indicate the importance of intervention programs that strengthen support from friends and self-esteem in reducing suicide risk and depression among lonely individuals with schizophrenia.

A systematic review evaluating loneliness assessment instruments in older adults

Introduction and objectives

The experiences and changes that come along with old age may lead to a feeling of loneliness, usually followed by negative physical and mental manifestations. In this systematic review, we evaluated the existing tools to assess loneliness in older adults.

Methods

We performed a literature search in the Web of Science, Medline, and PsycINFO, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. After, we examined the psychometric properties of the instruments with a focus on reliability, validity, and main conclusions.

Results

We included 27 articles published between 1996 and 2021.

Conclusion

To date, there are few instruments to assess loneliness in older adults. In general, they present adequate psychometric properties, although it is true that some scales show somewhat low levels of reliability and validity.

Use of Exploratory Graph Analysis in Inspecting the Dimensionality of the Revised University of California Los Angeles (R-UCLA) Loneliness Scale Among Older Adults

Exploratory graph analysis (EGA) based on network theory has been introduced as a highly reliable and effective method to assess scales' dimensionality. We estimated the dimensional network structure of the Revised University of California Los Angeles Loneliness Scale using EGA among a cross-sectional cohort of Korean older adults living alone (N = 1,041). We also evaluated the stability of estimates using a bootstrap version of EGA (bootEGA) and verified the overall fit structure using confirmatory factor analysis (CFA). EGA revealed a two-dimensional structure of the scale initially. The bootEGA result revealed that Item 4 ("I do not feel alone") did not sufficiently load on any dimension, and Item 20 ("There are people I can turn to") was replicated in two or more dimensions. Removing these items resulted in better stability of the dimensions, leading to excellent structural consistency. CFA confirmed a satisfactory fit of the improved structure.
