Validity of the de Jong Gierveld Loneliness Scale in Spanish older population: competitive structural models and item response theory

Effectiveness and cost-effectiveness of a home-based functional exercise programme for community-dwelling frail older adults, ACTIVE-AGE@home, provided by professionals and volunteers: protocol of a pragmatic randomised controlled trial

Between 2020 and 2050, the world's population aged 80 years and over will triple, drastically increasing the prevalence of frailty and associated healthcare costs. Multimodal exercise programmes have proven to be an ideal countermeasure for frailty, but the current Flemish standard of care does not include them. The purpose of this study is to investigate the effect of the home-based exercise programme for frail community-dwelling older adults (>70 years), ACTIVE-AGE@home, on frailty-associated outcomes, when delivered by professionals or volunteers, as well as its cost-effectiveness. A pragmatic randomised controlled trial will be conducted. Participants will be randomised into three parallel groups using permuted block randomisation. There will be two intervention groups: in one group, the intervention is delivered by professionals with a bachelor or masters' degree in physiotherapy, occupational therapy and/or physical education, and in the other by trained volunteers. Both groups will be compared with a control group receiving usual care. Participants (n=195) are community-dwelling physically frail older adults (>70 years), as defined by Fried et al. (2001). The intervention is a 24 week programme that consists of three 1 hour visits per week and contains aerobic, strength, balance, flexibility, coordination and dual tasking exercises, accompanied by goal-setting and motivational interviewing. The Timed Chair Stand (TCS) test is the primary outcome. Functional ability, cognition, loneliness, self-management, health-related quality of life, healthcare utilisation and meaningful activities will be measured in all groups at 0, 24 and 48 weeks. Time and expenses invested by professionals or volunteers will be kept in diaries for trial and model-based cost-effectiveness analyses, expressed in incremental cost per QALY (quality-adjusted life year). The model will be designed to associate the frailty at the end of follow-up with further expected healthcare expenses beyond the duration of the trial. Statistical analysis will be blinded to group allocation, and outcome assessors will be blinded to the maximal extent possible. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Medical Ethics Committee of UZ Brussel (O.G. 016), Peer reflection group Biomedical Ethics, Laarbeeklaan 101, 1090 Brussels. Results will be disseminated in publications and other relevant platforms. This study was registered at Clinicaltrials.gov on 6 July 2023 and posted on 14 July 2023 after National Library of Medicine quality control review.

Understanding Loneliness in an Aging Population of San Vito de Coto Brus, Costa Rica

Introduction: As trends in life expectancy continue to improve, the burden of loneliness in geriatric populations on a global scale is increasing. With advancing age comes an increase in the number of life events that can perpetuate a state of loneliness such as losing a life partner, dwindling social networks, and deteriorating health conditions. This burden can manifest in a variety of mental and physical consequences. While loneliness has been studied in a few communities around the world, there is a need to study loneliness in the context of Latin American communities in Central America, including Costa Rica. The aim of the present study is to assess the prevalence and associated factors of social and emotional loneliness (SEL) in a sample of elderly patients in the canton of Coto Brus, Costa Rica. Methods: A cross‑sectional study was conducted that sampled 63 adults aged 65 years or above in the canton of Coto Brus. Investigators conducted face‑to‑face interviews in Spanish with the aid of translators. The primary instruments used for the present study were a content‑validated version of the 11‑item De Jong Gierveld Loneliness Scale and socio‑demographic questions that included age, sex, address, civil status, and level of education. Results: A high degree of SEL was found, with 60.3% of participants noting at least a moderate degree of loneliness, with the average score being 3.33 on the 11‑point scale. When SEL was broken up into its respective subscores, the average score for social loneliness (SL) was found to be 0.67 on the 5‑point scale, and the average score for emotional loneliness (EL) was found to be 2.67 on the 6‑point scale. There was also evidence that supports both level of education and marital status serving as protective factors in the development of SEL. Discussion: These results could indicate a stronger association of loneliness being linked to missing a life partner compared with loneliness being linked to having smaller social networks. Given the associations that were found in this preliminary study, it is pivotal to explore loneliness in this community with a larger sample size-potentially through the integration of the country's Equipos Básicos de Atención Integral de Salud (EBAIS) healthcare system. It is also crucial to expand the study to explore any associations between loneliness and comorbid mental and physical health conditions.

Impact of a peer-support programme to improve loneliness and social isolation due to COVID-19: does adding a secure, user friendly video-conference solution work better than telephone support alone? Protocol for a three-arm randomised clinical trial

INTRODUCTION

The COVID-19 pandemic has forced the implementation of physical distancing and self-isolation strategies worldwide. However, these measures have significant potential to increase social isolation and loneliness. Among older people, loneliness has increased from 40% to 70% during COVID-19. Previous research indicates loneliness is strongly associated with increased mortality. Thus, strategies to mitigate the unintended consequences of social isolation and loneliness are urgently needed. Following the Obesity-Related Behavioural Intervention Trials model for complex behavioural interventions, we describe a protocol for a three-arm randomised clinical trial to reduce social isolation and loneliness.

METHODS AND ANALYSIS

A multicentre, outcome assessor blinded, three-arm randomised controlled trial comparing 12 weeks of: (1) the HOspitals WoRking in Unity ('HOW R U?') weekly volunteer-peer support telephone intervention; (2) 'HOW R U?' deliver using a video-conferencing solution and (3) a standard care group. The study will follow Consolidated Standard of Reporting Trials guidelines.We will recruit 24-26 volunteers who will receive a previously tested half day lay-training session that emphasises a strength-based approach and safety procedures. We will recruit 141 participants ≥70 years of age discharged from two participating emergency departments or referred from hospital family medicine, geriatric or geriatric psychiatry clinics. Eligible participants will have probable baseline loneliness (score ≥2 on the de Jong six-item loneliness scale). We will measure change in loneliness, social isolation (Lubben social network scale), mood (Geriatric Depression Score) and quality of life (EQ-5D-5L) at 12-14 weeks postintervention initiation and again at 24-26 weeks.

ETHICS AND DISSEMINATION

Approval has been granted by the participating research ethics boards. Participants randomised to standard care will be offered their choice of telephone or video-conferencing interventions after 12 weeks. Results will be disseminated through journal publications, conference presentations, social media and through the International Federation of Emergency Medicine.

Emotional and social loneliness and their unique links with social isolation, depression and anxiety

BACKGROUND

Loneliness and social isolation are known to be associated with depression, general anxiety, and social anxiety. However, knowledge on the overlapping and unique features of these relationships, while differentiating between social loneliness (perceived absence of an acceptable social network) and emotional loneliness (perceived absence of close connections), is lacking.

METHODS

We constructed a network analysis to examine the relationships between self-reported social loneliness, emotional loneliness, social isolation, depression, general anxiety and social anxiety in a large sample of university students (N = 7314, 67.4 % female, range 16.3-75.8 years, M_age = 23.9, SD_age = 5.7). Hierarchical regression analyses were used to examine whether depression, general anxiety and social anxiety moderated the relationship between social isolation and loneliness types. As comorbidity between anxiety and depression is high, the role of anxiety as a moderator in the relationship between depression and loneliness types was also examined.

RESULTS

The network analysis showed that social loneliness was most strongly explained by social isolation, whereas emotional loneliness was most strongly explained by social anxiety and depression. General anxiety was solely related to loneliness through depression. The regression analyses showed that general and social anxiety and depression did not moderate the relationship between social isolation and loneliness types.

LIMITATIONS

Differences found between loneliness types may be influenced by a methodological artifact of the DJGLS.

CONCLUSIONS

These findings highlight the importance of social anxiety over general anxiety in relation to loneliness. Also, it showed unique relationships for social- and emotional loneliness with psycho-social variables, which has important implications for research- and clinical settings.

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.

Older adults' community participation, physical activity, and social interactions during and following COVID-19 restrictions in Australia: a mixed methods approach

BACKGROUND

With the increasing age of the global population, key components of healthy ageing including community, physical, and social participation continue to gain traction. However, management of the COVID-19 pandemic aimed to protect older adults and reduce the spread of the virus, this restricted community participation and reduced the opportunities for social interaction.

METHODS

This mixed methods study investigates community dwelling older adults' community participation; physical activity and social interaction prior to, during, and following the COVID-19 lockdown in Adelaide, Australia. Twenty-six community dwelling older adults were monitored over three time-points between November 2018 and October 2020, with Global Positioning Systems, accelerometry and self-reported diaries. In addition, nineteen participants completed semi-structured interviews.

RESULTS

Community participation varied across the three time points, with significant reduction in the number of trips taken out-of-home (p = 0.021), social interactions (p = 0.001) and sleep quality (p = 0.008) during restrictions. Five themes were identified to explain personal experiences of community participation during restrictions: (1) Reframing of meaning, (2) Redefining to maintain activities, (3) Revision of risk, (4) Reflection and renewal and (5) Future planning.

CONCLUSION

During COVID-19 the physical and social activities of community dwelling older adults changed. Services that support older adults to adapt their activities   , considering their capacities and preferences, to facilitate community participation are required.

Validation of the De Jong Gierveld Loneliness Scale in Peruvian old adults: a study based on SEM and IRT multidimensional models

Loneliness is a public health problem. Its assessment is important to identify older adults who experience greater loneliness and appropriate interventions can be carried out. The De Jong Gierveld Solitude Scale (DJGLS) is one of the most widely used, at least in the European context, to measure loneliness. Although the Spanish version of the DJGLS has shown reliability and validity in Spanish samples of older adults, there is no evidence of adequacy in the Latin American context. Therefore, this study aims to evaluate the psychometric properties of the DJGLS in Peruvian older adults. Specifically, factorial validity, internal consistency and criterion-related validity were studied, based on a double analytical perspective: Classical Test Theory (SEM models) and Item Response Theory. The participants were 235 Peruvian older adults with ages ranging from 61 to 91 years old (Mean = 72.69, SD = 6.68) that assisted to Centers for the Elderly in the city of Trujillo, Peru. Together with the DJGLS, information from the three-item UCLA loneliness scale, Satisfaction with Life Scale, Brief Resilient Coping Scale and the Patient Health Questionnarie-2 was also gathered. The results support a one-dimensional structure of the DJGLS but with the presence of method effects associated to the negatively worded items. Additionally, the IRT multidimensional model applied also indicated the presence of a second dimension related to these negative items. Finally, other evidences of reliability and validity were adequate. In summary, the DJGLS may be considered a reliable and valid instrument to be used in the Peruvian (older adults) context.

Multicountry study protocol of COCOON: COntinuing Care in COVID-19 Outbreak global survey of New, expectant, and bereaved parent experiences

INTRODUCTION

Globally, the COVID-19 pandemic has significantly disrupted the provision of healthcare and efficiency of healthcare systems and is likely to have profound implications for pregnant and postpartum women and their families including those who experience the tragedy of stillbirth or neonatal death. This study aims to understand the psychosocial impact of COVID-19 and the experiences of parents who have accessed maternity, neonatal and bereavement care services during this time.

METHODS AND ANALYSIS

An international, cross-sectional, online and/or telephone-based/face-to-face survey is being administered across 15 countries and available in 11 languages. New, expectant and bereaved parents during the COVID-19 pandemic will be recruited. Validated psychometric scales will be used to measure psychosocial well-being. Data will be analysed descriptively and by assessing multivariable associations of the outcomes with explanatory factors. In seven of these countries, bereaved parents will be recruited to a nested, qualitative interview study. The data will be analysed using a grounded theory analysis (for each country) and thematic framework analysis (for intercountry comparison) to gain further insights into their experiences.

ETHICS AND DISSEMINATION

Ethics approval for the multicountry online survey, COCOON, has been granted by the Mater Misericordiae Human Research Ethics Committee in Australia (reference number: AM/MML/63526). Ethics approval for the nested qualitative interview study, PUDDLES, has been granted by the King's College London Biomedical & Health Sciences, Dentistry, Medicine and Natural & Mathematical Sciences Research Ethics Subcommittee (reference number: HR-19/20-19455) in the UK. Local ethics committee approvals were granted in participating countries where required. Results of the study will be published in international peer-reviewed journals and through parent support organisations. Findings will contribute to our understanding of delivering maternity care services, particularly bereavement care, in high-income, lower middle-income and low-income countries during this or future health crises.

Older adults' mentioned practices for coping with loneliness

In recent years, loneliness has been receiving increasing attention, yet there remains a lot to learn about how older adults cope with loneliness. In this study, the practices older adults consider for coping with loneliness and the relationship between various types of coping practices, loneliness, and personal resources are examined. Several hypotheses about the relationship between social and emotional loneliness, personal resources, and mentioning coping practices are formulated. Data was collected in Gipuzkoa (Basque Country, Spain) through structured interviews using a telephone survey among a representative sample of older adults aged 55 and over (N = 894). Results show that lonely and non-lonely respondents alike consider a few coping practices and prefer active and individual coping practices over social and passive ones for coping with loneliness. Experiencing emotional loneliness is related to mentioning more individual and active coping practices. Social coping practices were considered less often by respondents who experienced better self-rated health and more often by respondents with vision loss, a higher educational level and higher quality of life. In conclusion, while older adults differ in coping efforts they mention, these differences are only explained to a small extent by their experience of loneliness and available resources. For future research and practice development, a deeper understanding of the process of coping with loneliness is needed.

Support after COVID-19 study: a mixed-methods cross-sectional study to develop recommendations for practice

Objectives of study stage 1 were to: explore people's experiences of illness due to COVID-19 while feeling socially isolated or socially isolating; identify perceptions of what would support recovery; and synthesise insights into recommendations for supporting people after COVID-19. Study stage 2 objectives were to engage stakeholders in evaluating these recommendations and analyse likely influences on access to the support identified.

DESIGN

A two-stage, multimethod cross-sectional study was conducted from a postpositivist perspective. Stage 1 included an international online survey of people's experiences of illness, particularly COVID-19, in isolation (n=675 full responses). Stage 2 involved a further online survey (n=43), two tweetchats treated as large online focus groups (n=60 and n=27 people tweeting), two smaller focus groups (both n=4) and one interview (both using MS teams).

SETTING

Stage 1 had an international emphasis, although 87% of respondents were living in the UK. Stage 2 focused on the UK.

PARTICIPANTS

Anyone aged 18+ and able to complete a survey in English could participate. Stage 2 included health professionals, advocates and people with lived experience.

MAIN OUTCOME MEASURES

Descriptive data and response categories derived from open responses to the survey and the qualitative data.

RESULTS

Of those responding fully to stage 1 (mean age 44 years); 130 (19%) had experienced COVID-19 in isolation; 45 had recovered, taking a mean of 5.3 (range 1-54) weeks. 85 did not feel they had recovered; fatigue and varied 'other' symptoms were most prevalent and also had most substantial negative impacts. Our draft recommendations were highly supported by respondents to stage 2 and refined to produce final recommendations.

CONCLUSIONS

Recommendations support access to progressive intensity and specialism of support, addressing access barriers that might inadvertently increase health inequalities. Multidisciplinary collaboration and learning are crucial, including the person with COVID-19 and/or Long Covid in the planning and decision making throughout.

Determinants of Subjective Loneliness and Quality of Life among Community-Dwelling Older Adults in Gorgan, Iran

The purpose of this study was to identify the determinants of, and relationship between, subjective loneliness, general health and quality of life (QoL) among lonely community-dwelling older adults. A cross-sectional study was carried out among a sample of lonely (i.e. live alone without any assistance) older adults living in Gorgan city, Iran. The older adults were invited through a census sampling technique to complete six questionnaires, namely a 20-item UCLA loneliness scale, a six-item Lubben Social Network Scale, a 12-item Multidimensional Scale of Perceived Social Support, a 17-item Self-care Ability Scale for the Elderly (SASE), a General Health Questionnaire-12, and a Control, Autonomy, Self-Realization and Pleasure (CASP-19) questionnaire. Hierarchical multiple linear regressions were done with subjective loneliness and QoL as outcome variables. In total, 213 (91% females) lonely older adults (mean age: 68.2 ± 6.2) participated. Hierarchical multiple linear regressions yield socio-demographic characteristics (p < 0.001), predictor group 1 (p < 0.001), predictor group 2 (p < 0.001) explained 12.5, 13.5 and 46.6% of the observed variance in loneliness, respectively. Moreover, socio-demographic characteristics (p < 0.001), predictor group 1 (p < 0.001), predictor group 2 (p < 0.001) and feeling of loneliness (p < 0.001) accounted for 16.9, 21.1, 48.6 and 55.3% of the observed variance in quality of life, respectively. Both subjective loneliness and QoL were moderate in our sample. We suggest the presence of a probable causal inference between subjective loneliness, general health, and QoL; implying the need of population strategies for correcting subjective loneliness for its own sake as well as to help have an improved general health and QoL among older adults. Beside several non-modifiable factors (such as age, ethnic groups), we suggest that corrective measures should be based on social support and networking, self-care behavior, leisure activities, adapted for age, literacy and racial specifications. Given its population health relevance, there should be increased research and intervention on loneliness among older adults.

Psychometrics of Persian version of the 11 items De Jong Gierveld loneliness scale among an Iranian older adults population

Background

Older adults duo to circumstances of aging such as relationship losses, medical morbidities, and functional declines, are prone to social isolation and loneliness more than any other age group. Furthermore, with The recent outbreak of the COVID-19 pandemic and the need to quarantine, the possibility of feelings of loneliness, especially in older adults, became an important nursing priority. Therefore, it is important to quickly identify loneliness and respond appropriately to prevent, reduce, or treat it. The aim of this study was to translate the De Jong Gierveld loneliness scale into Persian for older adults.

Methods

The sample was 400 adults aged 65 and older with a mean age of 71.32 (SD= ± 6.09) years. Recruitment and data collection was done via online methods. The original scale was translated into Persian using the World Health Organization (WHO) protocol of forward-backward translation technique. Face validity and content validity; was followed by exploratory and confirmatory factor analysis. Lastly, reliability was assessed using the Average Inter-Item Correlation, Cronbach’s alpha, and McDonald’s Omega.

Results

The results showed that the Persian version of the loneliness scale had two factors namely social loneliness (5 items) and emotional loneliness (3 items) and the combined score explained 45.66% of the total variance of this scale. In addition, all goodness of fit indices confirmed a two factors model fit and all of the reliability indices were excellent.

Conclusions

The Persian version of the loneliness scale is useful and suitable for detecting social loneliness and emotional loneliness in older Iranian adults.

Perceived Loneliness and Severe Sleep Disorders in Adult Women during the Covid-19 Quarantine: A Cross-Sectional Study in Colombia

Background:

Quarantine is a measure to control COVID-19 spread, resulting in an increased perception of loneliness. In turn, sleep disorders (SD) may be more frequently reported in uncertain circumstances.

Objectives:

To identify the association between loneliness and severe SD, in women quarantined due to the COVID-19 pandemic.

Methods:

A cross-sectional study carried out in women, between 40 and 79 years and living in Colombia. The women were invited through social network to complete 5 digital instruments: de Jong Gierveld Loneliness Scale, Menopause Rating Scale, Fear of COVID-19 Five-item Version, Coronavirus Anxiety Scale, and Francis Religion Scale. Bivariate analysis and adjusted logistic regression between loneliness and SD were performed.

Results:

1133 women participated, half of them under 50 years old. 43.1% had emotional loneliness, 39.9% social loneliness and 43.3% general loneliness. SD were identified in 6 out of 10 women, those with mild SD presented an OR of 1.84, 1.85, and 1.64, for emotional, social and general loneliness, respectively. Loneliness was associated twice with moderate SD, and more than twice with severe SD. Very severe SD reached OR:5.81 for emotional loneliness, OR:4.38 social loneliness and OR:4.02 general loneliness. In the presence of religiosity, fear and anxiety due to COVID-19, statistical significance was retained for associations, except intense SD with general loneliness.

Conclusions:

SD were significantly associated with loneliness in our study population. It is important to assess sleep quality and perception of loneliness in middle-aged women, especially during periods of quarantine due to a pandemic to avoid health implications.

Online assessment of the perception of loneliness and associated factors in Colombian climacteric women during the COVID-19 pandemic: A cross-sectional study

Background: The coronavirus disease 2019 (COVID-19) pandemic has generated changes due to confinement, this measure can increase the perception of loneliness. The objective was to estimate the frequencies of emotional, social and general loneliness and their association with fear and anxiety with COVID-19, religiosity and severe deterioration of quality of life in middle-aged women. Methods: A cross-sectional study in Colombian women (40-59 y, n=984) surveyed with an electronic form that included sociodemographic characteristics and validated measures (Menopause Rating Scale, de Jong Gierveld Loneliness Scale, fear of COVID-19 scale, Coronavirus Anxiety Scale and Francis Scale for Religiosity). Associations of emotional, social and general loneliness (dependent variables) with severe somatic, psychological, urogenital and quality of life deterioration, as well as with high religiosity, anxiety and high fear of COVID-19 (independent variables), were estimated. Results: The median age was 47 years old, and 39.2% [95% CI: 36.2-42.3] postmenopausal. Severe deterioration in somatic, psychological, urogenital domains and quality of life in women with emotional, social and general loneliness was found (P <0.001). In adjusted models, high fear of COVID-19, severe deterioration of psychological and urogenital domains and quality of life were associated with emotional, social and general loneliness. Anxiety with COVID-19, somatic domain and high religiosity were not associated with loneliness. Conclusion: Emotional, social and general loneliness were identified in 4/10 middle-aged Colombian women surveyed, and the associated factors were high fear of COVID-19, severe deterioration of quality of life and psychological and urogenital domains. Professionals who care for climacteric women should explore the perception of loneliness when assessing menopausal symptoms.

Community participation of community dwelling older adults: a cross-sectional study

BACKGROUND

With the advancing age of the population, and increasing demands on healthcare services, community participation has become an important consideration for healthy ageing. Low levels of community participation have been linked to increased mortality and social isolation. The extent to which community participation has been measured objectively in older adults remains scarce. This study aims to describe where and how older adults participate in the community and determine the feasibility of measurement methods for community participation.

METHODS

This observational cross-sectional study obtained data from 46 community dwelling older adults. A combination of Global Positioning Systems (GPS), accelerometry, and self-reported diaries were used over a 7-day monitoring period. Feasibility of methods were determined by calculating the loss of GPS data, questionnaires, and comparison of self-reported locations with GPS co-ordinates. Relationships between community participation, physical activity, social interactions, health related quality of life, sleep quality and loneliness were explored.

RESULTS

Older adults took a median (IQR) of 15 (9.25-18.75) trips out of home over the 7-day monitoring period, most frequently visiting commercial and recreational locations. In-home activities were mainly sedentary in nature, with out of home activities dependent on location type. Self-reported and GPS measures of trips out of home and the locations visited were significantly correlated (self-report 15.7 (5.6) GPS 14.4 (5.8) (r = 0.94)). Significant correlations between both the number of trips taken from home, with social interactions (r = 0.62) and the minutes of moderate to vigorous physical activity (MVPA) (r = 0.43) were observed. Daily MVPA was higher in participants who visited local walk/greenspaces (r = 0.48).

CONCLUSION

Participants performed more activities with social interactions out of home and visited commercial locations most frequently. The combination of GPS, accelerometry and self-report methods provided a detailed picture of community participation for older adults. Further research is required with older adults of varying health status to generalise the relationships between community participation, location and physical activity.

TRIAL REGISTRATION

Ethical approval was gained from the Flinders University Social and Behavioural Research Ethics Committee (protocol no. 8176).

Development and validation of a 6-item Revised UCLA Loneliness Scale (RULS-6) using Rasch analysis

OBJECTIVE

The UCLA Loneliness Scale, containing 20 items, is one of the commonly used loneliness scales. Some shorter versions have been developed using factor analysis. The study aimed to shorten the UCLA Loneliness Scale using Rasch and factor analysis methods and test the psychometric properties of the new scale.

METHODS

The full sample of the study included 719 respondents, divided into three subsamples (205, 324, and 190 for samples 1-3, respectively). The original, 20-item Revised UCLA Loneliness Scale (R-ULS) was shortened using 205 students (sample 1); the shortened scale was then validated for construct and concurrent validity with 324 students (sample 2) and 190 clinical participants (sample 3). Confirmatory factor analysis and Rasch analysis were used for construct validity. Convergent, discriminant, and concurrent validity were assessed by exploring the correlation with other psychological measurements.

RESULTS

In sample 1, the R-ULS was shortened to a 6-item scale (RULS-6) that fits the Rasch model. The RULS-6 met the criteria of unidimensionality and local independence without differential item functioning due to age and sex, and good targeting the clinical sample. Person Separation Index (PSI) reflected that reliability from the Rasch perspective was acceptable. However, collapsing categories 2 (sometime) and 3 (rarely) may be required in a clinical sample. When tested in samples 2 and 3, the RULS-6 fits the Rasch measurement model. Convergent and discriminant validity were demonstrated with interpersonal problems and attachment scales. As expected, a positive correlation was found between RULS-6 and anxiety, depression subscale, interpersonal difficulties, and somatization subscales denoting concurrent validity. Cronbach's alpha of the RULS-6 was good (.83).

CONCLUSION

Using Rasch analysis, the proposed RULS-6 constituted a 70% reduction of the number of original items, yet preserved the psychometric properties in independent samples of students and psychiatric outpatients. Statement of contribution What is already known on this subject? The UCLA Loneliness Scale is a common instrument used to gauge loneliness levels. The 20-item revised scale (R-ULS) has acceptable psychometric properties but its construct varies. Due to the length of the questionnaire, administration of R-ULS is not always practical. Short versions vary in items and were developed with classic test theory (e.g., factor analysis). Rasch analysis - providing more accuracy based on measurement theory - could be used instead. What does this study add? Using a Rasch analysis approach, a 6-item scale of loneliness (RULS-6) was created. The RULS-6 was tested in student and clinical samples, meeting Rasch measurement model criteria. The RULS-6 showed promising psychometrics to be used in both non-clinical and clinical samples.

Longitudinal Examination of Emotional Functioning in Older Adults After Spousal Bereavement

Objectives

This study examined trajectories of emotional functioning in three domains (depressive symptoms, emotional, and social loneliness) for individuals who experienced spousal bereavement and investigated cross-domain adaptation. We hypothesized that emotional difficulties after bereavement would be more detectable in emotional loneliness than depressive symptoms or social loneliness.

Methods

Using latent class growth analysis, we modeled changes in depressive symptoms, emotional loneliness, and social loneliness from 12 years pre- to 12 years post-bereavement on data from 686 older adults to identify trajectories indicating adaptive and maladaptive functioning in each domain.

Results

Most participants reported depressive symptoms below the clinically relevant threshold by showing a resilient (15.5%) or a slightly elevated (53.5%) trajectory post-bereavement. One third (31%) reported clinically relevant depressive symptoms. More than half of the sample reported emotional loneliness post-bereavement, varying form prolonged (17%), increasing and prolonged (28.3%), and chronically high (8.9%) levels. Remaining participants displayed resilience (13.5%) or recovery (32.3%). Social loneliness showed four trajectories: very low and resilient (43.3%), low and resilient (27.5%), increasing (20.2%), and chronically high (9%) levels. One third of participants maintained adaptive, whereas 12% displayed maladaptive, functioning across all domains post-bereavement.

Discussion

An increase in emotional loneliness was the most commonly observed change after spousal bereavement. This highlights the central role of emotional loneliness in depression after bereavement.
