Validation of the University of California, Los Angeles Loneliness Scale (version 3) in Spanish older population: An application of exploratory structural equation modelling

Understanding the Effect of Loneliness on Quality of Life in Older Adults from Longitudinal Approaches

Aim: To study the longitudinal relationship between loneliness and quality of life (QoL) in adults to identify key mechanisms to better design future psychosocial interventions. Method: 13,222 participants from three consecutive waves of the Survey of Health, Ageing, and Retirement in Europe (SHARE), aged 65 or older, 56.3% women. They were analyzed using cross-lagged panel model (CLPM), random intercept cross-lagged panel model (RI-CLPM), and multi-group models disaggregated by gender. Results: The RI-CLPM provided a better fit than the CLPM. Both models showed the stability of QoL and loneliness. All autoregressive paths were significant, and a negative association between concurrent QoL and loneliness was observed across all waves. The CLPM supported a reciprocal relationship, while the RI-CLPM only confirmed the effects of loneliness on QoL. Women reported higher levels of loneliness and poorer QoL, but no gender differences were identified in the longitudinal association. Conclusions: Addressing loneliness in early stages could be a better preventive measure to promote quality of life in both genders.

Rural-urban differences in older adults' life satisfaction and its determining factors

Although determinants of life satisfaction in older adults have been well documented, research has to date failed to fully address the experience of older adults living in places with different levels of urbanization. Furthermore, there are conflictive findings regarding the type of residence environment that offers the greatest benefits for the wellbeing of older adults. Our study proposes an integrative research model to determine the nature of the relationships between loneliness, self-esteem and life satisfaction, with a particular focus on the living environment (rural-urban) of the older adults. Using a cross-sectional survey design volunteers (aged 60+) from rural (n = 198) and urban (n = 198) in Galicia (Spain) completed a questionnaire. Structural Equation Modelling (SEM) was used to test the relationships between loneliness, self-esteem and life satisfaction and multigroup analysis was performed to analyse the existence of differences in the relationships based on the area of residence of older adults. We found that higher levels of loneliness were a significant predictor of reduced life satisfaction and reduced self-esteem. Self-esteem not only increases life satisfaction, but also reduces the negative impact loneliness may have on it. Where the older adults lived had a significant effect on the relationships between loneliness, self-esteem and life satisfaction. The relationships were stronger for older adults living in urban areas. Differentiated policy initiatives should be considered, depending on the area of residence in order to increase the life satisfaction of older adults.

Loneliness and Subjective Wellbeing During the Covid-19 Pandemic: A Systematic Review

To prevent the transmission of COVID-19, unprecedented measures were implemented, such as community lockdowns. With limited social interactions, the problem of loneliness might have worsened. As loneliness is thought to have a detrimental effect on subjective wellbeing (SWB), the present systematic review aims to better investigate and summarize the existing evidence about the association of loneliness and SWB during the COVID-19 pandemic. A total of 18 articles were included. In all studies, independently of the component of wellbeing assessed or of the instrument used, a negative association between loneliness and SWB was found. The results show an increase in loneliness during times of restrictions on social contacts, with a subsequent association with lower SWB, and underscore the need for developing specific interventions to tackle loneliness and for promoting alternative forms of social interaction if further physical distancing measures are needed. However, the literature had several limitations, since most of the studies followed cross-sectional and descriptive methodologies.

Changes in mental health symptoms and sociocultural factors across the COVID-19 pandemic in mothers of Mexican descent

Latinos have been disproportionately affected by the COVID-19 pandemic in the US. Little is known about the lasting effects on mental health, particularly among mothers of young children, who historically report high levels of depression and anxiety. We examined if anxiety and depression symptoms worsened for mothers of Mexican descent across the pandemic and identified the role of sociocultural risk and protective factors on these changes. Mothers of Mexican descent (n = 141) with young children (ages 0-7) were administered surveys on mental health symptoms (anxiety and depression), stress-related sociocultural factors (perceived discrimination) before (pre-pandemic), within 3 months (early pandemic), and 18 months after the COVID-19 stay-at-home order (late pandemic). Another sociocultural factor, acculturative stress, was only measured pre-pandemic while during the later phase of the pandemic mothers reported their levels of loneliness, optimism, and coping styles. Repeated measures (RM) ANOVA demonstrated that depressive and anxiety symptoms as well as perceived discrimination increased from pre to early months of the COVID-19 pandemic and slightly lowered in late-COVID but did not return to pre-COVID levels. Two-way RM ANOVA showed that acculturative stress and perceived discrimination predicted worse mental health trajectories across the pandemic while moderations revealed that optimism buffered against, and avoidant coping increased the adverse effects of sociocultural factors on mental health. The effects of the COVID pandemic on mental health are lingering in mothers of young children; however, optimism may be a protective factor. The results also highlight the damaging effects of external factors, such as discrimination, on maternal mental health during times of crisis.

An exploratory psychometric network analysis of loneliness scales in a sample of older adults

To examine the relationships within and between commonly used measures of loneliness to determine the suitability of the measures in older adults. Further, to determine whether certain items in these measures are more psychometrically robust in terms of capturing different types of loneliness across this population. Data were obtained from 350 older adults via completion of an online survey. Four measures of loneliness were completed. These were the University of California Los Angeles Loneliness Scale 4 (Version 3), the de Jong Gierveld Loneliness Scale, the Social and Emotional Loneliness Scale for Adults (Short Version) and a direct measure of loneliness. Analysis via a regularized partial correlation network and via clique percolation revealed that only the SELSA-S encompassed loneliness relating to deficits in social, family and romantic relationships. The remaining measures tapped mostly into social loneliness alone. The direct measure of loneliness had the strongest connection to the UCLA item-4 and the de Jong Gierveld item-1 exhibited the strongest bridge centrality, being a member of the most clusters. The results indicate that should researchers be interested in assessing loneliness resulting from specific relationships, then the SELSA-S would be the most suitable measure. Whereas the other measures are suitable for assessing loneliness more generally. The results further suggest that the de Jong Gierveld item-1 may be a more suitable direct measure of loneliness than that currently employed as it taps into a greater number of relationships.

What factors explain the changes in major depressive disorder symptoms by age group during the COVID-19 pandemic? A longitudinal study

BACKGROUND

Data collected during the COVID-19 pandemic suggest an increase in major depressive disorder (MDD) among younger adults. The current study aims to assess the association of age groups and MDD risk before and during the COVID-19 pandemic and quantify the effect of potential mediating variables such as loneliness, social support, resilience, and socioeconomic factors.

METHODS

A representative sample of Spanish adults was interviewed before (2019, N = 1880) and during (2020, N = 1103) the COVID-19 pandemic. MDD was assessed using the CIDI, loneliness through the UCLA scale, social support through the OSSS-3, resilience with the 6-BRS, and worsened economic circumstances and unemployment through a single question. Mixed-models were used to study changes in MDD by age group. Regression models were constructed to quantify the association between age and potential mediators, as well as their mediating effect on the association between age group and MDD.

RESULTS

Among the younger age cohorts (18-29 and 30-44 years) the probability of having MDD during the pandemic increased from 0.04 (95 % CI: 0.002-0.09) to 0.25 (0.12-0.39) and from 0.02 (-0.001-0.03) to 0.11 (0.04-0.17), respectively. Some 36.6 % of the association between age and risk of MDD during the pandemic was explained by loneliness (12.0 %), low resilience (10.7 %), and worsened economic situation (13.9 %).

LIMITATIONS

Reliance on self-report data and generalizability of the findings limited to the Spanish population.

CONCLUSIONS

Strategies to decrease the impact of a pandemic on depressive symptoms among young adults should address loneliness, provide tools to improve resilience, and enjoy improved financial support.

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.

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.

Are we measuring loneliness in the same way in men and women in the general population and in the older population? Two studies of measurement equivalence

BACKGROUND

High levels of loneliness are associated with negative health outcomes and there are several different types of interventions targeted at reducing feelings of loneliness. It is therefore important to accurately measure loneliness. A key unresolved debate in the conceptualisation and measurement of loneliness is whether it has a unidimensional or multidimensional structure. The aim of this study was to examine the dimensional structure of the widely used UCLA Loneliness Scale and establish whether this factorial structure is equivalent in men and women.

METHODS AND SAMPLE

Two online UK-based samples were recruited using Prolific. The participants in Study 1 were 492 adults, selected to be nationally representative by age and gender, whilst the participants in Study 2 were 290 older adults aged over 64. In both studies, participants completed the UCLA Loneliness Scale (Version 3) as part of a larger project.

RESULTS

In both studies, the best fitting model was one with three factors corresponding to 'Isolation,' 'Relational Connectedness,' and 'Collective Connectedness.' A unidimensional single factor model was a substantially worse fit in both studies. In both studies, there were no meaningful differences between men and women in any of the three factors, suggesting measurement invariance across genders.

CONCLUSION

These results are consistent with previous research in supporting a multidimensional, three factor structure to the UCLA scale, rather than a unidimensional structure. Further, the measurement invariance across genders suggests that the UCLA scale can be used to compare levels of loneliness across men and women. Overall the results suggest that loneliness has different facets and thus future research should consider treating the UCLA loneliness scale as a multidimensional scale, or using other scales which are designed to measure the different aspects of loneliness.

Validez de la escala de soledad UCLA en cuidadores de pacientes crónicos en Colombia

Introducción: la soledad en cuidadores familiares se presenta como una experiencia frecuente debido a las demandas que implica el cuidado de una persona con enfermedad crónica. Objetivo: determinar la validez facial y de contenido de la UCLA en cuidadores familiares de personas con enfermedad crónica. Método: estudio psicométrico de validación facial y de contenido de la escala UCLA. Para la validación del contenido participaron expertos en el área y los ítems se valoraron en términos de claridad, redundancia y relevancia. El índice Lawshe modificado por Tristán fue el estadístico usado para su análisis. Para la validación facial participaron cuidadores familiares de personas con enfermedad crónica a quienes se les realizó una entrevista cognitiva y se analizaron las áreas de comprensión, recuperación, juicio, adecuación de opciones de respuesta y contenido de la pregunta. Resultados: validez de contenido: 9 de 18 ítems de la escala UCLA presentaron IVC ajustado superior a 0,8. El ítem 8 presentó IVC ajustado de 0,66, lo que requirió análisis y ajuste semántico por parte del comité de validación. Con respecto a la validez facial, a partir del proceso de entrevista cognitiva se evidenció que para todos los ítems el 86 % o más de los participantes reportaron una adecuada comprensión, recuperación, juicio y adecuación de los ítems. Luego del análisis cualitativo de las respuestas, el ítem 7 requirió ajuste semántico. Conclusiones: la escala UCLA cuenta con la validez de contenido y facial aceptable para su uso en cuidadores de personas con enfermedad crónica en Colombia. Se propone una versión del instrumento ajustada semánticamente.

Comparing the Psychometric Properties among Three Versions of the UCLA Loneliness Scale in Individuals with Schizophrenia or Schizoaffective Disorder

The UCLA Loneliness Scale (Version 3; UCLA-LSV3) is widely used for assessing loneliness. Nevertheless, the validity of this scale for assessing loneliness in individuals with schizophrenia or schizoaffective disorder has not been determined. Additionally, studies validating the eight-item and three-item versions of UCLA-LSV3 have not included individuals with severe mental illness; therefore, whether the short versions are comparable to the full 20-item version of UCLA-LSV3 for this population is unclear. The present study examined the unidimensional structure, internal consistency, concurrent validity, and test–retest reliability of the Chinese versions of UCLA-LSV3 (i.e., 20-item, 8-item, and 3-item versions) to determine which version is most appropriate for assessing loneliness in individuals with schizophrenia or schizoaffective disorder in Taiwan. A total of 300 participants (267 with schizophrenia and 33 with schizoaffective disorder) completed the scales, comprising UCLA-LSV3, the Center for Epidemiological Studies Depression Scale (CES-D), the suicidality module of the Kiddie Schedule for Affective Disorders and Schizophrenia–Epidemiological Version (K-SADS-E), and the family and peer Adaptation, Partnership, Growth, Affection, and Resolve (APGAR) index. Construct validity was evaluated through confirmatory factor analysis. The three versions of UCLA-LSV3 were compared with the CES-D, the suicidality module of the K-SADS-E, and the family and peer APGAR index to establish concurrent validity. The results indicated that all three versions of UCLA-LSV3 exhibited acceptable to satisfactory psychometric properties in terms of unidimensional constructs, concurrent validity, and test–retest reliability. The full version of UCLA-LSV3 had the best performance, followed by the eight-item version and the three-item version. Moreover, the three versions had relatively strong associations with each other. Therefore, when deliberating which version of UCLA-LSV3 is the best choice for assessing loneliness in individuals with schizophrenia or schizoaffective disorder, healthcare providers and therapists should consider time availability and practicality.

Psychometric testing of the Brief Sense of Community Scale with older adults in Puerto Rico

The Brief Sense of Community Scale (BSCS) is a well-validated measure of psychological sense of community (PSOC), but it has yet to be tested with Spanish-speaking older adults. The current study uses data from face-to-face interviews with a non-probability sample of 154 community-dwelling older adults in Puerto Rico. We used confirmatory factor analysis (CFA) to test three competing factor structures. We also tested internal consistency reliability and convergent validity. CFA results show the second-order four-factor model was the best fit (χ² (16) = 20.78, p = 0.187; CFI = 0.997, TLI = 0.995, SRMR = 0.026, RMSEA = 0.044, 90% CI [<0.001, 0.092]). The BSCS showed good reliability (α = 0.85) and was correlated in the expected direction with social network size (r = 0.34, p < 0.001) and loneliness (r = -0.27, p < 0.001). These findings indicate that the BSCS comprises the four domains (membership, needs fulfillment, emotional connection, and influence) from the original PSOC theory. These results inform theory development and can aid program planning, policy, and practice with older adults in Puerto Rico.

Psychometric Evaluation of Three Versions of the UCLA Loneliness Scale (Full, Eight-Item, and Three-Item Versions) among Sexual Minority Men in Taiwan

The UCLA Loneliness Scale, with different short versions, is widely used to assess levels of loneliness. However, whether the scale is valid in assessing loneliness among sexual-minority men is unknown. Additionally, it is unclear whether the 8-item and 3-item short versions are comparable to the full 20-item version. The present study compared the validity of the three versions of the UCLA Loneliness Scale (i.e., 20-item, 8-item, and 3-item versions) among gay and bisexual men in Taiwan. The participants comprised 400 gay and bisexual men in Taiwan who completed a cross-sectional online survey, which included the UCLA Loneliness Scale, Center for Epidemiological Studies Depression Scale (CES-D) and State–Trait Anxiety Inventory (STAI). Confirmatory factor analysis was used to evaluate factorial validity. Convergent validity was examined between the three versions of the UCLA Loneliness Scale and the CES-D and STAI. Known-group validity was investigated with participants’ sexual orientation and educational levels. The unidimensional construct was supported in all three versions of the UCLA Loneliness Scale tested in the present study. Convergent validity was supported as the level of loneliness was correlated with the level of depression and anxiety for all three versions. There were no significant differences between gay and bisexual men, although significant differences were found across different educational levels. The study confirmed that all three versions of the UCLA Loneliness Scale were comparable with satisfactory reliability and validity in Taiwanese sexual-minority men.

Validation of the Student Athletes' Motivation Toward Sports and Academics Questionnaire (SAMSAQ) for Korean College Student-Athletes: An Application of Exploratory Structural Equation Modeling

The purpose of this study was to validate the Korean version of the Student-Athletes' Motivation toward Sports and Academics Questionnaire (SAMSAQ) using exploratory structural equation modeling (ESEM). A total of 412 (men 77%; women 23%) South Korean collegiate student-athletes competing in 27 types of sports from 13 different public and private universities across South Korea were analyzed for this study. ESEM statistical approach was employed to examine the psychometric properties of SAMSAQ-KR. To assess content validity, the SAMSAQ-KR was inspected by a panel of content subject experts. The Athletic Identity Measurement Scale was used to obtain convergent validity. The results of this study illustrated that the SAMSAQ-KR appears to be a robust and reliable instrument.

A Single-Case Design Investigation for Measuring the Efficacy of Gestalt Therapy to Treat Depression in Older Adults with Dementia in Italy and in Mexico: A Research Protocol

Psychotherapy is one of the evidence-based clinical interventions for the treatment of depression in older adults with dementia. Randomised controlled trials are often the first methodological choice to gain evidence, yet they are not applicable to a wide range of humanistic psychotherapies. Amongst all, the efficacy of the Gestalt therapy (GT) is under-investigated. The purpose of this paper is to present a research protocol, aiming to assess the effects of a GT-based intervention on people with dementia (PWD) and indirect influence on their family carers. The study implements the single-case experimental design with time series analysis that will be carried out in Italy and Mexico. Six people in each country, who received a diagnosis of dementia and present depressive symptoms, will be recruited. Eight or more GT sessions will be provided, whose fidelity will be assessed by the GT fidelity scale. Quantitative outcome measures are foreseen for monitoring participants' depression, anxiety, quality of life, loneliness, carers' burden, and the caregiving dyad mutuality at baseline and follow-up. The advantages and limitations of the research design are considered. If GT will effectively result in the treatment of depression in PWD, it could enrich the range of evidence-based interventions provided by healthcare services.

The effect of loneliness and social support on the course of major depressive disorder among adults aged 50 years and older: A longitudinal study

BACKGROUND

Previous research indicates that social support, loneliness, and major depressive disorder (MDD) are interrelated. Little is known about the potential pathways among these factors, in particular in the case of adults aged 50 years and older and suffering from MDD. The objective was to investigate whether loneliness mediates the association between low social support and recurrent episodes of MDD.

METHODS

We used data from a cohort of the Spanish general population interviewed at three time-points over a 7-year period. We included 404 individuals aged 50+ suffering from MDD in the baseline assessment. A 12-month major depressive episode was assessed with the Composite International Diagnostic Interview (CIDI) at each interview. The University of California, Los Angeles Loneliness Scale was used to measure loneliness, whereas social support was assessed through the Oslo Social Support Scale. We tested cross-lagged and autoregressive longitudinal associations using structural equation modeling.

RESULTS

We identified two significant longitudinal mediation patterns: lower social support predicted higher subsequent levels of loneliness (Coef. = -0.16; p < .05), which in turn predicted an increase in MDD recurrence (Coef. = 0.05; p < .05).

CONCLUSIONS

Interventions focused on promoting social support among older adults suffering from MDD may decrease feelings of loneliness and prevent recurrent episodes of MDD.

The applicability of the UCLA loneliness scale in South Africa: Factor structure and dimensionality

This study examines the generalisability of the University of California Los Angeles Loneliness Scale Version 3 (UCLA-LS3) in a South African sample of young adults. In particular, it examined the normative data, reliability, and factor structure of this scale. The participants were young adults (N = 337) who were randomly sampled from a university population and they responded to the UCLA Loneliness Scale. It was found that the sample had higher loneliness scores than those reported in the literature, potentially suggesting that loneliness may be a significant mental health concern amongst this group. Women reported higher levels of loneliness than men. Reliability analysis (Cronbach’s alpha) and analysis of the influence of individual items on the mean, variance, and alpha demonstrated that UCLA-LS3 had highly satisfactory internal consistency in the sample. Confirmatory factor analysis (CFA) was used to test four conceptualisations of the factor structure of UCLA-LS3: a one-factor model, a correlated three-factor model, a bifactor model with two subscales, and a bifactor model with three subscales. Notably, CFA demonstrated that the two bifactor models are a better fit than the one-factor and correlated three-factor models and that the bifactor model with three subscales is marginally a better fit than the bifactor model with two subscales. Ancillary bifactor analysis confirmed the dimensionality of the scale as sufficient variance was accounted for by the three subscales, after the variance attributable to the total scale was partitioned out. Therefore, UCLA-LS3 is best conceptualised as comprising of three subscales (isolation, relational connectedness, collective connectedness), in addition to a total scale.

Systematic review of psychometric properties and cross-cultural adaptation of the University of California and Los Angeles loneliness scale in adults

This systematic review assessed the psychometric properties and the cross-cultural adaptation of the University of California and Los Angeles Loneliness scale (UCLA-LS) in adults. A systematic search of four electronic databases (PubMed, EMBASE, Scopus, and PsycINFO) was conducted from inception until March 2021. We followed the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines for data extraction and evidence synthesis. Eighty-one studies assessed the validity and reliability of the UCLA-LS, translated into many languages, and applied across several countries/societies. Three versions of the 20-item and nine short versions of the UCLA-LS with 3 to 20 questions were identified. High-quality evidence supported the internal structure of the UCLAs: 4, 6, 7 and 10, while low-to moderate-quality evidence supported the construct validity of the UCLAs: 3, 4, 6, 8, 16 and 20. Moderate-quality evidence supported the test-retest reliability of version 3 UCLA-20 with excellent interclass coefficients values of 0.76-0.93. The UCLAs: 4, 6, 7 and 10 had the most robust internal structure and may therefore be the most useful for informing clinicians and social psychologists engaged in assisting those with loneliness.

Three-item loneliness scale: psychometric properties and normative data of the Spanish version

Loneliness is a common social phenomenon across countries with negative effects in health. Thus, the measurement of loneliness is of paramount importance. The Three-Item Loneliness Scale (TILS) was designed to be used in large-population surveys as a quick measure of loneliness. The aim of this study is to provide a Spanish validation of the TILS. A representative sample of the Spanish population (N = 1951) was used. We analysed the psychometric properties, factor structure, and distribution demographics characteristics of the Spanish TILS. Analyses showed differences regarding age, gender, educational level, employment status, household composition and annual gross income in line with previous literature. The confirmatory factor analysis revealed a unifactorial structure, with significant moderate correlations between the TILS and depression, anxiety, paranoia and well-being, and mild significant correlations with belongingness and mistrust. The internal consistency of the Spanish TILS was good (α = 0.82). Our study indicates that the TILS is a valid and reliable measure of loneliness in the Spanish population. Loneliness is a modern epidemic and a precursor of mental and health problems that reduced the quality of life. Therefore, it is important to have reliable measures of this phenomenon.

Psychological Adjustment in Spain during the COVID-19 Pandemic: Positive and Negative Mental Health Outcomes in the General Population

In the midst of the COVID-19 epidemic, Spain was one of the countries with the highest number of infections and a high mortality rate. The threat of the virus and consequences of the pandemic have a discernible impact on the mental health of citizens. This study aims to (a) evaluate the levels of anxiety, depression and well-being in a large Spanish sample during the confinement, (b) identify potential predictor variables associated to experiencing both clinical levels of distress and well-being in a sample of 2,122 Spanish people. By using descriptive analyses and logistic regression results revealed high rates of depression, anxiety and well-being. Specifically, our findings revealed that high levels of anxiety about COVID-19, increased substance use and loneliness as the strongest predictors of distress, while gross annual incomes and loneliness were strongest predictors of well-being. Finding of the present study provide a better insight about psychological adjustment to a pandemic and allows us to identify which population groups are at risk of experiencing higher levels of distress and which factors contribute to greater well-being, which could help in the treatments and prevention in similar stressful and traumatic situations.

Gender Differences in Stress- and Burnout-Related Factors of University Professors

The aim of the present study was to analyse the gender differences in stress-related factors of university professors. A cross-sectional study was carried out, where gender differences in psychological, nutrition, physical activity, and oral health stress-related factors were analysed in 470 Spanish university professors (58.7% male and 41.3% female, 42.1 ± 9.2 years) through a compendium of questionnaires. The results showed how females presented significantly (p ≤ 0.05) higher scores than males in perceived stress (females: 22.15 ± 4.40 vs. males: 19.69 ± 3.61), emotional exhaustion (females: 20.86 ± 9.51 vs. males: 16.44 ± 9.12), and neuroticism (females: 5.53 ± 1.97 vs. males: 4.77 ± 1.96). These results may be related to higher probabilities to suffer the burnout syndrome, showing possible physical symptoms of this psychological disorder such as dry mouth and gastritis or heartburn. We concluded that female professors presented higher burnout perceived stress, emotional exhaustion, and neuroticism levels than males. Females also presented higher dry mouth, gastritis, and heartburn than males. Female professors showed healthier nutritional habits than males, presenting higher consumption of milk products and fruit per day, a higher number of meals, and less eating between hours and fried food consumption. Nevertheless, females consumed fewer water glasses and practised less weekly sport than male professors.

Loneliness in adolescence: a Rasch analysis of the Perth A-loneness scale

PURPOSE

The psychometric properties of the Perth A-loneness Scale (PALs) have been extensively validated using classical test theory, but to date no studies have applied a Rasch analysis. The purpose of this study was to validate the PALs four subscales, using Rasch analysis.

METHODS

Responses from 1484 adolescents (58% female, mean age = 12.8 years), 131 of whom had a diagnosed neurodevelopmental disorder, from 10 Western Australian secondary schools were included in the Rasch analysis. Overall fit, individual item fit, local response dependence, dimensionality, operation of response categories, and differential item functioning (DIF) were examined.

RESULTS

The Rasch analysis supported the factor structure of the PALs. A reasonable to high reliability was obtained for each of the subscales. Participants did not distinguish consistently between the higher categories 'very often' and 'always' on three of the subscales. No item showed Differential Item Functioning (DIF) for neurodevelopmental disorder status and age. One item on each of the Positive and Negative Attitude to Aloneness subscales showed DIF for gender.

CONCLUSION

The results support the interval scale measurement properties of the PALs and provide clinicians and researchers with a measure to assess adolescent loneliness, a construct strongly associated with a constellation of mental health problems.
