Psychometric properties and confirmatory factor analysis of the UCLA loneliness scale

This study investigated the psychometric properties of the UCLA Loneliness Scale. Test-retest and internal consistency reliability were found to be highly acceptable, and support for the concurrent related validity of the scale was also indicated. Confirmatory factor analysis provided support for the unidimensionality of the scale. Evidence was found that the scale is not multivariate normal and in fact appears to be bimodal. Implications point to the need to reconsider the nature of the loneliness construct and to develop conceptually or theoretically based models for testing.

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

Loneliness is a subjective and unpleasant experience associated to a variety of physical and mental health problems. Older people face an elevated risk of loneliness. It is measured through self-reported questionnaires, among which the most widely used one is the University of California, Los Angeles (UCLA) Loneliness Scale. The latest version of this scale is called UCLA-3, and it has not been validated in Spanish elderly population. This article aims to present a validation study of the Spanish version of the UCLA-3 for its use with older people, by establishing its reliability and validity. Data were obtained from the second wave of a longitudinal research conducted with older adults attending Lifelong Learning programs. The sample consisted of 335 people aged 55 years old or older. Sociodemographic data were collected, and loneliness was measured with the UCLA-3 and the de Jong Gierveld Loneliness Scale. Results have partially replicated a three factor structure already found in the literature in other populations. The present work provides relevant and innovative evidence, as this is the first time that the UCLA-3 was analysed using ESEM statistical approach in a Spanish elderly sample.     

Reliability data for a Greek translation of the Revised UCLA Loneliness Scale: comparisons with data from the USA.

A Greek translation of the Revised UCLA Loneliness Scale was internally reliable (alpha = .89), after eliminating Item 4, and significantly correlated with the English version (r = .94) for a sample of bilingual students. Weiss's distinction between social loneliness and emotional loneliness was also reliably identified in the Greek translation. Loneliness scores in Greece were significantly higher than in the USA. The translation seems to be sufficiently reliable to warrant further use with Greek individuals.     

Reliability of the UCLA Loneliness Scale in opiate dependent individuals

The purpose of this study was to examine the internal consistency and test-retest reliability of the self-report University of California, Los Angeles, Loneliness Scale (UCLA LS; Russell, 1996) in methadone maintenance patients at an urban university hospital. A diverse sample of 117 patient volunteers completed a standardized interview that included the UCLA LS. A total of 67 participants returned after a minimum of 14 days for a follow-up session to complete an identical assessment but with a different researcher. We examined internal consistency and test-retest reliability in the total sample and in groups stratified by gender, race, ethnicity, and education. Across strata, the UCLA LS showed adequate to high internal consistency and good to excellent test-retest reliability. The UCLA LS was highly correlated with a measure of perceived belonging, supporting criterion validity. Findings support the use of the UCLA LS with methadone maintenance patients.     

How lonely are gay and lesbian youth?

UCLA Loneliness Scale (8-item version) scores in a sample of 384 gay and lesbian adolescents support the hypothesis that such youths are especially vulnerable to loneliness.     

A short-form measure of loneliness

The revised UCLA Loneliness Scale (ULS-20) and a four-item short form (ULS-4) are widely used in personality research (Russell, Peplau, & Cutrona, 1980). In an exploratory factor analysis of the ULS-20, we identified eight items that loaded substantially on the first factor. These items were combined to form an alternative short-form measure, the ULS-8. The results of this study indicate that the ULS-8 is reliable, valid, and a better substitute for the ULS-20 than is the ULS-4. Consistent with the previous research, the loneliness measures (ULS-20, ULS-8, ULS-4) were strongly related to socially undesirable personality characteristics, but loneliness was uncorrelated with the six different health-related behaviors (exercise, meal regularity, alcohol use, hard drug use, smoking, and hours of sleep) assessed in this study.

Sex differences in social support, loneliness, and depression among Korean college students

This study examined the sex differences in reports of social support (network size and satisfaction), loneliness, and depression among Korean college students and examined whether measures of social support and loneliness predicted depression scores. In the sample were 452 college students enrolled in four universities in Korea. The women reported a larger social support network size and being less satisfied with their support than the men. Women reported higher scores on the Revised UCLA Loneliness Scale and the Beck Depression Inventory than men. Social support satisfaction scores and network size on the Social Support Questionnaire-6 and scores on the Loneliness Scale predicted scores on Depression in both the groups. Loneliness was the largest predictor of Depression for either sex. The amount of variance in Depression accounted for by Loneliness was 35% for women and 24% for men.     

Stress, hope, and loneliness in young adolescents

A sample of 134 young adolescents attending a middle school responded to the Perceived Stress Scale, the Hopefulness Scale for Adolescents, and the Revised UCLA Loneliness Scale. Correlational analyses indicated that higher scores on stress were significantly associated with lower scores on hope (r = -.55) and higher scores on loneliness (r = .52). Unlike an earlier study with predominately ethnic minority adolescents, the present findings with predominately Euro-American adolescents supported the relationship proposed between stress and hope; the relationship proposed between stress and loneliness was supported.

Internet chat room use, satisfaction with life, and loneliness

In this study, 50 chat room users responded online to the Satisfaction With Life Scale, the Revised UCLA Loneliness Scale, and demographic questions which included time spent per week in Internet chat rooms. Time spent in chat rooms was positively correlated with loneliness but only weakly and negatively related to satisfaction with life.     

Psychological correlates of optimism in college students

This study assessed optimism held by 300 college students at a midwestern university using Scheier and Carver's Life Orientation Test. Optimism ratings were compared to measures of psychological functioning. Analysis showed that optimism was significantly associated with all of the adjustment measures (social, academic, personal, and goal commitment) assessed with Baker and Siryk's Student Adaptation to College Questionnaire, higher self-esteem measured with Rosenberg's Self-esteem scale, and with lower ratings of loneliness as assessed with the Revised UCLA Loneliness Scale.     

Reliability and Validity of a French Translation of a Short Scale of Attitude Toward Christianity

The reliability and validity of a French translation of the 7-item short form of the Francis Scale of Attitude toward Christianity was examined among a sample of 462 female French university students. Analysis supports the reliability and validity of the scale and commends it for further use among French speaking samples.     

The Multidimensional Child and Adolescent Depression Scale: psychometric properties

Based on previous factor analyses of child and adolescent depression inventories, the following eight basic dimensions were identified, i.e., Pessimism, Weak Concentration, Sleep Problems, Anhedonia, Fatigue, Loneliness, Low Self-esteem, and Somatic Complaints. Each dimension was assessed by five items, so the Multidimensional Child and Adolescent Depression Scale has 40 brief statements answered on a 3-point intensity scale, i.e., None, Some, and A lot. The eight dimensions have good factorial validity and acceptable to good alpha and test-retest reliability, and good criterion-related validity using three self-report depression scales. The total scale score has from good to high coefficients of reliability and validity. The highest mean scores were on Fatigue and Anhedonia for Kuwaiti boys and girls, respectively, while the Loneliness subscale has the lowest mean score for both sexes. Girls attained significantly higher mean scores than boys for the total score as well as on all dimensions, with the exception of weak concentration. The scale has two compatible Arabic and English versions. It was designed to be useful in defining the profile of children's and adolescents' depression.     

Spanish adaptation of the Need for Closure Scale

The Need for Cognitive Closure (NCC) refers to the motivation to seek and maintain a definitive answer to a given problem. This mental closure allows people to avoid confusion, ambiguity and uncertainty. The NCC plays a critical role in a variety of processes of diverse nature, including intra-personal (e.g., the higher the NCC, the less generation of hypothesis), inter-personal (e.g., decreased empathy), intra-group (e.g., increased desire for consensus), and inter-group (increased in-group favouritism) phenomena. The goal of the present research was to provide a Spanish adaptation of Antonio Pierro and Arie Kruglanski's Revised NCC Scale (2005, Rev NfCS), examining the reliability and the validity of participants' scores. In the present studies, it was found that the Spanish version of the scale had acceptable internal reliability and adequate factor structure (Study 1), as well as acceptable test-retest reliability and adequate discriminant validity with regard to the scores in another measure of individual differences such as the Need for Cognition (NC, Study 2).     

Depression and its relation to loneliness and religiosity in Indonesian Muslim adolescents

This study was initiated to assess the relations between religiosity, depressive symptoms, and loneliness in a sample of 452 Indonesian Muslim 13- and 16-year-old adolescents. Religiosity was operationally defined as participation in required and optional religious activities; Depression was assessed using the Center for Epidemiological Studies Depression Scale; and Loneliness was assessed using the UCLA Loneliness Scale. Religiosity was negatively associated with depression despite controlling for loneliness, gender, and grade. Religiosity was not associated with loneliness, suggesting discriminant validity in the relation between religiously and depression. It is important in future research to examine the mechanisms by which religiosity serves as a protective factor for Indonesian Muslim adolescents.     

Personality and loneliness

The relationship between Eysenck's major personality factors and responses to the Revised UCLA Loneliness Scale were examined. E was related to loneliness for both males and females. Females also showed a moderately high correlation between N and loneliness. Regression analyses indicated a substantially stronger relationship between the Eysenck factors and loneliness for females than males.     

Comparison of four short forms of the French adaptation of the Wechsler Adult Intelligence Scale – Fourth Edition (WAIS-IV)

IntroductionThe Wechsler Intelligence Scale for Adults - 4^th Edition (WAIS-IV) is widely used in France and French-speaking countries for clinical assessment and research. This scale has excellent metric qualities; there is ample evidence of the validity and reliability of its scores. However, it takes 60 to 90 min to complete the full test. That can be problematic in research where time is limited and when examining very disturbed patients. In such cases, a short form of the WAIS-IV may be useful. Unfortunately, no short form of the French version of WAIS-IV has yet been validated using the standardization sample.ObjectiveThe aim of the present study was to identify an abbreviated form of WAIS-IV with sufficient validity and reliability to replace, in some cases, the full test.MethodFour short forms were developed taking into account the fidelity and the correlation with the FIQ of the subtests included in each of form. The metric qualities the four short forms were compared using the standardization data of the French WAIS-IV. The standardization was done using the results of a sample of 876 individuals representative of the French population from 16 to 79 years 11 months.ResultsThe analyzes showed that a short form including Information, Matrices, Arithmetic and Code provides a fairly good estimate of the FIQ. The fidelity of the estimated IQ was 0.94 and its correlation with the FIQ was 0.91. However, the average of the absolute differences between the IQ calculated with this short form and the IQ calculated with the full form was 4.24 points, with a standard deviation of 3.15 points. These differences could lead to misidentification of some individuals tested with the short form.ConclusionThe proposed short form provides a sufficient approximation of the FIQ to be used in research where the collective results are more important than those of individuals. This short form, however, does not provide an IQ measure as robust as the full form. It should therefore be used with caution only when using the full form is not possible.
