Convergent and discriminant validation of a children's life satisfaction scale: Its relationship to self- and teacher-reported psychological problems and school functioning

Two studies are reported that provide additional validity evidence for the Students' Life Satisfaction Scale (SLSS: Huebner, 1991a). In the first study, evidence for the convergent validity of the SLSS is provided by significant negative correlations with measures of depression and loneliness and a significant positive correlation with a measure of self-esteem. Additionally, as evidence of discriminant validity, the SLSS failed to differentiate a normally achieving group of students from a group of at risk students. In the second study, the pattern of correlations between the SLSS, selected demographic variables, IQ scores, and a measure of teacher-reported school behavior problems provided evidence of cross-method convergent and discriminant validity. The SLSS was also able to differentiate a group of emotionally handicapped students from non-emotionally handicapped students. The implications of the findings for further study of the subjective well-being of children are discussed briefly.     

The extended satisfaction with life scale: Development and psychometric properties

The development and psychometric properties of the Extended Satisfaction With Life Scale (ESWLS) are described in detail. The ESWLS is a 50-item self-report scale that measures satisfaction with life in nine domains. It can be completed by most people in under 20 minutes and can be used by researchers and clinicians. The readability of the ESWLS was estimated to be between the seventh and tenth grade levels. Internal consistency, estimated by coefficient α, ranged from 0.81 to 0.96 for the individual subscales. Two-week test-retest reliability coefficients ranged from 0.74 to 0.87. Results of exploratory and confirmatory factor analyses strongly supported the factor structure of the ESWLS. Preliminary evidence of convergent and discriminant validity is provided as well as preliminary norms.     

The Early Development Instrument: An Examination of Convergent and Discriminant Validity

The convergent and discriminant validity of the Early Development Instrument (EDI), a teacher-rated assessment of children’s “school readiness”, was investigated in a multicultural sample of 267 kindergarteners (53% male). Teachers evaluations on the EDI, both overall and in five domains (physical health/well-being, social competence, emotional maturity, language/cognition, communication/general knowledge), were related to direct, child-based assessments of performance on two standardized measures of school readiness, and measures of phonological awareness and early social competence. Regression analysis indicated that together the four comparison measures accounted for 36% of variance in overall EDI scores, each making a significant and unique contribution. Results supported the convergent validity of overall EDI scores but not the discriminant validity of EDI domain scores. Moreover, correlations between EDI scores and comparison measures varied widely across teachers, suggesting considerable individual differences in teacher’s ability to evaluate school readiness relative to direct, child-based assessments, and confirming that the EDI is more appropriate for deriving inferences at higher aggregated levels such as community or region. The validation of EDI domain scores remains an important challenge in future research.     

A Measure of Subjective Happiness: Preliminary Reliability and Construct Validation

Using a 'subjectivist' approach to the assessment of happiness, a new 4-item measure of global subjective happiness was developed and validated in 14 studies with a total of 2 732 participants. Data was collected in the United States from students on two college campuses and one high school campus, from community adults in two California cities, and from older adults. Students and community adults in Moscow, Russia also participated in this research. Results indicated that the Subjective Happiness Scale has high internal consistency, which was found to be stable across samples. Test-retest and self-peer correlations suggested good to excellent reliability, and construct validation studies of convergent and discriminant validity confirmed the use of this scale to measure the construct of subjective happiness. The rationale for developing a new measure of happiness, as well as advantages of this scale, are discussed.     

A New Measure of Quality of Work Life (QWL) Based on Need Satisfaction and Spillover Theories

A new measure of QWL was developed based on need satisfaction and spillover theories. The measure was designed to capture the extent to which the work environment, job requirements, supervisory behavior, and ancillary programs in an organization are perceived to meet the needs of an employee. We identified seven major needs, each having several dimensions. These are: (a) health and safety needs (protection from ill health and injury at work and outside of work, and enhancement of good health), (b) economic and family needs (pay, job security, and other family needs), (c) social needs (collegiality at work and leisure time off work), (d) esteem needs (recognition and appreciation of work within the organization and outside the organization), (e) actualization needs (realization of one's potential within the organization and as a professional), (f) knowledge needs (learning to enhance job and professional skills), and (g) aesthetic needs (creativity at work as well as personal creativity and general aesthetics). The measure's convergent and discriminant validities were tested and the data provided support to the construct validity of the QWL measure. Furthermore, the measure's nomological (predictive) validity was tested through hypotheses deduced from spillover theory. Three studies were conducted – two studies using university employees and the third using accounting firms. The results from the pooled sample provided support for the hypotheses and thus lent some support to the nomological validity to the new measure.     

The Subjective Well-being Construct: A Test of its Convergent,Discriminant, and Factorial Validity

Using structural equation modeling, we found empirical support for the prevailing theory that subjective well-being consists of three domains: (1) cognitive evaluations of one’s life (i.e., life satisfaction or happiness); (2) positive affect; and (3) negative affect. Multiple indicators of satisfaction/happiness were shown to have strong convergent validity as well as discriminant validity from positive and negative affect. Positive and negative affect likewise exhibited discriminant validity from one another. At both the item and scale levels of analysis, we obtained an intercorrelated three-factor solution corresponding to the three proposed subjective well-being domains.     

Validation of the 12 Item Short form Health Survey in a Sample from Region Central Jutland

In 2010 the Danish regions started a new program of public health surveillance in collaboration with the national and local health authorities using the short form health survey (SF-12) for measuring and reporting on health related quality of life among the Danish adult population. The instrument has not, however, been validated in a Danish setting. The aim of this study was to assess the reliability and validity of the physical component summary (PCS) and the mental component summary (MCS) score of the 12-item short form health survey (SF-12) in a sample from Central Denmark Region. A total of 26,397 persons above the age of 25 were included in the analyses. Reliability was assessed by Cronbach’s α. The validity was assessed using known-groups comparisons and convergent validity. The factor structure was investigated through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The Cronbach’s α showed high reliability with a score of 0.90 and 0.85 for PCS and MCS respectively. The SF-12 discriminated well with respect to gender, age, educational status and long term illness. Individual items correlated higher with own hypothesized scales than with other scales and summary measures corroborating the convergent validity. The EFA gave a two-factor structure. Irrespective of the chosen rotation method (varimax and oblimin) the items related to PCS loaded on one factor and the items related to MCS loaded on another factor. The factor structure was validated with acceptable model-fit values in CFA. The SF-12 instrument is a reliable and valid measure of health related quality of life among the population of Central Denmark Region.     

Relationships between overall and life facet satisfaction: A multitrait-multimethod (MTMM) study

We extended research on the construct validity of overall and life facet satisfaction measures by (a) estimating relations among satisfaction constructs disattenuated for measurement error, and (b) controlling for spurious effects of common method variance, using confirmatory factor analysis (CFA) of multitrait-multimethod (MTMM) data. Results indicated strong support for convergent and discriminant validity, as well as for significant method effects. Results also indicated that corrected correlations among latent satisfaction variables were similar to their observed counterparts, suggesting that the attenuating effects of measurement error tend to balance spuriousness interjected by common method variance. Suggestions for future research include determining boundary variables which influence the direction of the relationship between overall and life facet satisfaction, and for identifying subgroups of individuals within which these relationships are homogeneous.     

Developing the University of the Philippines Loneliness Assessment Scale: A Cross-Cultural Measurement

As the existing scales to measure loneliness are almost all Western and there is no single scale developed cross-culturally for this purpose, this study is designed to develop a reliable and valid scale to measure the experience of loneliness of individuals from individualistic or collectivistic cultures. There are three samples for this study with a total of 495 male and female international (n = 202) and local (n = 293) participants (Age range 19–60 years). An initial pool of 70 item scale was administered to a sample of 202 participants (20–60 years old) from 41 countries of the world with collectivistic and individualistic cultures and the data was subjected to factor analysis using principal component extraction. Evidence shows a unidimensional factor loading. The extracted items were subjected to reliability test and 25 items were obtained for the final scale of the UP Loneliness Assessment Scale (UPLAS) with a Cronbach alpha of .93. Further analyses show the following findings: UPLAS has a significant correlation with R-UCLA Loneliness Scale providing evidence for its moderate concurrent validity; there is a significant and inverse relationship between the measures of UPLAS and Subjective Happiness Scale establishing its higher discriminant validity; UPLAS scores are significantly correlated with the measures of negative self-perceptions, depression, and several emotional states associated to loneliness and thus establishing a higher convergent validity. The designing of the UP Loneliness Assessment Scale as a cross-cultural measurement tool may contribute to more research interests in the domain of “negative perceptions” as the most contributing factor to loneliness across cultures.     

Convergent Validity and Test–Retest Reliability of the Authentic Happiness Inventory in Working Adults

This study aimed to test the convergent validity and test–retest reliability of a measure of happiness questionnaire; the authentic happiness inventory questionnaire (AHI), with a convenience sample of working adults (n = 30). Participants completed the AHI on two consecutive days. On the second day, participants also completed the Satisfaction with Life Scale (SWLS) and the positive and negative affect scale (PANAS). Internal consistency was determined using Cronbach alpha coefficients, test–retest reliability using a one-way intraclass correlation coefficient (ICC) model, and convergent validity using Pearson product-moment correlations. A further sample of working adults (n = 192) was included to conduct an exploratory factor analysis using principal component analysis (total n = 222). High internal consistency and overall test–retest reliability for the AHI was found (Cronbach alpha = .92 and ICC = .92, p < .001). There was a strong positive correlation between AHI and SWLS (r = .76, p < .005) and AHI and PANAS positive (r = .82, p < .005). There was a medium negative correlation between AHI and PANAS (r = .48, p < .005). Principal components analysis revealed the presence of five components with eigenvalues exceeding one, with one factor explaining 36.1 % of the variance. Findings confirmed the convergent validity and test retest reliability of the Authentic Happiness Inventory in working adults.

     

Convergent and Discriminant Validity of the WHOQOL-BREF Using a Multitrait-Multimethod Approach

The WHOQOL-BREF is a commonly used questionnaire in quality of life research. Previous research has shown that the four domains of the WHOQOL-BREF (physical health, psychological health, social relationships, and environmental health) are highly related. Whether these high correlations reflected the true relations across the domains or the influence of common method effect; however, is still unknown. This study examines the convergent and discriminant validity of the four domains of the WHOQOL-BREF by using the multitrait-multimethod (MTMM) approach to control the method effect. Two different samples, with a total of 186 and 201 adults, respectively, were used in the present study. Each participant filled out the WHOQOL-BREF questionnaires using four different scaling methods (Likert-type scale, visual analogue scale, pie scale, and partner rating). The covariance matrix of the MTMM result was analyzed with confirmatory factor analysis modeling. Two models were applied, including the correlated traits-correlated uniqueness (CTCU) model and the uncorrelated traits-correlated uniqueness (UTCU) model. Results showed that the CTCU model fit the data better than did the UTCU model, suggesting that the variables tapping the four domains of the WHOQOL-BREF have excellent convergent validity; the four domains have moderate correlations, indicating that the four domains are related but not identical.     

Dimensions of mental health: Life satisfaction,positive affect,anxiety and depression

Psychological well-being and psychological distress are often regarded as distinct, if not orthogonal dimensions of mental health. Based on analyses in this paper, we consider the distinction misleading. Four dimensions seem worth measuring in general population surveys: life satisfaction, positive affect, anxiety and depression. Furthermore, one of the well-being dimensions, life satisfaction, is quite strongly correlated with a distress dimension, depression. A person is unlikely to be both satisfied with life and depressed, but may be satisfied and anxious. The paper is based on convergent validity (exploratory and confirmatory factor analyses) and divergent validity assessments of a range of widely used measures, which were included in the Victorian Quality of Life Panel Survey, 1987.     

Preliminary Validation of the Brief Multidimensional Students' Life Satisfaction Scale (BMSLSS)

Two studies investigated the psychometricproperties of the Brief MultidimensionalStudents' Life Satisfaction Scale (MSLSS: Huebner, 1994). In Study 1, 221 middle schoolstudents completed the Brief MultidimensionalStudents' Life Satisfaction Scale (BMSLSS),Multidimensional Students' Life SatisfactionScale, Students' Life Satisfaction Scale (SLSS:Huebner, 1991a), Positive and Negative AffectSchedule-Children's Version (Laurent et al.,1999), Children's Social Desirability Scale(Crandall et al., 1965), and a one-item globallife satisfaction rating (GLLS). Students alsorated the importance of the BMSLSS five lifesatisfaction domains (Family, Friends, School,Self, Living Environment). The results revealedacceptable internal consistency reliability,criterion-related validity, and constructvalidity for the BMSLSS Total score forresearch purposes. Furthermore, evidence ofconvergent and discriminant validity for theBMSLSS domain scores was also obtained throughmultitrait-multimethod analyses. Finally, theresults failed to provide strong support forthe usefulness of importance scores inpredicting overall life satisfaction;unweighted BMSLSS scores were highly related toglobal life satisfaction (GLLS) scores. InStudy 2, 46 high school students completed theBMSLSS and MSLSS to test the generalizabilityof the convergent and discriminant validityfindings with older adolescents. The findingsrevealed stronger evidence of validity withthis age group. Overall, the findings offered preliminary support for the reliability andvalidity of the BMSLSS, suggesting that it canserve as a useful alternative to the longerMSLSS in studies with adolescents in whichbrevity is an important consideration.     

Exploring Time Perspective in Greek Young Adults: Validation of the Zimbardo Time Perspective Inventory and Relationships with Mental Health Indicators

In this article we examine the factorial structure of the Greek version of the Zimbardo Time Perspective Inventory (ZTPI; Zimbardo and Boyd in J Personal Soc Psychol 77:1271–1288, 1999), in a sample of 337 university students, using principal axis factoring (PAF) with oblique rotation, and its dimensionality using parallel analysis. Moreover, we evaluate the internal consistency reliability, the convergent validity (through associations with mental health indicators such as dispositional optimism, self-esteem, trait anxiety, depression, and proactive coping), as well as discriminant, and differential validity of this instrument. The results indicated that the ZTPI had a 5-factor structure (past negative, past positive, present fatalistic, present hedonistic, future). Correlational analyses indicated that an aversive view of the past, and a fatalistic attitude toward life were positively and significantly associated with trait anxiety and depression, while they were negatively correlated with self-esteem, proactive coping, and dispositional optimism. Future time perspective was positively associated with proactive coping, whereas a positive attitude toward the past was negatively associated with depression and trait anxiety. Psychometric properties of the five ZTPI scales were satisfactory (Cronbach’s alphas ranging from .710 to .845), thus facilitating the robust investigation of time perspective in Greek speaking populations. However confirmatory factor analyses revealed that the “positive attitude toward the past” dimension might not be a good indicator of time perspective. We discuss the theoretical implications of these findings for future studies of time perspective.     

Development and Validation of the Middle Years Development Instrument (MDI): Assessing Children’s Well-Being and Assets across Multiple Contexts

Few instruments provide reliable and valid data on child well-being and contextual assets during middle childhood, using children as informants. The authors developed a population-level, self-report measure of school-aged children’s well-being and assets—the Middle Years Development Instrument (MDI)—and examined its reliability and validity. The MDI was designed to assess child well-being inside and outside of school on five dimensions: (1) Social and emotional development, (2) Connectedness to peers and to adults at school, at home, and in the neighborhood, (3) School experiences, (4) Physical health and well-being, and (5) Constructive use of time after school. This paper describes the theoretical framework, selection of items and scales for the survey, and four studies that were conducted to revise the MDI and examine its psychometric properties. The findings indicate a theoretically predicted factor structure, high internal consistency, and document the convergent and discriminant validity of the MDI scales. The discussion delineates a plan for future validation studies that address further validity questions, such as predictive validity, measurement invariance, and fairness/bias, and provides a brief outlook of how the MDI may be used by practitioners, educators, and decision makers in schools and communities to motivate and inform action in support children’s well-being.     

A New Approach to the Study of Tolerance: Conceptualizing and Measuring Acceptance,Respect, and Appreciation of Difference

Previous empirical research on tolerance suffers from a number of shortcomings, the most serious being the conceptual and operational conflation of (in)tolerance and prejudice. We design research to remedy this. First, we contribute to the literature by advancing research that distinguishes analytically between the two phenomena. We conceptualize tolerance as a value orientation towards difference. This definition—which is abstract and does not capture attitudes towards specific out-groups, ideas, or behaviors—allows for the analysis of tolerance within and between societies. Second, we improve the measurement of tolerance by developing survey items that are consistent with this conceptualization. We administer two surveys, one national (Sweden) and one cross-national (Australia, Denmark, Great Britain, Sweden, and the United States). Results from structural equation models show that tolerance is best understood as a three-dimensional concept, which includes acceptance of, respect for, and appreciation of difference. Analyses show that measures of tolerance have metric invariance across countries, and additional tests demonstrate convergent and discriminant validity. We also assess tolerance’s relationship to prejudice and find that only an appreciation of difference has the potential to reduce prejudice. We conclude that it is not only possible to measure tolerance in a way that is distinct from prejudice but also necessary if we are to understand the causes and consequences of tolerance.

     

Development and Evaluation of a Parent-Employee Interrole Conflict Scale

We took a deductive (theoretically-based) approach to develop scales to measure a specific aspect of work-family conflict: interrole conflict between individuals' roles as parents and as employees, or parent-employee conflict (P-E conflict). Results supported (a) three empirically distinct aspects of P-E conflict: parenting interfering with work (PIW), work interfering with parenting (WIP) and general P-E conflict (G), (b) the discriminant validity of PIW, WIP, and G as compared to general work-family conflict (W-FC) and work role conflict (WRC), and (c) the nomological validity of P-E conflict scales in terms of predicted relationships with measures of other related constructs. Scale items are presented, and recommendations for scale use and future research directions are offered.     

Satisfaction Ratings of QOLPAV: Psychometric Properties Based on the Graded Response Model

A scale measuring quality of life (QOL) is important in adolescent research. Using the graded response model (GRM), this study evaluates the psychometric properties of the satisfaction ratings of the Quality of Life Profile Adolescent Version (QOLPAV). Data for 1,392 adolescents were used to check IRT assumptions such as unidimensionality and local item dependence (LID). The goodness of fit of the GRM to the data and the item characteristic curves were evaluated. The reliability and validity analyses included item/test information, Cronbach’s α, and convergent and discriminant validity. Differential item functioning (DIF) procedures were also performed to detect item bias. The results provide evidence that the items sufficiently measured one single dimension. Few pairs of questions were flagged as LID due to content or wording similarity. Five items did not fit the GRM, and 4 were low in item discrimination. The findings also suggest that the assessment had appropriate reliability and validity. The DIF impact on the assessment score was considered minor. Because QOLPAV includes a respondent’s perceived importance of various life aspects, a short form that only considers important life aspects in the overall QOL estimation for each respondent becomes feasible within the framework of IRT. Future studies focusing on the development of a QOL overall index using the items from QOLPAV are recommended.     

A Data-Driven Approach to Construct Survey-Based Indicators by Means of Evolutionary Algorithms

Despite growing understanding of resilience as a process associated with both individual capacities and physical and relational resources located in social ecologies, most instruments designed to measure resilience overemphasize individual characteristics without adequately addressing the contextual resources that support resilience processes. Additionally, most resilience studies have focused on children and youth, without significant attention to social ecological factors that promote post-risk adaptation for adults and how this is measured. Consequently, a key issue in the continued study of adult resilience is measurement instrument development. This article details adaptation of the Child and Youth Resilience Measure for use with an adult population. The article draws on data from a mixed methods study exploring the resilience processes of Irish survivors of clerical institutional abuse. The sample included 105 adult survivors (aged 50–99) who completed the RRC-ARM and the Warwick–Edinburgh Mental Well-being Scale (WEMWBS) during the first phase of the study. Exploratory factor analysis, Cronbach Alpha and MANOVA were conducted on the data. EFA identified five factors; social/community inclusion, family attachment and supports, spirituality, national and cultural identity, and personal competencies. The RRC-ARM shows good internal reliability and convergent validity with the WEMWBS, with significant differences on scale scores for men and women, as well as place of residence. This exploratory adaptation supports the potential of the RRC-ARM as a measure of social ecological resilience resources for adult populations and may have particular applications with vulnerable communities. Further validation is required in other contexts and specifically with larger samples.     

Psychometric Evaluation of the Tagalog and German Subjective Happiness Scales and a Cross-Cultural Comparison

The Subjective Happiness Scale (SHS) has recently been developed as a more complete measure for the assessment of molar subjective happiness. In the present study, we report on the translation and validation of German and Tagalog versions of the SHS and conduct an initial cross-cultural examination of subjective happiness. In Study 1, 960 participants in Austria completed a German version of the SHS, which showed a unidimensional structure, good internal consistency, and good convergent validity with other measures of subjective well-being. In Study 2, 182 participants in the Philippines completed a Tagalog version of the scale, which likewise had a unidimensional structure, high internal consistency, and good convergent validity. Finally, the results of Study 3 indicate that there were significant cross-cultural differences in subjective happiness. Specifically, participants in individualist Austria and Britain had higher SHS scores than their counterparts in collectivist Malaysia and the Philippines. Limitations of these studies are discussed.
