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.

     

Psychometric Properties of the Satisfaction with Life Scale among Turkish University Students,Correctional Officers,and Elderly Adults

This study aims to extensively examine the psychometric properties of adapted version of the Satisfaction with Life Scale (SWLS) in different Turkish samples. In order to test the psychometric properties of the SWLS three separate and independent samples are utilized in this study, namely university students (n = 547), correctional officers (n = 166), and elderly adults (n = 123). Concerning the reliability of the scale, internal consistency and item-total correlation coefficients are found to be satisfactory for all three samples. As for the validity studies, concurrent validity of the scale is supported in all three samples by revealing the association of SWLS with conceptually related measures, which included depression, self-esteem, positive affect and negative affect, work stress, and monthly income measures. Discriminant validity is examined only in the sample of university students, and SWLS revealed a non-significant correlation with a conceptually unrelated construct (i.e., willingness to self-censor). Consistent with the original scale, a single-factor solution model reveals an adequate fit in all three different samples. Furthermore, confirmatory factor analysis with multi-group comparisons performed demonstrates that SWLS has the same theoretical structure for three different groups on the basis of a single-factor solution model. The theoretical and practical implications of this study are discussed.     

Life satisfaction in persons with schizophrenia living in the community

Subjective well-being is an increasingly common indicator of adequacy of psychiatric services. An easy-to-administer assessment tool of subjective well-being that is conceptually sound, valid, and reliable is needed for use in persons with schizophrenia. The purpose of this paper was to validate the 5-item Satisfaction with Life Scale (SWLS)-Taiwan version for persons with schizophrenia living in the community. Specifically, the internal consistency reliability, construct validity and criterion-related validity were examined. Data were obtained from a total of 443 patients with schizophrenia at multiple areas of Taiwan. Item analysis and confirmatory factor analysis were performed. The results revealed that the SWLS had good international consistency reliability and suggested a single-factor structure in life satisfaction among this patient group. The SWLS has good criterion-related validity with the brief World Health Organization Quality of Life Assessment (WHOQOL-BREF). It is concluded that the SWLS is a sound measurement to be used with persons with schizophrenia living in the community.     

Psychometric Evaluation of the Malay Satisfaction With Life Scale

The Satisfaction With Life Scale (SWLS) is one of the most widely used scales for the measurement of subjective well-being across the globe, but no satisfactory version exists for use among Malay-speaking populations. The present study reports on the translation of a new Malay SWLS and examines its psychometric properties in a community sample of 816 Malay and 738 Chinese participants from Malaysia. Results showed that the Malay SWLS had good internal consistency (Cronbach’s α = 0.83). Confirmatory factor analysis showed support for a unidimensional factor structure which remained invariant across sex and ethnic group. These results suggest that the Malay SWLS is a valid and reliable measure of life satisfaction for Malay-speaking samples, and extends the list of available scales for measuring subjective well-being among such groups.     

Life Satisfaction in Brazil: Testing the Psychometric Properties of the Satisfaction With Life Scale (SWLS) in Five Brazilian Samples

The aim of this paper was to validate the Brazilian-Portuguese version of the Satisfaction With Life Scale (SWLS), presenting evidence of its reliability and construct and criterion-related validity. A large Brazilian sample (2,180 participants), from five different populations (undergraduate and high school students, general population, elementary school teachers, and physicians), was considered. The results confirmed the single factorial structure and reliability (0.77 < Cronbach’s α < 0.88, mean α = 0.81) of the SWLS. Supporting its criterion-related validity, the SWLS correlated positively with positive affect and negatively with both negative affect and psychological distress across all five samples. The findings indicate that the Brazilian-Portuguese version of the SWLS is a valid instrument to use with diverse Brazilian 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.     

Investigating Validity Evidence of the Satisfaction with Life Scale Adapted for Children

This study introduces the Satisfaction with Life Scale adapted for Children (SWLS-C) and presents psychometric findings regarding its validation. The SWLS-C was adapted from the Satisfaction with Life Scale (SWLS; Diener et al. 1985), which is one of the most commonly used measures to assess satisfaction with life in adults. Three subject matter experts adapted the SWLS by changing the wording of the item stem and response format in order to make it more understandable for children. A stratified random sample of 1,233 students (48% girls) in grades 4–7 (mean age 11 years and 7 months) provided data on the SWLS-C and measures of optimism, self-concept, self-efficacy, depression, emphatic concern, and perspective taking. The SWLS-C demonstrated a unidimensional factor structure and high internal consistency. Furthermore, differential item functioning and differential scale functioning analyses indicated that the SWLS-C measures satisfaction with life in the same way for different groups of children (i.e., with regard to gender, first language learned at home—English vs. other language(s) than English—and across different grades) at the item and at the scale level. Associations between scores on the SWLS-C and demographic variables were statistically non-significant or of small effect size. In addition, the SWLS-C showed evidence of convergent and discriminant validity in relation to the other measures. Our results indicate that the SWLS-C is a psychometrically sound instrument that demonstrated evidence of construct validity for this age group. Limitations and future directions are discussed.     

Can the Web-Form WHOQOL-BREF be an Alternative to the Paper-Form?

The purpose of this study was to test whether the web version is an alternative to the paper version of the short version of the World Health Organization Quality of Life assessment (WHOQOL-BREF). Two studies were conducted. Study 1 used crossover self-controlled trials with 80 participants to compare the web and paper versions and to determine the test–retest reliability of the web version. Study 2 used data from 1,016 web participants to analyze the internal consistency and concurrent and construct validity of the web version. The correlations of domain scores between the web and paper versions ranged from 0.71 to 0.85. Dependent t tests showed no significant differences in domain scores between these two versions. The intra-class correlation coefficients (ICC) for test–retest reliability of web version ranged from 0.79 to 0.91. The Cronbach’s α for internal consistency reliability ranged from 0.60 to 0.83. Multiple regression models indicated that the web version has good concurrent validity. Confirmatory factor analysis (CFA) for the second-order hierarchical factor model also supported the construct validity of the web version. The web version of the WHOQOL-BREF can be the alternative to the paper version for health-related quality of life (HR-QOL) evaluation.     

Evaluation of Attitudes Toward Same-Sex Parenting in the Italian Context: Adaptation of a French Questionnaire

ABSTRACT

This study investigated the psychometric properties of the Italian version of a French scale to detect attitudes toward same-sex parenting. The Italian sample was split into two subsamples. On one, exploratory factor analysis (EFA) was conducted to detect the factor structure of the Italian scale, and on the other, confirmatory factor analysis (CFA) was run to find the data’s best fit model. The scales’ internal consistency was evaluated using Cronbach’s alpha. The questionnaire’s convergent validity was also evaluated. EFA extracted a four-factor solution, in accordance with the original French scale’s validation study. CFA showed that the translated scale had good consistency, similar to that of the original version, showing satisfactory internal consistency for three of four subscales. There will be benefits to further validation studies of the translated scale on the Italian population and it may possibly be innovative and useful in both research and social fields.     

Psychometric Evaluation of the Serbian Version of the Multidimensional Students’ Life Satisfaction Scale

The main purpose of this study was to evaluate psychometric properties of the Serbian version of the Multidimensional Students’ Life Satisfaction Scale (MSLSS). The research was carried out on a sample of 408 high school students (250 females, 158 males), with the mean age 16.6. The Serbian version of the MSLSS has demonstrated good psychometric properties. The internal consistency coefficients (Cronbach’s α) for the MSLSS domain and total scores were adequate. Support for the validity of the MSLSS was provided by the pattern of correlations with various positive and negative indicators of well-being. However, it has been suggested that shortening the scale from 40 items to 25 items could provide more accurate measure of adolescents’ life satisfaction for the future research.     

Examining the relationship between global and domain measures of quality of life by three factor structure models

This study examined the relationship between global and domain measures of quality of life from a psychometric perspective by three different factor structure models. Three hundred and four students at National Taiwan University participated in this study. They completed the Satisfaction with Life Scale (SWLS, a global measurement for quality of life) and the WHOQOL-BREF (a domain-specific measurement for quality of life). Three models were specified to examine the relationships among scores of the SWLS and the WHOQOL-BREF. The first model was a common factor model in which scores of the SWLS and the WHOQOL-BREF were all influenced by a single factor. The second model was a correlated two-factor model in which scores of the SWLS were influenced by one factor and scores of the WHOQOL-BREF influenced by another factor, with these two factors being allowed to be correlated. The third model was a three-factor model, in which one factor (representing quality of life) influenced the scores of the SWLS and the WHOQOL-BREF, another factor (representing global approach) only influenced the scores of the SWLS, and yet another factor (representing domain approach) only influenced the scores of the WHOQOL-BREF. The results showed that the third model was the best, suggesting that global measures (the SWLS) and domain measures (the WHOQOL-BREF) did assess the same construct on quality of life, however, the measurement approaches they adopted (global or domain approach) also have substantial impact on the meaning of scores.     

Translation and Validation of the Malay Subjective Happiness Scale

The Subjective Happiness Scale (Lyubomirsky and Lepper, Social Indicators Research, 46, 137–155, 1999) is a brief measure for assessing subjective happiness. The reliability and validity of the Malay version of the Subjective Happiness Scale was investigated in a community sample of 290 Chinese and 227 Malays in Malaysia. Results showed that the Malay Subjective Happiness Scale has excellent internal consistency, a unitary structure, and stability over a 30-day period and across ethnic groups. Moreover, the Malay version of the scale exhibited good convergent validity with single-item happiness scales. The availability of the Malay Subjective Happiness Scale is expected to facilitate the examination of happiness in Malay-speaking populations.     

Quality of Life in Intentional Communities

The present study was initiated to investigate levels and predictors of wellbeing among inhabitants of intentional communities (ICs). An anonymous, Internet-based questionnaire was distributed to US and Canadian ICs. Responses were obtained from 913 members. Wellbeing was measured by the widely used satisfaction with life scale (SWLS). Hierarchical linear regression analyses were run to test the predictive validity of Social support, Identity fusion, Meaning in life, Community satisfaction and Life change, and Religious activity above and beyond demographic variables and personality traits. Mean scores on the SWLS were estimated to 5.27 and 5.47 (1–7 scale) for men and women, respectively. The full model explained 41.4% of the variance for men and 38.2% for women. Personality explained 13.4 (men) and 14.4% (women) of the variation, while demographic variables only had a minor impact. Overall, presence of Meaning in life and Social support were the most important predictors. The IC inhabitants reported wellbeing on par with the highest scores previously published. The findings support the contention that sustainability, in the form of a communal lifestyle of low ecological footprint, may be promoted without forfeiting wellbeing.     

Reimagining the General Health Questionnaire as a measure of emotional wellbeing: A study of postpartum women in Malta

BackgroundPostpartum health has been subject to a focus on psychological morbidity, despite positive associations between postpartum recovery and maternal emotional wellbeing. There are currently many validated tools to measure wellbeing and related concepts, including non-psychiatric morbidity. The General Health Questionnaire, 12 items (GHQ-12) is one such instrument, widely used and validated in several languages. Its use in postpartum settings has been documented with disagreement about the instrument's utility in this population, particularly in relation to scoring method and threshold. The GHQ-12 has never been translated into Maltese. This study explored the psychometric properties of the GHQ-12 in a Maltese postpartum population to consider if the use of a different scoring method (visual analogue scale) in the GHQ-12 can determine postpartum wellbeing.MethodsOne hundred and twenty-four postpartum women recruited from one hospital in Malta completed the translated and adapted GHQ-12 as a wellbeing measure (GHQ-12(WB)) at four postpartum time points. The psychometric properties of the GHQ-12(WB) were explored using confirmatory factor analysis, discriminant and divergent validity and reliability analysis.ResultsThe GHQ-12(WB) demonstrated good divergent and known-groups validity and internal consistency. No models offered a good fit to the data. The overall consistent best-fit to the data was an eight item, two factor model (GHQ-8). Model fit improved across all models in terms of CFI at 13 weeks.ConclusionFindings generally support the reliability and validity of the Maltese version of the GHQ-12(WB). Model fit changes over time reflect the dynamic nature of postpartum recovery. Further evaluation of the GHQ-8(WB) is recommended.     

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.     

Can Well-Being be Measured Using Facebook Status Updates? Validation of Facebook’s Gross National Happiness Index

Facebook’s Gross National Happiness (FGNH) indexes the positive and negative words used in the millions of status updates submitted daily by Facebook users. FGNH has face validity: it shows a weekly cycle and increases on national holidays. Also, happier individuals use more positive words and fewer negative words in their status updates (Kramer 2010). We examined the validity of FGNH in measuring mood and well-being by comparing it with scores on Diener’s Satisfaction with Life Scale (SWLS), administered to an average of 34 Facebook users every day for a year, then aggregated by day, week, month, quarter and half year. FGNH and SWLS were not significantly correlated, with a negative correlation coefficient. Also, aggregated SWLS scores showed a positive relationship with numbers of negative words in status updates. We conclude that FGNH is a valid measure for neither mood nor well-being; however, it may play a role in mood regulation. This challenges the assumption that linguistic analysis of internet messages is related to underlying psychological states.     

The Measurement and Evaluation of Social Attitudes in Two British Cohort Studies

This paper presents an empirical evaluation of the internal consistency and validity of six attitudes scales assessing left–right beliefs, political cynicism, antiracism, libertarian-authoritarian views, and gender equality (two versions) in two large nationally representative samples of the British population born in 1958 and 1970. In the 1958 National Child Development Study (NCDS) 10,827 participants completed a series of social attitudes items in 1991 at age 33 and again in 2000 at age 42. In 2000 at age 30, 11,114 participants of the 1970 British Cohort Study (BCS70) completed a broadly similar set of items of which 8,906 participants had also completed a shorter version of the same social attitudes questionnaires 4 years earlier in 1996, at age 26. Based on the data from the two cohorts we conducted confirmatory analyses to evaluate the factor structure of the six social attitudes scales using Structural Equation Modelling. In addition we tested the predictive as well as concurrent validity of the scales by establishing associations within the scales across time and their associations with indicators of voting behaviour and political interest. All six attitudes scales have good internal reliability and factorial stability, and external validity, they are robust and consistent over time. The measures also have wide applicability for researchers interested in social attitudes and behaviour in times of social change.     

Validating the Portuguese Version of the Satisfaction With Life Scale in an Elderly Sample

Life satisfaction is referred to a cognitive, judgmental process (Diener et al. in J Pers Assess 49:71–75, 1985), in which person’s quality of life is globally assessed according to his/her chosen criteria (Shin and Johnson in Soc Indic res 5:475–492, 1978). Thus, life satisfaction is a conscious cognitive judgment, based on the comparison of one’s life with a self-imposed standard or set of standards, which lead to a global assessment of life (Pavot and Diener in Psychol Assess 5:164–172, 1993). Among the many scales developed to measure life satisfaction, the Satisfaction With Life Scale (SWLS, Diener et al. in J Pers Assess 49:71–75, 1985) is one of the global life satisfaction scales more often used in the research arena. It is composed of five items assessing global life satisfaction, using a Likert type response format. The aim of this paper is to validate the Portuguese version of the SWLS via confirmatory factor analysis, with a sample of 1,003 elderly from Angola. Reliability, factorial and criterial validity estimates are presented. Overall, the results shown that the scale had an adequate one-factor confirmatory solution, satisfying reliability indices, and adequate criterion-related validity when assessed in a sample of Angolan elderly. The discussion relates the results with existing literature and posits the contributions of the paper: firstly, it offers the researchers on life satisfaction in Portuguese-speaking contexts a brief, self-rated measure of satisfaction with life that has sound psychometric properties, validity, and reliability; secondly, it is the first confirmatory validation of the scale in Portuguese.     

Cross-Cultural Adaptation,Validity and Reliability of the Escala Pessoal de Resultados

The present article aims to examine the validity and reliability of the Portuguese version of Personal Outcomes Scale the Escala Pessoal de Resultados (EPR). This scale represents an instrument to measure the quality of life (QOL) in people with intellectual disabilities (ID). The study was initiated with the application of international guidelines in cross-cultural adaptation, culminating with an evaluation of 10 experts for the quantitative evidence of the content validity. All EPR’s items were considered relevant and there was a moderated agreement (k > .40) among the experts in the calculation of Cohen’s kappa, finding some coefficients’ that are considered as an excellent agreement (k > .75). In test field, our sample comprised 335 adults with ID on level of intermittent and limited support needs, even as the respective proxies. The scale showed an excellent internal consistency (α = .94). EPR’s construct validity indexes are also reported and discussed. The study provides EPR as a valid instrument for assess the QOL in ID field, and the scale seems to be useful for improvement of Portuguese rehabilitation practices and services.
