Investigating the Substantive Aspect of Construct Validity for the Satisfaction with Life Scale Adapted for Children: A Focus on Cognitive Processes

The objective of this study was to investigate the substantive aspect of construct validity of the Satisfaction with Life Scale adapted for Children (SWLS-C; Gadermann et al. in Soc Indic Res 96:229–247, 2010). Specifically, the study examined the cognitive processes of children when responding to the items of the SWLS-C to find out how they interpret and respond to the items. Think-aloud protocol interviews were conducted with 55 students in grades 4–7 (58% girls, mean age of 11 years, ranging from 8.8 to 12.8 years) and content analysis was used to analyze the data. The findings indicate that most children had no difficulty in understanding the items, and used mainly two strategies for responding to the items: (1) an absolute strategy, in which children used absolute statements to indicate the presence or absence of something that is important for their judgment of their satisfaction with life, and (2) a relative strategy, in which children used relative or comparative statements. In the absolute statements, children primarily referred to social relationships, personal characteristics, time use, and possessions. In the relative statements, the children primarily compared what they have to (a) what they want (b) what they had in the past, (c) what other people have, and (d) what they feel they need. Furthermore, most children considered it important that information on their life satisfaction is obtained. The results are discussed with regard to multiple discrepancies theory (Michalos in Soc Indic Res 16:347–413, 1985) and previous empirical findings. The results provide insights into children’s cognitive processes when responding to items on life satisfaction and provide validity evidence that the SWLS-C is an appropriate measure to assess life satisfaction in children of this age.     

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.     

The Hedonic and Eudaimonic Validity of the Orientations to Happiness Scale

The orientations to happiness scale (OTH) was designed to measure three routes to happiness: pleasure (hedonia), meaning (eudaimonia) and engagement (flow). Past research utilising the scale suggests that all orientations predict life satisfaction, with meaning and engagement the stronger predictors relative to pleasure. However, these findings are inconsistent with other research; one plausible explanation being that the OTH scale lacks validity. This was tested by having participants (N = 107) complete the OTH scale and the Satisfaction with Life scale, prior to completing an online diary reporting actual instances of hedonic and eudaimonic behaviour. Although meaning predicted eudaimonic behaviour, the pleasure orientation was unrelated to hedonic behaviour. Further, hedonic behaviour was more strongly related to life satisfaction than eudaimonic behaviour; inconsistent with OTH scale results. These findings challenge the validity of the OTH scale, and subsequently bring into question those conclusions drawn from past research utilising the OTH scale.     

Reliability and Validity of Japanese Versions of the Flourishing Scale and the Scale of Positive and Negative Experience

The demographic aging of the older population itself has turned out as an issue of great scope, accumulating a large amount of research in recent years. In this context, the prediction or explanation is of much interest. However, little research has studied this prediction when some factors, such as age, gender, and perceived health are controlled, and also few studies have compared these effects in young old and oldest old populations. Thus, the purpose of this study is to test, in a multivariate context, the predictive effects of variables measuring social support, dependence/active perceptions, and generativity on satisfaction with life, while controlling for age, marital status, educational level, gender, and perceived health; examining young old and oldest old similitudes and differences in a little studied population, the Angolan elderly. The sample was formed by 1,003 participants, 737 were young old and 266 were oldest old. To test for the effects, a hierarchical regression was built up, in which age and predictor’s interactions were included. Results provide support for some differences in the pattern of relationships hold by young old and oldest old, with social support emerging as the major predictor of life satisfaction during the old age.     

Report on the Construct Validity of the Temporal Satisfaction With Life Scale

This study evaluated the factorial and convergent validity of theTemporal Satisfaction With Life Scale (TSWLS; Pavot, Diener andSuh, 1998), which was designed to measure past, present, andfuture life satisfaction. A sample of psychology undergraduates(N = 223) was administered a questionnaire containing the TSWLSand a global measure of past, present, and future subjectivewell-being (SWB), the Self-Anchoring Striving Scale (SASS;Kilpatrick and Cantril, 1960). Results of covariance structureanalyses supported a 3-factor model (past, present, and futurelife satisfaction as distinct, yet correlated, factors) for theTSWLS, demonstrated that item responding was only slightlycontaminated by an acquiescence bias, and showed that each of thepast, present, and future dimensions of the TSWLS was moststrongly related to its corresponding global SWB rating on theSASS. Theoretical and practical implications are discussed.     

Factorial Validity and Invariance of the Rosenberg Self-Esteem Scale Among Portuguese Youngsters

The purpose of the present study was to examine the reliability, factorial validity and measurement invariance (across gender, age and physical activity participation) of a Portuguese version of the Rosenberg Self-Esteem Scale (RSES). The sample consisted of 1,763 Portuguese youngsters (731 male and 1,032 female) with ages between 15 and 20 years. Reliability estimate for the one-factor solution was .845, although some proposed RSES’s underlying dimensions were lower than .70. Confirmatory factor analysis revealed that the best-fitting model was a single self-esteem factor, plus simultaneous correlated uniqueness for positively and negatively worded items. Multigroup analysis supported measurement invariance across age and physical activity participation, and partial metric invariance across gender, as three items failed to show metric equivalence. These results provide evidence that RSES has excellent psychometric properties and it is a valid self-esteem measure to be used among Portuguese youngsters.     

How small can the difference among competitors be for coexistence to occur

Closely related competitors comprising ofEscherichia coli strains having the same metabolic system and differing only with a few bases on the glutamine synthetase gene in the plasmid pKGN were previously shown to coexist in a chemostat. The differences among these closely related competitors can be considered large enough to allow coexistence as the level of enzyme activity is different. To bring the difference among competitors to the slightest possible, the mutation was introduced on the noncoding region of the plasmid pKGN harbored in the wild-type strain (strain W). The new strain, strain W’, carries the plasmid pKGN’ with a 4-base insertion at theHind III site in the polycloning site of pKGN. As the noncoding region is a nucleotide segment that is not translated into amino acids, the relatedness between strains W and W’ is the closest possible from the genetic point of view. Interestingly, though both strains are almost identical, they can coexist stably in a chemostat irrespective of the initial population size. These experimental results suggest that in the natural ecosystem, no matter how akin competitors are, coexistence is not impossible.     

How development programs can affect fertility: the case of Bangladesh

Improving living standards and increasing productivity in developing countries may result in fertility reduction. In Bangladesh, government policy stresses rural development and fertility reduction. Programs that raise women's status reduce fertility. Educational level is inversely correlated to childbearing. Women aged 25-29 with a Secondary School Certificate have 2.4 children, versus 4.0 for those with no education. Employment also decreases fertility. Thus, improving the educational and employment status of women could have major effects on fertility. Studying the Bangladesh Rural Social Services program revealed that community organization efforts and self-help programs for economic and social improvement also decrease fertility. Rural electrification programs, which have been emphasized in development planning, contribute to changing attitudes and behavior of residents of these regions. In addition to electrification, improved transportation and communications should enhance the spread of information to rural areas. Agricultural development programs, such as the Comilla development program, have not affected fertility. This is attributed to the concentration of benefits to a few farms, with the majority becoming poorer. Unless agricultural development benefits are widely distributed, there will probably be little effect on fertility. Thus, the development programs most likely to affect fertility are those which emphasize female education and employment, open rural areas to information and ideas, and are open to a whole community.     

How to Reduce the Impact of Equivalence Scales on Poverty Measurement: Evidence from Turkey

The main aim of the paper is to contribute to the poverty measurement literature by demonstrating a method to reduce the impact of equivalence scales in poverty measurement. This is accomplished by choosing the most appropriate reference household type. The results showed that one adult household is certainly not suitable for being the reference household type. When one adult household is set as the reference, in the range of no equivalence scale and per capita equivalence scale, poverty head count ratio changes from 1 to 48 %, showing the huge effect of the equivalence scale choice. Also the analyses at household size level showed that one adult household type is not convenient to be the reference household type. On the other hand, no clear distinction could be made between central household types, but the importance of choosing a household type close to the center was demonstrated for Turkish data.     

Reliability and Validity of the Personal Social Capital Scale 16 and Personal Social Capital Scale 8: Two Short Instruments for Survey Studies

Rapid developments in social capital and health research require short instruments for large-scale survey studies. The Personal Social Capital Scale (PSCS) is a theory-based and empirically tested instrument with reliability and validity established in the US and China, but it is too long for large-scale survey research. In this study, we described two short versions of the instrument: the PSCS-16 and PSCS-8. The two short scales were evaluated with survey data collected among an adult sample (N = 259) in China. The sample consisted of rural-to-urban migrants and non-migrant rural and urban residents. Cronbach’s alpha coefficients were .90 for the PSCS-18 and .83 for the PSCS-8. Both short instruments satisfactorily fit a two-factor model comprising the bonding capital and bridging capital subscales. The two short scales were highly correlated with the original PSCS (r = .95 for the PSCS-18 and .93 for the PSCS-8 respectively, p < .001 for both); significantly distinguished the migrant subsample from the two non-migrant subsamples; and significantly predicted social capital investment and stress level. In conclusion, the two short instruments PSCS-16 and PSCS-8 were reliable and valid, and can be used in large-scale survey studies to assess personally owned social capital. Further research is needed to replicate their reliability and validity in different cultural settings and to establish the test–retest reliability.     

The Predictive Validity of Subjective Mortality Expectations: Evidence From the Health and Retirement Study

Several recent studies suggest that individual subjective survival forecasts are powerful predictors of both mortality and behavior. Using 15 years of longitudinal data from the Health and Retirement Study, I present an alternative view. Across a wide range of ages, predictions of in-sample mortality rates based on subjective forecasts are substantially less accurate than predictions based on population life tables. Subjective forecasts also fail to capture fundamental properties of senescence, including increases in yearly mortality rates with age. To shed light on the mechanisms underlying these biases, I develop and estimate a latent-factor model of how individuals form subjective forecasts. The estimates of this model’s parameters imply that these forecasts incorporate several important sources of measurement error that arguably swamp the useful information they convey.     

A Validity and Reliability Study of the Multidimensional Trust in Health-Care Systems Scale in a Turkish Patient Population

The importance of trust within health care is widely acknowledged. Measuring patients’ trust in health care systems may contribute to plans for the financing, delivery, and outcomes of health services. Although many scales are available to measure patient trust, less attention has been paid to the multidimensional nature of trust in health care systems. The purpose of this methodological study was to adapt the Multidimensional Trust in Health-Care Systems Scale into Turkish and to evaluate its psychometric properties for a Turkish patient population. The scale was adapted into Turkish through a translation and back-translation process. The content validity of the scale was assessed using expert approval. The psychometric properties of the scale were investigated by collecting data from 232 hospitalised patients in Ankara during theperiod of 1 January–30 December 2010. An exploratory factor analysis identified that the eigenvalues for the three factors of the scale were 7.30, 2.61, and 1.21; these three factors explained 65 % of the variance. A confirmatory factor analysis indicated a sufficient model fit for the construct validity of the scale. Cronbach’s α for the total scale was 0.87, as well as 0.91, 0.82, and 0.61 for the three subscales; the Spearman-Brown split half reliability coefficient was 0.67. Despite the low internal consistency of the subscale 3, evidence from this study supports the validity and reliability of the Multidimensional Trust in Health-Care Systems Scale. This instrument can be used to measure multiple aspects of trust in the health care system; however, as trust is a contextual phenomenon, further work is needed to test the psychometric properties of this scale both in Turkish and different cultures.     

Application and Testing the Reliability and Validity of a Modified Version of Herek's Attitudes Toward Lesbians and Gay Men Scale in China

The present study was the first attempt to test the reliability and validity of Herek's Attitudes Toward Lesbians and Gay Men Scale (ATLG; Herek, 1988 Herek, G. M. 1988. Heterosexuals' attitudes toward lesbians and gay men: Correlatesand gender differences. The Journal of Sex Research, 25(4): 451–477. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) in the Chinese population. Participants (n = 2,391 for the field trials and n = 200 for test–retest reliability) were asked to complete the translated, slightly modified version of the ATLG. The resulting ATLG has a two-dimensional factor structure as well as good validity and reliability in the Chinese culture. ATLG scores followed distinct patterns according sex and level of education that were consistent with previous studies in other populations. The significance of these findings in Chinese culture is discussed.

Using Perceived Health to Test the Construct-related Validity of Global Quality of Life

Quality of life (QOL) is considered as aglobal, yet unidimensional, subjectiveassessment of one's satisfaction with life. Weexamine the construct validity of the availableindicators of global QOL by constructing acausal model in which QOL is viewed as causallyresponding to several dimensions of perceivedhealth. Global QOL is measured with fiveindicators derived from the literature, andperceived health is measured by eightdimensions of the SF-36 Health Survey. Thestructural equation model describes the QOL andperceived health assessments of 306 coronaryartery bypass graft (CABG) patients andprovides a stringent test of theunidimensionality of the global QOL indicators.The evidence regarding QOL is worrisome, butnot devastating. The acceptable model fit wasachieved by introducing direct effects leadingfrom the General Health Perceptions concept totwo of the five indicators of global QOL. Thissuggests that there are some mechanisms thatinfluence these indicators without firstaltering QOL, or that these indicators are notresponding in unison to QOL. Furthermore, theFaces QOL indicator required measurement errorcorrelations to two of the perceived healthindicators. This also suggests that there aremechanisms beyond pure QOL that act upon thisindicator. But the problematic effects anderror correlations are modest, so the evidenceagainst these indicators is not particularlystrong. Overall, the Self-Anchoring StrivingScale (SASS) indicator and the Life-as-a -Wholeindicator (from Multiple Discrepancies Theory)seem to be the cleanest indicators of globalQOL. General health perceptions and perceivedmental health both influenced global QOL, whilethe other six health perception concepts had noconsistent impact on global QOL.

Assessing Validity and Application Scope of the Intrinsic Estimator Approach to the Age-Period-Cohort Problem

In many different fields, social scientists desire to understand temporal variation associated with age, time period, and cohort membership. Among methods proposed to address the identification problem in age-period-cohort analysis, the intrinsic estimator (IE) is reputed to impose few assumptions and to yield good estimates of the independent effects of age, period, and cohort groups. This article assesses the validity and application scope of IE theoretically and illustrates its properties with simulations. It shows that IE implicitly assumes a constraint on the linear age, period, and cohort effects. This constraint not only depends on the number of age, period, and cohort categories but also has nontrivial implications for estimation. Because this assumption is extremely difficult, if not impossible, to verify in empirical research, IE cannot and should not be used to estimate age, period, and cohort effects.
