While morale among the elderly has been widely and extensively studied, results are varied and at times conflicting. Hence, the purpose of this study is to explore the factors affecting elderly morale of a select group of Filipinos in a community setting. A 64-item questionnaire was utilized to survey 323 Filipinos aged 60 and above residing in the National Capital Region of the Philippines in May 2013. Respondents completed a robotfoto, a checklist of chronic illnesses, and measures of the social support, functional ability, geriatric depression, and morale. Structural equation modeling was used to test the hypothesized model. Two competing models emerged in the study. Model 1 followed causal relationships indicated in the hypothesized model while model 2 considered modification indices that surfaced more acceptable fit indices (X2/df = 1.414, GFI [goodness of fit index] = 0.988, CFI [comparative fit index] = 0.987, RMSEA [root mean square error of approximation] = 0.036). Chronic illness, social support, and depression were found to be major predictors of morale. Number of chronic illnesses and depression were also found to have a negative relationship with functional ability, and chronic illness and social support were negatively correlated. Findings can assist health professionals such as nurses to identify the factors that shape elderly morale vis-a-vis the use of effective strategies that promote the well-being of elderly people. The emerging model can serve as reference to assess the effectiveness of quality of care rendered as manifested by morale.  相似文献

Students' perceptions of the education environment influence their learning. Ever since the major medical curriculum reform, anatomy education has undergone several changes in terms of its curriculum, teaching modalities, learning resources, and assessment methods. By measuring students' perceptions concerning anatomy education environment, valuable information can be obtained to facilitate improvements in teaching and learning. Hence, it is important to use a valid inventory that specifically measures attributes of the anatomy education environment. In this study, a new 11‐factor, 132‐items Anatomy Education Environment Measurement Inventory (AEEMI) was developed using Delphi technique and was validated in a Malaysian public medical school. The inventory was found to have satisfactory content evidence (scale‐level content validity index [total] = 0.646); good response process evidence (scale‐level face validity index [total] = 0.867); and acceptable to high internal consistency, with the Raykov composite reliability estimates of the six factors are in the range of 0.604–0.876. The best fit model of the AEEMI is achieved with six domains and 25 items (X2 = 415.67, P < 0.001, ChiSq/df = 1.63, RMSEA = 0.045, GFI = 0.905, CFI = 0.937, NFI = 0.854, TLI = 0.926). Hence, AEEMI was proven to have good psychometric properties, and thus could be used to measure the anatomy education environment in Malaysia. A concerted collaboration should be initiated toward developing a valid universal tool that, using the methods outlined in this study, measures the anatomy education environment across different institutions and countries.

The Classroom Appraisal of Resources and Demands (CARD) was designed to evaluate teacher stress based on subjective evaluations of classroom demands and resources. However, the CARD has been mostly utilized in western countries. The aim of the current study was to provide aspects of the validity of responses to a Chinese version of the CARD that considers Chinese teachers’ unique vocational conditions in the classroom. A sample of 580 Chinese elementary school teachers (510 female teachers and 70 male teachers) were asked to respond to the Chinese version of the CARD. Confirmatory factor analyses showed that the data fit the theoretical model very well (e.g., CFI: .982; NFI: .977; GFI: .968; SRMR: .028; RMSEA: .075; where CFI is comparative fit index, NFI is normed fit index, GFI is goodness of fit, SRMR is standardized root mean square residual, RMSEA is root mean square error of approximation), thus providing evidence of construct validity. Latent constructs of the Chinese version of the CARD were also found to be significantly associated with other measures that are related to teacher stress such as self‐efficacy, job satisfaction, personal habits to deal with stress, and intention to leave their current job.  相似文献

Research Findings: Empathy, or the ability to understand what others are thinking or feeling, can be observed in early developmental stages. The purpose of this study was to validate the Spanish version of the Empathy Questionnaire (EmQue) and examine its longitudinal measurement invariance (LMI) at 2 time points. Parents of 103 children completed the EmQue when their children were 3 (M = 41.76) and 4 (M = 51.65) years old. Confirmatory factor analyses revealed that Grazzani, Ornaghi, Pepe, Brazzelli and Rieffe’s (2016) 3-factor model of emotional contagion (EC), attention to others’ feelings, and prosocial actions (PA) presented the best fit indices at both time points (Time 1: CFI = .931, TLI = .914, and RMSEA = .070; Time 2: CFI = .941, TLI = .935, and RMSEA = .064). Moreover, preliminary evidence was obtained for the LMI of this model. PA scores increased over time. Score reliability ranged from .60 (EC) to .83 (PA). Positive correlations were found between PA and emotional regulation at each time point and across time.Practice or Policy: The great relevance of empathy and prosocial behavior in academic achievement and psychological adjustment justifies the development of reliable instruments to evaluate these constructs from early ages.  相似文献

Abstract

An increasing number of K–12 schools have adopted blended learning approaches. Current empirical research has been sparse regarding preparing teachers for blended teaching, including the skills they must develop to teach in blended contexts. This research is focused on that weakness, with the purposes of systematically identifying the skills needed for teaching in a blended learning context and of developing and testing an instrument that can be used to determine individual and school-wide readiness for blended teaching. In this study we present a measurement model used to develop items for measuring K–12 blended learning readiness. Specifically the instrument contained the following top-level areas: (a) foundational knowledge, skills, and dispositions, (b) instructional planning, (c) instructional methods and strategies, (d) assessment and evaluation, and (e) management. Each top-level construct also had two to four subconstructs. Through confirmatory factor analysis using survey responses from 2,290?K–12 teachers we found that the data met all four fit statistics cutoffs set forth in the literature (root mean square error of approximation [RMSEA]= 0.041, comparative fit index [CFI]?=?0.926, Tucker–Lewis index [TLI]?=?0.923, standardized root mean square residual [SRMR]?=?0.041, X2?=?978.934, df?=?1992).  相似文献

The central purposes of this study were to review the development and evolution of the Scientific Attitude Inventory (SAI) and then reevaluate the psychometric properties of the revised form of the SAI, the Scientific Attitude Inventory II (SAI‐II). The SAI‐II was administered to a convenience sample of 543 middle and high school students from five teachers in four schools in four school districts in San Antonio, Texas, at the beginning of the 2004–2005 school year. Confirmatory factor analysis on the full data set failed to support the existence of a 12‐factor structure (as proposed by the scale developers) or a one‐factor structure. The data were then randomly divided into exploratory [exploratory factor analysis (EFA)] validation and confirmatory [confirmatory factor analysis (CFA)] cross‐validation sets. Exploratory and confirmatory models yielded a three‐factor solution that did not fit the data well [χ2 (321) = 646, p < .001; RMSEA = .061 (.90 CI = .054–.068); and CFI = .81]. The three factors were labeled “Science is About Understanding and Explaining” (13 items), “Science is Rigid” (6 items), and “I Want to Be a Scientist” (8 items). The α‐coefficients for these three factors ranged from 0.59 to 0.85. Whether these identified subscales are valid will require independent investigation. In this sample, and consistent with prior publications, the SAI‐II in its current form did not have satisfactory psychometric properties and cannot be recommended for further use. © 2008 Wiley Periodicals, Inc.

The purpose of current study was to explore psychometric properties of the Turkish version of the Balanced Index of Psychological Mindedness (BIPM). Studies regarding psychological mindedness (PM) are still limited in Turkey; and there are few valid instruments to measure PM. The Turkish version of the BIPM and the 20-Item Toronto Alexithymia Scale (TAS) was administered to 654 voluntary undergraduate students. Confirmatory factor analysis indicated a good fit for the model including two subscales (interest and ability dimensions of PM) with a total of 14 items (x2/df?=?3.11, p?<?.001, RMSEA?=?0.060, S-RMR?=?0.059, GFI?=?0.95, AGFI?=?.0.93, CFI?=?0.94). McDonald’s Omega (ω) for scores on the overall scale was .85, .73 for scores on the Interest Subscale and .76 for scores on the Insight Subscale. Test–retest reliability coefficients were found as .61 for the scores on the BIPM total score, .55 for scores on the Interest subscale and .56 for scores on the Insight subscale (p?<?.01). As expected, the BIPM total scale score were negatively correlated with TAS total score (r?=?-.59).

Research Findings: The present study was designed to examine the factorial validity of the Student–Teacher Relationship Scale–Short Form (STRS-SF; R. C. Pianta, 2001 Hamre, B. K. and Pianta, R. C. 2001. Early teacher-child relationships and the trajectory of children's school outcomes through eighth grade.. Child Development, 72: 625–638. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and its invariance across gender in the Greek educational context. The STRS-SF comprises 15 items that measure 2 dimensions of teacher–child relationships: Closeness and Conflict. Fifty-six kindergarten teachers completed the STRS-SF about their students (n = 336). A 2-factor model with correlated latent factors was postulated and tested. Confirmatory factor analysis procedures showed marginal fit to the data (comparative fit index [CFI] = .902, root mean square error of approximation [RMSEA] = .066). The fit of the model was further improved by adding 2 error covariances (CFI = .931, RMSEA = .056). Cronbach's alpha coefficient showed adequate internal consistency for Closeness (α = .72) and Conflict (α = .82). In addition, there was a moderate negative association between the 2 subscales (r = ?.38). Examination of STRS-SF invariance showed that it was manifested in the same way across gender. Practice or Policy: The findings of the present study, which was conducted in a cultural context different from the one in which the STRS-SF was developed, seem to support the instrument's factorial validity and equivalence across gender.  相似文献

Conventional null hypothesis testing (NHT) is a very important tool if the ultimate goal is to find a difference or to reject a model. However, the purpose of structural equation modeling (SEM) is to identify a model and use it to account for the relationship among substantive variables. With the setup of NHT, a nonsignificant test statistic does not necessarily imply that the model is correctly specified or the size of misspecification is properly controlled. To overcome this problem, this article proposes to replace NHT by equivalence testing, the goal of which is to endorse a model under a null hypothesis rather than to reject it. Differences and similarities between equivalence testing and NHT are discussed, and new “T-size” terminology is introduced to convey the goodness of the current model under equivalence testing. Adjusted cutoff values of root mean square error of approximation (RMSEA) and comparative fit index (CFI) corresponding to those conventionally used in the literature are obtained to facilitate the understanding of T-size RMSEA and CFI. The single most notable property of equivalence testing is that it allows a researcher to confidently claim that the size of misspecification in the current model is below the T-size RMSEA or CFI, which gives SEM a desirable property to be a scientific methodology. R code for conducting equivalence testing is provided in an appendix.  相似文献

This article compares two structural equation modeling fit indexes—Bentler's ( 1990; Bentler & Bonett, 1980) Confirmatory Fit Index (CFI) and Steiger and Lind's (1980; Browne & Cudeck, 1993) Root Mean Square Error of Approximation (RMSEA). These two fit indexes are both conceptually linked to the noncentral chi‐square distribution, but CFI has seen much wider use in applied research, whereas RMSEA has only recently been gaining attention. The article suggests that use of CFI is problematic because of its baseline model. CFI seems to be appropriate in more exploratory contexts, whereas RMSEA is appropriate in more confirmatory contexts. On the other hand, CFI does have an established parsimony adjustment, although the adjustment included in RMSEA may be inadequate.  相似文献

ObjectiveThe Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a self-report questionnaire that retrospectively provides screening for a history of childhood abuse and neglect, and which is widely used throughout the world. The current study aimed to examine the psychometric properties of the Chinese version of the CTQ-SF.MethodsParticipants included 3431 undergraduates from Hunan provinces and 234 depressive patients from psychological clinics. Confirmatory factor analysis was performed to examine how well the original five-factor model fit the data and the measurement equivalence of CTQ-SF across gender. Internal consistency was also evaluated.ResultsThe five-factor model achieved satisfactory fit (Undergraduate sample TLI = 0.925, CFI = 0.936, RMSEA = 0.034, SRMR = 0.046; depressive sample TLI = 0.912, CFI = 0.923, RMSEA = 0.044, SRMR = 0.062). Measurement invariance of the five-factor model across gender was supported fully assuming different degrees of invariance. The CTQ-SF also showed acceptable internal consistency and good stability.ConclusionThe current study provides that the Chinese version of the Childhood Trauma questionnaire-short form has good reliability and validity among Chinese undergraduates and depressive samples, which also indicates that the CTQ-SF is a good tool for child trauma assessment.  相似文献

Teachers' conceptions of assessment can be understood in terms of their agreement or disagreement with four purposes to which assessment may be put, specifically, (a) improvement of teaching and learning, (b) school accountability, (c) student accountability, or (d) treating assessment as irrelevant. A 50‐item Teachers' Conceptions of Assessment (COA‐III) questionnaire was completed by New Zealand primary school teachers and managers (n=525). The COA‐III, based on the four main purpose‐defined conceptions of assessment, was analysed with structural equation modelling and showed a close fit of the data to a hierarchical, multi‐dimensional model (χ2=3217.68; df=1162; RMSEA=.058; TLI=.967). On average, participants agreed with the improvement conceptions and the school accountability conception, while rejecting the view that assessment was irrelevant. However, respondents disagreed that assessment was for student accountability. Improvement, school, and student accountability conceptions were positively correlated. The irrelevance conception was inversely related to the improvement conception and not related to the system accountability conception. Surprisingly, no statistically significant differences were found in mean scale scores for each conception regardless of teacher (age, gender, role, assessment training, or assessment practices) or school (size, location, or socio‐economic status) variables. Implications for the use of the COA‐III for policy implementation and teacher professional development are discussed.  相似文献

Using data from the U.S. Department of Education's (2000) Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (ECLS-K), this study investigates the relationship between school efforts to engage parents, average socioeconomic status (SES) of families within a school, and kindergarteners' end-of-year reading and mathematics achievement. Drawing from Epstein's (2001 Epstein, J.L. 2001. School, family, and community partnerships: Preparing educators and improving schools, Boulder, CO: Westview Press.  [Google Scholar]) parent involvement framework, the 4 types of engagement efforts explored are intended to promote communication, parent volunteering, parent influence in school decision making, and parenting skills. We apply multilevel methods to explore the impact of schools' efforts to engage parents on student achievement. Our findings indicate certain types of school efforts to engage parents influence achievement. Depending on average school SES, efforts to promote volunteering has a differential impact on reading achievement, efforts to involve parents in school decision making has a differential impact on mathematics achievement, and efforts to increase communication and promote parenting skills have a differential impact on reading and mathematics achievement.  相似文献

This study examined a structural model of mathematics achievement among Druze 8th graders in Israel. The model integrates 2 psychosocial theories: goal theory and social learning theory. Variables in the model included gender, father's and mother's education, classroom mastery and performance goal orientation, mathematics self-efficacy and self-regulated learning, mastery and performance goals, and mathematics achievement. Data on learner and learning environment variables and achievement in mathematics were collected from 273 boys and girls. Results indicate appropriate fit of the model for the entire sample. Invariance analysis across gender indicated that only 2 of the 11 path coefficients, mother's education on mathematics achievement and classroom mastery goal orientation on self-regulation, were not invariant across gender. The same pattern of relationships accounted for different amounts of variance in mathematics achievement for boys and girls.  相似文献

Bootstrapping approximate fit indexes in structural equation modeling (SEM) is of great importance because most fit indexes do not have tractable analytic distributions. Model-based bootstrap, which has been proposed to obtain the distribution of the model chi-square statistic under the null hypothesis (Bollen & Stine, 1992), is not theoretically appropriate for obtaining confidence intervals (CIs) for fit indexes because it assumes the null is exactly true. On the other hand, naive bootstrap is not expected to work well for those fit indexes that are based on the chi-square statistic, such as the root mean square error of approximation (RMSEA) and the comparative fit index (CFI), because sample noncentrality is a biased estimate of the population noncentrality. In this article we argue that a recently proposed bootstrap approach due to Yuan, Hayashi, and Yanagihara (YHY; 2007) is ideal for bootstrapping fit indexes that are based on the chi-square. This method transforms the data so that the “parent” population has the population noncentrality parameter equal to the estimated noncentrality in the original sample. We conducted a simulation study to evaluate the performance of the YHY bootstrap and the naive bootstrap for 4 indexes: RMSEA, CFI, goodness-of-fit index (GFI), and standardized root mean square residual (SRMR). We found that for RMSEA and CFI, the CIs under the YHY bootstrap had relatively good coverage rates for all conditions, whereas the CIs under the naive bootstrap had very low coverage rates when the fitted model had large degrees of freedom. However, for GFI and SRMR, the CIs under both bootstrap methods had poor coverage rates in most conditions.  相似文献

Achievement in mathematics is inextricably linked to future career opportunities, and therefore, understanding those factors that influence achievement is important. This study sought to examine the relationships among attitude towards mathematics, ability and mathematical achievement. This examination was also supported by a focus on gender effects. By drawing on a sample of Australian secondary school students, it was demonstrated through the results of a multivariate analysis of variance that females were more likely to hold positive attitudes towards mathematics. In addition, the predictive capacity of prior achievement and attitudes towards mathematics on a nationally recognised secondary school mathematics examination was shown to be large (R 2  =  0.692). However, when these predictors were controlled, the influence of gender was non-significant. Moreover, a structural equation model was developed from the same measures and subsequent testing indicated that the model offered a reasonable fit of the data. The positing and testing of this model signifies growth in the Australian research literature by showing the contribution that ability (as measured by standardised test results in numeracy and literacy) and attitude towards mathematics play in explaining mathematical achievement in secondary school. The implications of these results for teachers, parents and other researchers are then considered.  相似文献

This study examines the interrelationships among components of parent involvement at schools and investigates their effects on school outcomes. The study used data collected during an evaluation of California's Early Childhood Education Program. Varinbles included socioeconomic status, the frequency of school-parent communications, parent awareness of school events, amount of parent involvement at the school, parent influence in school decision making, the nature of parent-teacher relationships, parent satisfaction with the school, and student achievement in reading and mathematics. The results indicated that there are positive effects associated with parent involvement at schools, and the interrelationships between the endogenous variables suggested ways in which such benefits may be maximized.  相似文献

This simulation study assesses the statistical performance of two mathematically equivalent parameterizations for multitrait–multimethod data with interchangeable raters—a multilevel confirmatory factor analysis (CFA) and a classical CFA parameterization. The sample sizes of targets and raters, the factorial structure of the trait factors, and rater missingness are varied. The classical CFA approach yields a high proportion of improper solutions under conditions with small sample sizes and indicator-specific trait factors. In general, trait factor related parameters are more sensitive to bias than other types of parameters. For multilevel CFAs, there is a drastic bias in fit statistics under conditions with unidimensional trait factors on the between level, where root mean square error of approximation (RMSEA) and χ2 distributions reveal a downward bias, whereas the between standardized root mean square residual is biased upwards. In contrast, RMSEA and χ2 for classical CFA models are severely upwardly biased in conditions with a high number of raters and a small number of targets.  相似文献

Using the Trends in International Mathematics and Science Study 2003 data, this study built mathematics achievement models of 8th graders in four countries: the USA, Russia, Singapore and South Africa. These 4 countries represent the full spectrum of mathematics achievement. In addition, they represent 4 continents, and they include 2 countries hugely influential in world events (the USA and Russia). In each country, students’ self-concept of ability in mathematics, mathematics values, perception of school, teachers’ and principals’ perceptions of school and other characteristics related to the classroom and school were incorporated to build an achievement model through hierarchical linear modelling. The final achievement models suggested that among student variables, self-concept of ability in mathematics had the highest relation to 8th graders’ mathematics achievement in all 4 countries. The relation between mathematics achievement and other student characteristics, along with the family, teacher and school variables, differed across the 4 countries. This suggests that self-concept of ability is a key variable for understanding achievement in high and low achieving countries and that other contextual variables vary in the magnitude of relations to mathematics achievement across countries.  相似文献
