Subscore added value analyses assume invariance across test taking populations; however, this assumption may be untenable in practice as differential subdomain relationships may be present among subgroups. The purpose of this simulation study was to understand the conditions associated with subscore added value noninvariance when manipulating: (a) subdomain test length, (b) differences in subgroup mean ability, and (c) subgroup differences in intersubdomain correlations. Results demonstrated that subscore added value was noninvariant for 24–100% of replications (depending on subdomain test length) when the subgroup difference in intersubdomain correlation was equal to .30. To examine if this condition was met in practice, applied invariance analyses of three operational testing programs were conducted. Across these datasets, noninvariant subscore added value was present for some subdomains across sex and ethnic subgroups. Overall, these results indicate that subscore added value noninvariance is largely driven by differential intersubdomain correlations among subgroups, which may be present in some operational testing programs. 相似文献

In the present study, we examined the dimensionality and the measurement invariance of the Multicultural Ideology Scale (MCI), and mean differences across different cultural groups within the multilingual, multicultural context of Luxembourg. Luxembourg is a unique context to study attitudes towards diversity because 47.4 % of the citizens are non-nationals (i.e. economic migrants, sojourners, refugees) and minority and majority are increasingly difficult to define. Our sample included 1488 participants from diverse ethnic backgrounds who completed the survey in German, French or English. In contrast to previous findings, our analyses on responses to the MCI scale produced a two-dimensional structure, distinguishing between positive and negative attitudes towards multiculturalism. The factor structure was partially invariant across ethnocultural groups: Configural and metric invariance were established across natives and non-natives and different language versions. Scalar invariance was only established across gender groups. Natives and male participants reported the most negative attitudes towards multiculturalism. We discuss the importance of assessing measurement invariance and provide recommendations to improve the assessment of psychological multiculturalism. 相似文献

Lack of motivation, or amotiation, is emerging as a critical issue in high school physical education. The Amotivation Inventory-Physical Education (Shen, Winger, Li, Sun, & Rukavina, 2010) was developed to measure the multidimensional nature of amotivation construct in physical education. This study was designed to examine the consistency of the metric properties of Amotivation Inventory-Physical Education scores by evaluating their factorial structure for invariance across gender in a sample of 985 urban inner-city high school adolescents. Latent mean invariance was also tested. Results revealed that constraining factor loadings and intercepts in sequential configural, metric, and scalar invariances had no meaningful impact on model fit. However, gender might play a role in the magnitude of factor scores. Findings suggest that the four-factor structure of the Amotivation Inventory-Physical Education is a satisfactory representation of motivational deficits for urban inner-city adolescents and provide significant validity evidence for the scale scores in urban high school settings. 相似文献

Although empirical research in academic areas provides support for both a 3-factor as well as a 4-factor achievement goal model, both models were proposed and tested with a collegiate sample. Little is known about the generalizability of either model with high school level samples. This study was designed to examine whether the 3-factor model (Mastery Goals, Performance-Approach Goals, and Performance-Avoidance Goals) or the 4-factor model (Mastery-Approach Goals, Mastery-Avoidance Goals, Performance-Approach Goals, and Performance-Avoidance Goals) is appropriate in high school physical education settings. The factorial validity of the models and internal consistency reliability were tested with confirmatory factor analysis, invariance testing, and tests of internal consistency across 2 samples. The results reveal that the items from the 4-factor achievement goal model can produce internally consistent and valid scores for high school students in physical education settings; the 4-factor model provides a better fit to the data than the 3-factor model. The multistep invariance analysis, however, reveals only metric invariance across 2 school samples. 相似文献

Expectancy-value researchers have described the components of subjective task value in multiple ways, leading to multiple competing structural representations of subjective task value data. The purpose of this study was to examine these competing multidimensional factor structures by comparing correlated factor, hierarchical, and bifactor representations of both confirmatory factor analysis and exploratory structural equation modeling (ESEM) models across three theoretical conceptualizations of subjective task value. Results indicate that, in an undergraduate life science learning context (n = 334), the best representation for subjective task value data was a bifactor ESEM model that allowed for the disentangling of general and specific variance of general subjective task value, specific value beliefs, and specific costs. Full measurement invariance of the retained structure across continuing generation and first-generation students was found, and no differential item functioning was found across gender. General subjective task value and specific opportunity cost significantly and positively predicted achievement and specific utility value significantly and negatively predicted achievement, providing support for the criterion-related validity of the general and specific factors for predicting achievement outcomes. 相似文献

A challenge using the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) in studying reading growth is that reading skills children exhibit change by age. In order to study growth using changing subscales, it is necessary to examine measurement invariance and measurement structure underlying the different subscales. The purpose of this paper is to examine the measurement structure of the DIBELS subscales, particular measurement invariance. The results indicate that the DIBELS subscales do not seem to have metric invariance but they do share a common factor over time, suggesting that the same construct of reading skills were measured but they manifested in the different fashion over time. 相似文献

We present a multigroup multilevel confirmatory factor analysis (CFA) model and a procedure for testing multilevel factorial invariance in n-level structural equation modeling (nSEM). Multigroup multilevel CFA introduces a complexity when the group membership at the lower level intersects the clustered structure, because the observations in different groups but in the same cluster are not independent of one another. nSEM provides a framework in which the multigroup multilevel data structure is represented with the dependency between groups at the lower level properly taken into account. The procedure for testing multilevel factorial invariance is illustrated with an empirical example using an R package xxm2. 相似文献

Using data from 48 countries, this study investigated the factorial structure and tested the cross-cultural invariance of the PIRLS 2011 reading self-concept scale and its relationships with reading achievement. The study showed that a two-factorial structure of the self-concept scale in reading had the best fit with the data. Configural invariance and metric invariance were achieved, scalar invariance was not. The two dimensions ‘Perception of competence’ and ‘Perception of difficulty’ showed robust within-country correlations with reading achievement, especially the second one. At the country level, the ‘Perception of competence’ was negatively related with reading, illustrating the attitudes-achievement paradox: countries in which students on average reported a more positive self-concept performed lower. On the contrary, for the ‘Perception of difficulty’, the sign of the correlation remained the same at the within-country and at the country level. 相似文献
