Abstract:The few studies that have analyzed the factorial structure of early number skills have mainly used confirmatory factor analysis (CFA) and have yielded inconsistent results, since early numeracy is considered to be unidimensional, multidimensional or even underpinned by a general factor. Recently, the bifactor exploratory structural equation modeling (bifactor-ESEM)—which has been proposed as a way to overcome the shortcomings of both the CFA and the exploratory structural equation modeling (ESEM)—proved to be … Show more
“…This would be consistent with both the broad number sense factor proposed by Braeuning et al [18], and the multifactorial model proposed by Milburn et al [19] that includes a combined numeracy factor alongside distinct curriculum-aligned factors. This conceptualisation would also be consistent with suggestions that early numeracy is likely composed of both general and domain specific numerical factors [9,47]. Further research is needed both to more directly assess these hypotheses, and to assess whether or not the proposed core skills are more relevant to early numerical development than curriculum-aligned skills.…”

“…In addition to study aims and methods impacting the number of factors identified, different analysis techniques may suggest alternative ways of interpreting the structure of early numeracy. For instance, Dierendonck et al [47] investigated early numeracy using various modelling techniques, including CFA, bifactor-CFA, and bifactor exploratory structural equation modelling. A key distinction between these techniques is that bifactor models account for any shared communality of items through assuming the construct (e.g., early numeracy) is independently influenced by both a single general factor plus several domain specific factors.…”

“…The bootstrapping method was employed (Bootstrap = 5000), and the preliminary CFA results revealed that the four-factored model established in Study 2 was mildly supported (χ 2 = 666.36, df = 98, χ 2 /df = 6.80, CFI = 0.87, RMSEA = 0.10, SRMR = 0.09). The information obtained through the goodness-of-fit test indicated that ESEM was required to broaden our understanding of the organization of CWB ( Marsh et al, 2013 ; Fresno et al, 2020 ; Dierendonck et al, 2021 ; Gegenfurtner and Quesada-Pallarès, 2022 ).…”

“…Doing so can provide useful information for determining the latent optimal structure of CWB established in the literature ( Asparouhov and Muthén, 2009 ). CFA has been criticized for its overly simplistic, restrictive, and idealistic independent cluster model assumption ( Xiao et al, 2019 ; Dierendonck et al, 2021 ), which has led to CFA frequently failing to meet several standards of good measurement (e.g., goodness-of-fit, measurement invariance, and well-differentiated factors; Marsh et al, 2020 ). Because of this, ESEM has been proposed as a potential alternative.…”
As it is one decade since the establishment of Kidd’s model, an analysis of the career well-being (CWB) experienced by Eastern workers is both timely and necessary. To this end, we conducted a series of logical investigations of CWB in Taiwanese school teachers. Study 1 was conducted to conceptualize the main features of CWB (n = 135), and Study 2 was conducted using exploratory factor analysis to determine the validity of a four-factor measurement structure (n = 191). In Study 3, tests were completed to confirm the factor structure of the CWB (n = 533). Accordingly, we established a theory-based CWB measurement approach, and statistical analysis verified the convergent, divergent, and criterion validity of our CWB measurement model. Exploratory structural equation modeling rather than confirmatory factor analysis is recommended in discussions of CWB theory and practice in educational contexts. However, because our sample solely comprised Taiwanese teachers, our results are not generalizable to other occupations or cultures, even Eastern or Chinese-derived cultures. Implications for both theory and workplace counseling practice are presented.
“…Suppose we have assessed early numeracy (Dierendonck et al, 2021) with a standardized test in a sample consisting of 140 kindergarten children (the SAS listing to generate the data set and the listing for the analyses as well as the respective output are provided in Appendix B). The test encompasses three theoretical facets, each assessed by 10 items, namely counting, relations, and arithmetic.…”
Section: Specifying Irt Models With the Hbmirt Macromentioning
Item response theory (IRT) has evolved as a standard psychometric approach in recent years, in particular for test construction based on dichotomous (i.e., true/false) items. Unfortunately, large samples are typically needed for item refinement in unidimensional models and even more so in the multidimensional case. However, Bayesian IRT approaches with hierarchical priors have recently been shown to be promising for estimating even complex models in small samples. Still, it may be challenging for applied researchers to set up such IRT models in general purpose or specialized statistical computer programs. Therefore, we developed a user-friendly tool – a SAS macro called HBMIRT – that allows to estimate uni- and multidimensional IRT models with dichotomous items. We explain the capabilities and features of the macro and demonstrate the particular advantages of the implemented hierarchical priors in rather small samples over weakly informative priors and traditional maximum likelihood estimation with the help of a simulation study. The macro can also be used with the online version of SAS OnDemand for Academics that is freely accessible for academic researchers.
