Testing Measurement Invariance and Comparing Latent Factor Means Within a Confirmatory Factor Analysis Framework (2011, methodology): “…Management, Δχ2 (5) = 119.38, p < .001, and Instructional Management, Δχ2 (5) = 58.91, p < .001, scales, thus the nonlinear SEM reliability estimates (Green & Yang 2009; Yang & Green, 2011) of .79 and .78 were computed for the Behavior Management and Instructional Management scales, respectively.”
Why Ordinal Variables Can (Almost) Always Be Treated as Continuous Variables: Clarifying Assumptions of Robust Continuous and Ordinal Factor Analysis Estimation Methods (2020, background): “Moreover, we generally question the strong preference of a model-based assessment of reliability from a factor analysis (e.g., McNeish, 2018; Sijtsma, 2009; Yang and Green, 2011) compared to designbased reliability measures (i.”
Construct Validation in Social and Personality Research (2017, methodology): “We referred readers to Graham (2006), Sijtsma, (2009), and Yang and Green (2011) for details on how to test these assumptions in classical test theory and structural equation modeling framework.”
Making Reliability Reliable (2016, background): “…studies such as Cortina (1993) and Schmitt (1996) offered influential lessons on alpha for organizational researchers, it is still commonly misconceived and widely misused (Cho & Kim, 2015; Dunn, Baguley, & Brunsden, 2013; Green & Yang, 2009a; Raykov, 2012; Sijtsma, 2009a; Yang & Green, 2011).”
A journey around alpha and omega to estimate internal consistency reliability (2017, methodology): “Omega hierarchical is a more general specification for Equation 5 as is explained by Gu et al. (2013) for quantitative data and by Yang and Green (2011) for ordinal data.”
Best Alternatives to Cronbach's Alpha Reliability in Realistic Conditions: Congeneric and Asymmetrical Measurements (2016, background): “In this more realistic condition therefore (Green and Yang, 2009a; Yang and Green, 2011), α becomes a negatively biased reliability estimator (Graham, 2006; Sijtsma, 2009; Cho and Kim, 2015) and ω is always preferable to α (Dunn et al., 2014).”
Volunteer Management (2016, methodology): “These components consist of only a few items, and as the measure for reliability is dependent on the number of items (Yanyun Yang & Green, 2011), it is reasonable to assume that further development of the scale might deliver components that are more consistent.”
A Practical Measure of Student Motivation (2015, methodology): “Reliability estimates were calculated using coefficient omega, which is a more accurate index of internal consistency than alpha (Yang & Green, 2011).”
“My Questionnaire is Too Long!” The assessments of motivational-affective constructs with three-item and single-item measures (2014, background): “Com mon method variance due to similarly worded items or other compounded systematic errors produced by redundant items (e.g., because of socially desirable responding; Robins, Hendin, & Trzesniewski, 2001) can lead to artificially high reliability estimates (Yang & Green, 2011).”
From alpha to omega: a practical solution to the pervasive problem of internal consistency estimation. (2014, unknown): “For example, many researchers advocate the use of structural equation modelling (SEM) as the most robust tool to assess a test’s reliability, mainly, because it allows one to specify and compare different models of reliability (e.g., Graham, 2006; Miller, 1995; Yang & Green, 2011).”
