The Assessment of Reliability Under Range Restriction (2012, background): “Therefore, a is simply a measure that indicates the degree to which a test is free from error (Cortina, 1993; Revelle & Zinbarg, 2009).”
Applying Bifactor Statistical Indices in the Evaluation of Psychological Measures (2016, methodology): “…researchers in achieving the preceding objectives: omega reliability coefficients (omega, omegaS, omegaH, omegaHS; McDonald, 1999; Reise, 2012; Revelle & Zinbarg, 2009; Zinbarg, Revelle, Yovel, & Li, 2005), factor determinacy (FD; Grice, 2001), construct replicability1 (H; Hancock & Mueller,…”
Cronbach’s Coefficient Alpha (2015, background): “His intention of stimulating debate was successfully realized; in 2009, four comments on his paper (Bentler, 2009; Green & Yang, 2009a, 2009b; Revelle & Zinbarg, 2009), as well as his rejoinder (Sijtsma, 2009b), were published in Psychometrika.”
The use of rating and Likert scales in Natural Language Generation human evaluation tasks: A review and some recommendations (2019, background): “A review of different measures of internal consistency can be found in Revelle and Zinbarg (2009) and McNeish (2018).”
Big data and predictive analytics for supply chain and organizational performance (2017, positive): “Both Cronbach's alpha and scale composite reliability (SCR) (Fornell & Larcker, 1981) were used (Henseler, Ringle, & Sinkovics, 2009; Revelle & Zinbarg, 2009).”
A Closed-Form Alternative for Estimating ω Reliability under Unidimensionality (2020, background): “If this assumption is violated, which one would expect quite frequently in practice, α tends to underestimate the instrument’s reliability (Cheng, Yuan, & Liu, 2012; Dunn, Baguley, & Brunsden, 2014; McDonald, 1999; Revelle & Zinbarg, 2009; Sijtsma, 2009).”
From alpha to omega: a practical solution to the pervasive problem of internal consistency estimation. (2014, background): “…many researchers to be a more sensible index of internal consistency – both in relation to alpha and also when compared to other alternatives (Graham, 2006; Raykov, 1997a,b; Revelle & Zinbarg, 2009; Zinbarg, Revelle, & Yovel, 2007; Zinbarg, Yovel, Revelle, & McDonald, 2006; Zinbarg et al., 2005).”
Fear of Death and Supernatural Beliefs: Developing A New Supernatural Belief Scale to Test the Relationship (2013, methodology): “Overall, the scale composite was reliable, with composite reliability amounting to Ωt = .81 (Revelle & Zinbarg, 2009).”
Determinants of classroom engagement: a prospective test based on self-determination theory (2018, methodology): “Furthermore, McDonald’s omega has shown evidence of better accuracy than Cronbach’s alpha (Revelle & Zinbarg, 2009).”
