VLAT: Development of a Visualization Literacy Assessment Test (2017, methodology): “Thus, an alternative method, reliability coefficient omega [35], is often used in a practical situation [21] [35].”

Making Reliability Reliable (2016, methodology): “In addition to Jöreskog’s (1971) work, two approaches deserve mention. Let pi denote the ratio of the length of item i (i.e., li) to the total length (i.e., Pk i1⁄41 li), and let siX denote Pk j1⁄41 sij. Raju’s (1977) generalization of his previous formula (~ rR1977) is algebraically equivalent to r”
A Review of Key Likert Scale Development Advances: 1995–2019 (2021, methodology): “McNeish (2018) provides a software tutorial in R and Excel [see also Dunn et al. (2014) and Revelle and Condon (2019)].”
Use Omega Rather than Cronbach’s Alpha for Estimating Reliability. But… (2020, methodology): “Cronbach’s 1951 Psychometrika paper has been cited more than some of the most influential research in the sciences (Dunn et al., 2014; Sijtsma, 2009), and Cronbach’s α is the dominant measure of reliability reported in studies that rely on a MIMS.”
A Psychometric Network Perspective on the Validity and Validation of Personality Trait Questionnaires (2019, background): “Despite α’s prevalence, there are some serious issues (Dunn, Baguley, and Brunsden, 2014; Sijtsma, 2009).”
