Metrics for Explainable AI: Challenges and Prospects (2018, background): “…0.86; ES items had item-total correlations ranging from 0.41 to 0.76 and an average inter-item correlation of 0.71, indicative of excellent internal consistency reliability, especially for such a brief scale that is very easy to administer and score (Comrey, 1988; Cortina, 1993; Streiner, 2003).”
Internal Consistency, Retest Reliability, and their Implications For Personality Scale Validity (2010, background): “The preceding discussion has been predicated on the assumption that it makes sense to consider reliability and validity coefficients as characteristics of trait measures themselves, whereas psychometricians are careful to point out that these are properties of measures used in particular samples or ”
Being Inconsistent About Consistency: When Coefficient Alpha Does and Doesn't Matter (2003, background): “Inapreviousarticle (Streiner,2003), Idiscussed thatoneof the major tenets of classical test theory is that all of the items in a scale tap a single domain or attribute such as anxiety or achievement motivation.”
Development and validation of the Current Opioid Misuse Measure (2007, methodology): “While there is some disagreement on what constitutes acceptable levels of internal consistency parameters (e.g., Nunnally and Bernstein, 1994; Streiner, 2003a,b; Butler, 2004), we adopted the convention of acceptable coefficient as as being between .70 and .80, as suggested by others developing…”
Guidelines for developing, translating, and validating a questionnaire in perioperative and pain medicine (2017, background): “It is important to note that Cronbach’s alpha is a property of the responses from a specific sample of respondents.[31] Investigators need to keep in mind that Cronbach’s alpha is not “the” estimate of reliability for a questionnaire under all circumstances.”
Individual differences in attitudes towards gossip (2005, background): “Streiner (2003) noted that reliability is, to a certain extent, a characteristic of the sample as much as it is of the scale.”
Burnout, Stress, and Direct Student Services Among School Counselors (2016, methodology): “The internal consistency coefficients of the CBI in this investigation also were good (Streiner, 2003) with Cronbach’s alphas of .”
The Measurement of Curiosity As a Feeling of Deprivation (2004, background): “…considered to indicate acceptable, if not desirable, internalconsistencygiven thateachsubscaleconsistedof only five items and that this study reflected only the very early stages of research on CFD as a psychological construct (Cortina, 1993; DeVellis, 1991; Nunnally, 1967, 1978; Streiner, 2003).”
Use Omega Rather than Cronbach’s Alpha for Estimating Reliability. But… (2020, methodology): “Cortina (1993) and Schmitt (1996) addressed several of these misunderstandings decades ago, but they persist (for more recent discussions, see Sijtsma, 2009; Streiner, 2003).”
Coefficient Alpha: Interpret With Caution (2013, neutral): “Many authors have pointed out that alpha is inappropriately used in studies mainly because satisfactory, or even high, values of alpha are persistently and incorrectly used as an indication of the unidimensionality of the scale (Cortina, 1993; Nunnally & Bernstein, 1994; Schmitt, 1996; Sijtsma, 2009”
Findings from a Pre-kindergarten Classroom: Making the Case for STEM in Early Childhood Education (2017, background): “These values can be considered adequate for low-risk applications (Streiner, 2003).”
