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).”
The 20-Item Toronto Alexithymia Scale. III. Reliability and factorial validity in a community population. (2003, background): “Although the results of the present study strongly support the continuing use of the TAS-20 for clinical and research purposes, factorial validity is not sufficient to establish beyond question that the items of a scale are actually measuring what they are intended to measure [37,51].”
Modified Auxiliary Equation Method versus Three Nonlinear Fractional Biological Models in Present Explicit Wave Solutions (2018, unknown): “We balanced the terms in Equations (8)–(10) to get the balance value of each of them, obtaining the value of balance equal to one in all of them.”
The structure of virtue: An empirical investigation of the dimensionality of the virtues in action inventory of strengths (2010, methodology): “One of the best ways to evaluate data dimensionality is replication of a specified structure in a new sample using exploratory factor analysis (Comrey, 1988; Gorsuch, 2003).”
Measuring Perceived Teacher Support and Its Influence on Adolescent Career Development (2008, result): “The presence of a single, higher order factor for the measure provides support for the notion that all four factors underlie a common construct and confirm the multidimensionality of the TSS (Comrey, 1988; Reise et al., 2000).”
Constructing Validity: New Developments in Creating Objective Measuring Instruments (2019, methodology): “Consistent with general guidelines in the broader factor analytic literature (e.g., Comrey, 1988; Fabrigar, Wegener, MacCallum, & Strahan, 1999; Russell, 2002), we recommend using principal factor analysis (PFA vs. principal components analysis; PCA) as the initial extraction method (but see…”
Normas para el desarrollo y revisión de estudios instrumentales (2015, background): “…y teniendo en cuenta la mayor facilidad de aplicación e interpretación, se recomienda el uso del análisis de componentes principales (ACP) (Cortina, 1993) y la rotación ortogonal Varimax (véase Comrey, 1988 o Floyd y Widaman, 1995 para una Int J Clin Health Psychol, Vol. 5, Nº 3 mayor información).”
The measurement of populist attitudes: Testing cross-national scales using item response theory (2020, background): “That is, formative models like PCA conceptualise constructs as causally determined by the items, rather than the other way around (Comrey, 1988; Edwards and Bagozzi, 2000).”
The Measurement of Curiosity As a Feeling of Deprivation (2004, methodology): “20 or higher were considered for retention, whereas the remaining items were deleted (Comrey, 1988; Jarvis & Petty, 1996).”
Development and Validation of a Stages of Change Measure for Men in Batterer Treatment (2000, methodology): “The sequential system for scale development described by Jackson (1970, 1971) and Comrey (1988) was used.”

Achievement goal orientations and the use of coping strategies among Winter Olympians (2003, methodology): “Comrey (1988) recommends an alternative procedure where a measure of internal consistency, measured by coefficient alpha (Cronbach, 1951), for each subscale, is used to check whether the items are measuring the same constructs.”
