Reliability and Validity of Japanese Versions of the Flourishing Scale and the Scale of Positive and Negative Experience (2013, methodology): “All Cronbach’s alpha coefficients for the FS and SPANE subscales indicate good internal consistency (Henson 2001; Nunnally and Bernstein 1994).”
Development and Validation of Scores on the Distributed Leadership Inventory (2009, methodology): “%) were also evaluated using the method recommended by Fan and Thompson (2001). according to Henson (2001), Loo (2001), and Nunnally and Bernstein (1994), test scores should have reliabilities of .80 or better.”
Measuring students' emotions in the early years: The Achievement Emotions Questionnaire-Elementary School (AEQ-ES) (2012, background): “Cronbach’s alpha internal reliability thresholds are typically set at .70 (Nunnally, 1978) or .80 (Henson, 2001).”
Motivation and Engagement Across the Academic Life Span (2009, methodology): “This is supported by the acceptable reliability coefficients (e.g., see Henson, 2001) also presented in Table 1.”
Measuring the Mathematical Attitudes of Elementary Students: The Effects of a 4-Point or 5-Point Likert-Type Scale (2010, background): “(For more information on effects on internal consistency reliability, see Henson, 2001).”
A Reliability Generalization Study of the Marlowe-Crowne Social Desirability Scale (2002, background): “This was done because score consistency over time and the internal consistency of scores from items on a scale are different facets of reliability (Henson, 2001; Henson&Hwang, 2002).”
Can a self-efficacy-based intervention decrease burnout, increase engagement, and enhance performance? A quasi-experimental study (2011, neutral): “80 (Henson 2001), except dedication (a = .”
Assessing the Multigroup Ethnic Identity Measure for Measurement Equivalence Across Racial and Ethnic Groups (2007, background): “74 for college students, respectively) of internal consistency (Henson, 2001). Worrell (2000) subsequently replicated the distinction between the two components using an adolescent sample and again found scores on both scales to be comparatively consistent (.”
Reliability Generalization of Scores on the Spielberger State-Trait Anxiety Inventory (2002, background): “By referring to the reliability of a test or saying an instrument is reliable, what is generally implied is that once an instrument has been found to be reliable or unreliable, the status it is given is immutable; that reliability does not change (Henson, 2001; Vacha-Haase, Kogan, & Thompson, 2000).”
Measuring Goal Orientation in a Work Domain (2007, methodology): “81 for Competitiveness, indicating that the Work and Competitiveness subscales have adequate internal consistency, but the Mastery subscale has lower internal consistency (Henson, 2001; Lance, Butts, & Michels, 2006).”
A three-wave study of job resources, self-efficacy, and work engagement among Italian schoolteachers (2011, background): “295 Internal consistency for all variables ranged between .84 and .93 (Table 1); thus, all values of Cronbach’s alpha satisfied the value of .80 that is now a generally accepted standard (Henson, 2001).”
Myers-Briggs Type Indicator Score Reliability Across: Studies a Meta-Analytic Reliability Generalization Study (2002, methodology): “For the scales, the TF dimension yielded the only average score reliability below the .80 mark, which is often used as a cutoff for acceptable reliability (Henson, 2001).”
Development of a Theory-Based Assessment of Team Member Effectiveness (2007, background): “As Henson (2001) and Schmitt (1996) noted, the question of what is an acceptable value for a reliability coefficient or whether the use of any cutoff is appropriate is the subject of debate, but .”
Meta-analysis of Cohen’s kappa (2011, background): “Effect sizes in applied research studies are inherently attenuated by unreliable scores (Baugh 2002; Henson 2001; Thompson 1994) and consequently the statistical power of detecting a meaningful difference is lowered.”
A Motivational Perspective on Engagement and Disaffection (2009, background): “80, indicating that some of the correlational results may be attenuated due to measurement error (Henson, 2001).”
Measuring university faculty attitudes toward disability: Willingness to accommodate and adopt Universal Design principles (2011, neutral): “Measures of internal consistency (such as Cronbach’s ) provide the degree to which the items on the instrument combine to measure a single trait; however, Cronbach’s is not as robust as other methods of calculating score reliability such as test-retest or alternate form [16].”
Development and Initial Validation of the Counseling Center Assessment of Psychological Symptoms–34 (2012, background): “Ideally, when the final shortened version is compared with its parent instrument, it should not lose much information, have acceptably high Cronbach’s alphas for its scores (e.g., >.70 for instrument development as suggested by Henson, 2001), and have good content representation of the long version.”
Effects of Self-Efficacy, Emotional Intelligence, and Perceptions of Future Work Environment on Preservice Teacher Commitment (2014, background): “However, because there was one satisfaction item for each expectation the scale could not be separated to confirm reliability of the measures to use in a regression (Henson, 2001).”
