Development of Short and Very Short Forms of the Children's Behavior Questionnaire (2006, methodology): “Internal consistency. Alpha coefficients obtained for the scales of the standard and short forms are shown in Table 1. Standard errors for these alphas, which we calculated using a method described by Iacobucci and Duhachek (2003) , were all less than .01.”
From alpha to omega: a practical solution to the pervasive problem of internal consistency estimation. (2014, background): “Iacobucci and Duhachek (2003) point out that for a simple 2-item scale with an item inter-correlation of .60 and a sample of 30, coefficient alpha is .75 with 95% CIs from .64 to .86.”
Enjoying loyalty: The relationship between service quality, customer satisfaction, and behavioral intentions in public transit (2016, methodology): “In addition, all constructs showed values of Cronbach’s Alpha greater than the cut off value of 0.7 (Iacobucci & Duhachek, 2003).”
Handling Item-Level Missing Data (2013, positive): “The 95% confidence intervals are also reported for all alphas (using syntax from Iacobucci & Duhachek, 2003).”
The mediating role of competitive strategy in international entrepreneurial orientation (2016, background): “To determine the magnitude of this indirect effect, Iacobucci and Duhachek (2003) propose the VAF (Variance Accounted For), which indicates the size of the indirect effect in relation to the total effect (direct effect + indirect effect): VAF = (a1b1) / (a1b1 + c′), obtaining a value of 0.62…”
The quality and effectiveness of descriptive rubrics (2015, background): “For example, Iacobucci and Duhachek (2003) suggested alpha values of 0.70 can be acceptable for the early stages of research.”
Cronbach's Alpha: Review of Limitations and Associated Recommendations (2010, background): “However, these guidelines are not empirically grounded (Helms et al., 2006; Iacobucci & Duhachek, 2003; Schmitt, 1996).”
Organisational resilience capacity and firm product innovativeness and performance (2014, methodology): “cronbach’s alpha), the usage of two items do not negate the value of the variables where such item measures are appropriate (Iacobucci and Duhachek 2003). Indeed, most of the studies utilise the two-item scales when the two items can tap the variable of interest. Also, as recommended, we assessed th”
Treating Cronbach’s Alpha Reliability Coefficients as Data in Counseling Research (2006, methodology): “Adapting Iacobucci and Duhachek’s (2003) recommendation for reporting CIs, we could report our current CI for the obtained alpha coefficient for the DG Reintegration scale score as follows: “Our obtained Reintegration scale score reliability was .”
Tightwads and Spendthrifts (2008, positive): “Table 4 presents these scales, their standardized alphas (Iacobucci and Duhachek 2003, 486), and their zero-order correlations with the ST-TW scale.”
Student Evaluation of University Image Attractiveness and Its Impact on Student Attachment to International Branch Campuses (2013, background): “In the case of factors with only two items (like our Distinctiveness factor), α values above .60 are generally acceptable (Iacobucci & Duhachek, 2003).”
Leadership style and regulatory mode: Value from fit? (2006, background): “Given that these reliabilities fall below acceptable levels ( Iacobucci & Duhachek, 2003 ), future research should attempt to develop more robust measures of transactional leadership or clarify the conceptualization of this construct.”
The α and the ω of Congeneric Test Theory: An Extension of Reliability and Internal Consistency to Heterogeneous Tests (2005, methodology): “Programs for calculating α̂ and its standard error are available (Iacobucci & Duhachek, 2003; Konig & Franses, 2003).”
