A Meta-Analysis of Cronbach's Coefficient Alpha

Journal of Consumer Research, 1994
Despite some limitations, Cronbach's coefficient alpha remains the most widely used measure of scale reliability. The purpose of this article was to empirically document the magnitudes of alpha coefficients obtained in behavioral research, compare these obtained values with guidelines and recommendations set forth by individuals such as Nunnally (1967,

Cronbach’s alpha (α) is a widely-used measure of reliability used to quantify the amount of random measurement error that exists in a sum score or average generated by a multi-item measurement scale.

Cronbach's alpha reliability coefficient

Journal of Mood Disorders, 2016
In statistics, Cronbach’s alpha coefficient is used as an estimate of the reliability of a psychometric test. It might have calculated either for each item in the scale or an average value for all items in the scale. The reliability of the scale is accepted as good if the coefficient is found equal or greater than 0.70.

Rethinking Internal Consistency in Cronbach's Alpha

Leisure Sciences, 2016
ABSTRACTCronbach's alpha estimates the internal consistency of responses in multi-item bipolar scales. This article examined three research questions (RQ): (1) To what extent do inconsistencies exist in data (e.g., responses of −2 −2 2 2)? (2) Does the number of scale items influence the amount of inconsistency?

Cronbach’s Coefficient Alpha

Organizational Research Methods, 2014
This study disproves the following six common misconceptions about coefficient alpha: (a) Alpha was first developed by Cronbach. (b) Alpha equals reliability. (c) A high value of alpha is an indication of internal consistency. (d) Reliability will always be improved by deleting items using “alpha if item deleted.” (e) Alpha should be greater than or ...
