Coefficient Alpha: A Reliability Coefficient for the 21st Century?

Journal of Psychoeducational Assessment, 2011
Coefficient alpha is almost universally applied to assess reliability of scales in psychology. We argue that researchers should consider alternatives to coefficient alpha. Our preference is for structural equation modeling (SEM) estimates of reliability because they are informative and allow for an empirical evaluation of the assumptions underlying ...

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,

Coefficients Alpha for Components

Psychological Reports, 1991
The formula for coefficient alpha for a component is developed. Kaiser's special formula for coefficient alpha for a principal component and the Kaiser-Guttman Rule for the “number of components” are mentioned. A numerical example is added. It is conjectured that the sum of coefficients alpha is invariant under orthogonal rotation.

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 ...

Thermoelastic coefficients of alpha quartz

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1992
Experimental measurements of alpha quartz thermal expansion as reported in the literature have been critically analyzed. A recommended set of best measured values over the temperature range -50 degrees C to +150 degrees C have been determined, as have values for the coefficient of thermal linear expansion (CTE) and the thermoelastic coefficients.
