Coefficient Alpha and Composite Reliability with Interrelated Nonhomogeneous Items.
Raykov, Tenko
Applied Psychological Measurement, v22 n4 p375-85 Dec 1998
Examines the relationship between Cronbach's coefficient alpha and the reliability of a composite of a prespecified set of interrelated nonhomogeneous components through simulation. Shows that alpha can over- or underestimate scale reliability at the population level. Illustrates the bias in terms of structural parameters. (SLD)
