The Effects of Heterogeneous Item Distributions on Reliability.
Enders, Craig K.; Bandalos, Deborah L.
Applied Measurement in Education, v12 n2 p133-50 1999
Examined the degree to which coefficient alpha is affected by including items with different distribution shapes within a unidimensional scale. Computer simulation results indicate that reliability does not increase dramatically as a result of using differentially shaped items within a scale. Discusses implications for test construction.
