S. Valentine et L. Silver, Assessing the dimensionality of the Singhapakdi, Vitell, and Kraft measureof moral intensity, PSYCHOL REP, 88(1), 2001, pp. 291-294
In a sample of 105 students, the dimensionality of a moral intensity scale
developed by Singhapakdi, Vitell, and Kraft in 1936 was assessed. Principal
components analysis yielded a one-factor solution across 10 ethics scenari
os, indicating that moral intensity may be treated as a unidimensional cons
truct in some situations.
