Abstract
This study compares various item option scoring methods with respect to coefficient alpha and a concurrent validity coefficient. The scoring methods under consideration were: (1) formula scoring, (2) a priori scoring, (3) empirical scoring with an internal criterion, and (4) two modifications of formula scoring. The study indicates a clear superiority of the empirically determined scoring system with respect to both coefficient alpha and the concurrent validity.
