Abstract

This study compares various item option scoring methods with respect to coefficient alpha and a concurrent validity 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. (Author) (18pp.)
