| Abstract: | An empirical investigation of the effect of choice weight scoring on predictive validity and reliability. Choice weight scoring refers to the procedure whereby different weights may be assigned to all the options of an item. Four groups of subjects were included in the experiment. Weights derived from each group were used to score tests for another group in order to assess the cross-validity of the weighted scoring. In no case did the increments in reliability and validity due to the weighted scoring exceed .03. |
