Description

This excel file contains a sheet for each of the data in the development and validation of the DESCAQ. In the Spanish phase, we collected data from an item bank developed in previous studies and performed Rasch analysis to calibrate items. In the English phase, we administered to a big sample the DESCAQ item-bank as translated by the translation team, we performed Rasch analysis to calibrate items and used the resultant parameters to configurate a new computerized adaptive test. This test was administered twice within two weeks for calculating the test-retest repeatability.
