DESCAQ development

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.

本 Excel 文件包含 DESCAQ 开发与验证过程中每个数据集的单独工作表。在西班牙语阶段，我们从先前研究中开发的题库中收集数据，并执行 Rasch 分析以校准题目。在英语阶段，我们对大量样本进行了由翻译团队翻译的 DESCAQ 题库的施测，执行了 Rasch 分析以校准题目，并利用所得参数配置了一个新的计算机化自适应测试。该测试在两周内进行了两次施测，以计算测试的重测信度。
