Development and Initial Validation of the Computer-Delivered Test Acceptance Questionnaire for Secondary and High School Students

Abstract

This article outlines the development and validation of the Computer-Delivered Test (CDT) Acceptance Questionnaire (CTAQ). The CTAQ was designed to be a practical measure of CDT acceptance of Singapore secondary and high school students (Grades 7-12) toward taking tests within an e-assessment system. The stages of test (questionnaire item) content, response processes, and internal structure under Messick’s unified concept of validity suggested that the CTAQ had sound psychometric properties. Exploratory factor analysis (EFA; n = 485) and confirmatory factor analysis (CFA; n = 484) yielded a three-factor model (ease of use, involvement and experience) with a reduction of 21 to 13 items for CDT acceptance. Practical applications and limitations of the CTAQ are discussed.
