Applications of ACER ConQuest software, use of software, multidimensional item response analysisAbstract
ACER ConQuest is a generalized Rasch-type item response modelling software. It is widely used in the fields of measurement, psychometrics, and educational assessment. This paper introduces ConQuest’s functions, the analysis models fitted, and its applications. An analysis example is shown for investigating psychometric properties of a psychological instrument with a multidimensional item response theory (MIRT) model. The paper displays preparation of the input files and the main analysis outputs. Finally, a number of useful studies and resources have been provided for users to conduct more comprehensive analyses with ConQuest.
