Exploring the possibility to use Set I of Advanced Progressive Matrices as a short form of Standard Progressive Matrices
The present paper aimed to explore the possibility of using the Advanced Progressive Matrices ‒ Set I (APM-Set I) as a short form of Standard Progressive Matrices for sound assessment of general mental ability in a short time frame. Confirmatory factor analysis for dichotomous data attested the unidimensionality of APM-Set I, and then the Rasch model was applied. All items showed an acceptable fit, and the increasing order of items difficulty level was partially confirmed. Validity measures were also performed. Results supported the possibility of using APM-Set I as a short form of the Raven Matrices test.Back
