The aim of this research was to analyze the psychometric properties of the General Intelligence Matrices Test in students from four universities in the city of Lima. To this end, we worked on a nonprobabilistic Peruvian sample of 517 (347 males and 170 females) aged 18 and 31. The method of structural equations (SEM) was used to measure the instrument, which allowed the confirmation of the one-dimensional structure. Similarly, the invariance of the differential analysis of the items was carried out by means of a SEM model and binary logistic regression that indicates the equivalence of measurement. Likewise, it is proposed to work on a reduced structure of the instrument, regarding the measurement of the g factor, as a proposal for the evaluation of intelligence, this with the aim of adapting to the sample in young and adult students evaluated.
