Analysis of psychometric properties of the cube test to evaluate visuospatial reasoning

Abstract

The objective of the present research was to contribute with new information regarding the validity evidence of the Cube Test. More specifically, psychometric properties of the items were analyzed through the Item Response Theory (IRT) and the test structure was analyzed using Confirmatory Factor Analysis (CFA). The sample was composed of 684 subjects, with a mean age of 21.3 years (SD = 5.94) and 50.3% were female. Results showed that IRT analyses confirm the adjustment of the items to the model, whereas the CFA suggested that a two-factor model was the most adequate. The findings, besides offering favorable results about the instrument, supported the validity evidence present in the Cube Test manual.
