Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

Objective:

This study aimed to test, using the Confirmatory Factor Analysis model, the factor structure proposed in the Intellectual Styles Inventory – Revised 2.

Methods:

The study involved the participation of 1,556 High School students with a mean age of 16 years and 4 months (SD = 1.17).

Results:

Confirmatory Factor Analysis was used and the model was based on the structure of 46 items distributed in nine dimensions, having demonstrated good rates of fit and accuracy. It was verified that the model originally indicated by the scientific literature was not confirmed in the Brazilian context, being proposed modifications that bring the current model closer to the national reality.

Conclusion:

There was an adjustment in the estimates of the parameters used, and stability and generality can be considered in the way the model was organized.
