Abstract

Introduction. In Spain, to practice as a specialist in any medical specialty, it is necessary to have the corresponding qualification. In order to access training as a specialist, it is mandatory to pass the MIR test. In this article, a psychometric analysis of the 2022 MIR test, held in January 2023, has been carried out using both classical test theory and item response theory. Materials and methods. A subset made up of 3,229 doctors who took the MIR test in 2022 and who entered their response template in a computer application made available for this purpose. Data were analyzed using classical test theory and item response theory. Specifically, Cronbach’s alpha, Kuder and Richardson’s formula number 21, the difficulty index, the difficulty index corrected for chance effects, the discrimination index, the biserial-point correlation index, as well as the difficulty and discrimination indices according to item response theory were calculated. Results. The 2022 MIR test, like those of previous years, shows high reliability. Both the overall results of the test and those detailed by subjects and subject blocks are analyzed. Conclusion. The results obtained in this study allow us to affirm that the MIR exam is an objective exam, of adequate difficulty and discrimination, as well as relatively stable from one call to another.
