| Sumario: | There is a need for brief instruments on personality in the Peruvian context. Therefore, the objective of the study is to analyze the validity of the Mini - International Personality Item Pool (Mini-IPIP) and its factorial invariance. The method used was instrumental. The participants were 521 university students from a university in Lima. The instrument used was the Mini-IPIP, consisting of 20 items with five response options. Confirmatory factor analysis and factorial invariance was used through R studio software. The results showed that the final model (MF) obtained better fit rates than the other tested models (MP, M1 and M2). The extraction of items in the MF increased the reliability of the factors. Factorial invariance determined that there is no difference between gender. In conclusion, the MF is better suited to the reality of the Peruvian sample by obtaining higher values from goodness-of-fit indices. |
