The present study analyzes the psychometric properties of the Scale for Existential Thinking (SET) in a sample of Portuguese university students with the Rasch model. The results indicate that the items are well fitted to a latent unidimensional structure, as required by Rasch modeling. The response scale showed proper functioning; therefore, people and item parameters were estimated with high precision. DIF analyses confirmed no differences in the results concerning gender. Correlational analyses with additional measures support construct and criterion-related validity. Limitations of this study and the psychometric implications of its results are discussed, providing suggestions for future research.Downloads
