    The present study analyzes the psychometric properties of the Future Time Perspective Scale(FTPS)in a sample of Portuguese university students with the Rasch model. The results indicate that subscale items are well fitted to latent unidimensional structures, as required by Rasch modeling. The response scale showed proper functioning with the exception of speed subscale; therefore, people and item parameters were estimated with high precision.DIF analysesconfirmed no differences between genders in the results. Limitations of this study and the psychometric implications of its results are discussed, providing suggestionsfor future research.

    O presente estudo analisa as propriedades psicométricas da Future Time Perspective Scale (FTPS) numa amostra de universitários portugueses, usando o modelo de Rasch.  Os resultados indicam que os itens das subescalas ajustam a estruturas latentes unidimensionais, pressuposto requerido pelo modelo de Rasch.  A escala de resposta apresentou funcionamento adequado, excepção feita à subescala de rapidez, permitindo que os parâmetros de pessoas e itens fossem estimados com elevada precisão.  Análises DIF confirmaram a inexistência de diferenças nos resultados relativas ao género. São discutidas as limitações do estudo e as implicações psicométricas dos resultados para futuras investigações.
