Abstract :

The purpose of this study was to examine the psychometric properties of Zimbardo’s Time Perspective Inventory(ZTPI) among adolescents. A sample of 866 high school student adolescents aged 14-18 years after selecting by cluster sampling, participated in the study. However Confirmatory Factor Analysis acquired unacceptable fit indexes for the posited five-factor structure, using Exploratory Factor Analysis supported the original factor structure of the ZTPI, 42 of the 56 items belong to their appropriate factors and 8 items had cross-loadings over .30 on inappropriate factors. A total of 4 items did not show a substantial loading (>.3) on any of the factors and at least 20 items emerged with factor loadings less than .40. Similar to the results of previous research, current study recommended the use of the instrument only with serious caution in the adolescents’ population.
