Adolescence is among the most significant periods in humans҆ life. Future time perspective (FTP) plays a significant role in performance during this period, and it can also influence life-span development. Therefore, it is necessary to have appropriate scales in different languages and cultures to assess it. In this regard, the future time perspective scale for adolescents and young adults (FTPS-AYA) was devised to evaluate the FTP among adolescents and young adults. Accordingly, the present study was conducted to determine validity, reliability, and factor structure of the Persian version of the FTPS-AYA in the Iranian subjects. For this purpose, a total of 600 high school female students participated in the study and responded to the Zimbardo time perspective inventory (ZTPI) and the Persian version of FTPS-AYA. The test-retest coefficient and Cronbach’s alpha were acceptable for the total score of the Persian version of FTPS-AYA and its subscales. A significant correlation between subscales and the total scores and between items and the total score indicated high internal consistency of FTPS-AYA. A significant relationship between the factors of FTPS-AYA and the future factor scores of the ZTPI showed concurrent validity. Confirmatory factor analysis was performed to investigate validity of the six-factor structure. It was concluded that the modified model can improve the indices. Overall, the results indicated that the six-factor structure was optimally fitted in the study’s sample population and was sufficiently valid therefore; the proposed six-factor structure was supported.
