The Less is More: The 17-Item Zimbardo Time Perspective Inventory

In this article the goal was the examination of the factorial structure of a short, Hungarian version of Zimbardo Time Perspective Inventory (ZTPI; Zimbardo and Boyd Journal of Personality and Social Psychology, 77(6), 1271–1288, 1999) in a sample of 1370 participants, comparing alternative factor structures through confirmatory factor analysis (CFA). According to the results the short, 17 item version of ZTPI includes the original five factors and has appropriate model fit indices. Furthermore, it is reliable in terms of internal consistency and temporal stability. In the light of previous ZTPI validations with severe shortcomings, the present results might encourage radical shortening of the original ZTPI scale
