Summary/Abstract: The present study assesses the psychometric properties of the Zimbardo Time PerspectiveInventory (ZTPI) in a German sample of N = 160 individuals. The five subscales (PastNegative, Present-Hedonistic, Future, Past-Positive, and Present-Fatalistic) measure differentdimensions of the Time Perspective. The German version of the ZTPI proves to be internallyconsistent and reliable in retests, except for the Future Scale. Retest reliability for a subsample (N = 25) indicates a stable measurement of the scales. The Zimbardo and Boyd’s(1999) factor structure could not be replicated satisfactory. Correlations with conceptuallyrelated tests (IPC, HAKEMP, and HEIPI) indicate a fair degree of construct validity within theframework of classical test theory. The fit according to a Rasch model was not successful.
