The Reliability and Validity of Zimbardo Time Perspective Inventory Scores in Academically Talented Adolescents

Abstract

In this study, the authors examined the reliability, structural validity, and concurrent validity of Zimbardo Time Perspective Inventory (ZTPI) scores in a group of 815 academically talented adolescents. Reliability estimates of the purported factors' scores were in the low to moderate range. Exploratory factor analysis supported a five-factor structure similar to the one proposed by Zimbardo and Boyd but also provided support for a six-factor structure that included an additional factor reflecting negative feelings about the future. ZTPI subscale intercorrelations were generally low, and intercorrelations between ZTPI subscale scores and other constructs were low, but in the expected directions. Results are discussed in light of the ZTPI's application to an adolescent-aged population.
