The Zimbardo Time Perspective Inventory (ZTPI; Zimbardo & Boyd, 1999) assesses five time-related constructs - Past Negative (PN), Past Positive (PP), Present Fatalistic (PF), Present Hedonistic (PF), and Future (F) - and is one of the most frequently used time measures in the extant literature. Versions of the ZTPI have been translated into a variety of languages, but the psychometric support for ZTPI scores remains contested. We examined the internal consistency, structural validity, and convergent validity of scores on a version of the ZTPI that consisted only of items that specifically referenced time constructs, the ZTPI-TP. Participants consisted of five samples of adolescents and adults from four countries: Australia (653 adults), Slovenia (425 adolescents and adults), the United Kingdom (913 adolescents; 455 adults), and the United States (815 adolescents). Structural validity analyses provided stronger support for ZTPI-TP scores than for ZTPI scores, and convergent validity evidence also provided support for ZTPI-TP scores. However, analyses revealed that the PF and PH factors were still problematic, especially with regard to factor coefficients and internal consistency estimates. We concluded that the ZTPI-TP can form the basis for a more robust version of the ZTPI.
