Construct validation of the Zimbardo Time Perspectives Inventory

The aim of the present study was to validate the factorial structure and psychometric properties of the Zimbardo Time Perspectives Inventory (ZTPI) in a South African student sample. A total of 200 students completed the ZTPI. The sample comprised 58 0.8% female students. Of these, 61.1% were black students and 38.9% were white students. The average age for the sample was 21.59 years. Exploratory and confirmatory factor analyses were used to examine the construct and discriminant validity of the ZTPI. The data suggest ZTPI to comprise four factors of Present-Fatalistic (PF), Present-Hedonistic (PH), Past-Negative (PN), and Past-Positive (PP). Many of the factors cross-loaded onto one or two others, suggesting poor differentiation in the study sample. Scores from the ZTPI were of acceptable reliability. The study results suggest the ZTPI is usable for research purposes in South Africa.
