Testing Zimbardo’s Stanford Time Perspective Inventory (STPI)-Short Form: An Italian study

ABSTRACT. In the present study the psychometric properties of the Stanford Time Perspective Inventory (STPI – short version) are assessed in an Italian sample. Factorial analysis of STPI items was performed on 1507 respondents (965 women and 542 men). Results showed a clear correspondence between factorial components and a priori hypothesized dimensions by evidencing three factors (Future, Hedonistic Present, Fatalistic Present). Italian translation of the STPI indicates a fair degree of internal consistency and good metrological characteristics. The present results parallel those previously reported for an American sample. The present study, however, failed in evidencing the ‘Past’ as a factor in the factor structure. The results are discussed in terms of individual differences with respect to the relationships between demographic variables and temporal dimensions.
