Time in adolescence. Validating Zimbardo’s Stanford Time Perspective Inventory using a sample of Italian adolescents

In this study, we explore the psychometric characteristics of Zimbardo’s Stanford Time Perspective Inventory, using a representative sample made up of 1517 Italian adolescents, aged 15-19 years. The results show marked differences with respect to preceding studies conducted in the United States and Italy. In particular, the scale of the present forms a single dimension, losing its subdivision into two distinct dimensions, hedonistic and fatalistic. The two scales found in factor analysis, present and future, show a good degree of internal consistency and discriminating validity. Results are interpreted according to the individual differences present in the sample and to the cultural and economic changes occurring at this specific moment of history.
