2.3.6. Stanford Time Perspective Inventory (STPI—Short Form)

This instrument provides a simple way to measure multiple temporal perspectives of individuals, and is built on a theoretical basis that examines the emotional, social, cognitive and motivational processes that are supposed to contribute to, and are in turn influenced by, the functioning of the temporal perspective [29]. Based on the specific purpose of this study, a selection of the original 22-item scale was made, whereby only 9 items were used, and all the answers were on five-point response scales ranging from "Never" (0) to "Very often" (4).

## 2.3.7. Future Forecasts

Finally, the authors developed a scale in relation to the future forecasts expressed by respondents. Thirteen items were elaborated (for example, "Overall health management will improve"), with a 5-point Likert scale response from "Completely unlikely" (0) to "Very likely" (4).

## 2.3.8. Social Lockdown Perception

A single item was formulated to investigate thoughts and moods related to the lockdown; participants were asked to answer the question "Try to define in a few words this period of relational and social life restrictions".
