*3.2. Social Lockdown Perception*

Regarding Social lockdown perception, participants were asked to freely define through a maximum of three words (not sentences) the lockdown period. It was not required to enter words with a specific positive or negative value.

A total of 7209 terms was recorded and then they were grouped through a double-blind procedure into 1045 clusters (terms such as prepositions, articles, and adverbs were removed); in order to minimize the possible experimenter inferences, no changes were made to the different words. Therefore, no adjectives were changed into nouns and vice versa, but only words with the same semantic root and different desinence (e.g., masculine/feminine, singular/plural) were grouped together.

Frequencies analysis results are shown in Figure 1. The 10 most used words were, in descending order: "stressful", with 227 instances (31.5%) followed by "thinking", with 185 instances (25.6%); "sad", with 177 instances (24.5%); "boredom", with 172 instances (23. 8%); "necessary" with 131 instances (18.2%); "missing" with 123 instances (17.6%); "family" with 119 instances (16.5%); "restrictive" with 115 instances (15.9%); "difficult" with 111 instances (15.4%) and "anxiety" with 19 instances (15.1%).
