Participants were recruited via an advertisement sent by email, in which the aims and objectives of the research were explained. Contact details of the participants were provided by school administrators who authorized the data collection.

A sample of 148 Italian students, aged between 17 and 19 (average age 17.9 ± 1.2), 84 females and 64 males, attending the last two years of high school, participated in the study.

Informed consent was obtained from adolescents over the age of 18; parental consent was required for minors to participate in the study. The study respected the anonymity and privacy of each participant, and was conducted in accordance with the Declaration of Helsinki. Moreover, 23 subjects were excluded because their questionnaires were not completed or showed some apparent inconsistencies.
