*2.2. Procedure—Data Collection*

The participants were selected by a non-probabilistic convenience sampling based on the voluntary character of the study. The data was obtained using an online survey through Google Forms, and the link was broadcasted through mainstream social media platforms, such as Facebook, Instagram, Twitter, and WhatsApp. This procedure represented the best data collection strategy in the phase of forced social distancing, allowing us to reach the largest number of people. The survey was available from 16 March to 10 May 2020, the time interval between the first working day of forced home confinement and the first working day on which the forced home confinement rules were relaxed. In the first part of the survey, a brief presentation informed the participants about the aims of the study, requesting their anonymous and voluntary participation. Participants could withdraw from the study at any time, without providing any justification, and the data were not saved. To guarantee anonymity, no personal data which could allow the identification of participants were collected. The completed return of the survey implied the electronic informed consent of the person to participate in the study. Only the questionnaire data that had a complete set of answers were considered. The required time to answer the survey was approximately 15–20 min.

The study received a favorable report from the Bioethics Committee of the Burgos University (Reference IR 14/2020) and was conducted in accordance with the ethical principles of the Declaration of Helsinki.
