Participants will follow a positive emotional induction training for 3 weeks, with 2 exercises per week.

The first week, they will listen to a piece of music and watch a video that elicits positive emotions; the second week, they will do an activity that they particularly enjoy in solitude and listen to a narrative about gratitude; the third week, they will listen to a narrative about hope and carry out an activity they like with a loved one. The participants will complete some questionnaires at baseline, post-intervention, and in the one-month follow-up.

Developed by Radloff (1977), it is a 20-item self-report scale used as a screening tool for depression in the elderly. For the purpose of this study, the 10-item short version, validated by Andersen and colleagues in 1994, will be used. Participants will be asked to indicate on a 5-step Likert scale, where 0 corresponds to "never or almost never" (less than 1 day), 1 corresponds to "sometimes or infrequently" (1-2 days), 2 corresponds to "occasionally or for a moderate amount of time" (3-4 days), and 4 corresponds to "most of the time or all of the time" (5-7 days), how they have been feeling in recent weeks. For the purpose of this study, the items have been translated into Italian.

- Item ad hoc to investigate perceived usefulness and pleasantness of the exercise just done. After each activity of the training, participants will be asked to rate perceived usefulness and pleasantness through a 7-step Likert scale where 1 corresponds to "very little" and 7 to "very much."

A 5-item questionnaire, scored on a 7-step Likert scale, where 1 corresponds to "not at all" and 7 to "very much," will be proposed, aimed at investigating the subject's experience of using the website. In particular, the degree of aesthetic pleasantness of the website, its functionality, and the ability to engage the user will be investigated.

The perceived usefulness of the training will be measured through a single item ("Referring to the entire training, how useful do you think it was for you?") that can be answered through a 7-step Likert scale where 1 corresponds to "very little" and 7 to "very much." In addition, there will be a section where it will be possible to express a reflection regarding the evaluation provided.

Two items ad hoc will be administered to investigate which exercise they found most useful and which was the most enjoyable, specifying their reasons. In addition, they will be optionally asked to express a general reflection on the exercise they did. These ad hoc items will be differentiated according to their group. In fact, for the experimental group, reference will be made to the exercises proposed in the e-savoring training, while for the control group, positive emotion induction activities will be reported. The aim of these final items is to understand which exercises were found most useful and enjoyable overall by the participants, both in the control and experimental groups, so as to take them into account for future studies.

Participants will be asked about the frequency with which they have put into practice in the last month the exercises experienced during the training for both the experimental and control groups.
