Patients, who agree to participate, will give their written consent. The health care professional will administrate baseline questionnaires, and then will contact the trial center for randomization. Finally, the booklet concerning the intervention, according to allocation group, will be provided to the participant. Anonymity will be guaranteed for both written texts and outcomes assessment.
