The project aims to evaluate the effectiveness, through a multicenter study, of a new group intervention model called Me.Mo, designed to promote mentalization abilities and social skills in young adults. The Me.Mo intervention was developed by our research group in collaboration with the University of Perugia and the University of L'Aquila in a sample of young adults. The project is conceived as a randomized multicenter study. The student sample will be selected based on the administration of an online survey. Subjects who meet the inclusion/exclusion criteria will be assigned to two experimental conditions: in-person Me.Mo iand Me.Mo intervention via a web-based app. The research fellow's work will consist of collecting data related to the interventions, overseeing the process of assigning subjects to experimental groups, managing the database, and analyzing the data.
