The research project titled “Mental Health in the Workplace: Multilevel Interventions to Promote Mental Health in SMEs and Public Workplaces” spans over three years and is coordinated by the Alma Mater Studiorum of the University of Bologna, Italy. The project brings together 14 partners from nine European countries. The researchers will develop and evaluate measures, tools and models that can be used at different levels of small and medium-sized businesses and public organisations to create workplaces that promote positive mental health, protect against mental disorders and support employees who experience mental health problems.
