This deliverable presents the results from three activities to provide an in-depth systematic overview of successful strategies to improve Young Carers (YCs’) mental health and wellbeing. The results form a base for a consolidated strategy and theory for the ME-WE intervention and app to be further developed in WP4. A Delphi study gathered insights into the visibility, awareness, interventions and future needs of YCs in six European countries and on an international level. In addition, a systematic literature review, a general literature review, and social media analyses were carried out. Following these tasks, a rating, ranking and consolidation task was performed to iteratively build a dynamic ranked high impact list with national and international strategies and programmes that can serve as exemplars for the ME-WE intervention.
