The World Health Organization (WHO) emphasizes that “there can be no health or sustainable development without mental health .” Achieving the United Nations Sustainable Development Goal (SDG) 3, which aims to “promote well-being for all at all ages,” requires addressing mental health challenges, particularly among older adults. To address this need, an online Master’s programme in e-mental health and wellbeing is proposed, focusing on equipping professionals with the competencies to leverage digital and cognitive technologies in enhancing mental health for older adults. This programme prioritizes understanding the foundations of mental health, assessing and intervening effectively, and providing support through innovative technologies and community-building strategies. Key drivers for developing this initiative include the growing global emphasis on mental health as integral to sustainable development, the rising demand for specialized interdisciplinary knowledge in mental health for aging populations, and the potential of digital tools to bridge existing gaps in care (public, private). The interdisciplinary curriculum is designed to support inclusive and diverse entrants from fields such as clinical practice, psychology, mental health nursing, disruptive technology, and industry, integrating core and advanced skills in digital mental health. Emphasis is placed on trust, transparency, safety, and ethics in mental health technology applications, ensuring professionals are well-equipped to address authentic and real-world challenges. The programme also focuses on interdisciplinary collaboration, reflecting the complexity of addressing mental health needs in older adults. In a joint cooperation through an Erasmus+ project between universities from Austria, Finland, Germany and Ireland, we are developing a master's programme that addresses these SDGs challenges to support workplace resilience, and sustainability for an unscripted future.
