This book brings together leading researchers on wellbeing science to provide a multidisciplinary approach to psychological wellbeing with implications for the interconnected societal challenges we face today, including loneliness, neoliberalism, inequality and anthropogenic climate change. Its authors present new and innovative models for understanding, building and improving our understanding of the complex construct of wellbeing. The capacity for individual positive change is explored, as well as the scope for such change to impact on the communities and environments within which we live. Further, the book places individual wellbeing within a broader context that also addresses societal needs and challenges. In doing so, it provides a novel synthesis of individual, societal and environmental perspectives on wellbeing and human flourishing.
