With specially commissioned introductions from international experts, this title draws together previously published chapters on key themes in psychological science that engage with people's unprecedented experience of the pandemic. In this volume on health, the authors introduce chapters that explore the crucial topics of health behavior change, wellbeing, stress, and coping. They highlight the key role digital health technologies can play in how we manage health conditions, and how we facilitate change to help individuals manage stressful situations such as physical isolation, job loss, and financial strain during the COVID-19 pandemic. The volume also offers an important overview of environmental and policy-based approaches to health behavior change and addresses the highly relevant issues of identity and trust and how they shape the health of individuals, communities, and society. Highlighting theory and research on these key topics germane to the global pandemic, the Psychological Insights for Understanding COVID-19 series offers thought-provoking reading for professionals, students, academics, and policymakers concerned with psychological consequences of COVID-19 for individuals, families, and society.
