"How are behavioral scientists increasingly involved to advise global decision-makers in the United Nations and elsewhere?"In 2020, the Psychology Coalition at the United Nations (PCUN) launched a bold new series of books, describing how evidence- based behavioral research is increasingly used by United Nations and other decision-makers, to address global issues. These issues reflect the UN's 17 Sustainable Development Goals (SDGs) for 2030-such as health, poverty, education, peace, gender equality, and climate change.This PCUN volume brings together 34 experts in 14 concise chapters, to focus on diverse issues in mental, spiritual, and social health (detailed below). The chapters are co-authored by leading global experts as well as "rising star" students from many nations--offering readers a concise overview of each topic, a glossary of key terms, study questions, and bibliography. This volume is suitable as a textbook for diverse courses in psychology, social work, cross-cultural and international studies.ENDORSEMENTS:"Behavioral Science in the Global Arena" is a milestone in the forging of a global psychologist mental health network, able to offer the United Nations solutions to its quest." - Niels Peter Rygaard, CEO at www.fairstartfoundation.com, and recipient of the 2020 APA International Humanitarian Award"This volume provides students and professionals committed to international work insights on theoretical frameworks, policy implications and best practices using evidence-based approaches." - Barbara W.
