This book explores children's mental health and wellbeing issues using a developmental systems perspective that is grounded on established theoretical frameworks and supported by evidence-based research. It uses Singapore as a unique example to illustrate the range of nationwide educational, clinical and social initiatives and programs, anchored on systems thinking and viewed through a systems perspective. The book covers topics including barriers to help-seeking, addressing children's mental health needs, and how to enhance mental health support for children and adolescents. It draws on examples from Singapore's education, health, family, social services and legal sectors in promoting children's mental health and wellbeing. Future directions in the field will be discussed including the importance of program evaluation, partnerships, and bringing interventions to scale. In order to fully realize the ultimate aim of sustaining a long-term positive and healthy mental state for our young, the book highlights how a well-coordinated national strategy for mental health and wellbeing can serve as a springboard for further growth to build a resilient and empathic society. An essential resource for academics, researchers and postgraduate students in the fields of school, clinical and counselling psychology, counselling, social work, education and related disciplines, this book will also interest clinicians or practitioners.
