Book excerpt: Healthcare delivery systems have evolved to rely more heavily on technology in recent years. There has been a shift in care, diagnosis and treatment which has decreased the importance of traditional methods of care delivery. Technology has not only helped to extend our lifespan, but it has improved the quality of life for all citizens. This book presents the proceedings of the 20th Annual CyberPsychology, CyberTherapy & Social Networking Conference (CYPSY20), held in San Diego, California, in June/July 2015. The conference is an international networking and sharing platform for researchers, clinicians, policymakers and funding agents to share and discuss advancements in the growing disciplines of CyberTherapy & CyberPsychology. The papers included here have been divided into six main sections: editorial; critical reviews; evaluation studies; original research; clinical observations and work in progress. The book underlines how cybertherapy has started to make progress in treating a variety of disorders, and provides an overview of the necessary skills and tools available, as well as illuminating the context of interaction in which they operate.
