Containing a novel compilation of theoretical and methodological approaches, this textbook lays out the most relevant foundations of clinical sociology. Relying heavily on well-recognized medical models and concepts to help communicate ideas (e.g. treatment, diagnosis, clinical, cure), the methods of social diagnosis and social therapy presented in this book will help in better and socially informed protection of vulnerable individuals and citizens as well as an informed design of protection policies for macro, meso and micro levels of society. The book explains that many problems, perceived as economic, psychological-individual, and political, are rooted in social functions and structures of the wider society, and how these social structures and functions interact in everyday life. Through the application of the theoretical and methodological approaches in case studies on recent issues, such as the Covid pandemic, or the Hurricane Katrina disaster, the book will allow readers to easily cope with the complexity of clinical sociology and to develop clinical competencies and pertinent training. This renders the book not only highly useful for advanced undergraduate and graduate students of clinical and applied sociology but also for the preparation of courses for theoretically informed practitioners who are keen to work by defining learning objectives and learning paths.
