In its broadest sense, community psychology studies the individual's relationships to their community and to wider society. Sitting at the junction between social and clinical psychology, and heavily influenced by activist traditions in political science, sociology and social work, this powerfully written book delivers a comprehensive introduction to the definition and aims of this justice-orientated field of psychology. Editors Nelson and Prilleltensky cover a broad range of the critical perspectives and fundamental values that define the aims of community psychology, highlighting the psychosocial praxis that these have produced and the key political and societal ills that they aim to prevent. Written with a global perspective, this book exhibits internationally authored chapters as well as in-text commentators and cross-cultural case studies. This book is a key guide to understanding how community psychologists function to resolve structural injustice and bring about transformative change to the socio-economic issues of our time such as homelessness, mental health, racism, discrimination and marginalisation. This text can be used as an essential guide for undergraduate students beginning courses in Community Psychology as it presents a thorough history of the field, a rigorous breakdown of the various socio-economic issues at the heart of community psychology's focus, as well as a critical analysis of methods of intervention and research.
