This new edition provides essential reading on crisis intervention for social workers, mental health nurses and other human services practitioners and managers. What defines a crisis can often be misunderstood and incorrectly equated with emergencies. This book explores crisis theory in depth, providing updated and refreshed guidance on what a crisis entails and how to effectively manage traumatic situations. In three distinct parts, the text challenges the dominant individualistic thinking about crises and instead adopts a holistic focus. It expands on crisis theory, examines the implications arising from crises, including links with trauma and the need to address discrimination and oppression. Key points, tips, opportunities for reflection and illustrative case studies are provided to aid understanding and help readers feel confident in tackling crisis intervention to bring about positive outcomes.
