What are the human consequences of war, conflict and terrorism, and what are the appropriate policy and service responses? This book seeks to provide some answers to these important questions, drawing upon over 25 years’ work by the author in Northern Ireland and elsewhere. Focusing on the work undertaken following the Omagh bombing in 1998, the book describes how needs were assessed and understood, how evidence-based therapy services were put in place and the training and education programmes that were developed to assist first those communities affected by the Omagh bombing - and later the wider population affected by the years of conflict. The author places the mental health needs of conflict-affected victims and communities at the heart of the political and peace processes that follow when conflicts end. This is a practical book and will be of particular interest to those planning for and responding to conflict-related disasters and terrorism, policy makers, service commissioners and providers, politicians, diplomats, civil servants, leaders of religion, peace builders and peace makers. It also includes an extensive overview of the efforts to understand the mental health impact of the years of violence in Northern Ireland, reviewing for example, the impacts of loss and PTSD, why it seemed to take so long to recognise the impact, and the challenges of undertaking research in a community that is in violent conflict.
