'The first edition of this book has been a tremendously helpful resource in the humanitarian settings where I have worked over the last fifteen years. The new edition is now firmly aligned with the tools of the mhGAP programme which will make it an invaluable resource for health workers and others who wish to learn what they can do to help people with mental health conditions.' Peter Ventevogel, Senior Mental Health Officer, Public Health Section, United Nations High Commissioner for Refugees, Geneva
