Decolonizing Global Mental Health is a book that maps a strange irony. The World Health Organization (WHO) and the Movement for Global Mental Health are calling to ‘scale up’ access to psychological and psychiatric treatments globally, particularly within the global South. Simultaneously, in the global North, psychiatry and its often chemical treatments are coming under increased criticism (from both those who take the medication and those in the position to prescribe it). The book argues that it is imperative to explore what counts as evidence within Global Mental Health, and seeks to de-familiarize current ‘Western’ conceptions of psychology and psychiatry using postcolonial theory. It leads us to wonder whether we should call for equality in global access to psychiatry, whether everyone should have the right to a psychotropic citizenship and whether mental health can, or should, be global. As such, it is ideal reading for undergraduate and postgraduate students, as well as researchers in the fields of critical psychology and psychiatry, social and health psychology, cultural studies, public health and social work.
