For the psychotherapist/psychological therapist, notions of diversity and inclusion, such as intersectional feminist, trans*, critical race/whiteness, migration, (in)equality, queer, disability, post-colonial, decolonial, approaches and studies, are both increasingly important, and yet increasingly difficult. This book explores these developments and raises the important questions:  Are these difficulties to do with the biases of the person who is the psychotherapist, and/or could it also sometimes have to do with how diversity, inclusion and related terms are constructed? Crucially, clients may now find it difficult to find a therapist who is able to explore with them their concerns around diversity and inclusion which can be complicated and may take time to consider. This book presents cutting-edge research to enable explorations of our changing world which is so different to the one we were born into (let alone our, often older, own psychotherapists and supervisors). Diversity, Inclusion and Culture Wars in Psychotherapy will be a beneficial read for students and scholars of Psychology including Psychotherapy and Counselling. The chapters in this book were originally published as a special issue of European Journal of Psychotherapy and Counselling.
