"How the Mind Charity is Putting 'Mental Health Professionalism' back 70 Years" is a thought-provoking book that sheds light on the practices of the Mind charity and its impact on mental health professionalism. The book argues that the charity's therapists readily refer people to mental health services because they lack sufficient training to provide effective therapy themselves, unlike traditional psychotherapists.
