"Erudite and well written, this book is a general 'how-to' use cognitive therapy techniques with people diagnosed as psychotic... This text's emphasis on the 'C' rather than 'B' aspect of CBT and its diagrammatic use of formulations set it apart." - Guy Holmes, Mental Health Today, June 2004"Morrison et al.'s book clearly presents the development of cognitive theory and therapy for psychosis in an engaging and accessible way. Suitable for newcomers to cognitive therapy, it will appeal to students and seasoned therapists, as well as those wishing to brush up on their cognitive therapy skills." - Kelly Vincent, European Journal of Psychotherapy and Counselling, Vol. 10, No. 3, September 2008
