The Thorn Initiative was put together by a group of people, most of whom were researchers who had conducted randomised controlled trials on various kinds of social treatments. Isaac Marks had worked on assertive community treatment (ACT), whereas my experience was in family work for schizophrenia, as was that of Nick Tarrier. In addition, Tarrier had carried out a recent trial of cognitive approaches to reducing delusions and hallucinations. It was rather like trying to turn an assemblage of prima donnas into a chorus, and it is a tribute to the personal qualities of Jim Birley that he succeeded in this seemingly impossible task.
