Many of the books in the collection at the Institute's McLean Library were written by clinicians practicing at the Institute. From time to time, we try to highlight some of their published work. Here we offer a brief description of one of these publications, “Assessing Schizophrenic Thinking,” by faculty member Holly Johnston, PhD.

Johnston published the book in 1979 with her dissertation head and mentor Dr. Philip S. Holzman. The book provides a detailed description of the Thought Disorder Index, a measurement tool that Johnston developed for her PhD dissertation. She expanded and adapted this index from an older scale used at the Menninger Clinic in the 1950s, where Holzman had studied and taught before coming to Chicago in the 1970s.

Johnston’s book with Holzman builds on her previous research on schizophrenia. Both the Thought Disorder Index and the book have been cited frequently in subsequent publications right up to the present day.
