First published in 1974, Obsessional States is a collection of original papers by clinical psychologists and psychiatrists that gave a comprehensive survey of thought on significant aspects of obsessional neuroses at the time. The symptoms of patients suffering from this kind of disorder are discussed in the light of contemporary theoretical frameworks, and the outcome of various treatments is examined.

There was much still to be learnt about obsessional disorders, and it was hoped that by reviewing the current evidence available and at the same time offering new information on the subject, the book would act as a stimulus to further research. Today it can be read in its historical context.
