Just weeks before the long-awaited publication of a new edition of the so-called bible of mental disorders, the federal government’s most prominent psychiatric expert has said the book suffers from a scientific “lack of validity.”
The expert, Dr. Thomas R. Insel, director of the National Institute of Mental Health, said in an interview Monday that his goal was to reshape the direction of psychiatric research to focus on biology, genetics and neuroscience so that scientists can define disorders by their causes, rather than their symptoms.
While the Diagnostic and Statistical Manual of Mental Disorders, or D.S.M., is the best tool now available for clinicians treating patients and should not be tossed out, he said, it does not reflect the complexity of many disorders, and its way of categorizing mental illnesses should not guide research.
“As long as the research community takes the D.S.M. to be a bible, we’ll never make progress,” Dr. Insel said, adding, “People think that everything has to match D.S.M. criteria, but you know what? Biology never read that book.”
