Two prominent authors of a 1999 book teaching family doctors how to treat psychiatric disorders provided acknowledgment in the preface for an “unrestricted educational grant” from a major pharmaceutical company. But the drug maker, then known as SmithKline Beecham, actually had much more involvement than the book described, newly disclosed documents show. The grant paid for a writing company to develop the outline and text for the two named authors, the documents show, and then the writing company said it planned to show three drafts directly to the pharmaceutical company for comments and “sign-off” and page proofs for “final approval.” The 269-page book, “Recognition and Treatment of Psychiatric Disorders: A Psychopharmacology Handbook for Primary Care,” is so far the first book among publications, namely medical journal articles, that have been criticized in recent years for hidden drug industry influence, colloquially known as ghostwriting.
