A new piece of evidence has been unearthed by Phyllis Vine of MIWatch that the Nemeroff/Schatzberg textbook was indeed ghostwritten by STI, Scientific Therapeutics Information. Somehow, Vine was able to unearth STI's "portfolio" of publications, even though the company has since removed the incriminating pages.
I suppose APA might still hold to its guns, presumably by arguing that STI did no more than help to coordinate the project, perhaps by funnelling funds from SmithKlineBeacham to the American Psychiatric Press. That would be a stretch.
You can look at the suppressed web page yourself here. It is filled with the usual suspects--mostly industry funded supplements of various medical journals, including the Journal of Clinical Psychiatry, the preeminent producer of pseudo-CME supplements. Aside from the Nemeroff/Schatzberg book, STI also displays a book on the management of lipid disorders and a book on fungal infections. Perhaps an enterprising reader of this blog will track down the funders and writers of those books.
This is all part of STI's portfolio. What is a "portfolio"? It is "A set of pieces of creative work collected by someone to display their skills, esp. to a potential employer." In this case, Nemeroff and Schatzberg got to not only claim the textbook as part of their own portfolios, but presumably they got paid for the honor. Niiiice.
