 Some believe that memories of SRA are solely iatrogenically implanted memories from suggestive therapeutic techniques, though this has been criticized by Daniel Brown, Alan Scheflin and Corydon Hammond for what they argue as over-reaching the scientific data that supports an iatrogenic theory.Others have criticized Hammond specifically for using therapeutic techniques to gather information from clients that rely solely on information fed by the therapist in a manner that highly suggests iatrogenesis.Skeptics claimed that the increase in DID diagnosis on the 1980s and 1990s and its association with memories of SRA is evidence of malpractice by treating professionals.
