suggest that a small number of clinicians diagnosing a disproportionate number of cases would provide evidence for their position though it has also been claimed that higher rates of diagnosis in specific countries like the United States may be due to greater awareness of DID. Lower rates in other countries may be due to artificially low recognition of the diagnosis. However, false memory syndrome per se is not regarded by mental health experts as a valid diagnosis, and has been described as "a non-psychological term originated by a private foundation whose stated purpose is to support accused parents," and critics argue that the concept has no empirical support, and further describe the False Memory Syndrome Foundation as an advocacy group that has distorted and misrepresented memory research. Children The rarity of DID diagnosis in children is cited as a reason to doubt the validity of DID, and proponents of both etiologies believe that the discovery of DID in a child who had never undergone treatment would critically undermine the SCM. Conversely, if children are found to develop DID only after undergoing treatment it would challenge the traumagenic model. , approximately 250 cases of DID in children have been identified, though the data does not offer unequivocal support for either theory. While children have been diagnosed with DID before therapy, several were presented to clinicians by parents who were themselves diagnosed with DID; others were influenced by the appearance of DID in popular culture or due to a diagnosis of psychosis due to hearing voices – a symptom also found in DID. No studies have looked for children with DID in the general population, and the single study that attempted to look for children with DID not already in therapy did so by examining siblings of those already in therapy for DID. An analysis of diagnosis of children reported in scientific publications, 44 case studies of single patients were found to be evenly distributed (i.e., each case study was reported by a different author) but in articles regarding groups of patients, four researchers were responsible for the majority of the reports. The initial theoretical description of DID was that dissociative symptoms were a means of coping with extreme stress (particularly childhood sexual and physical abuse), but this belief has been challenged by the data of multiple research studies. Proponents of the traumagenic hypothesis claim the high correlation of child sexual and
