Dissociation : Volume 10, No. 2, p. 114-119 : Handwriting examination: Can it help in establishing authenticity in Dissociative Identity Disorder?
(Ridgeview Institute and the International Society for the Study of Dissociation, 1997-06) Somer, Eliezer, 1951-; Yishai, Ron
Questions with regard to the genuineness of amnesia and DID in forensic settings have been of considerable past concern in trials of accused criminals claiming amnesia, accused perpetrators of incest and psychotherapists accused of negligently implanting memories or creating DID symptoms. This study has used document examination methods to investigate 30 different manuscripts suspected to have been mailed by three alters of a DID patient. In the present single case study we have found that despite the striking differences between the three handwritings identified, single authorship of the documents could be established. We have also shown that these handwritings could not have been a result of conscious disguise, and we were thus able to determine the authenticity of the phenomenon. Forensic implications of these findings are discussed.
