Objective: To compare the opinions of Canadian psychiatrists regarding dissociative disorder diagnoses with those of previously surveyed American psychiatrists.
Method: We sent a 1-page questionnaire to a stratified representative sample of 550 Canadian psychiatrists.
Results: Eighty percent of Canadian psychiatrists responded. Fewer than one-third replied that dissociative amnesia and dissociative identity disorder should be included without reservations in the DSM-IV; fewer than 1 in 7 felt that the validity of these diagnoses was supported by strong scientific evidence. French- and English-speaking Canadians had similar opinions. Overall, Canadians were significantly less accepting than Americans.
Conclusion: Both Canadian and American psychiatrists show little consensus regarding the diagnostic status or scientific validity of dissociative amnesia and dissociative identity disorder.
