CIDI diagnoses of BZD dependence

The substance use section of the CIDI was administered to 92 () of the respondents by telephone. Table 5 shows the number of people interviewed who met DSM3R or ICD10 criteria for BZD dependence. The majority of those interviewed () had never met either criteria for BZD dependence while the remaining 26 had met either or both criteria in their lifetime. Five participants met criteria for a diagnosis of BZD dependence on ICD10 and DSM3R in the month prior to interview.

Version 1.0 of the CIDI was used in the interviews. This version was designed to give diagnoses according to the final draft of ICD10. There were significant changes from the final draft to the published edition of the ICD10. Scoring of the CIDI was therefore altered to reflect the published edition of ICD10 [World Health OrganizationWorld Health Organization1992]. It should be noted that the changes from the final draft to the published edition made the criteria much more conservative. If the ICD criteria as stated in the final draft were applied, 25 respondents would have met criteria for a diagnosis of BZD dependence. The published ICD10 functions as a conservative subset of DSM3R as all eight people meeting ICD criteria also meet DSM3R criteria.
