Little consensus exists on the risk of benzodiazepine (BZD) dependence. We investigated how often BZD dependence and related concepts have been defined in the literature on BZD effects in humans. In addition, the definitions of BZD dependence were compared in order to assess the similarity of contents. From a total of 250 papers (published between 1988 and 1991) 51 provided 126 dependence-related definitions. Six studies referred to the DSM definitions and one to the WHO definition. The obsolete concept of addiction was frequently defined (n=13), with little consensus about its meaning. Psychological and physical dependence were defined fairly often (n=29), also with low levels of consensus. We conclude that the discussion on the risk of BZD dependence would be well-served by attempting to improve consensus first. This may lead to more meaningful data on the incidence, prevalence and relevant co-factors of BZD dependence. An outline for criteria for benzodiazepine dependence is presented.
