Abstract
The Psychoactive Substance Abuse and Dependence (PSDA) section of the revised, 3rd edition of the American Psychiatric Association's Diagnostic and Statistical Manual for Mental Disorders (DSM‐III‐R) bears a close correspondence to the conceptualization of a dependence syndrome as posited by Edwards, Arif & Hodgson (1981). Further, DSM‐III‐R represents a major shift in psychodiagnostics. The present study investigated hypothesized properties of the dependence syndrome and examined the characteristics of DSM‐III‐R criteria with a sample of opiate users. Findings indicated general support for the unidimensional postulate of the dependence syndrome but did not support the weighting of syndrome elements within DSM‐III‐R. The implications of such findings for the proposed DSM‐IV are discussed.
