ABSTRACT
There were two versions of the DSM published during the 1980s. The DSM-III was published in 1980 and the DSM-III-R (a revised version of DSM-III) was published in 1987. The versions of the DSM-III departed sig nificantly from both DSM and DSM-II. These earlier editions of the DSM mainly included abstract diagnostic terms and theoretical concepts. As such, its usefulness as a diagnostic tool was somewhat limited. The newer ver sions of the DSM, however, included significantly more information about symptomology, timing of onset, and descriptions of behaviors indicative of the disorders included.
