Use of Heroin Addiction Scale to Differentiate Addicts from Rehabilitation Clients

The profile patterns of addicts and rehabilitation clients using the MMPI and the heroin addiction scale (He) were compared to determine differences and to extend the applicability of the He scale. The subjects were a group of addicts, 76 males and 21 females, and a group of vocational rehabilitation clients, 56 males and 14 females. Significant differences on scale elevations between the two groups were found, with the heroin addicts obtaining substantially higher elevations. The He scale successfully discriminated addicts from non-addicts and in fact was the best predictor of group status, i.e., addict versus non-addict, among all the variables.
