Differential Responses of Addicts and Non-Addicts on the MMPI

Summary An item analysis of MMPI responses of drug addicts and a matched control group was performed. Cross-validation procedures were used. The results identified nineteen (19) items which significantly differentiated the two groups. The authors feel that these items will be both useful in the identification of the drug addiction syndrome and develop insight into the understanding of conflict areas of the addict. It is suggested that these items can form a part of the diagnostic clinical interview.
