Two-point MMPI code-types of drug abusers in a psychiatric, residential, drug-free therapeutic community were obtained to identify the most frequent two-point codes of drug abusers and see if a large proportion of the protocols could be classified into a small number of two-point codes. Responses indicated that the 48/84 and 49/94 codes were most frequent, and 80.6% of the MMPI protocols could be classified into only seven two-point codes, 48/84, 49/94, 24/42, 89/98, 46/64, 78/87 and 28/82.
