Effects of scoring norms on adolescent psychiatric drug users' and nonusers' MMPI profiles.

The present study compared the effects of scoring norms on adolescent psychiatric inpatient drug users' and nonusers' MMPI profiles. The results indicated that regardless of drug usage or nonusage the application of adolescent norms yielded less pathological profiles than did the use of adult norms. A further finding was that Scale O, Social Introversion, is the only clinical scale from differentiated users' from nonusers' profiles.
