Relative risk of adolescent drug abuse: Part II. Intrapsychic variables

The total sample size for the study of intrapsychic variables was 252 (152 non-drug users and 100 life-time users including 69 current users). Using a multiphasic personality questionnaire, the Eysenck personality inventory and an orientation questionnaire, the authors found that high orientation, extraversion, anxiety and psychopathic deviate scores were associated with a relative risk of drug use. No significant difference is reported between the mean scores of users and non-users on mania, paranoia, depression, schizophrenia, hysteria and neuroticism.
