Np. Fieldman et al., DIMENSIONS OF SELF-CONCEPT - A COMPARISON OF HEROIN AND COCAINE ADDICTS, The American journal of drug and alcohol abuse, 21(3), 1995, pp. 315-326
Two groups of drug users on an inner-city inpatient drug detoxificatio
n unit were studied: 42 heroin addicts and 47 cocaine addicts. The two
groups were compared on personality disorder diagnoses, personality t
raits, and demographic variables. Cocaine and heroin addicts scored si
milarly on: 1) number and kind of personality disorder diagnoses, with
the exception of antisocial personality; 2) all personality traits me
asured; 3) positive and negative temperament; 4) description of self-c
oncepts; and 5) positivity and negativity of self-concepts. It was als
o found that heroin addicts showed significantly higher levels of soci
al deviance than the cocaine group, with significantly more antisocial
personality disorder diagnoses, higher levels of social deviance, and
lower scores on a Propriety Scale. Character pathology was more heter
ogeneous among cocaine users. Heroin addicts had used significantly lo
nger and showed less educational and occupational achievement than the
cocaine group. Our results also suggest that personality psychopathol
ogy in drug addicts is associated with lower self-esteem, more negativ
e self-valuation, and longer duration of use.
