Comparison of four groups of substance-abusing in-patients with different psychiatric comorbidity.
OBJECTIVE
Comparisons of different groups of dual patients are rare, yet potential differences could have therapeutic implications. In this study, four groups of psychiatric in-patients with substance use disorder were compared to each other: patients with no psychiatric comorbidity, patients with comorbid schizophrenia and patients with affective and personality disorder.


METHODS
Apart from sociodemographic, therapy-related variables and a detailed survey of their substance use, all subjects were assessed with BPRS and SCL-90-R.


RESULTS
No differences were found in the patients' demography, psychosocial adjustment and substance consumption career. Significant differences were found in regard to some therapy variables reflecting adherence to treatment and global outcome and to the level of psychopathology.


CONCLUSIONS
Both substance use and comorbid psychiatric disorder have a variable impact on distinct areas of patients' general condition and functioning. The group with comorbid affective disorder appeared to be the most difficult to treat and the therapeutic approach to this disorder deserves reconsideration.
