Abstract
In this paper psychopathology of opiate addicts inside and outside treatment is described. Subjects were sampled in a low-threshold methadone programme (n = 93), two in-patient settings (n = 167) and outside treatment (n = 82). The Composite International Diagnostic Interview was used for the assessment of psychopathology. Results, in terms of DSM-III-R prevalence, are presented for the total group of respondents and for the three subgroups. After adjustment for differences in demographic characteristics it appeared that more subjects applying for in-patient treatment reported at least one psychiatric disorder compared with the two other groups. The subjects applying for the methadone programme reported least psychopathology. The results are discussed.
