A total of 261 patients treated for drug addiction, 131 on a drug-free treatment and the remaining 130 patients received a drug regime, of which 113 were, according to the Prochaska and Decrement¡¯s Transtheorical Model, in a initial phase of the treatment (from 15 days to 6 months of treatment) and 148 in a maintenance phase in drug treatment (> 6 months), were psychopathologically assessed using the SCL-90-R (Derogatis, 2002). A field study with a 2 X 2 design (treatment: drug-free vs. drug-regime) and (treatment phase: initial phase vs. maintenance in drug treatment) was carried out. The results support the hypothesis of a dual diagnosis, that is, the comorbidity of psychopathology and drug addiction. On the whole, treatment for drug addiction had a significant impact on reducing associated psychopathology. Finally, the results are discussed in the light of the implications for the treatment of drug addiction. %K Psychopathology %K Drug addiction %K Drug-free programme %K Antagonists %K agonists %K Dual diagnosis. %U http://webs.uvigo.es/sepjf/index.php?option=com_docman&task=doc_download&gid=21&Itemid=110&lang=en
