Introduction: Comorbidity is a term defined as the presence of two or more conditions occurring either at the same time or having a close relationship to the same individual. World Health Organization (WHO) define it as the "co-occurrence in the same individual of a psychoactive substance use disorder and another psychiatric disorder". Progressive deinstitutionalisation, despite indisputable benefits and improvement of life quality in psychiatric patients, resulted in appearance of new burdens, such as deterioration of family life. Furthermore, wide availability of alcoholic beverages and drugs in communities where the patients live, led comorbid substance abuse disorders to emerge as one of the biggest challenges in the modern psychiatry. There is a limited amount of data concerning the background of the patients with a dual diagnosis, available in the literature, and therefore our aim was to create a sociodemographic profile of such individuals.
Materials and methods: The study was conducted among the patients treated in a drug rehabilitation centre of the Upper Silesian Association "Familia" in Gliwice, Poland using authors' own questionnaire, consisting of 75 items. The study group consisted of 9 females and 91 males (n=100), average age of the patients equalled 29.7 years (95%CI: 28.5-31 years; min/max value: 20/48 years), all the patients had an established dual diagnosis.
Outcomes: 66% of the study group was single, with permanent residency, living with family either in city (47%) or in village (19%). Remaining 34% was spread through the other options (1-4%), with the highest percentage in "single, with permanent residency, living alone in the city" (4%).
Conclusions: Obtained data, demonstrated high homogeneity among the patients with a dual diagnosis in terms of a socio-demographical profile.
