Objective: Aim of this study was to study sociodemographic, clinical characteristics and extent of alcohol use disorder (AUD) among patients applied by probation. Methods: The file records of the 215 cases who gave at least one urine-blood sample applied to Izmir Ataturk Education and Research Hospital Addiction Unit Probation Policlinic at February 2010 have been assessed retrospectively. Sociodemographic characteristics, clinical char-acteristics of substance use and CAGE (Cut down, Annoyed, Guilty, Eye-opener) scores and blood %CDT (carbo-hydrate-deficient transferrin) results of cases were used to detect AUD. SPSS 15.0 program has been used for the statistical assessment. Results: The average age of the sample was 29.4±9.1 year and most of the patients were male (%99.5). The lifetime prevalence of substances was cannabis %99.5, ecstasy %17.2, benzodiazepine %11.6, cocaine %5.6, heroin %0.9 and inhalants %0.9. %10.2 patients were positive for urine samples. %8.8 patient were positive for cannabis and %3.2 were positive for benzodiazepine. Urine samples positive group had higher unemployment rates (χ2=8.72, p=0.003) and higher CAGE scores (χ2=5.08, p=0.024). %37.2 patients had positive %CDT and %25.6 patients had positive CAGE scores. Discussion: The most important finding of this study is that higher unemployment rates in urine positive group and high AUD rates in all patients. The relation-ship between unemployment and substance use show that social and employment rehabilitation programs with medical treatment is important. High AUD rates show the importance of evaluating alcohol use in treatment. [Anadolu Psikiyatri Derg 2011; 12(4.000): 253-257]
