Aim. Current study aimed to adapt and evaluate the psychometric properties of Russian versions of Patient Health Questionnaires 2 and 9 (PHQ-2 and PHQ-9) used for detection of depression in general medical practice worldwide. Material and methods. Questionnaires were translated into Russian and adapted with regard to linguistic features of population. A study was performed on a sample of 193 patients (130 female, 63 male, mean age 34,6±11,4), who attended general practitioners in outpatient practice department of NRC for Preventive Medicine. Patients filled in PHQ-2 and –9 questionnaires in presence of clinical psychologist and then assessed for depression by a psychiatrist (using ICD-10 criteria). Results. The optimal measures of sensitivity and specificity corresponded to cut-off scores of 3 for PHQ-2 (66,2% and 87,4% respectively) and 10 for PHQ-9 (68,9% and 93,3% respectively). Russian questionnaires were found to success in sensitivity, specificity and their positive predictive values are comparable to similar research data reported in literature.
