However, the available mental disorders prevalence data is characterized by a wide range of estimates (6-42\% for depression, 2-96\% for anxiety). The studies already published have methodological limitations, including relying on solely on psychometric instruments, lack of psychiatric examination.Aim: Investigate the prevalence of mental disorders in COPD patients.Methods: In multicenter study sample consisted of 122 COPD in- and outpatients receiving treatment in 4 Moscow hospitals (male n=97; mean age 66,5{\textpm}9,82 yr.). All participants were examined by pulmonologist, clinically interviewed by psychiatrist, and completed series of psychometric tests (HADS, BDI).Results: Clinical examination identified depressive disorders in 23.8\% patients, while psychometric data showed higher estimates (34.4\%). Anxious, neurotic and stress-related disorders were detected in 19.7\% cases. A large number of organic/somatogenic mental disorders was also registered: asthenia (47.5\%) and mild cognitive dysfunction (preclinical stage of dementia {\textendash} 32.8\%). In 2 patients (1.6\%) clinical dementia was registered. Asthenia and cognitive dysfunction were more common in patients with higher severity of respiratory failure (III degree - 64.4\%), airflow obstruction (III, IV - 39.1\% of patients), and in older patients.Discussion: Direct psychiatric examination showed significantly less depression rates in COPD patients than was evaluated by a psychometric instrument. This discrepancy may be due to the overlap of COPD symptoms and psychometrically registered depression symptoms ({\textquotedblleft}scale symptom contamination{\textquotedblright}). High prevalence of organic mental disorders was revealed in COPD sample.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/42/Suppl_57/P1539}, eprint = {https://erj.ersjournals.com/content/42/Suppl_57/P1539.full.pdf}, journal = {European Respiratory Journal} }
