Chronic Obstructive Pulmonary Disease (COPD) is a disease characterized by restriction of airflow in airways. Smoking is a major risk factor for disease. Other factors are air pollution from fuels, industrial dust, chemical agents and genetic causes. Main symptoms are shortness of breath, chronic cough with or without sputum and rapid fatigue. Chronic obstructive pulmonary disease /COPD/ is a source of stress and anxiety, due to severity of disease, need for long-term treatment and detachment from social life. Study cohort consisted of 124 patients with a diagnosis of COPD and a control group of 162 without lung disease. Persons studied are over 18 years of age, of different sexes, of Bulgarian ethnic origin and different family and social status. Chronic obstructive pulmonary disease is a disease of increasing social importance and, according to forecast of WHO, by 2030 it is expected to become third leading cause of death in world. Aim of pilot study was to determine influence of some personal risk factors (anxiety and type D personality in dimensions: "negative affectivity" and "social inhibition") on quality of life and social adaptation of patients with COPD.
