Background: Chronic Obstructive Pulmonary Disease (COPD) is a multicomponent disorder. It has been found that the quality of life of these patients is highly impaired by physical and psychological alterations associated with the disease. There is a relationship between the perception of the disease and negative emotions such as anxiety, being three times more frequent in these patients. Aim: To investigate psychological factors predictive of quality of life in patients with COPD. Method: A cross-sectional study was conducted, 73 outpatients diagnosed with COPD participated. The SF-12 health questionnaire was used to measure quality of life, in terms of physical and psychological functioning; and the Hospital Anxiety and Depression Scale (HADS) was used to determine the level of anxiety and depression symptoms. In addition, the subjective assessment of the severity of their illness and the perception of limitation in their daily life were evaluated, using a Likert scale (1-4 points). A multiple linear regression model analysis was performed using the SPSS v25 software. Results: The average age of the sample was 67 ± 10.86 years, 58.9% women. The regression model (F (3, 25) = 25.16, p Conclusions: Include in the evaluation and treatment the assessment of psychological aspects such as the perception of the disease and emotional state can have a positive impact on the treatment of patients, thus greatly improving their quality of life.
