Depressive Symptoms, Anxiety, Insomnia, and Sexual Quality of Life in Patients with Chronic Obstructive Pulmonary Disease from the Podlaskie Voivodeship, Poland: A Cross-Sectional Pilot Study

This pilot study indicates a substantial within-sample psychological burden in patients with COPD and suggests that these outcomes are closely associated with subjective symptom burden. Given the small sample size, marked group imbalance, cross-sectional design, and lack of objective COPD severity measures, the findings should be interpreted as exploratory and require confirmation in larger multicenter studies.
