Although pressurized metered dose inhalers (pMDIs) are widely used in the treatment of COPD, individuals with COPD often have errors in technique. Individuals\u2019 perceptions of the disease and their reactions can influence their health behaviors and medication adherence. This study was designed to investigate the relationship between pMDI use skill and COPD perception and reaction in individuals with COPD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      This descriptive and correlational study was conducted with 184 subjects treated at the Pulmonary Diseases Clinic. The Participants Information Form, the pMDI Skill Assessment Checklist, and the COPD Perception and Reaction Scale (COPD PRS) were used to collect data. Pearson correlation analysis was used to analyze the relationship between subjects\u2019 pMDI skill scores and their COPD PRS scores.
