SYMPTOM QUESTIONNAIRES

Morning symptoms were analyzed with the Early Morning Symptoms of COPD Instrument.(27) It was designed to measure three concepts of interest in patients with COPD: 1. occurrence and severity of six morning symptoms ("Did you feel any of the following symptoms this morning?: cough, wheezing, shortness of breath, chest tightness, chest congestion, or difficulty expectorating?") and general severity of symptoms ("If so, what was the intensity of the symptom: mild, moderate, intense, or very intense?"); 2. impact of those symptoms in terms of the limitation of morning activities ("To what extent did the symptoms limit your activities this morning?"); and 3. use of rescue medication ("How many inhalations of the rescue medication did you use this morning?").

Nighttime symptoms were analyzed with the Nighttime Symptoms of COPD Instrument,(28) which is based on the Early Morning Symptoms of COPD Instrument(27) and measures the following concepts of interest: 1. occurrence and severity of six nighttime symptoms and their intensity; 2. impact of these symptoms in terms of nocturnal awakenings ("Did you wake up last night because of your COPD symptoms?"; and "How many times did you wake up because of your COPD symptoms?"); and 3. use of rescue medication ("How many inhala-tions of the rescue medication did you use last night?).
