Validation of the Onset of Effect Questionnaire in Participants With Chronic Obstructive Pulmonary Disease.

ABSTRACT:

Background

Patient perception of medication onset of effect is important for adherence. Although the Onset of Effect Questionnaire (OEQ) has been validated in patients with asthma, it has not been evaluated in patients with chronic obstructive pulmonary disease (COPD). This study evaluated the COPD-OEQ in patients with COPD.

Methods

Two analyses (qualitative and quantitative) were conducted to assess the content validity and psychometric properties of the COPD-OEQ in participants with COPD. In the qualitative analysis, interviews assessed content validity by concept elicitation (CE) and cognitive interviewing (CI). CE included questions to understand patient experience related to onset of medication effect. CI included completion of the COPD-OEQ and assessment of the COPD-OE
