Development of questionnaires to measure patient preferences for intranasal corticosteroids in patients with allergic rhinitis.

OBJECTIVE: To develop a questionnaire to evaluate preferences for attributes of intranasal corticosteroids (INSs) in clinical trials with allergic rhinitis (AR) patients. STUDY DESIGN AND SETTING: Established questionnaire development practices were used, including performance of a literature review and use of patient and physician focus groups, cognitive debriefing interviews, and pilot testing before validation. RESULTS: Findings from patient and physician focus groups suggest that sensory attributes are relevant to AR patients when choosing INSs. Physician focus groups identified the need for 2 distinct preference instruments, a clinical trial patient preference questionnaire (CTPPQ) and a clinical practice preference questionnaire (CPPPQ). A pilot study suggests that the CTPPQ is capable of discriminating between 2 INSs in the clinical trial setting. CONCLUSIONS: Initial findings suggest that items in the CTPPQ and CPPPQ are easy to understand and relevant to patients. Further validation studies with larger sample sizes are needed to assess the psychometric properties of both questionnaires. EBM RATING: B-20.
