Abstract
Aims
To develop and validate a measure of patient satisfaction with treatment in overactive bladder: the Overactive Bladder Satisfaction Questionnaire (OAB‐S).
Methods
Development of the questionnaire included a comprehensive literature review, development of a conceptual model, item elicitation and cognitive debriefing interviews with US‐English and US‐Spanish patients, and assessment of the questionnaire's translatability in other languages. Psychometric validation of the questionnaire was run on a longitudinal, non‐randomized study involving 201 OAB patients. Analyses included construct validity, concurrent validity, tests of reliability, known‐group validity, and responsiveness (exploratory).
Results
The OAB‐S is a patient‐completed questionnaire including five scales: OAB Control Expectations (ten items); Impact on Daily Living with OAB (ten items); OAB Control (ten items); OAB Medication Tolerability (six items); and Satisfaction with Control (ten items) and five single‐item overall assessments of patient's fulfillment of OAB medication expectations, interruption of day‐to‐day life due to OAB, overall satisfaction with OAB medication; willingness to continue OAB medication and improvement in day‐to‐day life due to OAB medication. The hypothesized structure of the questionnaire was supported by statistical analyses. Internal consistency reliability coefficients (ranging from 0.76 to 0.94) and test‐retest reliability coefficients (ranging from 0.72 to 0.87) were good for all dimensions. All dimensions except tolerability discriminated well according to self‐reported OAB severity level and incontinence status.
Conclusion
The OAB‐S is a valid, comprehensive instrument to assess satisfaction with treatment of OAB based on independent scales that have demonstrated satisfactory psychometric performance. Neurourol. Urodynam. 27:179–190, 2008. © 2007 Wiley‐Liss, Inc.
