To develop and validate a measure of patient satisfaction with treatment in overactive bladder: the Overactive Bladder Satisfaction Questionnaire (OAB-S).
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).
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.
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.
