    Frequently Asked Questions About the Overactive Bladder Questionnaires

What is the difference between the three questionnaires?

There are three questionnaires in the OAB Questionnaire Family. The choice of the most appropriate instrument will depend upon the intended use of the questionnaire and the specific research objectives.

  • OAB-q: The original version of the OAB-q was developed to assess symptom bother and health-related quality of life (HRQL) among patients with either continent or incontinent overactive bladder. The original OAB-q has an 8-item symptom bother scale and four HRQL subscales (coping, concern, sleep, social interaction), which are derived from 25 items. The original OAB-q should be used when the research objectives relate to assessing symptom bother as a study endpoint or when assessing specific aspects of OAB's impact on HRQL are desired, such as effects on sleep, social interaction, and so on.

  • OAB-q SF: A short form of the original OAB-q was derived to provide a "quick" assessment of symptom bother and global HRQL. This "short form," called the OAB-q SF, consists of a 6-item symptom bother scale and a 13-item HRQL scale. The OAB-q SF should be used when the assessment of symptom bother is desired, but may not be a primary or secondary endpoint or when a global assessment of HRQL, rather than specific domains of HRQL, is desired.

  • OAB Awareness Tool: The 8-item Symptom Bother scale of the original OAB-q was validated for use as an awareness tool to identify patients who may have bothersome OAB symptoms. The format and instructions of the OAB Awareness Tool were designed for screener use.
When selecting the questionnaire for your study, it is important to remember that with an increased number of questions, increased sensitivity is gained in the questionnaire. Additionally, should labeling claims be desired, questionnaire selection must match the desired outcome.

What differentiates the OAB-q from other condition-specific questionnaires such as the KHQ, IIQ, or I-QOL?

A range of well-validated condition-specific questionnaires are available for use among patients with symptoms of OAB. Questionnaires vary in terms of the domains assessed and the number of items assessing a specific domain. Depending upon the goals of the research or clinical question, one questionnaire may be preferable over another particularly if it assesses a desired domain that other questionnaires may or may not address adequately.

    Another distinguishing feature of each questionnaire involves the specific patient population for which it was designed and validated. Instruments should have demonstrated evidence of reliability and validity in the patient population under investigation (Leidy et al. 1999). A questionnaire shown to be valid in one population is not necessarily valid for use in a population with different demographic or clinical characteristics. Therefore, when choosing an instrument, it is critical to match the questionnaire with the intended study sample. Please see the table below summarizing Condition-Specific Health-Related Quality of Life Instruments for further information on relevant questionnaires.
