Patient satisfaction with the benefits of overactive bladder treatment: Exploration of influencing factors and development of a satisfaction assessment instrument

Patient‐reported outcome (PRO) instruments are useful for assessing treatment success in patients with overactive bladder (OAB). PROs such as the OAB Questionnaire (OAB‐q) and Patient Perception of Bladder Condition (PPBC) focus more on OAB symptoms than satisfaction. We describe the development of the Patient Satisfaction with Treatment Benefit (PSTB) questionnaire, and examine the face, content and criterion validity of this tool in a study of darifenacin treatment in OAB patients who expressed dissatisfaction with prior antimuscarinic therapy.
