The development of a patient-reported outcome measure for real-time symptom assessment in a population with functional urologic complaints-A focus group study.

Aims: In the current diagnostic process for overactive bladder syndrome (OAB), biased retrospective questionnaires are often used. There is a need for a new assessment tool that embraces the heterogeneity of the OAB complex. A momentary assessment tool, the Experience Sampling Method (ESM) is promising, capturing random repetitive measurements during the day in the context of daily life and is capable to measure potential contextual triggers and psychological aspects.
