Development and Feasibility of the Portuguese Version of the ICIQ-bladder Diary as a Mobile Application

Lower urinary tract symptoms, including overactive bladder and urinary incontinence, are commonly assessed using bladder diaries. These diaries provide structured information on urinary frequency, voided volumes, fluid intake, urgency episodes, and incontinence events, supporting clinical assessment and treatment monitoring. Paper bladder diaries may be difficult to complete and interpret, which can limit their use in routine clinical practice. Electronic versions may improve completion, data quality, and interpretation efficiency.

This study aims to evaluate the feasibility and acceptance of a Portuguese electronic version of the International Consultation on Incontinence Questionnaire Bladder Diary (ICIQ-Bladder Diary) developed as a mobile application integrated into the My São João App. The electronic diary follows the structure of the validated Portuguese version of the ICIQ-Bladder Diary and records information over a 3-day period, including fluid intake, urinary frequency, voided volumes, urgency, incontinence episodes, and pad use.

The study will be conducted at the Pelvic Floor Rehabilitation Unit of ULS São João as a single-arm feasibility study. Adult participants with overactive bladder and/or urinary incontinence who have previous experience completing paper bladder diaries and who use smartphones in daily life will be recruited consecutively during routine consultations.

At the baseline visit, the investigators will collect demographic and clinical information, including previous experience with smartphone use and health-related mobile applications. Participants will complete condition-specific questionnaires and health-related quality-of-life measures. The investigators will provide training on installation and use of the electronic bladder diary application. Participants will then complete the diary for 3 consecutive days.

At the follow-up visit, the investigators will assess diary completion and collect participant feedback regarding usability, acceptability, and preference for the electronic diary format. Application quality will be evaluated using the Portuguese version of the User Mobile App Rating Scale (uMARS).
