Moving Beyond p-Values: MCID for OAB-V8 8 and ICIQ-SF in Patients With OAB

Moving Beyond p-Values: Minimal Clinically Important Difference for Overactive Bladder Questionnaire - Version 8 and International Consultation on Incontinence Questionnaire - Short Form in Patients With Overactive Bladder Syndrome

The goal of this study was to determine the Minimal Clinically Important Difference (MCID) for the Overactive Bladder Questionnaire-Version 8 (OAB-V8) and the International Consultation on Incontinence Questionnaire- Short Form (ICIQ-SF) in people with Overactive Bladder Syndrome (OAB).

104 patients with OAB will receive common behavioral therapy and transcutaneous posterior tibial nerve stimulation (TPTNS) for 12 weeks. OAB-related symptoms and quality of life (QoL) will be assessed with the OAB-V8 and ICIQ-SF baseline and post-intervention. The receiver operating characteristic (ROC) analysis and the Gamma coefficient will be employed to determine sensitivity.

Inclusion Criteria:

• individuals diagnosed with urge and mixed urinary incontinence symptoms or with OAB symptoms only (no history of urinary incontinence),
• women over 18 years of age.

Exclusion Criteria:

• patients who did not give consent to participate in the study,
• not understanding the instructions given by the researcher,
• pregnancy or planning a pregnancy in the near future,
• urinary tract infection or kidney stones,
• pelvic organ prolapse of grade II or higher,
• stress-type urinary incontinence,
• neurogenic bladder,
• use of a pacemaker,
• epilepsy,
• peripheral neuropathy.
