A new 7-item overactive bladder symptom score was validated. This reliable and valid instrument accurately assesses overactive bladder symptoms in patients and can be used as a clinical tool.

Area of Science:

  • Urology
  • Clinical assessment
  • Patient-reported outcomes

Background:

  • Overactive bladder (OAB) significantly impacts quality of life.
  • Accurate symptom assessment is crucial for diagnosis and management.
  • Existing assessment tools may not capture all facets of OAB symptoms.

Purpose of the Study:

  • To validate a novel 7-item overactive bladder symptom score.
  • To establish the reliability and validity of the new OAB symptom score.

Main Methods:

  • A cohort of 84 participants (33 men, 51 women; median age 62) was recruited.
  • Participants included normal subjects, patients with lower urinary tract symptoms (LUTS), and those with OAB.
  • The 7-item questionnaire was administered twice to assess internal consistency, test-retest reliability, and discriminant validity.

Main Results:

  • The study included 33% OAB, 36% LUTS without OAB, and 25% normal subjects.
  • High internal consistency (Cronbach's alpha 0.80-0.83) and strong test-retest reliability (r=0.72-0.79) were observed.
  • Significant differences in scores among the three subgroups confirmed discriminant validity (p<0.01).

Conclusions:

  • The 7-item overactive bladder symptom score is a valid and reliable instrument.
  • The score effectively assesses all key aspects of overactive bladder.
  • This validated score can be utilized as a clinical tool for symptom assessment.
