Criterion validity, test‐retest reliability and sensitivity to change of the St George urinary incontinence score

OBJECTIVE To assess the criterion validity, test‐retest reliability and the sensitivity to change after treatment of the St George Urinary Incontinence Score (SGUIS). PATIENTS AND METHODS Women presenting with urinary incontinence completed two SGUIS tests one week apart. A frequency‐volume chart (FVC) was completed before the first attendance and the women had a 1‐h pad test before treatment. Patients were treated conservatively under the care of a urogynaecologist or nurse continence advisor, or surgically with an open or laparoscopic colposuspension. After treatment, the SGUIS, FVC and 1‐h pad test were repeated. RESULTS The SGUIS correlated moderately well with the number of leaks per week (Spearman's r = 0.610, 95% confidence interval 0.516–0.689, P
