Responsiveness to the Portuguese version of the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) after stress urinary incontinence surgery.
OBJECTIVE
To evaluate the reliability and responsiveness (internal and external) of the Portuguese version of the ICIQ-SF. We assessed the responsiveness of the ICIQ-SF after surgical procedures for the treatment of stress urinary incontinence.


METHODS
Prospective open label study in 2 tertiary referral centers. Sixty-one patients of both genders (54 female and 7 male) were enrolled. Patients were treated using surgical procedures, mostly with synthetic sling (82%). Patients were assessed before surgery and at least 1 month postoperatively using the ICIQ-SF in its translated and validated Portuguese version. Patients also underwent pre-operative urodynamic tests, Stamey incontinence grading and pad usage assessments. After surgery, patients underwent stress tests, Stamey incontinence grading and pad usage assessments.


RESULTS
The mean age was 57.2 (+/- 11.6) years and the mean duration of follow-up was 7.2 months (+/- 4.5). Objective parameters such as urodynamic tests (by means of VLPP) and pad usage had significant correlation with changes in post-treatment scores on the ICIQ-SF (p = 0.0062 and p < 0.0001 respectively). The responsiveness expressed in terms of standardized effect sizes (SES) and standardized response means (SRM) was large for both questionnaires (p < 0.0001).


CONCLUSIONS
The results showed high responsiveness (large effect sizes I and II) for the Portuguese version of the ICIQ-SF, indicating that this instrument is suitable for measuring outcomes in clinical trials for Brazilian patients with stress urinary incontinence.
