OBJECTIVE: The SFB-SUI is an 8-item symptom inventory for patients with stress urinary incontinence (SUI). It generates both a symptom-frequency score and a symptom-bothersomeness score which describes symptom-linked psychological distress. The purpose of this presentation is to report the initial psychometric performance of the UK version of the SFB-SUI. METHODS: The SFB-SUI was included in a cross-sectional, descriptive health outcomes study among female care-seekers at 17 large primary care clinics in the UK. 2400 women 18 to 91 years of age took the survey while waiting to be seen by their doctors. Twenty-two percent (n=538) of those participating reported symptoms of SUI. Thirty percent (n=733) reported no urinary symptoms at all, and the remaining 48% reported a variety of other urinary symptoms, including mixed stress and urge UI. Other measures included the Incontinence-specific Quality of Life (I-QOL), the Scale for Activity Interference and Limitation (SAIL), and other descriptive variables. Reproducibility was not possible within the study design. RESULTS: The UK version of the SFB-SUI demonstrated internal consistency (α=0.74 and 0.79 for symptom-frequency and symptom-bothersomeness scores, respectively) as well as the ability to discriminate between self-reported levels of SUI severity (mild/moderate/severe, p<0.01) and severity based on the frequency of leakage (p<0.001). As predicted, the symptom-bothersomeness scores were correlated with activity restriction (0.51, p<0.001; by the SAIL). The SFB-SUI scores showed a good association with the I-QOL (0.27 to 0.43, p<0.001). CONCLUSION: The SFB-SUI functions well in distinguishing between levels of stress UI severity. The convergent properties between the two SFB-SUI scores and the quality of life and activity limitation measures indicate that each score is addressing the intended domains. This 8-item measure is extremely low in patient and study burden and provides a good option for describing SUI patient symptoms and symptom-related distress in community studies as well as clinical trials.
