Transcultural translation and validation of the FIGO Assessment Scoring System (FASS) to Portuguese language.

Introduction And Hypothesis: Our aim was to validate the Brazilian Portuguese version of the International Federation of Gynecology and Obstetrics (FIGO) Assessment Scoring System (FASS) to identify and quantify signs and symptoms related to pelvic floor dysfunction.

Methods: One hundred and seventy-nine women aged 18-82 (47.68 ± 14.42) years participated in this validation study. Collected data included a sociodemographic and clinical questionnaire, application of the FASS, and physical examination using the Pelvic Prgan Prolapse Quantification (POP-Q) system. The translation and cross-cultural adaptation were performed following the international methodology. The psychometric properties tested were criterion validity, construct validity, stability, and reliability. For this purpose, the comparison with POP-Q findings and between symptomatic and asymptomatic patients, test-retest and internal consistency (Cronbach's alpha) were used, respectively. The intraclass correlation coefficient (ICC) was calculated to assess the level of agreement between evaluations (inter- and intraobservers). P < 0.05 was considered statistically significant.

Results: The calculated Cronbach's alpha coefficient was 0.76, indicating strong reliability for the validation sample. Symptomatic women had different scores on all FASS items as well as total score when compared with asymptomatic women (p < 0.001). Intraobserver coefficient ranged from 0.91 (urinary symptoms) to 0.98 (FASS total score), indicating excellent concordance level in all items. Interobserver coefficient ranged from 0.47 (intestinal symptoms) to 0.90 (FASS total score), indicating moderate to excellent correlation.

Conclusions: The psychometric properties tested in the FASS Portuguese version proved to be a valid and reliable for evaluating signs and symptoms related to pelvic floor function in Brazilian women.
