Psychometric validation of the 1-month recall Uterine Fibroid Symptom and Health-Related Quality of Life questionnaire (UFS-QOL).

ABSTRACT: BACKGROUND:To evaluate the psychometric characteristics of the 1-month recall Uterine Fibroid Symptom and Health-Related Quality of Life questionnaire (UFS-QOL), including the Revised Activities subscale. METHODS:VENUS I and II were phase III, randomized, double-blind, placebo-controlled trials of ulipristal acetate in women with uterine fibroids (UF) and abnormal uterine bleeding. Women completed the 1-month recall UFS-QOL at baseline and after 12?weeks' treatment. Uterine bleeding was assessed via a daily diary (both studies); the Patient Global Impression of Improvement scale (PGI-I) was completed in VENUS II. Psychometric analyses examined internal consistency reliability and construct validity of the UFS-QOL; confirmatory factor analysis (CFA) compared model fit of the original and Revised Activities subscales. Analyses were conducted separately for VENUS I and II. RESULTS:One hundred and fifty-seven patients in VENUS I and 429 in VENUS II were included. Changes in mean Symptom Severity and health-related quality of life (HRQoL) scale scores indicated symptom burden reductions and HRQoL improvements. Cronbach's alpha coefficients were high at baseline and after 12?weeks' treatment (all ?0.76, meeting the >0.70 threshold), demonstrating strong internal consistency reliability. Correlations between UFS-QOL scores and bleeding diary responses (range: -0.35 to -0.63), and UFS-QOL scores and PGI-I responses (range: -0.48 to -0.70), ranged from moderate to strong after 12?weeks' treatment (all p?
