Abstract
INTRODUCTION: The Uterine Fibroid Symptom and Health-related Quality of Life (UFS-QOL) questionnaire is a validated tool in English language to assess treatment outcomes for women with fibroids. We performed a Chinese (traditional) translation and cultural adaptation of it and evaluated its reliability, validity, and responsiveness. METHODS: Overall, 223 Chinese women aged ≥18 years with uterine fibroids self-administered the UFS-QOL, Short-Form Health Survey-12, pictorial blood loss assessment chart (PBAC), and a visual analogue scale (VAS) on fibroid-related symptom severity. Demographics and haemoglobin levels were recorded; physical examination and ultrasound for size of fibroids were performed. Half of the women were followed up 6 months later for responsiveness. RESULTS: Cronbach's alpha coefficients ranged from 0.706 to 0.937, demonstrating high internal reliability. The intra-class correlation coefficients to measure test-retest reliability implied excellent stability of symptom scores (0.819, P<0.001), health-related quality of life scores (0.897, P<0.001), and all subscales (range 0.721-0.870, P<0.001). Convergent validity was demonstrated by positive correlations between the findings of various symptom severity assessment tools (PBAC, VAS on fibroid-related symptoms severity) and the symptom severity domain of Chinese UFS-QOL. In addition, there were positive correlations between health-related quality of life scores of Chinese UFS-QOL and the corresponding subscales of the Short-Form Health Survey-12. Responsiveness was shown by reduction of symptom severity scores and improvement of health-related quality of life scores after treatment. CONCLUSIONS: The Chinese version of the UFS-QOL is valid, reliable, and responsive to changes after treatment.
