Abstract

No instrument is available to assess the impact of faecal incontinence (FI) of quality of life for Chinese-speaking population. The purpose of the study was to adapt the Faecal Incontinence Quality of Life Scale (FIQL) for patients with colorectal cancer, assess the factor structure and reduce the items for brevity. A sample of 120 participants were enrolled. Internal consistency, test-retest reliability, and convergent and contrasted-groups validity were assessed. Construct validity was analysed using an exploratory and confirmatory factor analyses (CFA). The internal consistency (Cronbach's α of the total scale and four subscales = 0.98 and 0.97, 0.96, 0.92, 0.82 respectively), test-retest reliability (intraclass correlation coefficients ≥.98 for all scales with p < .001) and significant correlations of all scales with selected subscales of the Medical Outcomes Study 36-Item Short-Form Health Survey and the Wexner scale suggested satisfactory reliability and validity. The severe FI group (with a Wexner score ≥9) scored significantly lower on the scale than the less severe FI group (with a Wexner score <9) did (p < .001). The CFA supported a two-factor structure and demonstrated an excellent model fit of the 15-item abbreviated version of the FIQL-Chinese. The FIQL-Chinese has satisfactory validity and reliability and the abbreviated version may be more practical and applicable.
