ABSTRACT

Objective:

To adjust the wording and to examine the validity and reliability of the Chinese traditional version of the Body Image Scale (BIS) in patients with rectal cancer.

Methods:

Totally 180 patients pathologically diagnosed with rectal cancer were selected.The obtained data were divided equally into two parts.Half of them was for item analysis and exploratory factor analysis, and the other half was for confirmatory factor analysis and internal consistency reliability.The criterion validity was tested with the Quality of Life Questionnare-Core30 (QLQ-C30).Twenty-five patients were retested for test-retest reliability with 2 week interval.

Results:

Two factors were retained after exploratory factor analysis, which could explain 69.1% of the total variation.And the result of confirmatory factor analysis was that the structure of the scale was stable and achieved goodness of fit (χ2/df=2.32, CFI=0.96, NFI=0.93, IFI=0.96, TLI=0.94, RMSEA=0.078).The scores of total scale and two factors were negatively correlated with the scores of five function domains and overall quality of life of QLQ-C30 (r=-0.27——0.54, Ps<0.05).In total scale, Cronbach' s α coefficient of total scale was 0.92, while test-retest reliability was 0.88.

Conclusion:

The Chinese version of BIS showed good validity and reliability for assessment of body image in Chinese patients with rectal cancer.
