Introduction:
The Breast Module (BR23) is increasingly being used worldwide in breast cancer research. This study evaluates the appropriateness of the translated version (i.e. BR23-Malay version) as a useful tool for the Malaysian population who could understand Malay, and examines the reliability and validity of the BR23-Malay version.
Methods:
This was a prospective study involving 68 Malaysian women who could understand Malay very well. They answered the BR23-Malay version at two evaluation points--three and ten weeks following surgery for breast cancer. Internal consistency, test-retest intraclass correlation coefficients (ICC), effect size index, sensitivity and discriminity of the scale were calculated.
Results:
Internal consistencies were acceptable for the functional domains (0.87 for body image; 0.84 for sexual functioning) and symptomatology domains (0.82 for systemic therapy side effect; 0.82 for breast symptoms; 0.70 for arm symptoms). Test-retest ICC ranged from 0.26 to 1.00. Sensitivity of the scale was observed in all domains except sexual functioning.
Conclusion:
The Malay version of BR23 is a suitable tool to measure the functional and symptomatology domains of women diagnosed with breast cancer.
