There are no reliable and valid instruments in Mexico for breast cancer patients. Our objective was to measure reliability and validity of a Spanish version of the FACT-B (Functional Assessment of Cancer Therapy-Breast) questionnaire in Mexican population.
The translation of the questionnaire was reviewed and minor changes were made. The instrument was applied to 142 patients recently diagnosed with breast cancer. It was applied to 105 for the second time, and to 75 for the third time. An analysis of item discrimination was made. The questionnaire's reliability was determined by Cronbach's alpha. Concurrent validity was determined by an analysis of correlations between the instrument's scales and EORTC's QLQ C-30 y BR-23 scales.
The five FACT-B subscales were reliable, their alpha coefficients varied between 0.65 and 0.82. The entire scale obtained a value of 0.87. The correlation analysis between FACT-B and EORTC QLQ C-30 subscales indicated that the same construct was being evaluated.
FACT-B is a valid, reliable and sensitive instrument to measuring quality life in Mexican breast cancer patients.
在墨西哥，针对乳腺癌患者尚无可靠且有效的评估工具。我们的目标是评估西班牙文版癌症治疗功能评估量表-乳腺癌（FACT-B）在墨西哥人群中的信效度。
对问卷翻译进行审核并做了细微修改。该工具应用于142例新诊断的乳腺癌患者，第二次应用于105例患者，第三次应用于75例患者。进行了项目区分度分析。问卷的信度由克朗巴哈系数确定。通过分析该工具各量表与欧洲癌症研究与治疗组织（EORTC）的QLQ C-30和BR-23量表之间的相关性来确定同时效度。
FACT-B的五个子量表是可靠的，其系数在0.65至0.82之间变化。整个量表的值为0.87。FACT-B与EORTC QLQ C-30子量表之间的相关性分析表明，评估的是相同的结构。
FACT-B是评估墨西哥乳腺癌患者生活质量的有效、可靠且敏感的工具。
