To validate the instrument Body Image Relationship Scale (BIRS) for Brazilian women with breast cancer.
The instrument was administered by trained interviewers to 139 women who used the Brazilian Unified Health System (SUS). All of them had been submitted to cancer treatments between 2006 and 2010. The instrument was validated considering internal consistency and reliability. In order to compare the techniques, the same factorial analysis as used in the original paper was carried out.
The Spearman-Brown correlation value was 0.8, indicating high internal reliability. The Cronbach's alpha found was 0.9, indicating a high level of internal consistency. Factorial analysis showed that four items had low factorial load and no discriminatory power, and another five items were relocated to other factors. When the instrument was applied, it showed variability to that of the original instrument.
The Brazilian version of the Body Image Relationship Scale (BIRS), named Escala de Relacionamento e Imagem Corporal (ERIC), showed evidence of adequate reliability and internal consistency, making this instrument suitable to be recommended for application to Brazilian women with breast cancer, despite some limitations.
验证适用于巴西乳腺癌女性的身体意象关系量表（BIRS）。
由经过培训的访谈者对139名使用巴西统一卫生系统（SUS）的女性进行该量表测试。她们均在2006年至2010年间接受过癌症治疗。从内部一致性和可靠性方面对该量表进行验证。为比较技术方法，进行了与原文相同的因子分析。
斯皮尔曼-布朗相关值为0.8，表明内部可靠性高。克朗巴哈系数为0.9，表明内部一致性水平高。因子分析显示，有4个项目的因子载荷低且无区分能力，另外5个项目被重新归类到其他因子。该量表应用时，与原量表相比存在差异。
巴西版身体意象关系量表（BIRS），即身体关系与意象量表（ERIC），显示出足够的可靠性和内部一致性，尽管存在一些局限性，但该量表仍适合推荐用于巴西乳腺癌女性。
