Validation of the Expanded Prostate Cancer Index Composite (EPIC) questionnaire translated to Portuguese. This is an evaluation tool of the effects of treatment on quality of life of patients with prostate cancer.
In order to translate and validate, several recommended methodological techniques in the literature were included: initial translation, synthesis of translation, board committee review and back translation. Sample included 40 patients with localized prostate cancer submitted to surgical retropubic radical prostatectomy from 2008 to 2010.
The internal consistency analysis of the scales of the questionnaire resulted in alpha Cronbach coefficients "very good" (> 0.9) and "good" (> 0.8) to 8 of 14 domains. The higher coefficients (0.94) were assigned to sexual score, subscales incontinence and sexual function. Post-operatory follow-up ranged from 3 to 35 months, median 18.7 months.
The Brazilian version of EPIC is reliable and valid, and is a useful tool to evaluate the impact of retropubic radical prostatectomy on quality of life of Brazilian patients with localized prostate cancer, in national and internationals studies.
验证已被译为葡萄牙语的扩展前列腺癌指数复合量表（EPIC）问卷。这是一种评估前列腺癌患者治疗对生活质量影响的工具。
为了实现翻译和验证，我们纳入了文献中推荐的几种方法学技术：初始翻译、翻译合成、委员会审查和回译。该样本包括 2008 年至 2010 年间接受经耻骨后根治性前列腺切除术的 40 例局限性前列腺癌患者。
问卷各量表的内部一致性分析得出，14 个领域中有 8 个领域的克朗巴赫 α 系数为“非常好”（>0.9）和“好”（>0.8）。更高的系数（0.94）被分配给了性评分、尿失禁和性功能子量表。术后随访时间为 3 至 35 个月，中位数为 18.7 个月。
巴西版 EPIC 是可靠和有效的，是评估经耻骨后根治性前列腺切除术对巴西局限性前列腺癌患者生活质量影响的有用工具，可用于国内和国际研究。
