目的：国际临床研究中与健康相关的生活质量终点的重要性强调了经过充分验证和转化的测量方法对于实现跨文化比较的重要性。美国国立卫生研究院 (NIH) - 慢性前列腺炎症状指数 (CPSI) 用于评估患有慢性非细菌性 NIH III 型前列腺炎的男性的症状和健康相关的生活质量。为了将其用途扩大到西班牙语患者，我们进行了翻译和语言验证。材料和方法：根据 2 个正向翻译、1 个协调版本、协调版本的反向翻译和 3 个双语专家独立审查的标准方法，将 9 项 NIH-CPSI 翻译成西班牙语。这种方法的目的是创建一个单一的通用西班牙语版本，让美国境内外的西班牙语母语人士都能接受。翻译过程结束后，西班牙语版本在阿根廷、墨西哥、西班牙和美国进行了预测试。分析患者的反应以确定必要的修改。使用 Cronbach's alpha 评估 CPSI 的内部一致性。采用皮尔逊乘积矩相关性评价结构效度。结果：数据收集自慢性前列腺炎患者，其中阿根廷15例，墨西哥15例，美国4例，西班牙3例。翻译结果在总体上和所有分量表中都具有很高的可靠性（克朗巴赫系数 α = 0.81 至 0.94），并且分量表彼此相关性良好（r = 0.76 至 0.97）。然而，患者在问题3中表示难以区分反应类别“a menudo”（“经常”）和“normalmente”（“通常”）。我们将“a menudo”修改为“muchas veces”（“大部分时间”），将“normalmente”修改为“casi siempre”（“几乎总是”），以提高反应类别的独特性。结论：西班牙NIH-CPSI具有较高的可靠性以及面部和构造对来自不同国家的讲西班牙语的男性的有效性。西班牙 NIH-CPSI 允许对患有慢性非细菌性前列腺炎的男性进行跨文化比较。
Purpose: The prominence of health related quality of life end points in international clinical research underscores the importance of well validated and translated measures to enable cross-cultural comparison. The National Institutes of Health (NIH)-Chronic Prostatitis Symptom Index (CPSI) assesses symptoms and health related quality of life in men with chronic nonbacterial, NIH type III prostatitis. To expand its use to Spanish speaking patients we performed a translation and linguistic validation.Materials and Methods: The 9-item NIH-CPSI was translated into Spanish according to a standard methodology of 2 forward translations, 1 reconciled version, back translation of the reconciled version and 3 independent reviews by bilingual experts. The purpose of this methodology was to create a single universal Spanish version that would be acceptable to native Spanish speakers inside and outside of the United States. After the translation process the Spanish version was pre-tested in Argentina, Mexico, Spain and the United States. Patient responses were analyzed to identify necessary modifications. The internal consistency of the CPSI was evaluated using Cronbach's alpha. Pearson's product moment correlations were used to evaluate construct validity.Results: Data were collected from chronic prostatitis patients, including 15 in Argentina, 15 in Mexico, 4 in the United States and 3 in Spain. The translation had high reliability overall and in all subscales (Cronbach's coefficient alpha = 0.81 to 0.94), and the subscales correlated well with each other (r = 0.76 to 0.97). However, patients expressed difficulty in distinguishing the response categories "a menudo" ("often") from "normalmente" ("usually") in question 3. We revised "a menudo" to "muchas veces" ("much of the time") and "normalmente" to "casi siempre" ("almost always") to improve the distinctiveness of response categories.Conclusions: The Spanish NIH-CPSI has high reliability as well as face and construct validity in Spanish speaking men from various countries. The Spanish NIH-CPSI permits cross-cultural comparisons of men with chronic nonbacterial prostatitis.
