There is a lack of valid and specific tools to measure chronic constipation severity in Brazil.
To validate the Constipation Scoring System for Brazilian spoken Portuguese.
Translation, cultural adaptation, and validation itself (reliability and convergent and divergent validation). Translation: definitive version from the original version's translation and evaluation by specialists. Cultural adaptation: score content analysis of the definitive version, as an interview to patients. Interobserver reliability: application by two researchers on the same day. Intraobserver reliability: same researcher at different times, in a 7-day interval. Divergent validation: non-constipated volunteers. Convergent validation: two groups, good response to clinical treatment and refractory to treatment.
Cultural adaptation: 81 patients, 89% female, with mean age of 55 and seven years of schooling, and overall content validity index was 96.5%. Inter and intraobserver reliability analysis: 60 patients, 86.7% female, mean age of 56 and six years of schooling, and the respective intraclass correlation coefficients were 0.991 and 0.987, p<0.001. Divergent validation: 40 volunteers, 25 male, mean age of 49 years, and the mean global score was 2. Convergent validation of patients with good response to clinical treatment: 47 patients, 39 female, mean age of 60 and six years of schooling, and the pre- and post-treatment scores were 19 and 8, respectively (p<0.001). Convergent validation of refractory to clinical treatment patients: 75 patients, 70 female, mean age of 53 and seven years of schooling, and the global average score was 22.
The Constipation Scoring System (Índice de Gravidade da Constipação Intestinal) validated for the Brazilian population is a reliable instrument for measuring the severity of intestinal chronic constipation.
在巴西，缺乏有效且特定的工具来衡量慢性便秘的严重程度。
验证巴西葡萄牙语版便秘评分系统的有效性。
翻译、文化适应性调整和验证本身（可靠性以及收敛和发散验证）。翻译：从原始版本的翻译中得出最终版本，并由专家进行评估。文化适应性调整：对最终版本的评分内容进行分析，采用患者访谈的方式。观察者间可靠性：由两名研究人员在同一天进行应用。观察者内可靠性：同一名研究人员在不同时间，间隔 7 天进行。发散验证：非便秘志愿者。收敛验证：两组，对临床治疗有良好反应和对治疗有抵抗的患者。
文化适应性调整：81 例患者，89%为女性，平均年龄 55 岁，受教育年限为 7 年，总体内容效度指数为 96.5%。观察者间和观察者内可靠性分析：60 例患者，86.7%为女性，平均年龄 56 岁，受教育年限为 6 年，相应的组内相关系数分别为 0.991 和 0.987，p<0.001。发散验证：40 名志愿者，25 名男性，平均年龄 49 岁，全球平均得分为 2 分。对临床治疗有良好反应的患者的收敛验证：47 例患者，39 例为女性，平均年龄 60 岁，受教育年限为 6 年，治疗前后评分分别为 19 和 8，p<0.001。对临床治疗有抵抗的患者的收敛验证：75 例患者，70 例为女性，平均年龄 53 岁，受教育年限为 7 年，全球平均得分为 22 分。
为巴西人群验证的便秘评分系统（Índice de Gravidade da Constipação Intestinal）是一种可靠的工具，可用于衡量肠道慢性便秘的严重程度。
