Abstract：
BACKGROUND: Inflammatory bowel disease comprises two conditions: ulcerative colitis and Crohn\'s disease. Inflammatory Bowel Disease Questionnaire 32 (IBDQ-32) is a specific questionnaire which has been translated from English into Spanish and validated. In the Spanish-speaking countries of America it has not been validated. The aim was to determine the psychometric properties, validity and reliability of the Mexican version of the IBDQ-32 questionnaire.
METHODS: A total of 316 patients with inflammatory bowel disease and 100 healthy controls participated in the study. The questionnaires IBDQ-32 and SF-36 were issued on two occasions (separated by 15 days). The psychometric properties of the Mexican version of the IBDQ-32 questionnaire were determined.
RESULTS: Patients with inflammatory bowel disease had an impaired quality of life compared to healthy controls. There were no differences between ulcerative colitis and Crohn\'s disease in the total scores of IBDQ-32 and its domains. The internal consistency reliability was good. The intraclass coefficient showed good reliability (repeated measurement) for total scale and all four subscales. Factor analysis explained variance is higher than 50% therefore is considered adequate/acceptable. The correlation between IBDQ-32 and SF-36 showed a satisfactory association. The social domain is the only one that presented a ceiling effect.
CONCLUSIONS: The Mexican version of the IBDQ-32 quality of life questionnaire is valid and reliable. This sample included the entire spectrum of inflammatory disease (remission and activity) and was comparable when assessing quality of life with the SF-36 generic questionnaire.

摘要：
背景：炎症性肠病包括两种疾病：溃疡性结肠炎和克罗恩病。炎症性肠病问卷32（IBDQ-32）是一种特殊的问卷，已从英语翻译为西班牙语并经过验证。在美国的西班牙语国家，它尚未得到验证。目的是确定心理测量特性，墨西哥版IBDQ-32问卷的效度和信度。
方法：共有316名炎症性肠病患者和100名健康对照者参与了这项研究。问卷IBDQ-32和SF-36分两次发放(间隔15天)。确定了墨西哥版IBDQ-32问卷的心理测量特性。
结果：与健康对照组相比，炎症性肠病患者的生活质量受损。溃疡性结肠炎和克罗恩病在IBDQ-32及其领域的总分上没有差异。内部一致性可靠性良好。对于总量表和所有四个子量表，组内系数显示出良好的可靠性（重复测量）。因子分析解释方差高于50%，因此被认为是足够的/可接受的。IBDQ-32和SF-36之间的相关性显示出令人满意的相关性。社会领域是唯一呈现天花板效应的领域。
结论：墨西哥版的IBDQ-32生活质量问卷是有效和可靠的。该样本包括炎性疾病的整个范围（缓解和活动），并且在使用SF-36通用问卷评估生活质量时具有可比性。
