To develop and validate a specific instrument to measure lifestyle of type 2 diabetes mellitus (DM2) patients.
A longitudinal, observational, prospective study was conducted between March 2001 and April 2002 at family medicine healthcare units of the Instituto Mexicano del Seguro Social (Mexican Institute of Social Security (MISS)) in Mexico State's East District. A self-administered instrument (instrument to measure diabetic lifestyles, IMEVID) was designed to measure the lifestyles of diabetic patients. It was submitted for review by a multidisciplinary group of experts who assessed its logical and content validity to measure the lifestyle in DM2 patients. The instrument was administered on two different days to 412 adult subjects with DM2. Some items were excluded on the basis of the frequency with which their answer choices were selected, as well as the item-total correlation, and the item's significant loads in several domains in factorial analysis.
The sample population consisted of 389 (94.7% response) subjects who completed the study. Intraclass correlation coefficients for logical and content validity were 0.91 and 0.95 respectively. After depuration of items, the instrument had 25 closed items grouped in 7 domains: nutrition, physical activity, tobacco consumption, alcohol consumption, information on diabetes, emotions, and therapeutic adherence. The global rating of the questionnaire had a Cronbach's alpha of 0.81 and a test-retest correlation coefficient of 0.84.
The specific questionnaire IMEVID is the first to measure the lifestyle in subjects with DM2. It has logical validity, content validity, and a good level of consistency.
开发并验证一种用于测量2型糖尿病（DM2）患者生活方式的特定工具。
2001年3月至2002年4月期间，在墨西哥州东区墨西哥社会保障局（Mexican Institute of Social Security，MISS）的家庭医学保健单位进行了一项纵向、观察性、前瞻性研究。设计了一种自我管理工具（测量糖尿病生活方式的工具，IMEVID）来测量糖尿病患者的生活方式。该工具提交给了一个多学科专家小组进行审查，他们评估了该工具在测量DM2患者生活方式方面的逻辑和内容效度。该工具在两个不同的日子对412名成年DM2患者进行了施测。根据答案选项的选择频率、项目与总分的相关性以及项目在因子分析中在几个领域的显著载荷，排除了一些项目。
样本人群包括389名（94.7%的应答率）完成研究的受试者。逻辑效度和内容效度的组内相关系数分别为0.91和0.95。经过项目净化后，该工具包含25个封闭式项目，分为7个领域：营养、身体活动、烟草消费、酒精消费、糖尿病信息、情绪和治疗依从性。问卷的总体评分的Cronbach's alpha为0.81，重测相关系数为0.84。
特定问卷IMEVID是首个用于测量DM2患者生活方式的工具。它具有逻辑效度、内容效度和良好的一致性水平。
