目标
目的：测量简易营养评估(MNA)在住院老人中的信度。
设计
12天观察者间可靠性研究。
参与者和背景
所有受试者在1996年期间在马塔罗(西班牙巴塞罗那)的两个长期老年病房住了4个月(n=67)。
测量
在每个中心，不同的训练有素的护士在两个不同的场合独立管理MNA。
结果
两次MNA的均分(标准差)分别为20.8分(5.4分)和21.3分(4.6分)。根据Cronbach‘s Alpha估计，第一次和第二次评估的内部一致性分别为0.83和0.74。根据组内相关系数(ICC)，MNA总分重测信度为0.89，连续条目重测信度高于0.89。根据Kappa指数，MNA分层总分测验的重测信度很高(0.78)；在MNA的18个序号或名义条目中，12个条目“几乎完美”或“基本”，5个条目“中等”至“一般”，I个条目“轻微”。Kappa指数最低的项目是主观健康评估、每天喝水的次数和臂围(前者的ICC=0.91)。
结论
根据其内部一致性和重测重复性，MNA测验具有良好的可靠性水平。通过对一些可靠性较低的项目的分类和内容进行细化，仍然可以进行一些改进。
OBJECTIVES
To measure the reliability of the Mini Nutritional Assessment (MNA) in institutionalized elderly people.
DESIGN
12 day interobserver reliability study.
PARTICIPANTS AND SETTING
All subjects admitted to two long term geriatric units in Mataró (Barcelona, Spain) over 4 months during 1996 (n=67).
MEASUREMENTS
in each center, different trained nurses independently administered the MNA on two separate occasions.
RESULTS
Mean (standard deviation) scores for the two assessments of the MNA were 20.8 (5.4) and 21.3 (4.6) respectively. Internal consistency, estimated by the Cronbach's Alpha, were 0.83 and 0.74 for the first and second assessment respectively. Test-retest reliability, according to the intraclass correlation coefficient (ICC), was 0.89 for the total MNA score and higher than 0.89 for its continuous items. According to the Kappa index, test-retest reliability for the stratified total MNA was substantial (0.78); for the 18 ordinal or nominal items of the MNA it was 'almost perfect' or 'substantial' in 12 items, 5 were 'moderate' to 'fair' and in I item it was 'slight'. Subjective health evaluation, the number of glasses of liquids per day, and brachial circumference (this former with an ICC=0.91) were the items with the lowest Kappa indices.
CONCLUSION
The MNA test has good levels of reliability, according to its internal consistency and its test-retest reproducibility. Some improvements can still be introduced by refining the categorization and content of some items with low reliability.
