功能性自主测量系统（SMAF）是一种旨在评估与29种功能相关的残疾的工具，具有四点量表（从0：独立到-3：依赖）。对于流行病学研究，可以获得总分和五个分项分数。修订后的版本在许多项目中增加了-0.5级，以表示独立完成但有困难的活动。该研究的目的是验证SMAF总分和分项分数的重测和评分者间信度。在从家庭到长期护理医院的9个不同的居住环境中随机招募了90名受试者。一半的受试者由同一名护士在2周内进行评估（重测），另一半由两名不同的护士在相同的时间间隔内进行两次评估（评估者间）。结果显示，组内相关系数（ICC）为0.95和0.96的总成绩的重测和评分员间的信度，分别。两种类型可靠性的所有分项得分的ICC均超过0.74。评估者间可靠性的两个SMAF子评分存在小的系统偏倚。增加一个新的级别并没有改变该量表的可靠性。
The Functional Autonomy Measurement System (SMAF) is an instrument designed to assess disabilities related to 29 functions with a four-point scale (from 0: independent to -3: dependent). For epidemiological studies, a total score and five sub-scores can be obtained. A revised version was developed adding a -0.5 level to many items to indicate an activity accomplished independently but with difficulty. The objective of the study was to verify the test-retest and inter-rater reliability of the total score and sub-scores of the SMAF. Ninety subjects were randomly recruited in nine different residential settings ranging from home to long-term-care hospitals. Half of the subjects were assessed by the same nurse within a 2-week interval (test-retest) and the other half were assessed twice by two different nurses within the same interval (inter-rater). Results show intra-class correlation coefficients (ICC) of 0.95 and 0.96 for the total scores on test-retest and inter-rater reliability, respectively. The ICC were over 0.74 for all sub-scores for both types of reliability. A small systematic bias was present for two SMAF subscores on the inter-rater reliability. The addition of a new level did not modify the reliability of the scale.
