SMAF
Functional Autonomy Measurement System (SMAF)
The SMAF is a clinical rating scale of functional autonomy, mainly used in geriatrics, rehabilitation and the organization of home support. Administered by a trained professional, it explores 29 functions divided into five domains: activities of daily living, mobility, communication, mental functions and household activities. The tool does not only measure disability; it also takes into account the human and material resources that partially or fully compensate for the observed difficulties. It helps objectively determine the level of dependence, monitor a patient's progress, structure referral decisions and plan the necessary assistance. For psychologists working with older adults or with people whose cognitive difficulties affect daily life, the SMAF provides a concrete functional perspective, useful in psychogeriatrics, neuropsychology and multidisciplinary assessments.

Scoring & interpretation
Each function is rated according to the person's actual performance, based on the interview, observation and, if needed, a practical task. Ratings range from 0 to -3: 0 independent, -0.5 independent with difficulty, -1 supervision or stimulation required, -2 partial help required, -3 total dependence. The total score ranges from 0 to -87. The more negative the score, the greater the loss of autonomy. Some settings use the absolute value, from 0 to 87, to express the functional burden. Subscores by domain can be calculated. Interpretation must always take into account the available compensatory resources and their stability. A change of about 5 points is generally considered clinically significant.
