[Study of the sensitivity of the Longitudinal Bond Evaluative Matrix in (MAVIL) in Primary Health Care].

Sensitivity studies are used to evaluate measuring instruments and assess their ability to capture differences in measurements taken from the same object at different times or from different objects at the same time. The Longitudinal Bond Evaluative Matrix (MAVIL) is a method for evaluating care in Primary Health Care. It is based on the concept of longitudinal bond, consisting of three dimensions: recognition of the team as a regular source of care, interpersonal relationship between professional and patient, and continuity of information, from which the indicators are derived. The objective was to study the degree of the sensitivity of the MAVIL method. A descriptive analysis of the data and a hypothesis test of equality of sample means were performed when applying the MAVIL in two UBS in Dourados. These results were compared with the results of a previous application in two UBS in Rio de Janeiro. For Dimension 1, three of the four UBS had equivalent results. For dimension 2, the UBS in Rio de Janeiro presented similar values, and in Dourados, significant differences. For Dimension 3, the performance was low in both locations. The results indicated MAVIL's ability to identify differences in the degree of bond between UBS.
