Family vulnerability index to disability and dependence (FVI-DD), by social and health conditions.

The Family Vulnerability Index to Disability and Dependence (FVI-DD) aims to summarize the dimensions of vulnerability to disability and dependence using family data monitored by Family Health Strategy (ESF) teams. This study aims to analyze the FVI-DD according to the social and health vulnerability, to validate and extract a cutoff point for each dimension. The FVI-DD was built with a sample of 248 families living in a region of São Paulo. The dimension related to health conditions was validated with good internal consistency, with respect to the Katz Index and the Lawton Scale, whereas the dimension related to social conditions was only validated in relation to Lawton Scale. Thus, a vulnerable family was defined as one with 15 or more points in the Total FVI-DD, and a vulnerable family in health conditions that with a score of 6 or more points in that dimension. Therefore, it is possible to classify families as not vulnerable, vulnerable in the social aspects, vulnerable in the health aspects and the more vulnerable family (social and health) using social indicators of empowerment and wear and health indicators related not only to the biological sphere, but also in the access to health services, health self-assessment and existing vulnerable groups.
