Abstract
Abstract Objective: The objective of the study was to carry out the factorial validation of the questionnaire for the evaluation of informal social support (ASI) for the elderly. Method: It is a descriptive, observational, quantitative type research. It was executed between August and December of 2016 in the municipality of Natal, Rio Grande do Norte and other locations in Brazil. In Inclusion criteria, were have age 60 or older and cognitive ability preserved. We performed Exploratory Factor Analysis (AFE). As criterion of exclusion of the items was adopted a reference value greater than or equal to 0.35 of factorial load and greater or equal to 0.5 of commonality per item. To determine the amount of retained factors, the criteria of own values>1, minimum cumulative explained variance of 60% and parallel Horn analysis were observed. Results: A sample of 259 elderly people from the five regions of Brazil was obtained. After AFE, 4 items were excluded due to the poverty of their factorial loads, remaining 20 items in 4 retained factors. Conclusion: The instrument has good psychometric properties, such as acceptable factor loads and excellent commonalities.

Population aging is a global reality and this demographic and epidemiological change is occurring in Brazil in an accelerated form
Regarding the aforementioned validation process, in 2014 the American Educational Research Association (AERA), the American Psychological Association (APA), and the National Council on Measurement in Education (NCME)[19] proposed the development of instruments which included, among other steps, evidence of validity based on content, the response process and internal structure
The present study contemplated the factorial validity stage, based on Exploratory Factor Analysis, focusing on the previous steps in the construction of the instrument, among them, the proposition of items based on a literature review described in a manuscript published by Guedes et al.[17], validity based on content and on the response process, debated in the first section of this collectanea[26]
Summary
Population aging is a global reality and this demographic and epidemiological change is occurring in Brazil in an accelerated form. Studies describe how inadequate social conditions are directly associated with indicators of illness or adverse life conditions, and influence the individual’s emotional well-being[7,8,9,10,11,12]. From this perspective, Social Support (SS), especially informal support, plays an important role as a tool to support the health care of people aged 60 years or older[13,14]
