Validação psicométrica da versão brasileira do Geriatric Institutional Assessment Profile

Abstract

Objective: To evaluate the psychometric properties of the Geriatric Institutional Assessment Profile instrument in a sample of Brazilian nurses working in hospitals. Methods: Methodological and cross-sectional study, carried out with a sample of 301 nurses who worked in the care of patients in five hospitals, located in the states of Piaui and Minas Gerais. Exploratory factor analysis was used with the extraction of factors by the mean components’ method. Then, the Varimax rotation was applied. The following correlated constructs were evaluated: geriatric knowledge (Geriatric Nursing Knowledge/Attitudes scale); one that involves institutional barriers and facilitators of best practices (Geriatric Care Environment scale) and another one that emphasizes the interpersonal relationship and coordinating aspects of professional practice (Professional Issues subscales). Results: Exploratory factor analysis indicated that in the Brazilian version of the Geriatric Nursing Knowledge/Attitudes scale, a total of 30 items had adequate factor loadings (>=0.40) and defined six factors. The total explained variance was 40.5%. In the Geriatric Care Environment scale, 28 items were adequate and defined five factors. The total explained variance was 59.27%. In the Professional Issues subscales, 45 items were adequate and defined six factors. The total explained variance was 57.78%. Conclusion: The Brazilian version of the Geriatric Institutional Assessment Profile is valid and reliable and can be applied to assess perceptions, attitudes and knowledge about the most common geriatric disorders and identify barriers faced by nurses in the development of quality care.
