Validation of the Brazilian Version of the Modified Scale for Delineating Advanced Practice Nursing Roles

Abstract

Objectives: to validate the Brazilian version of the Modified Scale for Delineating Advanced Practice Nursing Roles. Methods: this was a methodological study for the clinical validation of an instrument, conducted with 207 nurses working in primary care. Exploratory and confirmatory factor analysis, Cronbach’s alpha test, and z-test for proportion comparison were used. Results: the internal reliability of the scale was 0.944, with alpha greater than 0.80 in most domains, except for Education (0.786). In the exploratory factor analysis, considering the criterion of eigenvalue greater than one, eight factors were identified, explaining 79.38% of the variance. In the comparison of proportions, the adequate responses (≥ 2) in the domain of Comprehensive Direct Care, in both analyzed groups, were statistically equal. This domain had the highest score of adequate responses, followed by Education and Systems Support. Insufficient scoring was observed in the domains of Publication and Professional Leadership. Conclusions: the instrument demonstrated stability and reliability to be used in the evaluation of advanced nursing practice.
