Objective
Translate, adapt and validate the Appraisal of Self-care Agency Scale-Revised (ASAS-R) for Brazil.
Methods
A descriptive method for adapting measurement instruments was used with 150 diabetes mellitus patients. The instrument underwent translation, synthesis of independent translations, evaluation by a committee of judges, back-translation and submittal of back-translation to original authors, semantic validation, submittal of the adapted version to original authors, and pretesting.
Results
The ASAS-R maintained semantic, cultural and conceptual equivalence. Cronbach’s alpha was 0.74; the intraclass correlation coefficient for test-retest reliability was 0.81; and interobserver agreement was 0.84.
Conclusion
The Brazilian-Portuguese version maintained conceptual, semantic and cultural validity, as compared to the original version. In the discriminant validity, there was correlation between capacity for self-care, depression and perceived health, but not social support. There were significant differences between groups regarding age, education levels and insulin self-application.
