Validation of the knowledge breastfeeding scale into brazilian portuguese

Abstract

Objective

To translate and validate the Knowledge Breastfeeding Scale into Brazilian Portuguese.

Methods

A methodological study of tool validation carried out in six steps: translation, back-translation, judges committee analysis, pretest, review of scores and assessment of psychometric properties. The validation process was performed with 65 postpartum women, in a joint hospital accommodation unit and in the follow-up in a primary care unit, in Western Paraná, between March and July 2018, with descriptive statistical data analysis.

Results

In the assessment of psychometric properties in the pretest, a Cronbach’s alpha of 0.78 was obtained and in the test-retest of 0.61. The intra-class correlation between test and retest was 0.756. The tool presented satisfactory internal consistency and perfect agreement.

Conclusion

The translated version of the scale proved to be valid and viable and its use in future research will allow to complement the psychometric analyzes.
