About the Validation of this Measure
Country where validated:
Brazil
Content validity:
The development of the tool included cultural adaptation of the original NVS, and translation of the tool by two bilingual experts in public health. The back-translation from version 2 to English was done by an English-literate translator, who was unaware of the research objectives and did not take part in any of the previous steps. The final version was pre-tested in a pilot study.
Reliability (Cronbach Alpha):
0.75
Reliability notes:
Cronbach’s α presented values of 0·75 for GP and of 0·74 for HE.
