OBJECTIVE
To investigate the evidence of content validity and reliability of the Brazilian version of the Nutritional Literacy Scale (NLS) after the cultural adaptation process.
METHODS
Psychometric study of 1,197 users of the National Health Service (Brazilian SUS). The NLS was culturally adapted to Brazilian Portuguese and six items of the original scale were modified to improve its understanding, giving rise to the Brazilian version of the scale named NLS-BR. The analysis of evidence of content validity of the NLS-BR was performed using the Item Response Theory (IRT).
RESULTS
The final version of the NLS-BR had 23 items and proved to be adequate to assess nutritional literacy in adults assisted by the Brazilian SUS.
FINAL CONSIDERATIONS
The NLS-BR proved to be of adequate understanding and demonstrated evidence of content validity and reliability for users of the Brazilian SUS.
目的
在文化适应过程后，研究巴西版营养素养量表（NLS）的内容效度和信度的证据。
方法
对 1197 名国家卫生服务（巴西 SUS）用户进行心理测量学研究。NLS 被文化适应为巴西葡萄牙语，原始量表的六个项目进行了修改，以提高其理解程度，从而产生了名为 NLS-BR 的巴西版本量表。使用项目反应理论（IRT）对 NLS-BR 的内容效度证据进行了分析。
结果
NLS-BR 的最终版本有 23 个项目，证明在巴西 SUS 协助下评估成年人的营养素养是足够的。
最终考虑
NLS-BR 被证明具有足够的理解能力，并为巴西 SUS 的用户提供了内容效度和信度的证据。
