Abstract

OBJECTIVE

This study aimed to perform the cross-cultural adaptation and validation of the NVS for Brazilian Portuguese.

MATERIAL AND METHODS

Two hundred and fifty adults responded to the adapted version of the NVS, the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30), ten questions of the National Functional Literacy Index (NFLI), and a questionnaire about demographic and oral health-related aspects. Statistical analysis determined the internal consistency, stability, difficulty of items, and convergent/discriminant/predictive validities of the NVS. p < .05 was considered significant.

RESULTS

The NVS displayed a good internal consistency (Cronbach's alpha = 0.79) and a fair stability (ICC = 0.57; 0.39-0.70 95% CI). Seventy-two percent of participants answered the easier question (#5) correctly, whereas only 28.4% were successful in responding the most difficult question (#1). The convergent validity of the NVS was demonstrated by its significant correlation with the BREALD-30 (Rs = 0.601, p < .001) and NFLI (Rs = 0.544, p < .001). The observation of higher NVS scores among health professionals, white and more educated people confirmed the discriminant validity of the instrument. Moreover, health literacy was a significant predictor of self-reported oral health and reason for dental utilization.

CONCLUSION

The NVS demonstrated adequate psychometric properties to be applied in Brazilian oral health epidemiological surveys.

摘要

目的

本研究旨在对葡萄牙语巴西版的成人健康素养简短问卷（NVS）进行跨文化调适及验证。

材料与方法

250名成年人对NVS的调适版本、巴西版牙科成人识字率快速评估（BREALD - 30）、国家功能素养指数（NFLI）的10个问题以及一份关于人口统计学和口腔健康相关方面的问卷进行了回答。统计分析确定了NVS的内部一致性、稳定性、项目难度以及聚合效度/区分效度/预测效度。p < 0.05被视为具有统计学意义。

结果

NVS显示出良好的内部一致性（克朗巴哈系数α = 0.79）和尚可的稳定性（组内相关系数ICC = 0.57；95%置信区间为0.39 - 0.70）。72%的参与者正确回答了较简单的问题（第5题），而只有28.4%的人成功回答了最难的问题（第1题）。NVS与BREALD - 30（斯皮尔曼相关系数Rs = 0.601，p < 0.001）和NFLI（Rs = 0.544，p < 0.001）的显著相关性证明了其聚合效度。在健康专业人员、白人和受教育程度较高的人群中观察到较高的NVS得分，证实了该工具的区分效度。此外，健康素养是自我报告的口腔健康和看牙原因的重要预测因素。
