Sodium restriction is a non-pharmacological measure often recommended to patients with heart failure (HF). However, adherence is low, being among the most common causes of HF decompensation. The Dietary Sodium Restriction Questionnaire (DSRQ) aims at identifying factors that affect adherence to dietary sodium restriction by patients with HF. In Brazil, there are no instruments to assess these factors.
Perform the transcultural adaptation of DSRQ.
Methodological study that involved the following steps: translation, synthesis, back-translation, review by an expert committee, pretest of the final version and analysis of interobserver agreement. In the pretest, items and their understanding were evaluated, as well as internal consistency by Cronbach's alpha. The instrument was simultaneously and independently administered by two researchers and the kappa test was used for agreement analysis.
Only one question underwent major semantic and/or cultural alteration. At the pretest, Cronbach's alpha for the total obtained was 0.77; for the Attitude, Subjective Norm and Behavioral Control scales were obtained, respectively: 0.66, 0.50 and 0.85. At the agreement step, the Kappa was calculated for 12 of the 16 questions, with values ranging from 0.62 to 1.00. In items for which the calculation was not possible, the incidence of equal responses ranged from 95% to 97.5%.
Based on the transcultural adaptation of DSRQ, it was possible to propose a version of the questionnaire for further evaluation of psychometric properties.
钠限制是心力衰竭（HF）患者常被推荐的非药物治疗措施。然而，其依从性较低，是 HF 失代偿最常见的原因之一。膳食钠限制问卷（DSRQ）旨在确定影响 HF 患者对膳食钠限制依从性的因素。在巴西，没有评估这些因素的工具。
对 DSRQ 进行跨文化调适。
这是一项方法学研究，包括以下步骤：翻译、综合、回译、专家委员会审查、预测试最终版本以及观察者间一致性分析。在预测试中，评估了项目及其理解，以及 Cronbach's alpha 进行的内部一致性分析。该工具由两名研究人员同时独立进行管理，并使用kappa 检验进行一致性分析。
只有一个问题经历了重大的语义和/或文化改变。在预测试中，总分为 0.77；态度、主观规范和行为控制量表的 Cronbach's alpha 分别为 0.66、0.50 和 0.85。在一致性步骤中，对 16 个问题中的 12 个进行了 Kappa 计算，值范围为 0.62 至 1.00。在无法进行计算的项目中，同等反应的发生率从 95%到 97.5%不等。
基于 DSRQ 的跨文化调适，我们可以提出一个问卷版本，以便进一步评估其心理测量特性。
