Background

In Brazil, there are no instruments available to measure the presence, frequency, severity and distress related to heart failure (HF) symptoms.

Aims

To adapt the Symptom Status Questionnaire - HF (SSQ-HF) into Brazilian Portuguese and to examine the content validity of the adapted version.

Methods

The instrument was translated, back-translated and evaluated by an expert committee for semantic, idiomatic, cultural, and conceptual equivalences. An agreement ≥80% was considered adequate. The adapted version was evaluated by both an expert committee (n = 9) for clarity, theoretical relevance and practical relevance (acceptable content validity coefficient (CVC): ≥0.70), and by a patient committee regarding understanding (n = 40).

Results

The adapted version obtained 100% agreement regarding the equivalences. The total instrument CVC was 0.99. All patients understood the items.

Conclusion

The SSQ-HF-Brazilian version has satisfactory evidence of equivalence and content validity. Additional psychometric tests are deemed to confirm that the instrument can be used in Brazil.

症状状态问卷–心力衰竭–巴西文版：跨文化适应和内容验证

背景

在巴西，没有可用于测量与心力衰竭（HF）症状有关的存在，频率，严重性和困扰的仪器。

目的

将症状状态问卷-HF（SSQ-HF）改编为巴西葡萄牙语，并检查改编版本的内容有效性。

方法

对该工具进行了翻译，回译和由语义，惯用，文化和概念对等的专家委员会评估。协议≥80％被认为是足够的。改编版经过专家委员会（n  = 9）的清晰度，理论相关性和实际相关性（可接受的内容有效性系数（CVC）：≥0.70）以及患者委员会关于理解的评估（n  = 40）。

结果

改编版在等效性方面获得了100％的同意。仪器的总CVC为0.99。所有患者都了解这些项目。

结论

SSQ-HF-巴西版本具有令人满意的等效性和内容有效性证据。附加的心理测验被认为可以确认该仪器可在巴西使用。
