This study aimed to translate, cross-culturally adapt, and validate the Heart Disease Fact Questionnaire into Brazilian Portuguese.
The Brazilian version of the Heart Disease Fact Questionnaire was developed through the processes of translation, back-translation, review committee, and pre-test. Test-retest reliability was measured using the intraclass correlation coefficient and the kappa coefficient. Internal consistency was measured using Cronbach's alpha. For construct validity, the total Heart Disease Fact Questionnaire score was correlated with the Diabetes Knowledge Scale and the Diabetes Attitudes Questionnaire. Ceiling and floor effects were also evaluated in this study.
For construct validity and floor and ceiling effect measurements, a total of 100 participants were selected. Reliability was measured using a sub-sample of 30 participants from the total sample. We identified adequate values of reliability (kappa between 0.22 and 1.00 and ICC=0.75) and internal consistency (Cronbach's alpha=0.79). We observed adequate correlations of the Heart Disease Fact Questionnaire score with Diabetes Knowledge Scale (r=0.348) and Diabetes Attitudes Questionnaire (r=0.136). No ceiling or floor effects found.
Brazilian Portuguese version of the Heart Disease Fact Questionnaire has adequate psychometric properties according to the best scientific recommendations.
本研究旨在将心脏病知识问卷翻译成巴西葡萄牙语，并对其进行跨文化适应性验证。
通过翻译、回译、审查委员会和预测试等过程，形成了巴西葡萄牙语版的心脏病知识问卷。使用组内相关系数和 Kappa 系数来测量测试-重测信度。使用 Cronbach's alpha 来测量内部一致性。为了进行结构有效性验证，将心脏病知识问卷的总分与糖尿病知识量表和糖尿病态度问卷相关联。本研究还评估了天花板和地板效应。
在结构有效性和天花板和地板效应测量中，共选择了 100 名参与者。使用总样本中的 30 名参与者的子样本来测量可靠性。我们发现可靠性（Kappa 值在 0.22 到 1.00 之间，ICC=0.75）和内部一致性（Cronbach's alpha=0.79）都有足够的值。我们观察到心脏病知识问卷的分数与糖尿病知识量表（r=0.348）和糖尿病态度问卷（r=0.136）有足够的相关性。没有发现天花板或地板效应。
根据最佳科学建议，巴西葡萄牙语版的心脏病知识问卷具有足够的心理测量学特性。
