Background Knowledgeable people are more likely to follow their treatment plan and reduce hypertension morbidity and mortality. This study aimed to construct the validity and reliability of the Arabic version of the Hypertension Knowledge-Level Scale (HK-LS) among Saudis. Methods This cross-sectional questionnaire research targets hypertensives and non-hypertensives. Cronbach's alpha and Spearman's correlation matrix analysis measured the questionnaire's construct validity. Wilcoxon rank sum tests examined HK-LS tools' discriminant validity. A p<0.05 was considered significant. Results A total of 1424 responses were received. However, the 1419 individuals were evaluated after applying exclusion criteria. About 60% of the participants were female, with the most common age groups being 18-29 years (38.5%) and 40-49 years (24.0%). A personal history of hypertension was reported by 26.1%, and a family history of hypertension by 73.3% of the subjects. Cronbach's alpha for the whole HK-LS was 0.883, suggesting that the tool was reliable. All the items of the HK-LS questionnaire were significantly correlated with each other, except for a non-significant correlation between statements two and seven (r=0.05, p=0.091). The strongest correlations were apparent between items 19 and 20 (r=0.70, p<0.0001), items one and two (r=0.64, p<0.0001), and items 18 and 19 (r=0.56, p<0.0001). However, the weakest associations were reported among items two and six (r=0.06, p<0.05), items two and nine (r=0.07, p<0.05), and items one and 19 (r=0.07, p<0.05). The discriminant validity showed that a personal history of hypertension was associated with significantly higher scores of two HK-LS subscales, including definitions and complications. In addition, the overall knowledge score was significantly higher among participants with a positive history of hypertension among family and/or friends. Conclusions The Arabic version of the HK-LS was found to be a reliable and valid tool for measuring knowledge about hypertension among the Saudi population. This reliable instrument can assist medical professionals in establishing education programs.
知识渊博的人更有可能遵循治疗方案，从而降低高血压的发病率和死亡率。本研究旨在构建沙特人群中阿拉伯语版高血压知识水平量表（HK-LS）的效度和信度。
这项横断面问卷调查研究的对象是高血压患者和非高血压患者。采用Cronbach's α系数和Spearman相关矩阵分析来测量问卷的结构效度。采用Wilcoxon秩和检验来检验HK-LS工具的区分效度。p<0.05被认为具有统计学意义。
共收到1424份回复。然而，在应用排除标准后，对1419名个体进行了评估。约60%的参与者为女性，最常见的年龄组为18-29岁（38.5%）和40-49岁（24.0%）。26.1%的受试者报告有高血压个人史，73.3%的受试者报告有高血压家族史。整个HK-LS的Cronbach's α系数为0.883，表明该工具具有可靠性。HK-LS问卷的所有项目之间均显著相关，但陈述二和陈述七之间的相关性不显著（r=0.05，p=0.091）。最强的相关性出现在项目19和20之间（r=0.70，p<0.0001）、项目一和项目二之间（r=0.64，p<0.0001）以及项目18和项目19之间（r=0.56，p<0.0001）。然而，最弱的关联出现在项目二和项目六之间（r=0.06，p<0.05）、项目二和项目九之间（r=0.07，p<0.05）以及项目一和项目19之间（r=0.07，p<0.05）。区分效度表明，高血压个人史与HK-LS两个子量表（包括定义和并发症）的得分显著较高相关。此外，在有高血压家族史和/或朋友高血压病史阳性的参与者中，总体知识得分显著更高。
发现阿拉伯语版的HK-LS是一种可靠且有效的工具，可用于测量沙特人群中关于高血压的知识。这种可靠的工具可以帮助医学专业人员制定教育计划。
