Self-care is considered as the best method of blood pressure control. Because the prevalence of hypertension in Arab countries is high and continuously increasing through the years, more attention is needed to evaluate patients' self-care for hypertension, to enable further studies to develop the appropriate intervention. The Self-care of Hypertension Inventory (SC-HI) is a scale that has been developed to measure the maintenance, monitoring, and management of a person with hypertension.
The aim of this study was to assess the psychometric properties of the Arabic version of the SC-HI scale among older adults.
A cross-cultural adaptation process was used, where structural validity was assessed through factor analysis and interobserver agreement using Cohen κ. The reliability of internal consistency was determined through Cronbach's α and scale item correlation. Test-retest examined the interclass correlation and was tested by paired t test.
The mean age of our sample is 63 ± 7.8 years, and most were educated (illiterate patients, 14%). Some modification was done for the scale items. Item-level content validity index ranged between 0.85 and 1, and average scale-level content validity was 0.96. Interobserver adjustment showed high agreement. Cronbach's α was 0.89. Test-retest reliability showed no differences (t = -0.298, P = 0,767), and interclass correlation was 0.85 (95% confidence interval, 0.078-0.90; P < .01). Factor analysis extracted 2, 3, and 1 signal factors for maintenance, management, and confidence subscales, respectively.
The adapted Arabic version of SC-HI scale is shown to be valid and reliable among older adults. Further studies are need for further reliability analyses among large groups from various Arab countries.
自我护理被认为是控制血压的最佳方法。由于阿拉伯国家高血压患病率很高且多年来持续上升，因此需要更多关注来评估患者对高血压的自我护理情况，以便进一步研究制定适当的干预措施。高血压自我护理量表（SC-HI）是一种用于测量高血压患者维持、监测和管理情况的量表。
本研究旨在评估老年人群中SC-HI量表阿拉伯语版本的心理测量特性。
采用跨文化适应过程，通过因子分析评估结构效度，并使用Cohen κ评估观察者间一致性。通过Cronbach's α和量表项目相关性确定内部一致性的可靠性。重测检验组内相关性，并通过配对t检验进行测试。
我们样本的平均年龄为63±7.8岁，大多数人受过教育（文盲患者占14%）。对量表项目进行了一些修改。项目水平的内容效度指数在0.85至1之间，平均量表水平的内容效度为0.96。观察者间调整显示高度一致。Cronbach's α为0.89。重测信度无差异（t = -0.298，P = 0.767），组内相关性为0.85（95%置信区间，0.078 - 0.90；P <.01）。因子分析分别为维持、管理和信心子量表提取了2个、3个和1个主要因子。
改编后的SC-HI量表阿拉伯语版本在老年人中显示出有效性和可靠性。需要进一步研究对来自不同阿拉伯国家的大群体进行进一步的信度分析。
