Researchers lack a properly validated instrument to measure perceptions of chronic disease in Arabic language contexts. This study aimed to adapt and validate the Revised-Illness Perception Questionnaire (IPQ-R) for Arabic speaking chronic illness patients.
A cross-sectional design was conducted to examine the psychometric properties of the adapted English version of the IPQ-R for Arabic speaking chronic illness patients. The study instrument was an Arabic version of the IPQ-R prepared through a translation process. The reliability and validity of the instrument were assessed using exploratory and confirmatory factor analysis and Cronbach's alpha coefficient. Three hundred and sixteen participants (ages 16-79) from the Batna region in Algeria completed the IPQ-R.
A total of 316 (100%) patients responded to this study. Regarding internal consistency, Cronbach's alpha a coefficient was consistently higher than 0.45. Several areas of fit were identified and substantial changes to the measurement model were made, such as the deletion of 22 items from the original 38-item IPQ-R and two items from the original 18 causal items this accounted for 64.63% of the total variance, and the respecification of indicators had to be applied to achieve acceptable model fit. The final model consists of two sections: The 16-item Arabic IPQ-R, which had a good fit; (CMIN/Df = 1.30, < 0.001, CFI = 0.93, RMSEA = 0.08, SRMR = 0.03), and was similar to the Arabic 16 causal items (CMIN/DF = 1.11, < 0.001, CFI = 0.95, RMSEA = 0.080, SRMR = 0.02).
The factor structure concurred with prior finding despite differences to the type of sample and cultural considerations that might explain these findings. Replication of this study in Algerian patients with specific illness, such as silicosis, breast cancer and multiple sclerosis. Further psychometric testing on other large samples is recommended.
在阿拉伯语环境中，研究人员缺乏一种经过适当验证的工具来衡量对慢性病的认知。本研究旨在为讲阿拉伯语的慢性病患者改编并验证修订后的疾病认知问卷（IPQ-R）。
采用横断面设计来检验改编后的IPQ-R英文版对讲阿拉伯语的慢性病患者的心理测量特性。研究工具是通过翻译过程准备的IPQ-R阿拉伯语版本。使用探索性和验证性因素分析以及克朗巴赫α系数评估该工具的信度和效度。来自阿尔及利亚巴特纳地区的316名参与者（年龄在16 - 79岁之间）完成了IPQ-R。
共有316名（100%）患者对本研究做出回应。关于内部一致性，克朗巴赫α系数始终高于0.45。确定了几个拟合区域，并对测量模型进行了重大修改，例如从最初的38项IPQ-R中删除了22项，从最初的18项因果项目中删除了2项，这占总方差的64.63%，并且必须应用指标的重新设定以实现可接受的模型拟合。最终模型由两部分组成：16项阿拉伯语IPQ-R，拟合良好；（CMIN/Df = 1.30，< 0.001，CFI = 0.93，RMSEA = 0.08，SRMR = 0.03），并且与16项阿拉伯语因果项目相似（CMIN/DF = 1.11，< 0.001，CFI = 0.95，RMSEA = 0.080，SRMR = 0.02）。
尽管样本类型和文化因素存在差异，可能解释了这些发现，但因素结构与先前的研究结果一致。建议在阿尔及利亚患有特定疾病（如矽肺病、乳腺癌和多发性硬化症）的患者中重复进行这项研究。建议对其他大样本进行进一步的心理测量测试。
