measuring quality of life requires an instrument validated in the population language. The purpose of our study was to translate and analyze the psychometric properties of the literary Arabic version of the "diabetes health profile (DHP)-18".
we conducted a methodological study for psychometric evaluation and validation of the DHP-18, following the steps of the cross-cultural validation described by Vallerand. A convenience sample of people with diabetes was collected for this purpose. The developed questionnaire included participants' demographic characteristics, diabetes data and the experimental version of the DHP-18 questionnaire. Validity, reliability and questionnaire standards establishment were carried out.
a sample of 333 diabetics was recruited. Test-retest correlation coefficient (r = 0.985; p<0.01) and Cronbach's alpha coefficient (alpha = 0.840) showed that the experimental version was accurate in terms of temporal stability and internal consistency. The content validity index was 0.84 and showed that the questionnaire statements accurately measured the concepts under study. The exploratory principal axis factoring, using the orthogonal varimax rotation, allowed the extraction of a factorial solution with four independent factors, grouping the 18 items of the questionnaire. Correlation coefficients between the three corresponding dimensions of the theoretical model of the questionnaire were low and positive, between 0.431 and 0.535, confirming that each dimension measured a unique content.
the literary Arabic version of the DHP-18 has proven to be valid, reliable and ready for use in clinical practice in Tunisian people with diabetes.
生活质量的衡量需要一种在当地语言中经过验证的工具。我们的研究目的是翻译并分析阿拉伯语文学版的“糖尿病健康状况简表（DHP-18）”的心理测量特性。
我们按照 Vallerand 描述的跨文化验证步骤进行了 DHP-18 的心理测量评估和验证的方法学研究。为此目的收集了糖尿病患者的方便样本。开发的问卷包括参与者的人口统计学特征、糖尿病数据和实验版 DHP-18 问卷。进行了有效性、可靠性和问卷标准制定。
共招募了 333 名糖尿病患者。实验版的重测相关系数（r=0.985；p<0.01）和 Cronbach 的 alpha 系数（alpha=0.840）表明，在时间稳定性和内部一致性方面，实验版非常准确。内容效度指数为 0.84，表明问卷的陈述准确地衡量了研究中的概念。使用正交方差极大旋转的探索性主成分因子分析允许提取一个具有四个独立因子的因子解决方案，将问卷的 18 个项目分组。问卷理论模型的三个相应维度之间的相关系数较低且为正，介于 0.431 和 0.535 之间，证实了每个维度都测量了独特的内容。
阿拉伯语文学版的 DHP-18 已被证明在突尼斯的糖尿病患者中具有有效性、可靠性和可用于临床实践。
