To translate into Arabic and validate the SF-36 quality of life index in a Tunisian Arabic population.
No validated Arabic quality of life index is published.
Arabic translation of the SF-36 scale was obtained by the "forward/backward translation" method. Adaptations were made after a pilot study involving 22 subjects from general population. Inter-rater reliability was assessed by use of intraclass correlation coefficient (ICC) and Bland and Altman method. Construct validity was assessed by Spearman rank correlation coefficient (convergent and divergent validity), and factor analysis with Varimax rotation. Internal consistency was assessed by Cronbach alpha coefficient.
We note that 130 Tunisian subjects were included in the validation study. No items were excluded. Inter-rater reliability was excellent (ICC=0.98). Cronbach alpha coefficient was 0.94 conferring to translated index a good internal consistency. Expected divergent and convergent validity results suggested good construct validity. Two main factors were extracted by factor analysis and explained 62.3% of the cumulative variance: the first factor represented mental component, the second physical component. The Cronbach alpha coefficient was 0.88 and 0.91 respectively for factor 1 and factor 2.
We translated into Arabic language and adapted the SF-36 scale for use in Tunisian population. The Arabic version is reliable and valid. Although the scale was validated in a Tunisian population, we expect that it is suitable for other Arab populations, especially North Africans. Further studies are needed to confirm such a hypothesis.
将 SF-36 生活质量指数翻译成阿拉伯语，并在突尼斯阿拉伯人群中进行验证。
目前尚无经过验证的阿拉伯语生活质量指数。
SF-36 量表的阿拉伯语翻译通过“正向/反向翻译”法获得。在涉及 22 名普通人群受试者的试点研究后进行了调整。通过使用组内相关系数（ICC）和 Bland 和 Altman 方法评估了评分者间的可靠性。通过 Spearman 秩相关系数（收敛和发散有效性）和 Varimax 旋转的因子分析评估了结构有效性。通过 Cronbach α 系数评估了内部一致性。
我们注意到，有 130 名突尼斯受试者参加了验证研究。没有排除任何项目。评分者间的可靠性非常好（ICC=0.98）。Cronbach α 系数为 0.94，表明翻译后的指数具有良好的内部一致性。预期的发散和收敛有效性结果表明结构有效性良好。通过因子分析提取了两个主要因子，解释了累计方差的 62.3%：第一个因子代表心理成分，第二个因子代表身体成分。因子 1 和因子 2 的 Cronbach α 系数分别为 0.88 和 0.91。
我们将 SF-36 量表翻译成阿拉伯语并进行了调整，以适用于突尼斯人群。阿拉伯语版本可靠且有效。尽管该量表在突尼斯人群中进行了验证，但我们预计它适用于其他阿拉伯人群，特别是北非人群。需要进一步的研究来证实这一假设。
