This is the first study to assess the psychometric properties of the Y-SF-12. It appears to be valid and may be an appropriate tool for assessing health-related quality of life among Yoruba population. The tool may help to improve the health outcomes of individuals, and redress health inequalities in low and middle-income countries.
Short Form 12 (SF-12) health survey has found its utility in clinical and research settings because of its short length that spares time. Though several translations into other languages do exist there is none available in Yoruba language. Hence, this study's objective was to culturally adapt and determine the reliability and validity of the Yoruba translated version of the SF-12.
Forward and backward translations of SF-12 into Yoruba version of SF-12 (Y-SF-12) were done using the International Quality of Life Assessment Project Guidelines. Healthy participants were assessed using both English and Yoruba versions of SF-12 for the validation phase, and two weeks later were reassessed with the Y-SF-12 for the reliability phase.
Participants were 225 males and 171 females. The mean scores for each scale range from 73.4 to 86.1, with no gender difference. All scale and domain scores evidenced a negative skew and ranges from -1.79 to -0.62. Concurrent validity (0.879 - 0.938) and convergent validity (0.786 - 0.907) appeared to be good as reflected by their correlation values. The internal consistency of Y-SF-12 was good as Cronbach's Alpha ranged between 0.899 and 0.968, while the Intraclass Correlation Coefficient (ICC) ranged between 0.775 and 0.949.
这是第一项评估 Y-SF-12 心理测量特性的研究。它似乎具有有效性，可能是评估约鲁巴人群健康相关生活质量的合适工具。该工具可能有助于改善个体的健康结果，并解决中低收入国家的健康不平等问题。
简短形式 12 项健康调查（SF-12）因其简短的长度而节省时间，因此在临床和研究环境中得到了广泛应用。虽然已经有几种翻译成其他语言的版本，但在约鲁巴语中没有。因此，本研究的目的是对 SF-12 进行文化适应性改编，并确定 SF-12 的约鲁巴语翻译版本的可靠性和有效性。
使用国际生活质量评估项目指南对 SF-12 进行正向和反向翻译，得到 SF-12 的约鲁巴语版本（Y-SF-12）。在验证阶段，使用 SF-12 的英语和约鲁巴语版本评估健康参与者，在可靠性阶段，两周后使用 Y-SF-12 对其进行重新评估。
参与者中有 225 名男性和 171 名女性。每个量表的平均得分范围从 73.4 到 86.1，性别之间没有差异。所有量表和域得分都有负偏态，范围从-1.79 到-0.62。反映在其相关值上，同时效度（0.879-0.938）和收敛效度（0.786-0.907）似乎很好。Y-SF-12 的内部一致性良好，Cronbach's Alpha 范围在 0.899 到 0.968 之间，而内类相关系数（ICC）范围在 0.775 到 0.949 之间。
