Recent changes in nutrition trends may lead to health issues. In particular, the unhealthy eating habits of young adults suggest that future generations may be at risk. Therefore, the importance and necessity of nutrition literacy is becoming increasingly apparent.
The purpose of this study was to create a Turkish version of a short nutrition literacy (S-NutLit-Tr) scale for young adults developed by Vrinten et al (2023).
This research involved 115 young adults from Istanbul Gelişim University, who were selected through convenience sampling, a non-probability sampling method. After the original S-NutLit scale was translated into Turkish, the validity and reliability of the determined factor structure were tested on 115 young adults. Internal consistency was examined with the Cronbach Alpha coefficient. Confirmatory factor analysis was employed to validate the two sub-scale structures. Finally, measurement invariance was tested concerning participants' gender, aiming to ascertain whether the scale captured equivalent characteristics across different groups.
As a result of the reliability analysis conducted with the scale of S-NutLit-Tr, the Cronbach Alpha coefficient was obtained as 0.86 for the scale of S-NutLit-Tr. Additionally, it was found to be 0.84 and 0.77 for the "information skills" and "expert skills" sub-scales, respectively. Accordingly, the scale of S-NutLit-Tr was found to be reliable. To examine the two sub-scale factor structures of the S-NutLit-Tr scale, fit indices were examined: χ/df (1.246), GFI (0.923), IFI (0.975), TLI (0.967), CFI (0.974), RMSEA (0.046), and SRMR (0.055) and it was observed that the indices were within acceptable limits. In the analysis results obtained through the multi-group confirmatory factor analysis for measurement invariance, it was observed that the ∆CFI and ∆TLI values across all indices were less than or equal to 0.01. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults.
The study found that the scale of S-NutLit-Tr for young adults was a valid and reliable measurement tool in Turkish culture.
近期营养趋势的变化可能导致健康问题。特别是，年轻人不健康的饮食习惯表明后代可能面临风险。因此，营养素养的重要性和必要性日益明显。
本研究的目的是创建由Vrinten等人（2023年）开发的针对年轻人的简短营养素养（S-NutLit-Tr）量表的土耳其语版本。
本研究涉及伊斯坦布尔发展大学的115名年轻人，他们是通过便利抽样（一种非概率抽样方法）选取的。将原始的S-NutLit量表翻译成土耳其语后，在115名年轻人中测试了所确定因素结构的有效性和可靠性。使用克朗巴赫α系数检验内部一致性。采用验证性因素分析来验证两个子量表结构。最后，针对参与者的性别测试测量不变性，旨在确定该量表是否能捕捉不同群体的等效特征。
使用S-NutLit-Tr量表进行可靠性分析的结果显示，S-NutLit-Tr量表的克朗巴赫α系数为0.86。此外，“信息技能”和“专家技能”子量表的该系数分别为0.84和0.77。因此，发现S-NutLit-Tr量表是可靠的。为了检验S-NutLit-Tr量表的两个子量表因素结构，检查了拟合指数：χ/df（1.246）、GFI（0.923）、IFI（0.975）、TLI（0.967）、CFI（0.974）、RMSEA（0.046）和SRMR（0.055），观察到这些指数在可接受范围内。在通过多组验证性因素分析获得的测量不变性分析结果中，观察到所有指数的∆CFI和∆TLI值均小于或等于0.01。因此，观察到该量表的项目-因素结构、因素载荷、方差、协方差和误差方差对于年轻男性和女性都是等效的。
该研究发现，针对年轻人的S-NutLit-Tr量表在土耳其文化中是一种有效且可靠的测量工具。
