不同的维度测量的是不同的性质，两者做两两比较有何意义，不同人群还比较有意义点

问卷是测量人的两者相反的特质，一正一反，看到有的文献上对正反进行了比较，说有差异，正的比较多，现在也在做这个问卷，就想问一下，有方法进行比较吗？

如果这样比较，采用配对样本t检验。

As I can understand when you say dimensions you mean factors. Factors are appropriate in order to reduce variability (here 14 items) using unobserved variables that is, factors. On the other hand,  you can use Principal Components (is a method that is related to factor analysis) in order to reduce the dimensionality. After that using factors you can use parametric methods (e.g t-test) if the assumptions are met or non-parametric if the assumptions are not met.
