The correlations between each item and the fixed eight factors are shown. The eigenvalues of each factor and its corresponding variance are also presented. Although the eigenvalues of the last factors were smaller than 0.7, there are correlations between the items and their factors. Exceptions are the following three items (marked witha and as well in boldface): TFI_6, TFI_22, TFI_5. The values less than 0.4 are italic
