1.The KayserMeyerOlkin KMO value should be higher than 0.5%
and the Bartlett spherical value should be significant with a pvalue less than 0,5%
see the file: xxxxxxxxxxxxxxxx-OK.xlsx
Black text (with language repairs/correction) in the work, and remove background color.
5. The last stage of exploratory analysis is verify if the correct number of factors extracted is higher than 0.6.

Should be significant (less than .05), p<0,001 indicating that the correlation matrix is significantly different from an identity matrix, in which correlations between variables are all zero.
Kaiser-Meyer-Olkin Measure of Sampling Adequacy is 0,749. Should be greater than 0.60 indicating sufficient items for each factor.
2. The commonality for every value should be higher than 0.4% ( Extraction )
These communalities represent the relation between the variable and all other variables (i.e., the squared multiple correlation between the item and all other items).

3. The total variance explained for factors have to be greater than 60% (here is 70,117%)
Eigenvalues refer to the variance explained or accounted for.
64,733% of the variance is accounted for by the first ten factors.
Percent of variance for each component before rotation.
Percent of variance for each component after rotation.
