Hi,

I've performed EFA for my instrument, using PCA and varimax rotation. The KMO and Bartlett's test value were acceptable. Also, the items for each construct has achieved more than 50% of total variance explained. However, in the rotated component matrix, it is found that there are a number of items that load on more than one dimension. Does that mean these items should be omitted? Can i still keep them according to the maximum loading value (>0.4)? Thank you.
