I am performing a large (105 variable) factor analysis with factanal,
specifying promax rotation.  I kow that some loadings over 1.0 are not
unsual with that rotation, but I have some as large as 1.2, which seems
extreme.  I am skirting the assumptions of the model by using responses
on a 7-point rating scale as data; I may have to go back and compute
polychoric correlations instead of product moment, but before doing that
I would like to know if others have had equally large factor loadings
using data that are truly interval level data on continuous scales.
 
Thanks for suggestions or information,
 
Ben Fairbank
