Notes: 
Column Alpha - item refers to the Cronbach's alpha coefficients of the scales when the respective item is removed. 
Loevinger Hj coeff refers to the Loevinger's coefficients of item-scale consistency. 
Number of NS Hjk refers to the number of Hjk coefficients (i.e., Loevinger's coefficients between the respective item and
each of the other items of the respective dimension) which are not significantly different from zero.
