Delete indicators to enhance discriminant validity

Post by Roelvdb »

Dear PLS experts,

I have a question regarding discriminant validity.After checking my factor loadings (and deleting those that did not exceed 0.55) I came up with positive reliability results (composite reliability >0.7) and adequate convergent validity (AVE>0.5).

One problem left: discriminant validity => 2 of my LV's seem to correlate a bit too much (r= 0,77 < √Ave = 0,72 & 0,75).

Since it's only a slight difference, I decided to delete two indicators whose cross loadings are higher on the wrong LV.

I ended up with sufficient discriminant validity, but is this an accepted procedure?

Thanks in advance
