Discriminant validity of 2nd Order Factor
Posted: Mon Sep 02, 2013 6:25 pm
I realize this type of question has probably been asked before, but having read all the replies and associated links, I'm still a little unclear on how to tackle this issue.
I have a reflective-formative 2nd order factor within a model (as per p.231 of the PLS Primer by Hair et al) whereby the LOCs are measured by reflective indicators, and the LOCs have a formative relationship with the HOC.
All values within the entire model are absolutely fine, apart from the AVE of the 2nd order construct, which remains stubbornly just below 0.4.
Am I correct in thinking this isn't a problem? Some replies suggest AVE isn't required for a HOC, but others suggest I need to get it near to or > 0.5.
I've read the LRP paper by Becker et al (2012), but am still trying to arrive at the definitive view.
Any help much appreciated!
