dealing with second order construct which exist in theory
Posted: Tue May 03, 2016 7:21 am
Hi every one,
I hope i find an answer in your forum because I really have a big problem :
I have a second order construct which is multidimentionnal in the theory. up to here all is fine. When it comes to empirical issues I found low positive correlation between the 1st order dimensions which normally not allows me to build a 2nd order construct and a lack of convergent validity is up but the surprise when i test the second order construct and follow theory i found not bad value of regression weights between 1st and 2nd order (.4 to .7). so it does it mean that i am faced with formative LV ? can we increase correlation between 1st order dimensions or it's possible to consider the 2nd order and violate the rule of high correlation as recommanded by Jarvis & al (2003)? any advice on this knowing that in litterature it's always reflective contruct not the inverse. by the way I'm using smartPLS 3.
Thank you
