Indicator Loading Values Unstable

Post by coupae » Tue Jun 07, 2016 12:58 pm

In testing a model with reflective constructs only, i noticed that the values of the indicators of some constructs will change dramatically (e.g., .8->.4 or even from positive to negative such as .7->-.1), when i change the way how other constructs relate to these strange constructs. Say, if i add a new path to allow construct B to affect construct A (one questionable construct), item loading values of the indicators of construct A will see dramatic changes --- which makes the results totally unreliable.

I am using smartpls 3. Any help is appreciated!!!!!!!
