Modeling moderating effects with formative indicators
Posted: Wed Dec 28, 2005 6:32 pm
There are a lot of posts in this forum about moderating effects with reflective indicators or with mixed measurement models, but what about formative indicators?
I've read the paper of Chin/Marcolin/Newstead about modelling moderating effects with reflective indicators and there is a hint on building moderator variables with formative indicators in the last chapter, but I'm not sure if I understand that correctly.
It says, that you should use PLS to create underlying construct scores for the predictor and moderator variables and then take those single composite scores to create a single interaction term. Does that mean you just export the latent variable scores of predictor LV and moderator LV to Excel, multiply the scores, get the data back to smartPLS and implement the Moderator as LV with one Indicator?
Would be a great thing if someone could help me here. Maybe anyone even knows some literature about Moderators with formative indicators, all I found was about reflective models.
Thanks in advance and have a happy new year!
