hi,
formative constructs dont have AVE values. So check if the arrows flows from the indicators to the construct.

hi, only look your AVE, then delete one indicator. Then check if your AVE is >0,50, if not delete another indicator. This in reflective constructs. The literature say that you can conserve the indicator if outer loading >0,40, only do elimination if the AVE is <0,50, or Composite reliability is <0,7...

hello, How are you? if your Latent variable is a reflective construct, the score is: LV=(I1+I2+I3...+In)/n where: Ii: indicator i, and n: number of indicators. If you variable is a Formative construct. You have to see the outer weights (wi) of each indicator (i), the score is: LV=I1*w1+I2*w2+I3*w3.....

Hello, How are you? Actually you can use only one single item for a reflective construct (read Hair et al., 2014), but you wont have AVE and composite reliability. So, if you improve your AVE (>0,50) and composite reliability (>0,708) deleting those two indicators, it´s good. In my investigation i u...

I think you cant. did you only use the formative indicators ? The formative indicators act like independent variables and the reflective as dependent variables for the convergent validity. It´s a regression betwen the formative construct and reflective construc, where you analyze how well do the for...

if someone have the same problem i suggest to take a look at this: The Development of a Formative and a Reflective Scale for the Assessment of On-line Store Usability; Timo CHRISTOPHERSEN, Udo KONRADT; 2008. in that paper you can see that thay used reflective indicators for the same construct that t...
