Formative construct

Dear all, I have a formative construct (i.e., Efficacy) in my model. I propose that another reflective construct Movtivation has a direct relationship with Efficacy. Is this OK? I was told that, if you have a formative construct in your model, you should not have any direct structural path pointing ...

Hi Ralf, I am not sure if you still read this forum. Here is the formula how Chin(2010) uses F-test to examine the R² difference: F=(R₂²- R₁²/K₂-K₁) / (1-R₂²/N-K₂-1) with K₂-K₁ and N-K₂-1 degree of freedom Where R₁² is for the base model and R₂² is the superset model that includes the additional Lat...

My question is, which test should i run to test the differences of these two models? one more question: sa...

Hi there, just in case you cant access to the video.

low factor loadings and low AVE and low Cronbachs alpha

Hi everyone, I have a construct(reflective) which has three indicators. The loadings for three indicators are 0.036, 0.817 and 0.819. As you see, one is extremely low and,the AVE for this construct is 0.44, the composite reliability 0.62 and the cronbachs alpha is 0.41. All of them do not look good....

Hi everyone, I got a manipulation check (with 3 measurement items) and it is mainly to determine that the groups i am comparing are indeed significantly different (i.e. high level vs low level). I have been searching for related articles but mostly are experimental studies. I have no idea which test...
