Re: Significance of indirect effect in multiple mediator mod

Hi Dr. Becker, Thanks for your explanation about the sign corrections. When you say you "fixed" that issue, what does this mean exactly? That the software now changes the signs also for the indirect effect? Given that the sign corrections generally truncates the bootstrap distribution at z...

Re: Ipsative problem among indicators

Hi, It looks like you have compositional data (constant sum). Omitting one variable in the model may not fully resolve the associated problems. You may want to check out the literature on compositional data, where it is suggested to transform the data using log ratios (e.g., centered logratio, or is...

I think you should include the other constructs in the model as well so that you obtain their scores which you subsequently use as indicators in the second step.

Did you use the following formula to calculate effect size of a variable X on Y?

R2y (X included) - R2y (X excluded)

1 - R2y (X included)

Pae, From what I understand you have an endogenous Type II construct (which you call A) and some other exogenous constructs. Construct A is second order, formed by three first order factors that have reflective indicators. I think what you need to do is the following. First, use the repeated indicat...

This means that for construct GR, for example, item GR1 should not have any loadings on other constructs that are higher than 0.6739 (since its loading on the focal construct of GR is 0.7739). The same rule applies to all other item loadings.

One dimension dominates in seond-order formative construct

I have a model in which there is a Type II second-order formative construct (perceived control) with two sub-dimensions (personal control and social control) that have reflective indicators. To model this construct, I used the repeated indicator approach. Now the issue is that in the outer model ana...

Non-significant correlation but significant beta coefficent

Dear all, I have a model with several IVs, DVs and moderating variables. In one of the relationships, I find a significant path coefficients (beta) but the latent variable correlation is low and non-significant. Other than multicollinearity, what could explain these contradicting results? Thanks, Sh...

You should also conduct some tests of construct validity to determine the extent to which your measures correspond to the focal construct. For reflective constructs, you can look at the AVE values to establish convergent validity (should be higher than 0.5). You should also do tests of discriminant ...

You need to review your CSV file. You may have some extra columns in which there are no data. One thing you could try is to copy all visible data cells you have into a new Excel sheet and save as a CSV file before importing into PLS.

Interaction for constructs embedded in nomological network

Dear all, Suppoe you have the following model: 1) Exogenous formative construct A 2) Exogenous reflective construct B 3) Reflective Moderator M 4) Endogenous reflective construct D Suppose I want to model the interaction effect between A and M on D. Now since one of the two main effects is formative...

Re: Type II Second-Order Factor Model Questions

Based on my theory I have a type II model (reflective first-order LVs with formative second-order LVs). Some of the second order factors are exogenous and some are endogenous. The structural model mostly contains links between second order factors. This structure leads to my questions. Any referenc...
