Q2. What future works have the authors mentioned in the paper "A new criterion for assessing discriminant validity in variance-based structural equation modeling" ?
Further research and concluding remarks Their research offers several promising avenues for future research. Against this background, future research should seek alternative means to consider formatively measured constructs when assessing discriminant validity. Apart from continuously refining, extending, and testing the HTMT-based validity assessment criteria for variancebased SEM ( e. g., by evaluating their sensitivity to different base response scales, inducing variance basis differences and differential response biases ), future research should also assess whether this study ’ s findings can be generalized to covariance-based SEM techniques, or the recently proposed consistent PLS ( Dijkstra 2014 ; Dijkstra and Henseler 2014a, b ), which mimics covariance-based SEM.
Q3. What is the reason for the MTMM matrix analysis not being a standard approach?
one-by-one comparisons of values in large correlation matrices can quickly become tedious, which may be one reason for the MTMM matrix analysis not being a standard approach to assess discriminant validity in variance-based SEM.
Q4. How does the Fornell-Larcker criterion detect discriminant validity?
It only detects a lack of discriminant validity in more than 50% of simulation runs in situations with very heterogeneous loading patterns (i.e., 0.50 /0.70 /0.90) and sample sizes of 500 or less.
Q5. What is the advantage of testing with confidence intervals?
As Shaffer (1995, p. 575) notes, “[t]esting with confidence intervals has the advantage that they give more information by indicating the direction and something about the magnitude of the difference or, if the hypothesis is not rejected, the power of the procedure can be gauged by the width of the interval.
Q6. What is the second approach to treat discriminant validity problems?
The second approach to treat discriminant validity problems aims at merging the constructs that cause the problems into a more general construct.
Q7. What does Chin argues that a standardized loading of 0.80 raises concerns?
He argues that, for instance, compared to a cross-loading of 0.70, a standardized loading of 0.80 may raise concerns, whereas the comparison of a shared variance of 0.64 with a shared variance of 0.49 puts matters into perspective.
Q8. Why should researchers reconsider the results of prior variance-based SEM analyses?
In the light of the Fornell-Larcker criterion and the crossloadings’ poor performance, researchers should carefully reconsider the results of prior variance-based SEM analyses.
Q9. What is the sensitivity of the approaches to assess discriminant validity?
As the correlations increase, the constructs’ distinctiveness decreases, making it less likely that the approaches will indicate discriminant validity.
