HTMT in smartPLS 3

Post by janschreier »

I have a question regarding the confidence intervals in the bootstrapping Heterotraid-Monotrait-report (HTMT). Are these values adjusted by the Bonferroni-method or not? As I understand the options given under "confidence interval method" this relates to the distribution of the data itself and not the risk of getting and alpha error.
So if I have 10 constructs I would have to reduce the p-value to 0.005 if I wanted a 0.05 alpha-level with the Bonferroni method.
Could somebody please confirm this?

Thanks in advance!

The bootstrapp intervals for HTMT are not corrected by the Bonferroni-method. At the moment you have to adjust the p-level to match your model.

Dear All,

In my model I have four reflective constructs (including one moderator variable) plus four formative constructs, where the reflective constructs are the dependent variables (DV) respectively moderator variables (MV) and the formative are the independent variables. The assessment of discriminant validity by means of HTMT for the reflective measurement models results in the following HTMT values and confidence intervals:

MV DV1 DV2 DV3
----------------------------------------------------
MV
DV1 ,228
DV2 ,316 ,325
DV3 ,393 ,163 ,306
----------------------------------------------------

(1) DV1 => MV [-,106; ,391]
(2) DV2 => MV [,063; ,533]
(3) DV2 => DV1 [,231; ,495]
(4) DV3 => DV1 [-,034; ,315]
(5) DV3 => DV2 [,045; ,560]

Does this mean that (1) and (4) lack discriminant validity?

Many thanks in advance for your feedback.

No!

Please take a look at this OPEN ACCESS paper:

Henseler, J., Ringle, C. M., and Sarstedt, M. 2015. "A New Criterion for Assessing Discriminant Validity in Variance-based Structural Equation Modeling." Journal of the Academy of Marketing Science 43 (1): 115-135.

Dear Mr. Ringle,

Thank you for your reply. Do you have any recommendations on how to report HTMT in a PhD thesis. Shall I include just the results (e.g. HTMT matrix and confidence intervalls) or also the inter-item correlation matrix?

Best regards,
Judith

Hi

I would report the result as shown in the JAMS paper: The HTMT value and the confidence interval of each HTMT value.

Hi Pr. cringle
Wha do you mean by "JAMS paper"?
Thank you

Hi,

Just to give you a quick reply, JAMS (= Journal of the Academy of Marketing Science) where you can find the article on HTMT (http://link.springer.com/article/10.100 ... 014-0403-8)
