Is there a non-copyrighted alternative to the Childhood Trauma Questionnaire?

Childhood maltreatment is usually measured with the Childhood Trauma Questionnaire (CTQ). However, as far as I know, the CTQ is not in the public domain. Moreover, I may need to make some...

Measurement invariance of a bifactor model with categorical indicators. What is the recommended approach?

I have a bifactor model with categorical indicators: 4-option Likert-type items. One of my research objectives involves testing measurement invariance between two groups. I have been doing it as...

Why use a t-test if we can examine the confidence interval of the mean difference?

T-tests imply converting the raw mean difference to a "t" value, so that this can be compared to a pre-specified criterion for rejecting (or not) the null hypothesis. Isn't it basically the same...

What is measurement error in a CFA bifactor model if I plan to work with composite measures?

Bifactor models allow users to model both a general factor and several specific (or group) factors. The focus is usually on the general factor, which is what the measure was designed for in the...

Are at least three group factors necessary for testing a bifactor model within a CFA framework?

I understand that at least three first-order factors are needed for identifying a second-order, hierarchical CFA model. I also read in Reise et al. (2010) that at least three group factors are...

Does anybody have unpublished data using the 10-item Ruminative Response Scale (RRS)?

I'm working on a Spanish version of the 10-item RRS. However, an informal review of published results suggests that the proposed brooding-reflection model shows suboptimal fit. Does anybody have...

Where in the invariance testing sequence should correlated errors be included?

I am testing measurement invariance of a questionnaire. I am aware of the fact that some methodologists think it unnecessary to test for invariance of residual variances and covariances. However,...

How large should factor correlations be to attempt bifactor modeling?

There is an increase in the use of bifactor modeling to test for general factors in multidimensional scales. However, its use seems to make sense only when there are high correlations between...

Does it make any sense to examine skewness and kurtosis of Likert-type variables?

Researchers often examine univariate skewness and kurtosis of items prior to conducting factor analysis. Likert-type variables, however, are ordinal in nature and thus these statistics don't seem...
