What information is included on a multitrait-multimethod matrix?

The multitrait–multimethod (MTMM) matrix contains the correlations between variables when each variable represents a trait–method unit, that is, the measurement of a trait (e.g., extroversion, neuroticism) by a specific method (e.g., self-report, peer report).

What is the multi trait multi method matrix used for in test validation?

The multitrait-multimethod (MTMM) matrix is an approach to examining construct validity developed by Campbell and Fiske (1959). It organizes convergent and discriminant validity evidence for comparison of how a measure relates to other measures.

How does the MTMM correlation matrix differ from the typical correlation matrix?

Essentially, the MTMM is just a correlation matrix between your measures, with one exception – instead of 1’s along the diagonal (as in the typical correlation matrix) we substitute an estimate of the reliability of each measure as the diagonal.

What is multi trait multi method?

The multitrait-multimethod (MTMM) analysis procedure is a powerful measurement design in construct validation research. The MTMM is a fully crossed measurement model whereby multiple procedures are used to measure multiple theoretical constructs in a large number of persons.

How do you measure discriminant validity?

The discriminant validity can be evaluated by using cross-loading of indicator, Fornell & Larcker criterion and Heterotrait-monotrait (HTMT) ratio of correlation.

What is criterion validity in psychology?

Also known as criterion-related validity, or sometimes predictive or concurrent validity, criterion validity is the general term to describe how well scores on one measure (i.e., a predictor) predict scores on another measure of interest (i.e., the criterion).

What is correlated uniqueness?

The simplest, the correlated uniqueness (CU) model, allow correlations among all indicators from a single method. This model, proposed by Kenny (1976) and Marsh (1989), is very general and does not explain the correlations but simply allows them.

What is discriminant validity and how is it calculated?

In psychology, discriminant validity tests whether concepts or measurements that are not supposed to be related are actually unrelated. A successful evaluation of discriminant validity shows that a test of a concept is not highly correlated with other tests designed to measure theoretically different concepts.

Do you want high or low discriminant validity?

In general we want convergent correlations to be as high as possible and discriminant ones to be as low as possible, but there is no hard and fast rule.

Are predictive and criterion validity the same?

Criterion validity compares responses to future performance or to those obtained from other, more well-established surveys. Criterion validity is made up two subcategories: predictive and concurrent. Predictive validity refers to the extent to which a survey measure forecasts future performance.

What is the Multitrait Multimethod Matrix used for?

Statistical technique used to examine construct validity. The multitrait-multimethod (MTMM) matrix is an approach to examining construct validity developed by Campbell and Fiske (1959). It organizes convergent and discriminant validity evidence for comparison of how a measure relates to other measures.

Who is the creator of the multitrait matrix?

Multitrait-multimethod matrix. The multitrait-multimethod (MTMM) matrix is an approach to examining construct validity developed by Campbell and Fiske (1959).

How are validity diagonals produced in multitrait matrix?

In Figure 1, three methods produce three validity diagonals: Method 1 by Method 2, Method 2 by Method 3, and Method 1 by Method 3. Third, the heterotrait-monomethod triangles are the light grey areas in Figure 1. These triangles contain bivariate correlations between different constructs applying the same method.

What are the considerations when evaluating the MTMM matrix?

There are six major considerations when examining a construct’s validity through the MTMM matrix, which are as follows: Evaluation of convergent validity – Tests designed to measure the same construct should correlate highly amongst themselves.
