In other words, the evidence of discriminant validity in the MTMM matrix can be found by weaker correlations between different traits measured by different methods in relation to correlations on the validity diagonal.
Ambos nao realizaram a MTMM completa pelo fato do Construto atitude ser reflexivo e nao possuir traco concorrente que justifique a dupla mensuracao, ao passo que utilizar mais de um metodo confere a validacao desejada.
CFA MTMM is performed by assigning items to their scales in the usual way (the traits side of the model), and assigning items which are the possible source of CMV (in our case, with similar wording) to a latent variable (the method side of the model).
Due to the negative relationship between SSE and other measures, absolute values were used for the MTMM analyses.
The method of choice for characterizing evidence based on relationships with other variables, as well as for completing an MTMM matrix, is often the Pearson correlation.
In the present study, dichotomous achievement goals and effort beliefs about the causes of sport success were added to the MTMM design to further test the predictive validity of the targeted measures of multiple achievement goals.
De acuerdo con Marsh y Grayson (1995), hemos comprobado y comparado los principales modelos del MTMM (ver Tabla 2).
MTMM was developed by Campbell and Fiske (1959) as a way to study trait validity across different assessment methods.
An MTMM matrix was then constructed on the basis of correlations between total scores by dimensions (see Figure 4).
Results show knowledge maps to be sensitive to students competency level, with mixed MTMM results.
At last I chose a model that falls outside the scope of the MTMM methodology, but worked out fairly well.
Other studies employing MTMM procedures do not, however, fully support Marsh's conclusions.
